Head and thorax finely, closely punctured ; the abdomen almost as 
strongly, but not so closely punctured ; the apex of the scutellum is 
smooth. This species is very like D. alaris Saus. The two may be 
separated thus : — 
The hair on the head and top of thorax fuscous, on the sides of the apical four abdominal 
segments white ; a reddish spot on the eye incision ; pygidium red Heterotrichia. 
The hair entirely black, eye incision immaculate, pygidium black. Alaris Saus. 
Discolia alaris Saus.

Black ; the head, body, and legs densely covered with white 
pubescence ; the third and following joints of the antennae red ; the 
eye incision almost entirely, the mark prolonged shortly above and longer 
below along the outer edges, the mandibles broadly in the middle, and a 
narrow line on the outer orbits, yellowish-orange ; wings fuscous viola- 
ceous. Male. 
Length, 9-12 mm.

Upper part of the head sparsely, weakly punctured, the clypeus 
sparsely and much more strongly punctured. Pro- and mesonotum and 
the scutellum rather strongly and closely punctured, but with the punctures 
clearly separated ; the centre of the scutellums narrowly smooth ; the 
metanotum more closely and less strongly punctured, more sparsely at 
the central furrows. The calcaria are blackish, the tarsal spines white. 
Looks like a small form of D. ruficornis F., but may be readily known 
by the hair being white instead of black.
