AMERICAN LEPIDOPTERA. 17 



fully Texan. Erycina is an older name for splendldas, according to 

 Mr. Kirby. Under Phi/osaviia, used for a section of Hiibner's 

 Savila, we find cynthia, which is credited to Java only, though it has 

 been on our lists for years. Mr. Kirby has in some other cases given 

 only the original home of a species and not the localities in which it 

 has been accidentally introduced or domesticated. Samia Hiih. is 

 given cecrojiia as type, and Columbia, glovevl and califoniica as other 

 species. The last name justly replaces ceavothi Behr. In Callosa- 

 mia we find calleta, promethea and angulifera. This separation of 

 the species, which I have united under the term Attacus, is perhaps 

 justifiable when the fauna of the world is considered, though I con- 

 fess I rather doubt the possibility of sharp definitions for all of the 

 generic terms. Under Teleawe h?i.ve polyphemus.'A^ sole species and 

 type. Luna appears under Tropcea, and next to it we find T. rossi 

 Ross, from Toronto. It is extremely unlikely that this name refers 

 to a distinct species. I have not seen the " Cat. Lep. Can. p. 5, note 

 (1872)," where it is said to be described. Under Saturnia we find 

 our galbiiia, but it is credited to Mexico only. Calomturnia, with 

 mendocino as sole species and type, is separated from it by six foreign 

 genera. Axdomerix Hiib., is used to replace Hyperchiria for 77 spe- 

 cies, among which our few American names are scattered. Lillith 

 Strck. is given specific rank. Of Hyperchiria, proper, we have no 

 species. Hemileuca is an American genus, and all but four of the 

 species belong to our fauna. Nevadensis is given specific rank, and 

 hualapai, tricolor and sororius, are referred to Euleucophceus. E. 

 neumoegeni is referred to Argyrauges. In Pseudohazis, nidtali is given 

 specific rank ; pica is made a synonym of hera instead of a variety 

 of eglanterina, and marcata is made a variety of eglanferina instead 

 of hera, as its describer thought. It is to be regretted that Mr. 

 Kirby did not accept my limitation of the Saturniidse to those foi-ms 

 in which the aiitennjB have two branches or pectinations to each 

 joint. If structural characters are to be regarded as having any 

 value at all in the Lepidoptera, this character is certainly as strong 

 a one as occurs in the order. 



Family XXVI is the Lasiocampidaj, with 148 genera. Not until 

 we reach genus 85 do we find any familiar names, and then, under 

 Phyllodesma Hiib. we find the species we have as Gastropacha in our 

 lists. G. occidentis Wlk. is here referred as a synonym of americaua, 

 which I am willing to accept as correct. Roseata Stretch is used 

 instead of mildei Stretch, and here I cannot follow Mr. Kirbv. On
