Ceratocapsus quadrispiculus Knight (1927, 
p. 148). 
This species is allied to uniformis Knight, 
and is very similar to it in size and colora- 
tion, but differs in having strongly arcuate 
emboliar margins, a somewhat shorter ros- 
trum and a uniformly pale, smoky mem- 
brane; the genital claspers are distinctive, 
fig. 134.
