{Published hy permission of tJie Trustees of tJie British Museum.) 



Family TRYFETID^. 

 Subfamily Dacin^e. 



Caefophtroeomyia*., gen. nov. 



Closely allied to Ceratitis, MacLeay^ and agreeing thereiuith in thoracic 

 c]i(jetotaxy'\ and, venation: differing in general facies of body ^ in shape of 

 scutellum, and in that of ovipositor, the first segment of ichich, instead of being 

 flattened and truncate triangular in shajye, is thickened and tubular , resembling 

 that of Urophora. 



Cephalic bristles and shape o£ antennce as in Ceratitis ; arista plumose or 

 pubescent ; body in all species at present known for the most part shining 

 black, with yellow or yellowish-white markings on the pleur?e ; dorsum ot' 

 thorax frequently wdth characteristic transverse band or bands of minute, 

 appressed; whitish or yellowish hairs ; scutellum, — which in the known species 

 is entirely or mainly yellow or yellowish wdiite, — not rounded and swollen as 

 in Ceratitis, and in no way trilobate in appearance, but bluntly triangular, 

 and flattened on the sides. Wiiigs in at least one species speckled with 

 blackish brown near the base, as in Ceratitis ; costal spine present and 

 distinct ; first and third longitudinal veins setigerous. 



Typical species Jiw^ca vittata, Fabr. (Ent. Syst., iv. 1794, p. 355: — Trypeta 

 vittata, Loew, Berl. Ent. Z., v. Jahrg., 1861, p. 262, Tab. ii, fig. 3, — figure of 

 wing), which, originally met with in Guinea, is represented in the Museum 

 Collection by a male from Delagoa Bay, Portuguese East Africa (Mrs. Mon~ 

 teiro), and a male and female from Malvern, Natal, March and June, 1897 

 (6r. A, K. Marshall). It may be noted that, so long ago as 1862, it was 

 pointed out by Loew (Berl. Ent. Z., vi. Jahrg., p. 90) that this species belongs 

 to the DACiNiE. In addition to Musca vittata, Fabr., and the two new species 

 described below, Trypeta graia, Wied. (Auss. Zw. Ins., ii. 1830, p. 498 ; Loew, 



* Kap7ro-(f)d6pos, spoiling fruit ; fivla, a fly.
