East Africa. The several species of this quite cosmopolitan genus 
are extremely similar, and as they are attracted to and probably 
breed in old cheese, meat and other animal products, some have 
undoubtedly been widely spread by commerce particularly in 
the tropics. 
To the original description of the female the following 
may be added from the well preserved specimens sent by Dr. 
Munro. There are four large divergent supra-antennal bristles, 
each longer than the diameter of the antenna; the lower pair 
are proclinate, the upper pair erect or slightly proclinate, set 
farther apart than the lower ones; above these are ten other 
bristles, one on each side of the front midway between the upper 
post-antennals and the eye, a median pair just below the ocelli, 
an ocellar row of six. The thorax bears six bristles, one at each 
anterior angle, one at each posterior angle and two very widely 
separated ones along the posterior margin. Pleura just below 
the posterior lateral bristle of the mesonotum with a very large 
bristle that projects laterally. In addition the head, thorax, 
abdominal plates and legs are rather densely clothed with fine 
black hairs. 
Male. Considerably larger than the female, 1.7-1. 8 mm. in 
length; wings large, approximately as long as the body. Head 
pale brownish, darker between the ocelli; thorax pale brown 
above, ochre yellow below; abdomen piceous above, whitish 
below, the hypopygium piceous, with brownish ventral lamella 
and pale dorsal one. Front with four supra-antennal bristles: 
the lower pair close together and clearly proclinate; the upper 
pair twice as far apart, strongly divergent and nearly porrect; 
above these there are 12 other bristles, a pair slightly above the 
post-antennals on each side of the front of which the lateral 
bristle is close to the eye and above the inner one, a pair just below ■ 
the ocelli, and six forming a series of three pairs on the vertex 
above the ocelli. Post-ocular cilia much enlarged; cheek with 
a series of conspicuous forwardly directed bristles forming a line 
parallel with the lower eye-margin; palpus with about six mod- 
erate bristles; proboscis projecting, obtusely pointed, more 
slender than in the female. Third joint of antenna broadly
