Anthrenus VariusFab.—Entomologists generally are well enough acquainted with the appearance of this insect, and but too well with the work of its larvæ; but as to the time required for its development there is not the same unanimity of knowledge,—some stating that it requires a year for its various transformations; others, that only a few weeks are necessary. The following is my experience: May, 1879, I placed a female in a paper collar box with some refuse Coleoptera and Lepidoptera. This box stood on the mantel-piece in my office, and consequently the temperature was nearly uniform summer and winter. An examination two months afterwards revealed several small larvæ. These were inspected monthly, and appeared to have attained their growth by the 1st of December, though they remained active during the winter. The first pupæ were observed March 5th, and the first beetle on the 26th. From that time to May 1st thirty-five developed in all,—the product of this one beetle. Three females and two males were left in the box, and six weeks afterwards young larvæ were observed. They were inspected monthly, and followed the same course as observed the previous year. From April to May, (1881), seventy-five beetles were taken from the box. How many were left in unknown.

I was much interested in an article in Vol. xiii. of the Canadian Entomologist, by Mr. W. H. Edwards, entitled. “Is Limenitis arthemis double-brooded?” My own observations previous to the time of reading the article were confirmatory of Mr. Edwards' theory; but I wished to learn more of this interesting species before hazarding any remarks concerning its habits.

I have never reared or attempted to rear arthemis from the egg, but have one specimen obtained from a full-fed larva found on the 2nd July, 1877. It went into chrysalis on the 3rd, and the imago appeared on the 16th, I have seen fresh looking specimens on 1st July, when enjoying, with other citizens, “Dominion Day” in the country. Later than this I have not seen a fresh specimen, excepting the example before recorded.

Through his Lordship's kindness, I have received, with much pleasure, a copy of the above named brochure. From such examination as I have been able to give it, it seems to me by far the most valuable of recent contributions to the literature of American Tineidœ, and place all students of this beautiful group of the “Micros” under special obligations to its distinguished author.

The material examined in the preparation of these “Notes” consisted mainly of the loaned collections of Profs. Fernald and Riley, that of the Peabody Academy of Sciences of Salem, Mass., of Mr. Goodell, of Amherst, Mass., and a small contribution by the present writer. Each of these lots contained some of Mr. chambers' types. The only American collections of any note which were not represented were those of the Harvard Museum at Cambridge, Mass., and the Clemens' types at Philadelphia. Of the latter, however, Lord Walsingham had full notes made during his visit to this country i 1872.
