102 N. ANNANDAI.E : A New Phlebotomus. [Voi^, II, 



Legs ver}' long, the hinder most being about three times as long 

 as the thorax and abdomen together ; femora much shorter than 

 tibi« ; metatarsi in all cases at least as long as the remaining joints 

 of the tarsi together ; legs gre}' with very strong reflections, which 

 make the tibiae and tarsi appear silvery white in certain lights ; 

 femora bearing fine hairs and bristles similar to those on the abdo- 

 men but finer, also flattened spatulate scales ; tibi^ and tarsi 

 covered with angularly- bent scales and bearing, especially at the 

 joints, stifY straight, slender hairs. 



Wing of P/i. ayoentipes denuded of hairs and scales. 



Wings ' narrow, obtusely pointed at the tip, iridescent, silvery 

 grey with a hoary fringe on the posterior border, immaculate. The 

 fourth vein joins the third some distance in front of the apex of 

 the upper anal ceh and almost on a level with the bifurcation of 

 the sixth vein. Ninth vein obsolete, indistinguishable from the 

 anal furrow. Upper anal cell long and narrow ; lower anal cell in- 

 complete, its apex a considerable distance behind that of the upper 

 cell. Cell formed by junction of first and second veins very long 

 and narrow. Scales at base of wing only ; halteres covered with 

 scales. 



Genital apparatus of the male conspicuous ; the superior ap- 

 pendages long and stout, their distal joint bearing five long, stout, 

 broadly arched, sickle-shaped chsetse, viz., a single chseta about a 

 third of the distance between the two ends of the joints from its 

 base, a pair of slightly unequal chtetse near the middle of the joint, 

 and a terminal equal pair ; the ventral surface of the basal joint 

 deeply grooved and provided with a row of stift' hairs ; inferior 

 appendages long and rather slender, bearing a large bunch of stout 

 bristles at the tip. 



Ph. argcntipes occurs not uncommonly in Calcutta, especially 

 during the winter months. It is nocturnal in its habits and is 

 often found in the basements of houses. Possil^ly it is identical 

 with the species figured recently by xMaxwell-Lefroy,^ but its legs 

 appear to be longer. The palpi of the species figured by Giles ■■ 



I The numbering of the veins follows the diagram pubhshed by E)aton in 1893 

 [Ent. Mon. Mag. (2),"iv, p. 7). It has seemed be.st to use numbers for the_ veins 

 rather than names. Schiner numbers the veins differently, but the venation of 

 our species agrees with his description precisely.
