is shorter than one-half the length of the wing. The clasper is 

 absent in the male genitalia, and the ductus bursae of the female is 

 partly sclerotized. In BorJchausenia veins 2 to 5 of the fore wing are 

 equidistant, 10 is near 9, 11 is from about middle of cell, and the 

 internal cell is present. In the hind wing 3 and 4 are approximate 

 and the cell is about half as long as the wing. In the male genitalia 

 the clasper is present and in the female genitalia the ductus bursae 

 is membranous. 



The genotype is the only species I have seen referable to this 

 genus.

Labial palpus, antenna, face, head, thorax, and fore wing straw 

 colored, shining. Second segment of labial palpus shaded with black- 

 ish fuscous exteriorly on basal half. Antenna indistinctly and nar- 

 rowly annulated with fuscous. Fore wing irrorated with blackish 

 fuscous; base of costa, a large spot at basal third, in cell, and one 

 at end of cell, blackish fuscous; cilia straw colored, more ochreous 

 basally. Hind wing pale light fuscous ; cilia ochreous basally fading 

 to straw color outwardly. Legs straw colored, strongly overlaid 

 with blackish fuscous exteriorly except at joints and on hind tibia 

 and tarsus. Abdomen shining whitish-ochreous. 



Male genitalia. — Harpe narrow ; cucullus rounded. Anellus deeply 

 incised on posterior edge. Aedeagus large, stout, sharply pointed, 

 sharply curved basally; vesica armed with a single, long, sharply 

 pointed, strong cornutus. Vinculum narrowly rounded. Gnathos 

 very broad, shovel-shaped and very closely approximated to the 

 slender, pointed uncus. 



Female genitalia. — Genital plate membranous. Ostium broad, an- 

 terior edge concave. Ductus bursae slender, twisted, sclerotized in 

 posterior two-thirds, the sclerotized portion bearing numerous small 

 teeth on inner surface ; ductus seminalis entering well before ostium. 

 Bursa copulatrix large, oval; signum a weakly sclerotized, toothed 

 plate.
