1888.] FROM WESTERN INDIA. 299 



Family Psychid^. 



31. Psyche longicatjda, sp. n. (No. 223.) 



"Wings dull fuscous ; the costa of the fore wing more thickly- 

 scaled, and so appearing darker ; the rest of the wings semidiapha- 

 nous. Thorax and abdomen clothed with long shaggy fuscous hair ; 

 the latter ending in a prolonged tuft of smoky-black hairs ; antennae 

 of the same smoky-black hue. Expanse 30 millim. 



One male, bred November 8, 1886, from Campbellpore, accom- 

 panied with the remark "that the larva makes a faggot of straws." 

 These cases are an inch and half long ; the inner part composed of 

 grey silk into which apparently the empty seed-cases of a grass have 

 been spun ; this is covered externally with small lengths of shining 

 yellow flower-stems of the grass ; those at the base closely packed 

 and shorter, about ^ inch long ; those on the sides longer and 

 projecting beyond the apex. 



Family Notodontid^. 



32. MOMA CHAMPA. (No. 156.) 



Mo7na Champa, Moore, P. Z. S. 1879, p. 483, pi. 33. fig. 2. 

 A pair from Thundiani, taken in August 1886. 

 Recorded also from the Cameroons and the Congo. Mr. Moore's 

 types were from the N.W. Himalayas. 



Family Cymatophorid^. 



33. Thyatira cognata. (No. 104.) 

 Thyatira cognata, Moore, MS. 



One female from Kala Pani, dated August 9, 1886, somewhat 

 wasted. 



Allied to T. vicina, Gn., from Java, but the fore wing has only 

 four peach-coloured patches, that on the inner margin being filled 

 up with the fuscous-olive ground-colour, and only visible in outline. 

 As in vicina, the basal blotch is prominently produced in the centre, 

 hut the two subapical blotches are not confluent. 



A comparison of a more extensive series of specimens of this form, 

 in the Hocking Collection in the British Museum, in which there 

 occurs considerable variation in the distinctness of the blotch on the 

 inner margin, has led Mr. Butler to consider this a mere variety 

 of T. baits, and not a distinct species. In this he is, I have no 

 doubt, right ; but it must still be considered a merely local form, 

 and not a variety of general occurrence. 



34. PoLYPLOCA albidisca, Moore, MS. 



Fore wing greyish white, with a greenish tinge ; extreme base 

 blackish, with a tuft of raised white scales ; followed by a pale grey 

 sinuous band, indistinctly traversed by a darker central line ; then a 

 dark-edged darker sinuous fascia, also traversed by an indistinctly 

 darker line ; the external angle of this fascia below the costa is 

 marked by a short vertical black dash of raised scales, representing
