116. Stenorrhoe longipenxis (Warren). 
Stenorrhoe loiKjipennis, Warren, Nov. Zool., vii, 183 (1900). 
Goya, Corrientes, in coll. Br. ^lus. 
The species was described from S.E. Brazil. I know of 
no other localities. 
Eueupithecia (Berg, MS.) (Prout), nov. gen. 
Face Hat, not tufted ; jJ^dpus very short, porrect, 2nd joint rough- 
scaled, 3rd joint small ; tongue short ; antenna in ^ with strong 
fascicles of cilia, a longer and a shorter pair of fascicles to each joint, 
in 9 very shortly ciliated. Thorax glabrous beneath ; femora 
glabrous ; hindleg short, hindtibia in ^ with hair-pencil, all spurs 
wanting, in 9 'vith terminal spurs only. Abdomen long. Wings 
long and narrow, smooth-scaled ; frenulum developed. Forewing 
with cell long ; SC' from about two-thirds of cell ; SC‘^ out of SC'i 
anastomo.sing with SC-'' to form a long, simple areole ; SC'*® from 
welPbefore apex of cell ; radials normal ; M' a])proximated to ; 
M” approximated to M', noticeably curved. Hindwing with cell 
rather long ; C anastomosing with SC to beyond one-half of cell; 
SC‘^ stalked with R' ; R^ from much a1)ove middle of cell; medians 
nearly as in forewiug, M- less curved. 
Type of tlie genus: Eueupithecia cis 2 )latcnsis, Prout, 
nov. sp. 
According to my invariable custom, I liave adopted an 
available MS. name in preference to coining a new one; 
but it must be admitted that Berg’s name is by no means 
elegantly formed. 
This interesting genus bears much superficial resemblance 
to some of the narrower-winged species of Eu]}'ithecia and 
Encymatoge, except in its more elongate abdomen; yet its 
smooth, flatly-rounded face, minute palpus and aborted ^ 
hindleg, all recalling the Acidaliinae, remove it rather 
widely therefrom. It is perhaps related to Stenorrhoe, 
Warr., Nov. Zool., vii, 183, which shares with it the frontal 
and hindtibial structure (I know only one 9 of Stenorrhoe, 
with the legs lost), but which differs in having the areole 
double, and in some other points.
