Tgi3-] M. Bkzzi : Indian Trypaneids (Frui^-Flies). 123 



Abdomen with black pubescence and black bristles ; venter yellowish ; 5th seg- 

 ment black with yellow tip in both sexes, 6th in the female wholly yellow. Ovipositor 

 yellowish, black at the base on each side. Genitaha of the male round, prominent, 

 reddish brown, shining, pale-haired ; the pendulous middle organ is light yellow with 

 a pale fringe ; on the middle of the venter are two prominent approximate yellow 

 lamellae, provided with black bristles. The dark portions of the legs are reddish 

 brown ; front femora in both sexes with only 3-4 bristles beneath. 



Wing-pattern as described by Wiedemann : the brownish cross-bands are in- 

 terrupted by clearer streaks, that of the middle band is between the 4th and 5th veins, 

 and those of the apical band between 2nd and 3rd and 3rd and 4th, this last the broader. 

 The stigma is brownish, with the extreme superior apical angle pale ; the posterior 

 cross- vein is margined interiorly with fuscous and exteriorly with cinereous. 



Some specimens of both sexes from Calcutta, April 3rd. 1903. 



31. Staurella dissoluta, n. sp. cc ?. 

 (PI. ix, fig. 34.) 



Very like the preceding, but easil}^ distinguished by the darker and un variegated 

 pattern of the wings and by the crossed apical band being divided into two. I^ength 

 7 — 8 mm., with the ovipositor. 



The body is a little more robust than in the preceding and the abdomen is more 

 darkened ; the male genitalia are exactly of the same shape but the lower lamellae 

 are blackish. The principal difference is shown by the pattern of the wings, which is 

 much darker and not variegated by lighter portions ; the small band on the humeral 

 cross- vein is a Httle broader ; the /\-shaped middle band has the same appearance, 

 the greater branch being narrowly interrupted just above the fifth vein. At the tip 

 are two cross-bands, one on the posterior cross- vein, extending from the hind margin 

 to the third vein ; the other is broader, beginning at the fore border before the tip of 

 the second vein and ending at the hind border after the end of the fourth vein ; on 

 the fore border a little beyond the stigma, is a brown spot, which reaches below the 

 second vein, and sometimes the third. The border of the posterior cross- vein is only 

 blackish, without lighter margin.

. 32. Staurella nigripeda, n. sp. 9 . 



(PI. ix, fig. 35-) 



Easily distinguished from the two preceding species by the black colouring of 

 the body and legs, and by the different pattern of the wings. Length 7 mm., with the 

 ovipositor. 



Occiput shining black, with a yellow spot on the sides and a ferruginous spot 

 at the vertex : f rons in the middle blackish , yellowish on the sides and in front of the 

 antennae ; face dark, with grey pollen ; cheeks yellowish. All the bristles are black, 

 the superior or. are not inserted upon a prominent tubercle : or entirely wanting
