peculiar shape of the fastlgium of the vertex ; the latter character is so 

 peculiar that it is possible that a new genus may be based on this 

 structure, when the male of C. mitchelli is discovered. The type is in 

 the British Museum.

NEW SPECIES OF STAPHYLINIDAE FROM INDIA (2). 

 BY MALCOLM CAMEROIS^, M.B., F.E.S. 



The following species are described in this contribution. The types 

 are in the Natural History Musevim. S. Kensington, except where 

 otherwise stated. 



Dianous bisignatus. Creophilopsis (n. gen.) semiaeneus. 



Lathrohium semicaeruleum. Qitedius (Raphirus) rvgosiis. 



Pammegus andreivesi. Placv^a intermedia. 



Dianous hisignatus. n. sp. 



Black, shining, the head, thorax, and abdomen (above) scarcely aeneous, 

 the elytra with a small round dull oranf^e spot a little behind the middle, and 

 distinct <>reenish-copper and violaceous reflex, especially posteriorly. Antennae, 

 palpi, and legs black. 



Length 6 mm. 



Amongst the Indian species with spotted elytra intermediate between 

 D. luteoguttatus and distigma. Champ., in general appearance nearer the former, 

 but differing in the following respects: the head is not so broad, the vertex is 

 more elevated, so that the intra-ocular furrows appear narrower and deeper, 

 the eyes are smaller and the puncturation coarser, the thorax is more enlarged 

 in front and the sculpture yet more coarse, the orange spot on the elytra is 

 duller, the metallic reflex more pronounced, and the 4th joint of the tarsi is 

 narrowly bilobed ; from distigma by the scarcely metallic head, thorax, and 

 abdomen, smaller elytral spot and much more rugose sculpture of the thorax 

 and elytra. 



Head black, shining, in certain lights with trace of aeneous reflex, broader 

 than the thorax, the intra-ocular furrows distinct, converging in front, coarsely 

 and closely punctured. Antennae black, long and slender, all the joints longer 

 than broad. Thorax with the sides rounded and dilated before the middle, 

 nearly parallel posteriorly, the disc more or less obliquely impressed on either 

 side; sculpture coarse, consisting of large, more or less confluent punctures 

 (especially in front and on the sides) which form rugae posteriorly. Elytra 

 much wider and distinctly longer than the thorax, longer than broad, feebly 

 impressed internal to the shoulders ; sculpture in front consisting of coarse 

 confluent punctures, verticose-rugose behind. Abdomen very finely, closely,
