82 REI'OUT ON ECONOMIC ENTOMOLOGY 



a fow lint 8calus on tlic latunil lobus left iiiid a IfW at tlio base of thu iiiiil lulio, if tlu'se are in 

 their normal position tlic species must form the type of a new genus. As there were some 

 other detached scales on the scutellum, clearly head scales, it may be that the flat ones are 

 also stray ones from another part of the body. 



The species is very marked, but the exact generic position must be left pro lem. 



Dr. Halfour, who sent the specimen, pointeil out that there were bluish-purple and 

 green scales laterally on the abdomen. I eouM not detect these, probably owing to 

 fading after death.

itdcomyia This (juaint iEdinc was taken some years ago by Dr. Loat on a snu\ll lake eight miles

It lias since been taken by {lolonel IViitoii, I'.iM.U., on the Jur river, a tributary of the 

 Bahr-El-Ghazal, in November. 



This .^dine can In told at onre by tlie Mansonia-likc wing scales. 



The thorax is brown, witii scattered creamy scales, which become white at the 

 sides and behind ; the scutellum is ochreous with black scales on the side lobes, ochreous 

 ones on the mid lobe. 



The brownish alidoiiuii has two patches of cicaiiiy scales on the apices and two patches 

 of white scales on tlic base of tlie segments, the apical segments are often all yellow sealed. 

 The legs are mottled ami banded with creamy, purple and white scales, the apices of the 

 mid femora having dense tufts of dark scales. 



The wings have mottled yellow and deep purple-brown scales with normally three white 

 costal patches, the two mi<Idle ones forming two bands going partly across the wings, the 

 apical one also continues as a broken banil around the end of the wing, and there is also 

 a pale patch between each band in the middle of the wing field. 



The length varies from 35 in the male to 4"5 in the female. 



Dr. l^alfour points out that the specimen taken by Colonel Pcnton has four silvery 

 white wing spots, and the dense femoral tufts project forward anteriorly. 



This insect occurs in South and Central America, West Indies, India, and Malay, and 

 I expect Skuses' ^Udes venuxtipes from near Sydney is the same insect. 



It seems to inhabit houses and open country indiscriminately and bites, but not as a 

 rule very severely.
