A GENERIC REVISION OF THE HIPOCRITID^ (Arctiid/e). 



BY HARRISON G. DYAR, PH. D. , NEW YORK. 



The earliebt use of the term Arctiidje is referred by Dr. Packard to 

 Leach (1815). This is antedated by Hiibner's Tentamen terms, Hipocritse 

 and Hypercompse. The latter is unavailable, as Hypercompa becomes a 

 synonym. I do not find any plural terms for the family before Hiibner. 



The faunas of Europe and America are here united. I have included 

 the Indian genera as far as possible, but could not do so completely, as 

 Hampson's work is much less available here than usual. Hampson does 

 not recognize the Lithosiidae on the character of the absence of ocelli, but 

 unites under the term Arctiidje all the species here grouped as Hipocritidse 

 with Lithosiidre, Nyctemeridje, Pseudoipsidie and Nolidre. His subdi- 

 visions of this aggregation are based on other characters, so that some of 

 the genera that I have not seen can not be placed in the 'table from his 

 figures and descriptions. Especially Castalba, Tatargena, Sidyma may be 

 Hipocritidse, though placed in Hampson's Lithosiinae, while Rhodogastria, 

 Pangora, Nicaea and Leucopardus I can not place from lack of the type 

 species. I do not think that this affects the present revision, as these 

 genera seem to be distinct from any of those included. As far as the 

 American genera are concerned, I exclude Cydosia and Cerathosia, as 

 they are probably Noctuid. Euverna is transposed to the Arctiinae and 

 becomes synonymous with Ectypia, a result due to the study of additional 

 material, which I owe to Prof Smith. Cycnia divides into three genera 

 on venational characters, one of the sections supplanting Pareuchaetes ; 

 Halisidota divides into two genera. The names Elpis and Neoarctia fall 

 before European terms and a new genus is required for the species 

 vlrginalis, Boisd. Pygoctnucha is transferred from the Euchromiidae on 

 account of the presence of vein 8 of secondaries. Three genera, Eucereon, 

 Bertholdia and Euerythra, lack vein 8 and would seem strictly to be 

 Euchromiidae, but I hesitate to transfer them, as the habitus is Arctian, 

 the larvee are unknown and the condition of vein 8 is distinctly led up to 

 in Eupseudosoma, which has a short spurlike vein 8 in the male and none 

 in the female. The Phaegopterinae may be further modified when the 

 large South American fauna is worked up. In the meantime I dedicate 

 to Mr. Schaus the new section of Halisidota, which he has shown to be of 

 generic value (Journ. N. Y. Ent. Soc, IV., 138) in recognition of his 

 work on this group as well as on the allied Euchromiidae and in the anticipa- 

 tion of still further and more comprehensive labours.
