ENTOMOLOGY 885 
So far as can be judged at present, Stenophara appears to have much the 
same distribution as Philoliche, being likewise strictly Ethiopian. In the Bel- 
gian Congo it is represented by one species. 
Stenophara rodhaini (J. Bequaert) 
Pangonius rodhaini J. Bequaert, 1924, Rev. Zool. Afric., XII, 4, p. 462 ( 2; Luki, Belgian Congo). 
This species is known only from the type locality in the Lower Congo. 
Female. — Head and thorax black; the dorsum dark pollinose, with lighter markings faintly 
indicated anteriorly and on the sides. Abdomen smoky yellowish brown on the first three seg- 
ments, passing into blackish brown posteriorly; the ventral side paler yellowish brown; second, 
fourth, and fifth tergites with narrow white apical fringes which broaden into spots in the hind 
corners. Antennae, palpi and legs dark chestnut-brown to black, with black hair. Face without 
shiny callosities; beard white. Proboscis not much longer than the height of the head (3 mm.), 
bluntly ending in large labella. Wings fairly uniformly and strongly smoky brown throughout. 
Length, 12 to 14.5 mm. 
Male unknown.

This Ethiopian genus appears to be strictly East African, the seven species 
known at present to belong here being found in Abyssinia, Kenya Colony, Nyasa- 
land, Southern and Northern Rhodesia and the Katanga District of the Belgian 
Congo. 
The three species of the Congo may be separated by the following key: 
1. Male and female: Smaller, 11 to 14.5 mm. long. Dorsum of thorax dark olive-yellow 
pollinose. First three segments of abdomen bright ochraceous, the remainder black 
with lighter hind borders. The second segment with a median black spot on the 
anterior margin. Hind margins of second and following segments with transverse 
bands of pale shiny hair, silvery-white anteriorly, more yellowish behind. Wings 
tinged with luteous (more brownish in the subspecies centralis, which does not reach

Averaging larger, 13 to 16.5 mm. long. Dorsum of thorax dark olive-brown, grayish 
pollinose. Abdomen black above; the hind margins of first, second, and third seg- 
ments with broad bands of pale pubescence, which also covers the hind margins or 
whole of the fourth and following segments. Wings light mummy-brown, darker

This species has been taken at Bukama and Sankisia in the Katanga. In 
March 1911, both sexes were observed at Bukama visiting the flowers of Borreria
