The upper side of the abdomen may be described as of a brown colour, 
with the lateral and posterior edges and an ill-defined longitudinal 
central band of fleshy ash: it is thickly clothed with minute black 
hairs on the disk, and with long ones at the base and sides. The 
wings and their veins are coloured as in Gl. morsitans.

This species is very much larger than either of the preceding. The 
head is comparatively much smaller and the wings much larger; the 
front of the head is dusky; it, as well as the basal joints of the an- 
tenn, is rather thickly clothed with black hairs; the arista of the 
antenne is luteous, with a dark line behind, and the brantling sete 
with which it is furnished are black; the palpi are thickly clothed 
externally with short black sete; the thorax is dark greyish brown, 
also very thickly clothed with short black setee and long curved lateral 
bristles ; the back of the thorax is marked with a dark central lon- 
gitudinal line, having a less distinct one on each side of it, between 
which and each side are two large brown spots, one behind the other ; 
the scutellum is paler, and marked with two ill-defined dusky spots ; 
the wings are stained brown; the legs are dirty luteous buff; the 
tibiz marked with one, and the tarsi with three very delicate longi- 
tudinal black lines ; the tibize are compressed, and the black line oceu- 
pies the superior compressed ridge.
