«tout, the lobes at the dorsal angles narrowly oval, concave 

 mesiallj, sparsely setose, and with the broadly-rounded tips 

 nearly approximate. Type Cecid, 1807. 



Heterobremia 11. g. 



The peculiar type placed here is easily distinguished from 

 Homobremia by the two widely separated linear processes 

 •extending from the posterior lateral angles of the ventral 

 plate and reaching to the tip of the style. The genitalia 

 are very complex, and there are also marked structural 

 peculiarities in the antennas. Type H. f areata n. sp. 



Heterobremia furcata n. sp. 



The peculiar midge described below was labelled "Lonji, 

 Cameroon, West Afx'ica, near the Ulou River." This locality 

 is about fifty miles north of Kribi. The midges were recorded 

 ■as resting in great numbers on spider webs in the trunk 

 •of a hollow tree, and were associated with Homobremia 

 -agilis described below. The type is deposited in the New 

 York State Museum, Albany, N.Y., U.S.A. 



Male. — Length TS mm. Antennas ^ longer than the 

 body, thickly haired, dark brown, 14 segments, the 3rd and 

 4th fused, the 5th with stems as long and 2^- times their 

 ■diameters respectively. Basal enlargement subglobose, with 

 a sparse basal whorl of long, stout setaj and a subapical 

 ■circumfilum, one bow being greatly produced, the distal 

 enlargement with a length about ^ greater than its diameter, 

 a subbasal, low circumfilum peculiar on account of its dis- 

 tinctly oblique course around the segment, a thick whorl of 

 moderately long, strongly curved set^e near the middle, a 

 subapical whorl of long, stout setfe, an apical and well- 

 developed circumfilum, the latter with at least one greatly 

 produced bow. Terminal segment, basal portion of the stem 

 with a length nearly 3 times its diameter, the distal 

 •enlargement with a length over twice its diameter, somewhat 

 •swollen apically, and with a slender, fusiform appendage,
