304 Records of the Indian Museum. [Vol. IV, 



Wings with a depressed row of elongate brown scales on each 

 side of each vein, from the base to beyond the middle of the wing 

 where the}^ gradually become narrower until eventually, towards 

 the margin of the wing, they are replaced by stiff hairs. They lie 

 close together, although not always touching one another, and are 

 long enough to overlap those emanating from the adjacent veins. 

 A distinct spot of bristly black hairs at the tip of each vein, and 

 apparently a slightty clearer spot in the wing immediately in front 

 of the vein- tip. 



Described from a single specimen (apparently a 9 ) in the 

 Indian Museum taken by Dr. Annandale at Kurseong, 4-viii-o8. 



N.B. — A very distinct species from all others, readily dis- 

 tinguished by the conspicuous, scaled veins. 



Pericoma spinicornis, mihi. 



P. appendic'ulata, mihi. 



As noted in the original descriptions these two forms re- 

 present the sexes of a single species. There can be no reasonable 

 doubt about the point, although no actual pair has been found 

 in cop. The number of spines on the first flagellar joint in the 

 <f is six : the palpi consist of four subequal, oblongo-cylindrical 

 joints. 



The Indian Museum possesses a good series giving the follow- 

 ing data: Darjiling (7,000 ft.), 26 — 28- v-io and 2-X-08, common 

 [Brunetti]; 8 — ii-vni-og [Jenkins]; 6 — ic-viii-09 [Paival; Kurseong

 dale]; Phagu (9,000 ft.), ii-v-09 [Annandale]; Naini Tal (6,000 

 ft.), 2-vi-09 [Hodgart]. 



Pericoma annandalei, mihi. 



Eight examples of this species have been acquired b}'' the 

 Indian Museum, captured by Dr. Annandale at Kurseong, 

 22 — 29-vi-io, where he found them running over Caladimn leaves 

 at dusk, in thick jungle. 



Pericoma margininotata, mihi. 

 P. hell a, mihi. 



Long. i|^ — 1| mm. 



From a good series of this species (with which must be in- 

 cluded the form described as hella), recently acquired by the 

 Indian Museum, it is possible to emend the original description. 

 The species is very variable in its coloration. 



The 2nd scapal joint is subglobular, a little more than half as 

 long as the ist, which is cylindrical, twice as long as its width. 

 The flagellum is composed of either fifteen distinct joints, or of
