AET. 2 THREE NEW SPECIES OF TWO-WINGED FLIES ALDRICH 6 



Abdomen black with mixed black and yellow appressed scales. On 

 the first segment there are dense long, erect, scaly hairs at the sides, 

 continuing in a thin and reduced series across the middle. The 

 second segment shows a few paler scales across the base, hardly 

 enough to call crossbands ; the following segments show scarcely any 

 banding except the last three which when viewed from behind show 

 mostly black scales across the base. The sides of the abdomen are 

 fringed with large blunt, black scales, a few whitish. The venter is 

 covered with long, slender, yellow hairs not very dense. Legs cov- 

 ered with mixed light and dark scales. Pul villi wanting; hind femur 

 with a row of about seven bristles on the lower front edge. Wing 

 dark brown on basicostal half, brownish hyaline on the remainder, 

 the line of division not very distinct, running obliquely from the mid- 

 dle of the axillary cell to the costa just before the apex. All the 

 forks and crossveins bear spots and there is a slight trace of addi- 

 tional infuscation along the anterior fork of the second vein near its 

 tip, a less distinct trace on the posterior fork of the same and a slight 

 spot in the open apex of the anal cell. 



Length, 4.6 and 4.8 mm. 



Described from two females, Shillong, India. 



Type.— Female, Cat. No. 40303, U.S.N.M. 



This species is close to Exoprosopa msuluta Walker, but ac- 

 cording to the descriptions of Brunetti and Nurse E, sipho differs 

 in having a much longer proboscis, the dense bristly hairs of the 

 pleura confined to the upper edge, the abdomen with very indis- 

 tinct bands and with well-developed scales along the edges, and 

 the venter covered with pale hairs. In the paratype specimen 

 the proboscis would, if directed forward, extend a little beyond 

 the antennae, but in the type the organ is lengthened out as if by 

 the straightening of an elbow so that it is about as long as the whole 

 body not counting the head; or as it projects downward from the 

 head its length is equal to about two and a half times the vertical 

 diameter of the head. The paratype specimen will be deposited 

 in the British Museum.
