REVISION OF SPECIES OF THE GENUS AGROTIS. 37 



belongs here, I should not be surprised to find a considerable modifica- 

 tion of the male genitalia when that sex is studied. Unfortunately I 

 had no male. 



Rhynchagrotis crenulata Sinitli. 

 1887. Siuith,Proc.,U. S.Nat. MiiH.,x,ir.l, Aurotis. 



Primaries deep dark brown ; basal and s. t. space slightly i)aler, 

 powdered with gray ; costal space paler red brown ; ordinary spots 

 I)owdered with gray; claviform outlined with pale yellow scales. Trans- 

 verse lines distinct; t. a. lines geminate, included space pale; t. p. line 

 crenulate, course as in the preceding species; s. t. line distinct, pale 

 yellowish, punctiform. Basal black dash distinct; cell black. Second- 

 aries smoky fuscous. Ilarpes of ^ as in the preceding species; but the 

 projections at up[)er and inferior angles are longer, and there is an 

 additional curved slender projection from upper margin. The clasper 

 is lacking, but is replaced by a quadrate corneous plate. The additional 

 projection of side piece probably serves the same purpose as the clasper 

 of preceding species. 



Expands 35"""; 1.4 inches. 



Habitat. — California. 



This is the facula of Mr. Neumoegen's collection, so named by Mr. 

 (rrote. The dill'erences are so obvious, that there seems scarcely an 

 excuse for the error. The difiereuce in the $ genitalia is very decided 

 also. 



In the latter character this species and confusa agree closely, and 

 tliey dilfer from all the preceding by (he additional linger-like process 

 of the harpes and by lacking the corneous hook of the clasper, the 

 latter being represented by a subquadrate, slightly projecting plate. 



Since the above was first described I have seen many specimens and 

 there is a possibility that perhaps this species and the following — con- 

 fusa — may turn out to be identical. I am not readj"^ to say that it is so, 

 but as the genitalia agree, and the difference is in maculation merely, 

 there is a strong likelihood that it may be so.

Bright red brown; costa and collar broadly pale yellow; cell before 

 and between the ordinary spots black; ordinary spots concolorous, 

 narrowly annulate with pale yellow; claviform outlined in same way. 

 T. a. line distinct, not crossing costal pale space, but incurved to base; 

 t. p. line punctilbrm, indistiiu't, geminate, in(;liuled space paler; s. t. 

 line pale yellow, narrow, powdery, emphasized by the somewhat darker
