﻿TABAN1DAE— FART I. 119 



of each postalar callus, and a pair of admedian tufts in front of scutellum on 

 hind margin of main portion of dorsum, unconnected with each other or with fringes 

 on postalar colli ; dorsum elsewhere clothed with short black hair, pleurae and 

 pectus clothed with longer black hair. Abdomen : dorsum of second segment 

 with a large patch of appressed, bright chrome-yellow hair on each side, not 

 quite reaching lateral margin ; dorsum of fourth segment with a very small 

 median tuft of chrome-yellow hairs on hind border ; posterior angles of dorsal 

 scute of fifth segment tawny-ochraceous and clothed with similarly coloured hair ; 

 tawny-ochraceous area at distal extremity clothed with similarly coloured hair, 

 sixth segment black at base, then tawny-ochraceous, seventh segment entirely 

 tawny-ochraceous ; ventral scute of second segment with a small patch of 

 appressed, Naples-yellow hair on each side ; ventral scute of fifth segment with 

 some tawny-ochraceous hairs near hind border, dorsal scute of same segment 

 with a few similar hairs towards hind border ; abdomen except as stated clothed 

 with minute, appressed, black hairs. Wings : costa (except extreme base, which 

 is darker) and first longitudinal vein ochraceous, remaining veins in yellow 

 portion ochre-yellow. Squamae cream-bufF. Halter es : knobs ochraceous-buff, 

 stalks dark-brown. Legs : coxae clove-brown or black, clothed with black hair ; 

 femora (middle legs missing in case of type) cinnamon-rufous ; front tibiae and 

 tarsi ochraceous-rufous, hind tibiae and tarsi tawny-ochraceous or ochraceous. 



Transvaal : Natal border, near Newcastle (W. L. Distant). 



This handsome species, which is named in honour of its discoverer, in general 

 appearance presents resemblances to C. chrysopila, Macq., and C. chry so stigma, 

 Wied., from both of which, however, it is distinguished inter alia by the spots or 

 tufts of chrome-yellow hair on the dorsum of the thorax all being separate, 

 instead of the tuft in the presutural depression being connected with that on the 

 humeral callus on each side, and the spots on the hind border being each 

 continuous with the fringe on the postalar callus on the same side. From both 

 the species mentioned C. distanti is further distinguishable by the abdomen 

 (ventral and dorsal surfaces) being differently or less extensively spotted with 

 patches of yellow hair. 



Cadicera obscura, Eic. 



Corizoneura obscura, Ricardo, Ann. Mag. Nat. Hist. ser. 8, vol. i, p. 56 (1908). 



Owing to a combination of characters (namely, the shape of the face, and the 

 size and position of the terminal joints of the palpi, which, although pointed at 

 the tips, are large and raised above the proboscis, instead of small, and situate 

 alongside or closely approximate to the base of the latter), it would seem 

 advisable to transfer this species to the genus Cadicera. With the two new 

 species described below, C. obscura forms a group characterised by having the 

 abdomen narrower than in the more typical forms, and the first posterior cell in 

 the wings either more or less narrowly open, or else closed on or immediately 

 before the hind margin, instead of closed some distance before reaching the latter, 

 and consequently pedunculate. 



The type of Cadicera obscura, obtained at Blantyre, Nyasaland Protectorate 

 in November, 1904, by Dr. J. E. S. Old, is the only specimen of this species yet 

 received by the British Museum (Natural History).
