We use contingent valuation to estimate hunter and trapper willingness to pay (WTP) for a hypothetical bobcat harvest permit being considered in Indiana. Harvest permits would be rationed, with limits on aggregate and individual harvests. A model of permit demand shows that WTP may be subject to “congestion effects” which attenuate welfare gains from relaxing harvest limits. Intuitively, relaxing limits may directly change an individual’s expected harvest and, hence, WTP. Participation may subsequently change, with congestion offsetting welfare increases. These effects may lead to apparent scope insensitivity that may be endemic in the context of rationed goods.

The following species of Acridiidæ were recently purchased by the writer from the collector, Dr. R. E. Kunze, of Phœnix, Arizona. There are thirty-two specimens, representing eleven species, one of which is apparently undescribed, representing a new genus. Several of the species are, for various reasons, quite interesting and all are herein listed. They are as follows:

1.—Hippiscus leprosus, Sauss.

Xanthippus leprosus, Sauss. Prodr. Oedip., 92 (1884).

Hippiscus leprosus, Scudd. Psyche, VI., 334 (1892).

One female; Pinal Mts., Gila Co.; July 24, 1900.

This species was determined by Mr. J. A. G. Rehn, of Philadelphia.

Too late for correction, I find that in my recent paper on western Orthoptera* I have redescribed Scudder's Aulocara rufum as a new species under the name guanieri, placing it in the not very nearly related genus Heliastus. This unfortunate mistake was brought about by the uncertain position of the genus Aulocara, which possesses both tryxaline and Œdepodine characters. The generral aspect of the species of the genus is certainly very strongly œdipodinean and the characters of the declivate vertex, subperpendicular front, filiform antennæ, small round eyes, obsolete lateral carinæ, twice or thrice severed median carina, wrinkled pronotum, and of the generally present intercalary vein, all indicate close affinity to the Œdipodinæ.

Sinea complexa, s. sp.—Length, ♂, 8 to 9.5 mm., ♀, 9.5 to 11 m.m; width, ♂, 3 mm., ♀, 3.5 to 4.5 mm. General colour ranging from a very dark brown to pale cinnamon. Head armed with three pairs of anteocular spines, the posterior pair the longest, with smaller ones interspersed. Behind the eyes, with several sharp spines, one near each ocellus being almost as long as those of the posterior anteocular pair. Neck spinose. Antennæ somewhat pallid, with a slight rufous cast at the distal ends of the segments.

Melanoplus Browinii, sp. nov.– General colour brownish fuscous. Head slightly prominent, witht the occiput elevated a little above the pronotum and with a black postcular stripe; interspace between the eyes no broader than the basal segment of the antennæ' fastigium moderately declivent and deeply sulcate except above, where it is biseriately punctate. Eyes large and somewhat prominent, distinctly longer than the infraocular portion of the genæ. Antennæ long, in the male as long or longer than the posterior femora. Pronotum equal in the anterior portion, but quite noticeably expanding on the metazona, truncate anteriorly, posteriorly obtuse angulate, the angle rounded; lateral lobes marked with a more or less interrupted black stripe which is continuous with the postocular stripe of the head. Median carina distinct only on the metazona, which is shorter than the prozona. Prosternal spine suberect, pyramidal, apically acuminate.

The genus Eremopedes was established by Scudder in 1894, CAN. ENT., XXVI., p. 178,181. It was founded on a femal specimen in the National Museum, but the species was not described till 1900. Previous to that date Mr. Cockerell described a species from New Mexico, together with a colour variety of the same, and I can now add a third species to the genus. In connection with its description it may be well to give a short account of the genus, which may be characterized as follows:

Insects of medium size. Head with the fastigium moderately prominent. Thorax with the prosternum unarmed.* Pronotum smooth, moderately rounded, nearly as much arched posteriorly as anteriorly, and without carinæ. Legs moderately spinose, hind pair long, the femora extending far beyond the tip of the abdomen, usually as much as half their length. Fore tibiæ spinded above on the outer margin only, the spines three in number. Ovipositor moderately curved upwards.

On the 21st September, 1891, on opening a small box of neglected insects, etc., I caught a glimpse of several minute black files as they flew out. At the time I could not imagine what they were. The next day I collected a lot of pupæ of Tachina flies and enclosed them in tin boxes to transform to imagines, but instead of the perfect fly appearing, the boxes were filled with the same small flies as I had observed issue from the opened box on the day previous, and then, as I remembered having had some of those Tachina puparia in the box, I readily understood whence the flies came.

Ischnoptera adusta, n. sp.—Description—Male: Colour dark yellowish, with eyes black and the disc of the pronotu slightly mottled with fuscous and the tips of the elytra and wings fuliginous. Anterior femora beneath of the inner margin armed on the apical two-thirds with about ten semiequal, equidistant spines, the basal third unarmed. Subgenital plate roundly incised apically; apical styles long, slender rigid spines extending about half their length beyond the apex of the subgenital plate; cerci long, fusiform.

Last summer, on August 24th, a few hours were spent at Moose Jaw collecting Orthoptera. But few species were taken, and they are here listed for the locality. They were all taken on the open prairie, out a short distanace from the town.

An inexcusable blunder was committed by me some years ago. On page 791, Proc. U.S. Nat. Mus. XXVI, for 1903, I described an insect under the name Psinidia sclciforns, var. amplicornis. For the word sulcifrons the specific name fenestralis was intended, and should be subsituted throughtout the description.

Salganea humeralis, new species.— Size medium. General colour black, the under surface of the legs and of the body, except the last abdominal segment, or subgenital plate, and the mouth, except the mandibles, and also the vertex, reddish. The base of the elytra in the anal field is also tinted with reddish. Antenna♀ dark, hairy. Wings and elytra mostly missing. Anterior femora unarmed.
