CERTAIN BUTTERFLY GENERA — FIELD 107 



the related genera in the form of the claws, paronychia, and piilvilli 

 as well as in habitus. 



Venation: Figure 17. Forewing with four radial veins, Rg having 

 anastomosed with R4; Ri long, only slightly shorter than R2; R2 from 

 apex of cell or very close to the apex; M2 from well below apex of cell. 

 Hindwing with Cu2 from distinctly beyond middle of cell and not 

 opposite to origin of Rg and with distance between bases of Sc+Rx 

 and Re about equal to distance between Cu2 and M3; distance between 

 bases of Cui and Cu2 greater than distance between bases of Rg and 



Legs: As in Tatochila with a pair of apical spm-s present on mid 

 and hind tibiae. Paronychium (fig. 25) about as long as claw and 

 broad, about one-half as wide as its length and broadly rounded 

 distally. Claw (fig. 25) directed somewhat outward and with its 

 dorsal margin greatly arched, its long axis nearly parallel to basal 

 margin; extremely short and thick, only about twice as long as its 

 width at base. Tooth somewhat divergent from distal portion of 

 claw and originating from distinctly beyond middle; about equal in 

 size to distal portion of claw, with dorsal margin of tooth about equal 

 to width of claw at base. Pulvillus (fig. 25) broad, much broader 

 than base of claw. 



Genitalia: Male (figs. 1, 9) with uncus short, distinctly shorter 

 than greatest width (ventral or dorsal view) and equal to about 

 one-third the length of tegumen; distal half of uncus finger-like, 

 gradually tapering, not distinctly swollen behind tip and lacking 

 the lateroventral internal ridges or infoldings of the lateral walls 

 found in Tatochila, Hypsochila, and Phulia (Phulia); harpe acuminate; 

 subscaphium absent; anellus with a dorsal plate which together with 

 the ventral plate completely surrounds the aedeagus; aedeagus in 

 lateral view very broad and flat distally, at least twice as wide as in 

 the middle. 



Female (fig. 34) with ductus biirsae as long as bursa copulatrix (ex- 

 cluding the accessory pouch), not sclerotized except posteriorly where 

 there is a large bulbous structure containing the ostium and to which 

 the ductus seminalis attaches dorsally; eighth tergite entire and 

 eemiannulate; eighth sternite with outer genital plate laige and 

 smooth; inner genital plates enthely setulose on outer surfaces and 

 each divided into a posterior finger-like lobe and an anterior lobe that 

 has its posterior margin nearly parallel to the finger-like lobe. 



Habitus: Wings white above with apex of forewing fuscous and 

 without a distinct silvery white sheen except at base of wings. Male 

 with both wings mainly white to pale yellowish white below. In 

 the female this yellow is somewhat stronger. Black discocellulai* 

 spot missing on both surfaces of forewing in both sexes. With a
