D. cameroni Champ. — A few more specimens have come to hand 

 from Jagthana, etc. Three from Sikkim are nigro-cyaneous in colour. 



D. sulvorticosus Champ. — Subsequently captured in profusion in 

 Almora. 



One additional Indian species has been described in the meantime by 

 Cameron, D. championi from Lebong, Bengal (Ent. Mo. Mag. Ivi, p. 145). 

 The Chinese D. ji^^osus Champ. (1919) =Z). hanqhaasi Bernhauer 

 (1916), whose paper was not received in London till 1920. 



Dianous ohliquenotatiis, n. sp. 



Very elongate, robust, bkii.sh-greeii or obscure cyaneoiis, the elytra brassy 

 on the disc and each with an oblique, rather large, orange streak just behind 

 the middle, the antennae, palpi, and legs black, the prothorax and the polished 

 portions of the under surface glabrous, the rest of the surface very finely 

 cinereo-pubescent ; the head, elytra, and abdomen densely, very minutely 

 punctate ; the prothorax shining, very sparsely, the depressed basal area some- 

 what coarsely, punctured. Head large, rounded at the sides behind the eyes ; 

 antennae moderately elongate. Prothorax convex, narrow, slightly longer than 

 broad ; with a very deep oblique farrow on each side behind the middle, the 

 two furrows coalescent on the disc and bounded posteriorly by a tuiuid space, 

 the depressed transverse space at the base sometimes with a smooth raised 

 median line. Elytra long, broad, longitudinally depressed within the humeri 

 and along the suture anteriorly (the intervening space appearing raised) and 

 obliquely grooved behind the orange streak, the latter tumid and smoother than 

 the rest of the surface. Metasternum and the ventral segments 1-4 with a 

 rather broad polished space down the middle. Legs rather stout, moderately 

 elongate. Fourth tarsal joint simple. 



Length 8^-9i mm. ( ? .) 



Hah. Rungbong, Gopaldhara, Sikkim {H. Stevens, in litis. Brit.). 

 Five specimens. A large, robust form, with an oblique, tumid, 

 orange streak on each elytron ; the elytra variegate, uneven, and sculp- 

 tured as in D. annandalei, versicolo?^ and inaeqiialis. Compared with 

 D. gracilipes, the legs are shorter and stouter, the antennae are not 

 nearly so elongate, the polished area on the under surface of the body is 

 less extended, and the fourth tarsal joint is quite simple. 



Dianous gracilipes, n: sp. 



Very elongate, obscure aeneous or greenish aeneous, the antennae, palpi, 

 and legs black, the prothorax and the polished portions of the under surface 

 almost glabrous, the rest of the surface very finely sericeo-pubescent ; the head 

 and elytra very densely, minutely, the abdomen a little more distinctly, punc- 

 tate, the prothorax shining and almost smooth, the basal portion only with a 

 few scattered punctures. Head very large, obliquely narrowed posteriorly, 

 broadly bisulcate between the eyes, the latter large ; antennae extremely elon- 

 gate. Prothorax convex, narrow, slightly longer than broad, much narrowed
