Differing from the $ mainly in the wings which are completely 
hyaline except for a brownish edging behind the marginal vein. The 
abdomen is dorsally dull only the sutures being smooth. Disc of 1st 
tergite with closely set fine punctures and a patch of coarse setigerous 
punctures at each side. The other tergites bear 2-3 row s of large punctures 
with finer ones between. Of colour differences the most conspicuous 
is in the entirely black funicle.

A. desinicfor is closely related to A. (Stomatoceras) magrettii 
Kirby, (Journ, Linn. Soc. Lond. Zool. Vol. XX, p. 35, (1880) but in the 
African species the first (adbasal) of the spots on the forewing forms a 
complete band while the second extends to nearly three-fourths of the 
width. The first abdominal tergite is distinctly and densely punctured 
both on the disc and more coarsely on the overlaps, the whole surface 
appearing much duller than in A. destructor.

5 . Black, the last 2 segments of the funicle, the edge of the tegulae 
lackish brown. Wings slightly tinted, with a blackish brown spot 
from the uprise of the marginal vein to the club of the radius and only 
a little broader at its maximum, than the length of the radius. Tarsi 
blackish brown, the joints darkest dorsally and paler towards their 
apices ventrally.

This species is the largest and darkest of a group in which the scutellum 
shews a longitudinal median crenulate sulcus, the crenulation being 
produced by contiguous umbilicate punctures which elsewhere on the 
scutellum are more sparsely set with smooth gleaming interspaces. 
At its posterior end the sulcus divides the apex into two rounded lobes but 
the scutellar plate is only narrowly developed. The post marginal 
vein is distinctly longer than the marginal from which a single transverse
