IÇIS-] M. Bkzzi : Indian Trypaneids (Fruit-Flies). loi 



Head white, the frontal band tawny ; the upper part of the occiput from the 

 vertex to the neck is black ; a large brown spot on the cheeks under the eyes ; 

 antennae yellow; palpi whitish, darkened at the base, with some short black bristles; 

 proboscis brownish; all the bristles are black; frons with a few short dark hairs, the 

 swollen part of the occiput with longer white hairs ; some very short black bristles 

 on the upper posterior margin of the eyes. 



Thorax wholly black, shining, with a short yellowish pubescence on the back ; 

 the following markings white: the humeral callosities, the whole mesopleura, the 

 fore half of the pteropleura (all these three spots being united to form a very large 

 oblique patch), a large spot on each side of the metanotum including the hypopleura. 

 Scutellum white, shining, with a very narrow black band at the base and three 

 black spots on the hind margin, one apical between the insertion of the two apical 

 bristles, the others lateral beginning just beneath the insertion of each basal bristle. 

 All the white parts are wax-like and shining. All the bristles are black ; there are 

 some white hairs on the propleura, on the white part of the pteropleura, and in the 

 lower portion of the sternopleura. Haltères and squamae white, with white cilia. 



Abdomen black, the first segment sometimes yellowish; the white bands are 

 broad and equal, occupying the whole of the second and of the fourth segments; the 

 dorsal surface is short-haired ; at the base the hairs are somewhat longer and are black 

 on the black parts and white on the white parts. Genitalia of the male black, a little 

 prominent; the black bristles of the fifth segment are long and strong, 5-7 in number. 

 The ovipositor is shining black, not depressed, with very short black hairs; I cannot 

 perceive any trace of bristles on the fifth or on the sixth segment of the female 

 abdomen. 



Legs yellow, the coxae also; the four posterior femora darkened at the end, the 

 intermediate almost wholly black; fore femora sometimes also darkened above, the 

 bristles of the underside 5-6 in number ; the hind femora at the end show some black 

 bristles. 



Wings whitish- hyaline, with the following brown markings: (i) A spot a little 

 beneath the base, beginning at the fore border and showing some small streaks on 

 the basal cells; the anal cell hyaline, its upper fold chitinised black, as in Ceratitis ; 

 the stigma brown in the basal portion, yellowish white in the apical, (ii) A broad, 

 oblique cross-band which extends from beyond the apex of the first vein to the pos- 

 terior margin beyond the apex of the sixth vein, reaching along the small -cross- vein 

 and at the costa united with a broad stripe that extends along the costa to midway 

 between the apices of the third and fourth veins, filling the costal margin to the third 

 vein ; in this band near the costa are 4-5 brown dots, (iii) A large border on the pos- 

 terior cross-vein, which begins on the fourth vein and reaches the posterior margin, 

 where it is widened, (iv) An oblique streak beginning at the third vein just in the 

 middle between the small cross- vein and the tip, and reaching the posterior margin 

 a little beyond the tip of the fourth vein. This streak is sometimes united across 

 the fourth vein with the band on the posterior cross- vein, forming a V-shaped rivulet.
