ratherlarge; second submarginal cell high, receiving second recurrent 
nervure almost at apex, and first quite a long way from base.

Glyptapis f uscula sp. nov. 
Black; length a little over 5 mm ; agrees in general with G . mirabilis, 
e. g. in general build, short thick antennae, hairy eyes, strongly curved 
lower end of basal nervure, strongly sculptured thorax, ridged meta- 
thorax, etc. The sculpture of the metathorax, so far as visible (the 
hindmost part cannot be seen) is similar to that of G. mirabilis. The 
longer bristles of front are very strongly plumose. 
Compared with G. mirabilis, the large punc- 
tures of mesothorax are smaller and less dense, 
and the surface between them is very densely and 
minutely punctate. 
The scutellum is sparselypunctured in the middle, 
and its hind part is beset with black bristles. There 
are strong bristles on the ventral surface of abdomen. 
The wings are strongly darkened, and the venation differs from 
that of G. mirabilis. Second submarginal cell comparatively high and
