1920.- 171 



dorsal segments 1-4 each with a iiatteiied angular space in the middle in 

 front, 1 sometimes with au indication of a smootli median line, 7 armed with 

 a slender spine on each side towards the tip. Tarsi slender, joint -1 simple ; joint 

 1 of posterior pair nearly as long as 2-4 united. 

 Length 4^-5 mm. ( 5 ?) 



Hah. W. Almora, Kumaon (H. G. C: vi.l917, vii.lOlS). 



Five specimens, assumed to be $ $ , the sixth ventral segment 

 being uneraarginate. Separable from ^S*. {Hemistenus) virgula, S. pos- 

 ticus, and other similarly coloured forms described by Fauvel by the 

 simple fourth tarsal joint and the bidentate seventh dorsal abdominal 

 segment. ^S^. kraatzi Bernh. (1911), from Simla, must be nearly allied to 

 S. hidentatus ; it is described as black, with the legs testaceous (the 

 apices of the tibiae excepted), the elytra with a small spot, the head 

 carinate down the middle, and presumabl}^ has the abdomen unarmed. 



Stenus mucronatus, sp. n. 



Robust, broad, shining, very finely, sparsely pubescent ; bronze-black, the 

 antennae (except towards the ti])), palpi, and legs i^the blackish knees excepted) 

 testaceous ; the head, prothorax, and elytra coarsely, densely, couflueutly 

 punctate ; the abdomen also coarsely closely punctured, with a row of laroer 

 impressions across the bases of segments 1-4, the ventral surface with smaller 

 punctures. Head large, broadly depressed between the eyes; antennae short. 

 Prothorax barely as long as broad, widest before the middle, and narrowing 

 thence to the base, canaliculate on the disc. Elytra wider than the head, much 

 broader than long, obliquely truncate at the apex. Abdomen sharply margined. 

 Tarsal joint 4 simple. 



(f. Sixth ventral segment triangularly emarginate ; posterior tibiae 

 sinuous within, slightly bowed inwards at the apex, and armed with a short 

 tooth at the inner angle, the intermediate pair also feebly sinuate within. 



Length 5-5^ mm. ( c? $ ■) 



Hab. W. Almora, Kumaon (H. G. C: xii.1917). 



Four males and four females. A rather broad, very rugose, bronze- 

 black form, with a subtrapezoidal, grooved prothorax, short elytra, 

 margined abdomen, and simple tarsi ; the posterior tibiae curved and 

 mucronate at the inner apical angle in S- This species superficially 

 resembles S. {Hypostenus) ventricosus Fauv. (1904), from Belgaum, but 

 the latter has an immarginate abdomen, a bilobed fourth tarsal joint, etc. 



Stenus seminiger, n. sp. 



Black, shining, the head and prothorax rather dull and with a l)rassv 

 lustre, the basal joint of the maxillary palpi testaceous, the tarsi piceous, sparsely 

 finely pubescent. Head large, densely, roughly punctate, broadly hollowed 

 between the eyes. Prothorax oblong-cordate, a little wider than the intra-
