Trilocha albicolliS; Walker. 



Larvae of this species were found by Forsayeth in August, feeding 

 upon Pipul {Ficus relir/iosa) in Mhow, the moths emerging' the same 

 month (Trans Ent. Soc. Lond. p. 408, 1884). Forsayeth's description 

 and figures of the various stages of the insect agree very closely with 

 the T. varians of Calcutta, and it would seem by no means improbable 

 that the two forms are little more than varieties of each other. A third 

 species — Trilocha cervina, was described by Walker (Brit. Mus. Cat. Lep. 

 Het. xxxii, p. 489, 1865) from India ; but no particulars are given beyond 

 a bare description of the moth. The precise locality is unknown, and 

 there are no specimens in the Indian Museum ; so, the form must 

 either be extremely rare or identical with one of the better known species, 



OciNAEA LiDA, Moore. 



This species was originally described (Cat. Lep. Mus. E. I. C, p. 381, 

 1858) from Java, and an account of its habits was subsequently given 

 (Trans. Ent. Soc. Lond. 3, 11, p. 326, 1864—66) by Hutton, who named 

 it in the first instance 0. moorei, but afterwards recognized its identity 

 with 0. lidaoi Moore (Journ. Agri. Hort. Soc. Ind. Ill, p. 125, 1871). 

 Hutton found it between 5,000 and 6,000 feet elevation in Mussoorie in 

 the North- West Himalayas, where it feeds upon the leaves of Ficus 

 venosa, and spins a small white oval cocoon. The cocoon is generally 

 enveloped in a le'af, and covered with loose silk ; it is to be found both in 

 May and August, and Hutton supposed that at least two, and perhaps 

 three or four, generations are gone through in the year. He considers 

 the cocoon too small to be of any use. The larva is rough and resembles 

 the bark so closely as to be very difficult to be distinguished from the 

 latter upon the twigs to which it clings. 



OciNARA LACTEA. Flate 10, fg. 3 (Hutton, Trans.Ent. Soc. Lond. 3, IT^ 



p. 382,1864-66). 



This species was found by Hutton feeding with 0. lida upon FIcus 

 venosa in Mussoorie. The two forms are evidently closely allied and have 

 very similar habits, but Hutton was of opinion that they are distinct, and 

 as there are no satisfactory specimens of 0. lida in the Indian Museum, it 

 has not been possible to compare them. 0. lactea is represented in the 

 Museum collection by specimens from Sikkim and Kulu, as well as from 

 Mussoorie ; so, it is probable that the species extends throughout the Hima- 

 layas, though it is too rare and the cocoons are too small for it to have any 

 value as a silk producer. The figure of the moth is from Captain Hut- 

 ton's specimen in the Indian Museum \ that of the larva is after Captain 

 Button's figure in the Trans. Ent. Soc. Lond,
