210 PSYCHODID.*;. 



If the relative lengths of the joints of the leg are safe characters, 

 the variety marginatus holds an intermediate position between 

 typical P. argeniipes and P. major together on the one hand, and 

 the remaining species together, on the other.

$ . Body covered with bristly hairs giving a uniform golden 

 grey appearance, with very strong silvery reflections ; disc of the 

 wings with a bluish iridescence. Legs sometimes darker than 

 the abdomen. 



Head : rostrum somewhat conical, short, truncated in front. 

 Eyes widely separated, emarginate above. Antennae very long 

 (if bent backwards they would reach nearly to the tip of the abdo- 

 men), with scapal joints subspherical, the flagellar ones elongate, 

 slender, densely covered with soft whitish grey hairs. Palpi with 

 apparently five joints ; the basal one very short, the 2nd, 3rd, and 

 4th subequal, each shorter than the 5th. Thorax : in normal 

 specimens ground-colour brown, with bright conspicuous golden 

 yellow hair ; in the dark variety much as in P. argentipes, though 

 usually brighter yellow. Abdomen long and slender, the ground- 

 colour pale brownish yellow, clothed with long recumbent pale 

 yellow hairs and with tufts of longer, upright ones on the dorsal 

 surface. Genitalia of male with upper and lower appendages 

 similar to those of P. aryentipes, except that they are more slender 

 and elongate, the basal joint of the upper appendage being nearly 

 twice as long as the last apparent joint of the abdomen ; the 

 intermediate appendages devoid of a ventral lobe ; valves of the 

 intromitteiit organ slender and blunt ; genital filaments well 

 developed. Legs generally concolorous with the body, sometimes 

 darker. Hind leg two and a half times a, long as head, thorax, 

 and abdomen ; its femur less than half as long as the tibia, and 

 considerably shorter than the metatarsus, which is longer than 

 the remaining joints together. Wings moderately broad and 

 pointed, the hairs nearly whitish grey. The 1st longitudinal vein 

 nds at two-thirds of the wing's length, the forks of the 2nd and 

 4th veins are opposite one another ; the fork of the upper branch 

 of the 2nd vein some distance before the tip of the 1st vein ; the 

 petiole of the 1st submarginal cell half the length of the cell. 



Length 3-3f millira. 



Outer Himalayas ; from the base up to 7000 or 8000 ft. ; 

 Paresnath Hill in "West Bengal in April ; Naini Tal, Bhowali
