﻿210 SOPHIA L. M. SUMMERS— A NEW SPECIES OF PHLEBOTOMUS, ETC. 



incomplete) formed of at least six distinct segments, namely a small basis, 

 followed by two co-equal segments that together make up more than two-thirds 

 of the whole palp, and three short co-equal terminal segments, of which the first 

 (true fourth segment) i3 broadly expanded (ovate) and the tip of the last (true 

 sixth) is truncated ; the palps have some scales among the hairs, and their total 

 length is about one-third greater than that of the proboscis. Antennae in both 

 sexes longer than the whole body (free portion of proboscis excepted), formed of 

 the usual sixteen segments of which the first is truncate triangular, the second 

 globose and the third is much longer than any of the others. 



Legs of the usual form, in the hind pair the tibia (which, as in all the legs, is 

 the longest segment) is as long as the combined head and body. 



Wings. In the male the greatest length of the wing is three and a half times 

 its greatest breadth ; it is bluntly pointed and the hind border is not very much 

 more strongly arched than the front border. The length of the second marginal 

 cell is contained 2f times, and that of the third marginal cell 1| times in the 

 length of the wing. In the female the wings are decidedly broader, but the 

 relations of the veins are about the same. Halteres large and remarkably long. 



Abdomen. The male genitalia have the usual general form. In the superior 

 claspers the two segments are of nearly equal length, but the basal segment is 

 very much stouter than the distal segment, being of an unusual elongate triangular 

 shape. The slender terminal segment is armed with only four spines, of which one 

 is terminal, one is situated on a prominent ante-terminal tubercle of the dorsal 

 surface, one stands rather beyond the middle of the supero-lateral border, and 

 one arises from a prominence a short distance behind the middle of the ventral 

 border. All four spines are stout and claw-like ; the terminal one is the stoutest 

 and longest, being more than half the length of the segment that bears it. The 

 inferior claspers have the usual boomerang shape and are about twice the length 

 of the first segment of the superior claspers. At the tip there is a tuft of long 

 erect hairs. 



This species is distinguished from any with which I have been able to compare 

 it by the great length of the head (proboscis included) which in the female is half 

 that of the rest of the body. The details of the wing venation very closely 

 resemble those of P. malabaricus, Annandale. 



The drawings were done by Colonel Alcock, to whom my very best thanks are 

 due for his great help.
