PJILEBOTOMUS. 215 



bristly pale grey recumbent hairs, which are more yellowish 

 towards the tip of the abdomen. Genitalia of male with the upper 

 appendages having the distal joint less than half as long as the 

 proximal one, bearing four chaetae, each as long as the joint : one 

 pair is situated at the tip of the appendage and the other a short 

 distance nearer the base of the joint ; intermediate appendages 

 without a ventral branch ; the dorsal branch resembling that of 

 P. perturlans; lower appendages slender, cylindrical, slightly 

 shorter than the basal joint of the upper palir, bearing at the 

 tip (in addition to a bunch of fine bristles) seven minute, conical 

 chitinous spines. Intromittent organ long and slender ; the 

 apices of the valves club-shaped; genital filaments well developed. 

 The female genital organs much as in P. perturlans. Legs with 

 coucolorous pubescence ; coxa? and trochanters pale brown ; the 

 basal part of the femora distinctly lighter than the apical, the 

 contrast apparently more marked in the female, though, owing to 

 paucity of material, this may be individual variation only. Hind leg 

 one and a half times as long as thorax and abdomen together; the 

 femur nearly three-quarters the length of the tibia, and once and 

 two-thirds that of the metatarsus, which is three-quarters that of 

 the remaining joints together. Wings pointed; 1st longitudinal 

 vein ending at three-fourths of the wing; fork of 2nd vein 

 slightly before that of 4th vein, both distinctly before middle of 

 wing ; petiole of 1st submarginal cell very short.

Travancore, S. India, below the western slopes of the Western 

 Ghats, in jungle, numerous specimens being taken "at light" by 

 Dr. Annandale, at Nedumangad, Pallode, and Maddathorai, in 

 November 1908. 



Types in the Indian Museum. 



Very near P. perturlans; distinguished by a different venation, 

 shorter legs, and better developed chaetse in the male genitalia.

<3 $ . Body uniformly brown, with concolorous bristly hairs, 

 paler in the female than in the male; coxae yellowish, remainder of 

 legs silvery grey. Wings pale brownish grey. 



Abdomen : the genitalia of the male with the " distal joint of the 

 upper appendages slightly shorter, and much more slender than 

 the proximal joint; its outlines are somewhat sinuous, and it 

 bears five long, stout, curved, sharp chaetae, which are arranged 

 as follows : a pair at the tip of the appendage, a pair on the 

 outer margin at about half the length of the joint, and a single 

 chaeta on the inner margin nearer the base. The ch setae are 

 equal or subequal. The intermediate appendage (morphologically 

 the lower branch of the upper one) is slender, pointed, and turned 

 upwards at the tip. It bears a minute, pointed, naked lobe on 

 its ventral surface, and a similar one on its external lateral
