No. 1. ] ^ Darjiliiig Sal Pest. 67 



insect cuts its way out of the lower end of its cocoon by means of its 

 sharp edg-ed beak, propelling- itself forward by the aid of the two pointed 

 processes and the toothed seg-raents of the abdomen of the pupa shell. 



I have occasionally found the caterpillar singly on tea bushes adjoin- 

 ing sal forest, but, although they eat the leaves, they do not appear to 

 do so by preference, neither do they feed gregariously, as is the case with 

 the larvae of Govisana bipars (?) (Walker), which completely strips the 

 tea bushes it feeds on and often kills them by taking off the bark to 

 make its ease. 



[Note. — Since writing this, I have taken the larvae commonly on tea bushes at eleva- 

 tions of from two to three thousand feet above sea-level in this district.] 



VII.— A NEW PSYCHID INJURIOUS TO SAL.^ 

 By F. MOORE. 



Biimeta sikkima (no v. sp., Moore), nearest allied to the Ceylonese E. 

 lat/ardi (Moore, Lep. Ceylon, II, 102, pi. 118, fig. 2, $). Darker 

 coloured generally. Fore wing with the costal border, the area longi- 

 tudinally below the cell, and the posterior border darker brown ; the 

 veins also blacker. On the hind wing the general colour is also darker 

 throughout. Body much darker coloured, and the black tufts of hairs 

 on thorax and abdomen more prominent. Expanse of wings If inch. 



Ilahitat. — Sikkim. 



The larva feeds on the sal {Shorea robusta), and forms a large fusi- 

 form case longitudinally covered with leaves of the tree, and before 

 pupating suspends the case to an adjacent twig. 



[ Note. — E. siTckima is quite distinct from the Ceylonese 1£. orameri and its ally the 

 Bombay E. leithii, both of which latter species are much smaller in size, and each have 

 the antennal combs on both sides of the shaft about half the length of those in J^J. 

 layardi and E. sikkima, the breadth of the antennae in both the latter species being 

 conspicuously broad. All the species of the genus Eumeta are much alike, superficially. 

 JS, orameri, E. leithii, and E. layardi are stated to form twig-covered cases, whereas 

 the Sikkim species covers its case with leaves.] 



^ The life-history of this species is described above by Mr. Q. C. Dudgeon.
