Falls Church, Virginia (reared under Hopk. U. S. no. 12162, April 

 8 to 30, 1915, from larvae feeding on leaves of Ilex verticiUata^ Hein- 

 rich, collector). 



The pupa is quite characteristic with large, protruding orange yel- 

 low spiracles. 



22. Genus RHOPOBOTA Lederer. 



(Figs. 6, 37, 416.) 



Genotype. — Tortrix naevana Hiibner. 



SynonTTiy, — Eud&mis Authors (not Hiibner). 



Fore wing smooth; termen deeply concave at 5 and 6; apex 

 pointed but not falcate; 12 veins; 7 and 8 stalked; 10 from cell mid- 

 way between 9 and 11; 9 approximate to 8; 11 from cell at, or just 

 before middle of cell; upper internal vein of cell nearly obsolete, 

 from between 9 and 10; 3, 4, and 5 closely approximate at termen; 

 2 bent up slightly toward termen ; no costal fold in male. 



Hind wing with 8 veins ; 6 and 7 approximate towards base ; 3 and 

 4 stalked; in male a shading of coarse black scales on underside of 

 wing along upper vein of cell (fig. 6). 



Male genitalia with a row of stout spines on outer surface of harpe 

 just above lower margin; rudimentary clasper present. Uncus bi- 

 furcate; arms widely separated, rather short and weakly chitinized 

 (slipper shaped). Gnathos reduced; fused with socii. Socii greatly 

 developed; porrected (posteriorly projecting); ends of arms meet- 

 ing in hairy knob-like projection. Aedoeagus straight; moderately 

 long; fairly stout; cornuti a cluster of elongate spines. 



A distinct genus. Close to Norma and Kundrya but at once to 

 be recognized by its peculiarly developed socii.

The purely European synonymy is omitted from the above list. 

 I have elsewhere noted the identity of our vacciniana with the 

 European naevana and given full description of larva and pupa. 

 In Europe the larva is reported as feeding on black thorn, holly, and
