230 PROF. M. BEZZI. 



bristles are black; oc. long and strong; only two i. or., with a very thin and rudi- 

 mentary one in front of the 2nd pair ; pvt. long ; genal bristle very strong. Back 

 of thorax reddish, with yellowish pubescence ; the black lateral spots are about as 

 in striata and likewise shining above and velvety opaque below, but the middle 

 longitudinal stripe is faintly indicated by a very narrow, dark brown line, and there 

 is no black patch behind the suture ; the pleurae are uniformly pale yellowish, 

 immaculate ; there is a double, whitish hypopleural spot ; the mesophragma is 

 shining reddish, and the postscutellum is black. The scutellum bears three very 

 broad, shining black spots, the middle one extending above only to the middle of the 

 disc, the lateral ones reaching the base ; besides there is on each side a deep black, 

 velvety opaque, rounded spot on the postalar calli, invading also the extreme sides 

 of lateral margin of scutellum. Chaetotaxy complete, with strong and black bristles, 

 the dc. are placed a little before the line of the a. sa. ; scp. well developed ; 2 mpl. ; 

 pt. very strong ; 4 set. Halteres pale yellowish, with a darker knob. Abdomen 

 elongate, reddish, with pale yellowish base ; hind border of 1st and almost the 

 whole of 3rd segment with broad, complete, transverse bands of whitish dust. 

 Ovipositor long, reddish brown, with short black hairs. Sides and end of abdomen 

 with long black bristles ; venter yellowish, with whitish dust. Coxae and legs 

 entirelv pale yellowish, the tarsi being a little darkened at the end ; bristles black : 

 hind tibiae without distinct row. Wings with strong costal bristle and normal 

 neuration ; the hind cross- vein however, which is rather perpendicular in striata, 

 is here oblique as in Ceralitis ; small cross- vein a little beyond the middle of the 

 discoidal cell. Base of wing to the end of the second basal cell with alternate 

 blackish and hyaline streaks, one dark streak in each cell, beginning with the costal 

 and ending with the anal cell ; a short perpendicular yellowish band extending 

 from base of stigma to the 5th vein ; stigma hyaline, with narrow yellow base. The 

 other bands are yellowish, infuscated towards the hind border and disposed in the 

 usual radiating form of Ceratitis ; the oblique band over the hind cross-vein is united 

 with the basal band in front of the small cross- vein ; the marginal band has three 

 fuscous spots along the costa, where it is narrowly colourless ; the subapical oblique 

 streak is complete and well united to the costal band. Along the 5th longitudinal 

 vein the basal complete band is narrowly united with that of the extreme base. 



Type ^ (British Museum), a single specimen from Anglo-Egyptian Sudan 

 (H. H. King). 



V. Ceratitis, MacLeay, 1829, s. str. 



As here restricted, the present genus is confined to the type species capitata, Wied., 

 from which C. catoiri, Guerin-Meneville (Rev. Zool., vi, 1843, p. 197), is possibly 

 distinct.* This latter species is recorded from the Island of Mauritius, and Froggatt 

 in 1911 noted it from the Seychelles ; capitata is known from the greater part of 

 A f iica. 



*[C. catoiri is certainly distinct from C. capitata, being an obviously larger insect, 

 almost equalling G. rosa, Karsch, in size. The oblique band over the hind cross-vein 

 unites with the broad median band along the 4th longitudinal vein, and the apical 

 section of this vein is crossed by an oblique fuscous spot. The stalk of the cephalic 

 appendage in the male is much longer, the spatula being white in colour, and subtriangular, 

 with the apex broadly truncate or slightly rounded ; whereas in C. capitata the spatula 

 is black and irregularly diamond -shaped. — Ed.]
