HEL.IA, Guenee. 

 The shortly and evenly pectinated % antennae, bristled in 9 , and 

 the heavier and longer arcuate labial palpi, separate our single com- 

 mon species from the two referable to Epizeuxis. In a restricted 

 sense I retain this generic term for Helia phaealis, Guenee. 



llelia phaealis, Guenee. — % 9 • — Primaries silky blackish brown crossed 

 by three undefined dentate pale yellowish lines. A pale lunate discal mark 

 outwardly denned. Secondaries pale fuscous, with two diffuse darker shade 

 bands. Beneath pale fuscous, with two common exterior shaded bands and 

 dark discal marks. Legs outwardly brownish with pale dots. Expanse 26 to 

 34 m. m. 



Habitat. — Eastern and Middle States. Of frequent occurrence and 

 casually resembling Aglossa. 



I have so far in these papers noticed many deltoidous genera of 

 North American Noctuidae ; I give here a list of species found in our 

 Territory, omitting the unrecognized descriptions written by Mr. 

 Walker. 



The species hitherto referred to Herminia are susceptible of generic 

 division. For Herminia morbidalis Guenee, the term Chytolita is 

 proposed. The species differs from Pechipogon Hiibner, the type of 

 which is the European P. barbalis, in its neurational characters as 

 mentioned by Guenee, p. 56. For other species the term Zanclogna- 

 tha, Lederer, is retained. It seems to me that this is founded on 

 European types strictly congeneric with our American Herminia cru- 

 ralis Guenee, and I use it in this sense here. Herminia Latreille, 

 seems to be now used for the European PI. tentacularis; since I re- 

 gard H. longilabris as generically distinct I retain the latter as the 

 type of Philometra. Oleptomita seems to fall in between Zanclognatha 

 and Philometra; while, owing to defective material, I am yet pre- 

 vented from announcing new allied North American forms. 



I close the series of genera with Tortricodes, from the consideration 

 that the cleft primary is a degradational character. In other respects 

 the genus is allied to Epizeuxis. But it is as yet too early for me to 

 offer argument upon the natural sequence of the genera. 



Mr. J. A. Lintner, whose conscientious Entomological Reports 

 merit approval, writes me that he has both sexes of Tortricodes bitida- 

 lis with cleft primaries. I then refer T. indivisalis to Heterogramma, 

 Guenee, believing our species not to differ generically from the Bra- 

 zilian species which M. Guenee uses for his type.
