The present list of writings of the late Henry Edwards was compiled up to 1880 by the deceased, and the titles following were added by me. Mr. Edwards, at the time he gave me the list, told me that it lacked the titles of one or two articles he had written for some newspaper in Australia a number of years ago, but could not remember on what subject they were, nor in what paper he published them. His papers on Pafific Coast Lepidoptera, Nos. 23 to 30 inclusive, were not published by the California Academy of Sciences, except as author's extras.

There being no published list of the American species of Thysanoura, I have thought it advisable to bring my notes together in a connected form. The names adopted are based on a careful study of many specimens from all parts of the country, and the arrangement of families and genera is a combination of that of Tullberg, Lubbock, and Comstock. I have preceded the catalogue by a list of the more important papers containing descriptions of American species, and I have followed the names of all those species known to me by an exclamation point.

In the Trans. Am. Ent. Soc. I offered a revision of the species of this genus, in which I reduced the number of species to five; but, from recent experience, I am of the opinion that this number will have to be still further reduced. I have bred a moth that forms an intergrade between P. elegans and P. fusca, and have noticed no difference between the larvæ that produces geminata and albipunctata.

Heterochroa californicaButler.

Egg.—Nearly spherical, flattened a little at base; covered with hexagonal elevated reticulations, from the intersections of which arise short spines. Colour uniform leaf-green, with a silvery lustre; width 1.5 mm. Laid singly at the tip of a leaf on the upper side. Duration of this stage eleven days.

In describing C. retecta and C. flebilis, it appears from Mr. Hulst's statements, that I included certain dark shaded specimens, one or more or retecta, under flebilis. Mr. Hulst says:-“The typical specimens in Phila. cover both species.” This may be true, as also that Mr. Strecker figures a dark shaded retecta as flebilis. I have not his work. But there is not doubt in my mind as to what was flebilis, and there is no excuse for Mr. Hulst's renaming my species as luctuosa.

Last year (1890) I spent the months of July and August at Inverness—a saimon-canning station at the mouth of the River Skeena, and paid what attention I could spare to the beetles of the locality, a list of which I give below. For the identification of my specimens I am indebted to the courtesy of the British Museum authorities at South Kensington.

In the proceedings of the Entomological Club of the A.A.A.S. at Washington, published in Canadian Entomologist, page 220, it is stated that I mentionded a suspicion that Asopia farinalis fed in clover, and asked if any one present had any knowledge of the matter.
