in the Hopeian collection at Oxford were botli collected by Mr. A. R. Wal- 

 lace, at Sarawak, in Borneo. 



Ohs. It is j)ossible that the Sinkieb specimen, when actually compared 

 with Westwood's typical one, may turn out to differ in much the same 

 manner as the species of Bacteria from the same island does from B. Sar- 

 aioaca, Westw.

The Indian Museum has long possessed numerous examples of N. Jiila- 

 ris ^ $ , both from Sikkim (i. Mandelli) and from the neighbourhood of 

 Sibsagar, Assam (S. JS. BeaT) ; but the identification of the male as N, 

 Virhius, Westw. was only recently made by Professor Westwood and 

 myself while looking through the collection of Fhasmidcd in the Oxford 

 Museum.

" ? . Body elongate, stoutish, of tolerably uniform width throughout. 

 Head large, oblong, parallel-sided ; vertex divided by three notches into 

 four tubercles. Pronotum shorter and narrower than the head, flat, with a 

 few minute granules. Mesothorax slightly tapering from the insertion of 

 the legs forwards, granulate above and below and on the sides ; its dorsal 

 arc longitudinally carinate, granulate along the top of the ridge and at the 

 edges. Abdomen tapering slightly from the base to the emarginate apex, 

 which carries a longitudinally carinate semioval plate ; its terminal seg- 

 ments, dorsal and ventral, constructed much as in Necroscia Salmanazar^ 

 N. maculicollis, and JSf. Sparaxes, in all three of which also the sixth ven- 

 tral segment is furnished at its hinder extremity mth a peculiarly shaped 

 process, which serves as the ^point cVappui for the claspers of the male dur- 

 ing copulation.* Legs long and stout ; the fore tibiae and the femora and 

 the tibise of the two posterior pairs subtriquetrous and carinate along the 

 middle of the under surface. Tegmina oval, with but a slight compressed 

 conical elevation of the carina. Wings reaching about to the end of the 

 fifth abdominal segment ; the costal area luteous brown, like the body and 

 legs ; the costal vein divided at the middle of its length, the two branches 

 uniting again near the extremity ; posterior area milk-white, cons23icuously 

 * A fact ascertained by actual observation in JSf. maculioollis.
