Idlopygus. This necessitates a cliaiigc of name foi' Idiopyrjus 

 trochanteratus, Mallocli, described in Part III. of this series 

 o!" papers. I therefore propose to substitute the name u/undi 

 for the species. 



Stein's species is very closely allied to mine, but whether 

 or not it is the same, or is hirtiventris, Mallocli, it is 

 impossible to say without a careful examination of the ty])e, 

 which was, according to Stein, in poor condition. The legs 

 of both my species are black, while in ti^ o chanter atus^ Stein, 

 the tibife are slightly reddish. 



Stein's species came from Kilimandjaro, German East 

 Africa, the others are also from East Africa. I have seen 

 no species of the genus from the western part of that 

 coutiueiit. 



Eulimnophora trimaculata (Stein). 



I have before me a male of this very striking species from 

 the top of the Aberdare Mts., 9500 feet, 28. ii. 1911 

 (7". J. Anderson). 



The fourth vein of the wing is very noticeably curved 

 forward apically, the thorax has three black spots on the 

 anterior margin, contiguous in front, only the median 

 one extending to suture, and there are three contiguous 

 })lack spots behind the suture ; the sides of the abdominal 

 tergites 1 and 2 are broadly yellowish, and the large sub- 

 triangular black spots form two almost entire submediau 

 vittfc on the al)domen. 



A slightly aberrant species, but quite evidently belonging 

 to this genus. 



Genus Rhynchomyd^a, nov. 



Generic characters. — Similar to Cyrtoneura in general 

 liabitus. Eyes of male subcontiguous, of female separated by 

 a little less than one-third of the head-width, bare in both 

 sexes; orbits of male with very fine short hairs, of female 

 with bristles as in Helina, but only the upper one directed 

 backward ; arista long-plumose; face with a very conspicuous 

 rounded ridge vertically in middle or tuberculate. Thorax 

 with the dorso-centrals, except the posterior two pairs, very 

 short, pteropleura hairy, piosternura hairy, hairs descending 

 on sides of scutellum. Third wing-vein setulose at base, 

 fourth curved forward apically.
