hypopleural spot. Scutellum like the thorax, with four bristles, the basal pair 

 weaker. All the bristles are black. Metanotum with two brown spots on the sides. 

 Haltères pale yellow. 



Abdomen narrow and elongated, clothed with white rather long pubescence ; 

 that of the male without lateral bristles on the third segment. It is, like the thorax, 

 entirely ferruginous ; the first segment is yellowish at the base and the second at the 

 apex; third segment with a basal black cross band, broadly interrupted in the 

 middle; a longitudinal black stripe runs from the middle of the third segment to 

 the end of the abdomen. Belly yellow, with black quadrate spots in the middle of 

 the segments. Ovipositor very short, reddish. 



I^egs entirely yellow, all the femora below with a shining broad black stripe, that 

 of the hind femora being smaller and apical ; hind tibiae darkened ; first two segments 

 of the tarsi whitish. 



Wings as in caudatus , but the brown costal border less widened at the end, and 

 the anal stripe in the male not broadened at the tip. 



Some specimens from Peradeniya, Ceylon (Gr^é?;^), obtained through the kind- 

 ness of Prof. Petri of Rome, bred from Garcinia fruits, viii-og : types cf and ? in the 

 Indian Museum. 



8. Bactrocera scutellaris, n. sp. j , ? . 

 (PI. viii, fig. 10). 



A medium-sized species, easily distinguished from any other by its predominat- 

 ing black colouring, by the scutellum being largely black at the tip and bearing four 

 bristles, and by the black ovipositor of the female. Length 6-8 mm. 



Head yellow, the face and the occiput shining; the frons opaque but shining on 

 the vertex and narrowly near the orbits; facial spots triangular, with the inner 

 corners a little approaching together in the middle of the face ; a brown spot in the 

 middle of each cheek quite near the lower corner of the eyes ; frons marked with a 

 brown spot in front of its centre and with three pairs of lateral brown dots ; vertex 

 with a transverse black band including the ocelli; occiput wholly black, with a 

 narrow complete yellow circle around the eyes; antennae yellow, the third joint 

 darkened at the tip; arista yellow at the base; palpi yellow, quite bare, with some 

 hairs on the underside only; proboscis yellow mottled with brown, with some pale 

 hairs; frons with short hairs, cheek and lower portion of the occiput with rather 

 longer hairs; all the bristles are black, i genal, i fron to-orbital, 3 lower fronto- 

 orbital, of which the 2 apical pairs are approximated together, and 2 vertical; a tuft 

 of yellowish short bristles at the middle of occiput on the callus over the insertion 

 of the neck. 



Thorax and abdomen densely punctate, covered with a short pale pubescence. 

 Thorax quite black , both on the sides and below ; the following markings yellow : 

 three very small longitudinal streaks on the back behind the suture (a shorter one 

 in the centre, the others on the sides above the wings), the humeral callosities, a 

 fascia on the mesopleura extending from the transverse suture of the back to the 

 upper part of the sternopleura, a large spot on each side of the metanotum inclurl-
