rgio.] N. Annandale : Species of Phlebotomus. 45 



Colour. — Head (except eyes, which are black) and abdomen 

 brown; dorsum of thorax dark brown or blackish; sides of thorax, 

 coxae and trochanters 3'ellowish ; legs, antennae and palpi grey ; 

 the whole (especially the legs) exhibiting a strong silvery reful- 

 gence. Wings smoke-grey, with a strong bluish iridescence on the 

 disk and a general silvery refulgence. 



Head. — Rostrum elongate, sausage-shaped, ovoid as seen 

 from above. Eyes distinctly emarginate on their internal upper 

 border, narrowly separated. Antennae with 14 joints in the 

 flagellum, all of which are more or less elongate and each of which 

 bears three or four somewhat irregular verticels of stiff, fine hairs ; 

 the proximal joint of the scape clearly separated from the head, 

 rather slender, short ; distal joint suhspherical, bearing a circle of 

 suberect, narrow, spatulate, curved scales and (alternating with and 

 below the scales) another of stiff bristles. Palpi with five joints ; 

 the basal joint short, the second joint more than half as long as 

 the third, which is as long as the fourth and fifth together. 



Thorax. — The dorsum is covered with long, stiff, upright, 

 curved hairs 



Abdomen slender and cylindrical in both sexes, considerably 

 shorter than the wings, covered with rather slender curved hairs 

 of irregular length but never very long or stout. 



Willis bluntly pointed ; the posterior border much more 

 strongly curved than the anterior. The anterior branch of the 

 second longitudinal vein much longer than the distance between 

 its base and the second fork; the stem of the vein between the 

 second fork and the mid cross-vein slightly longer than the 

 distance between the two forks ; the posterior fork nearly on a level 

 with the fork of the fourth vein. 



External genitalia. — ( ? ) The superior a])pendages somewhat 

 widely separated from the inferior, which are small, pointed and 

 claw-shaped. ( cf ) All the appendages long and apparent. The 

 inferior appendages somewhat slender, laterally compressed, 

 longer than the basal joint of the superior appendages, oblicjuely 

 truncated, devoid of spines, covered with stout hairs, which form 

 a dense brush at the tip of the appendage ; a distinct elbow not 

 far from the base of the appendage ; the intermediate appendages 

 small, consisting of a stout, bluntly pointed dorsal lobe and a 

 small ventral lobe which is a minute, pointed process bearing a 

 bunch of bristles at the tip and attached to the ventral margin of 

 the dorsal lobe. The superior appendage with the distal joint 

 considerably shorter than the proximal one, bearing five stout, 

 pointed cha^ta.^ each nearly as Ipng as the joint, arranged as 

 follows :- -a single cliaeta at a point about a third of the length of 

 the joint from the base, a pair of slightly une(jual chictic near the 

 middle of the joint, and a terminal equal pair. The ])r()xiinal 

 joint slightly longer than the last apparent segment of Ihc abdo- 

 men. Intromittent organs relatively long, ensiform, consisting of 

 two slender, i)ointed lateral valves, between which a pair of long 

 filaments caii be protruded.
