So far, at any rate, as may be judged from the male, 

 Dorcaloemus bicolor, owing to its coloration and narrow and 

 elongate body, is readily distinguishable from any other 

 species of its genus at present described. 



Genus Pangonia, Macq. 



Pangonia bubsequa, sp. n. 



? . — Length (2 specimens) 16 to 17*2 mm. ; width of 

 head 5*2 to 5 '8 mm. ; width of front at vertex just under 

 1 mm. ; distance from upper margin of occiput to anterior 

 extremity of face 4*4 to 46 mm. ; length of proboscis 7'2 to 

 9 mm. ; length of wing 14 to 16*4 mm. ; greatest width of 

 wing 5 to 5 - 6 mm. 



Allied to Pangonia oldii, Austen, from which it may be 

 distinguished by the tawny-ochraceous area on the dorsum of 

 the abdomen being confined to the first (i. e. first visible) seg- 

 ment, which contrasts sharply with the following segments in 

 colour, and by the absence of a {more or less complete) trans- 

 verse band of silvery-white hair on the hind borders of the 

 second and fourth abdominal segments. — Thorax olive-broivn, 

 dorsum when viewed at a low angle from behind appearing dull 

 saffron-yellow pollinose ; first {visible) segment of abdomen 

 tawny-ochraceous, second segment dark mummy -brown, third 

 to sixth segments inclusive clove-brown, sixth and seventh 

 segments yellowish pollinose. and clothed with Naples-yellow 

 hair, lateral margins of fourth and fifth segments and hind 

 border of fifth segment (more or less completely) clothed with
