TWO NEW SPECIES OF AFRICAN FRUIT-FLIES. IT 



Although the British Museum collection as yet contains no specimen o£ 

 Trypeta grata, Wied., judging from Loew's description of the species and 

 figure of the wing, referred to above, there can be little doubt that this specie* 

 also belongs to Carpophtlioromyia. The scutellum is said to have " three 

 large, quadrate, shining black spots," visible from above, on its posterior margin 

 (C tritea, Walk., has three clove-brown spots on the posterior margin of the 

 scutellum, but these are not visible from above) ; the clove-brown or black 

 costal border sends off a branch towards the tip of the wing, as in C, pidcJiellay 

 Austen, but the marking on the basal half of the wing is different, and the 

 band covering the posterior transverse vein is almost triangular (" wedge- 

 shaped," apiid Loew, loc. cit., p. 268), being broader on the posterior margin 

 of the wing. As stated in the foregoing table, the humeral calli are yellow,. 

 and this character alone will serve to distinguish the species from C. tritea,. 

 Walk., in which the marking of the scutellum is somewhat similar, but the 

 humeral calli are dark brown.
