A New Fossiv Moth from Florissant 
17 
point; median cell short, its lower apical corner emitting M 2 ; 
M 3 , Cui a and Cui B (in sense of Tillyard) coming off as in related 
genera, Cui A distinctly nearer to M 3 than to Cui B . 
FIG. 1. ADELOPSYCHE FRUSTRANS SP. NOV. 
Adelopsyche frustrans new species. 
Anterior wing 15 mm. long and 4.5 broad, probably brown 
or dark gray in life; hind wing about 9.7 mm. long; width of 
thorax and abdomen, which are dark, nearly 4 mm.; legs not very 
robust. 
In having the veins R 2 ,. R 3 , R 4 and R 6 all arising separately, 
this differs from the American genera (which are well figured by 
Barnes and McDunnough) and resembles the Australian genus 
Macrocyttara Turner (Trans. Ent. Soc. London, 1918, p. 169). 
It differs at once from Macrocyttara in having Ri arising before the 
radial cell (as in Givira and other genera), and R 4 and R 5 arising 
below it. The separate origin of Ri is considered by Jefferis 
Turner to be more primitive than the condition in Macrocy- 
ttara. Outside of Macroscyttara, the nearest allies of our fossil 
are Cossodes (Australia) and Dudgeona (Australia, India, Africa) ; 
these however are very distinct. The fossil genus Gurnetia 
(Cockerell. Ann. Mag. N. Hist. June 1921, p. 472), from the 
Isle of Wight, agrees in having the branches of the radius sep- 
arate, while R 6 and M x come from beneath the radial cell. Cui 
and Cu 2 of my figure of Gurnetia are Cu XA andCui B of Tillyard.
