The insect collection of the Royal Ontario Museum of Zoology, at present comprising some 250,000 specimens, had its inception in the insect collection of University of Toronto Biological Museum. This collection was started by Professor William Hinks, first Professor of Natural History, when he established a natural history museum in 1853. At that time various collections of insects, mostly confined to exotic material, were donated or purchased.

Female. Compared with one from Milwaukee, Wis., Sept. 27 (S. Graenicher), it differs thus: the coarsely punctured shining clypeus without a distinct median groove; tegulae very dark brown (instead of clear red) ; stigma and nervures black or almost so; third discoidal cell more produced at end; hair on anterior border of hind tarsi conspicuously yellowish; basal hair-band of second tergite very broad; the abdominal band clear white. Anterior wing 7 mm. long.

Vanessa milberti Godart was described (1819, Enc. Meth. 9: 307, No. 25) from a specimen sent to the Paris Museum by the French painter and naturalist, Milbert, who visited the United States on one or more occasions early in the nineteenth century. Last summer, while in Paris, the type was photographed through the kindness of Dr. Le Cerf and this is reproduced on Plate 4, fig. I. Dr. Le Cerf informed the writer that the label was in the handwriting of P. H. Lucas who in 1860 re-labeled the collection, unfortunately destroying the original labels. This type is very badly worn so that today it might well pass for race furcillata Say for which reason the photograph of a typical specimen is also given (Plate 4, fig. 2).

More than fifty species of aphids are already known to attack the numerous kinds of Artemisia occurring in western North America. Some aphids and their ant attendants occur in great abundance, virtually blackening the affected parts of the plants attacked. Artemisia is only one of many forage plant groups occurring in Utah which is damaged by aphids.

In the mass of literature, dealing with the fall webworm there are few references to the number of larval stadia. Bruner ( I ) states that there are four or five molts in eastern Nebraska. Dyar ( 2 ), who made measurements of the head capsules, found seven stadia. Snodgrass (3) found six larval stadia. He figures the first, second, fifth, and sixth instars.

Differs from the typical section of the genus in the presence of a small fovea at the base of the male forewings (as in agrestaria Grossb.) and the lack of a hair-pencil on the hind tibiae in the same sex. Placed in this genus on account of the similarity of male genitalia, which are very close to those of serrataria B. & McD. as figured in my Studies in North American Cleorini.

During the last few days of July and the first half of August 1937 there occurred what probably has been the worst outbreak of the army worm. Cirphis unipuncta Haw. in this province. The damage was widespread and in many cases severe.
