iQio.) N. Annandale : Species of Phlebotomus 49 



joint of the superior appendage, bearing at its tip (in addition to a 

 bunch of fine bristles) seven minute, conical, chitinous spines. 

 Intermediate appendage without a ventral branch; the dorsal 

 branch resembling that o' P. pcrtiirhaus. Superior appendage with 

 the distal joint less than half as long as the proximal one, bearing 

 four chaetae, each of which is as long as the joint; one pair of 

 chaetse is situated at the tip of the appendage and the other a 

 short distance nearer the base of the joint. Intromittent organ 

 long and slender ; the apices of the valves club-shaped ; genital 

 filaments well developed. 



This species is closely related to P. pertiirbans, the place of 

 which it takes in the jungles at the base of the Western Ghats in 

 Travancore, where I took numerous specimens at light in Novem- 

 ber, 1908. The anterior branch of the second longitudinal vein, 

 however, is much longer than it. is in P. perturhans and the legs are 

 shorter, w^hile the chsetse of the male genitalia are much better 

 developed. 



Distnhufion. — Travancore_, S. India, below the western slopes 

 of the Western Ghats. I took specimens at Nedumangad, Pallode 

 and Maddathorai in November.

P- 559, fig- 358 (1909)- 



Size and proportions. — Total length 2-5 mm. Length of wing 

 175 mm., greatest breadth of wing 0-25 mm. Hind leg rather 

 less than twice as long as the thorax and abdomen ; the femur 

 slightly shorter than the tibia , which is more than twice as long as 

 the first joint of the tarsus; the first joint of the tarsus less than 

 half as long as the femur, shorter than the remaining joints 

 together by half of its own length. 



Colour. — Silvery grey ; the fringes on the wings, the thorax 

 and abdomen appear in certain lights to be darker than the wings 

 themselves and the limbs: the usual silvery lights present. 



Head. — Rostrum prominent, somewhat arched. Antenna? 

 with the second joint of the scape bearing several rows of flat 

 scales; the joints of the flagellum normal. Palpi with four joints; 

 the first three subequal, short ; the fourth nearly as long as these 

 three together. 



Thorax less tumid above than in P. argentipcs. 



Abdomen rather short, clothed in close-set u])riglit hairs of 

 different lengths and with a dense fringe of upwardly curved hairs 

 running along each side of the abdomen near the ventral surface. 



Wings narrow, pointed, the jiosterior border hardly more 

 strongly arched than the anterior, the third longitudinal vein 

 dividing the wing into two nearly equal and similar halves. The 

 anterior branch of the second vein not much shorter than the 

 second branch, shorter than the distance l)ctwcen the two forks of
