JTi/drarna cirrnia, n. sp. 



(S . Elonp-ate-obnvate, robust, sliiniiio-; piceous, the aiitennao and palpi, 

 tlie expanded olytral margins, and sometimes the legs in part or entirely, 

 ferriiuinous. Head rather long, closely, roughly, the epistoma more finely, 

 punctured ; labrum very deeply emarginate ; terminal joint of the maxillary 

 palpi long, simply acuminate. Protiiorax much wider than the head, broader 

 than long, angularly dilated at the sides at a little before the middle and 

 sinuously narrowed tlience to the base, the hind angles rectangular, the anterior 

 angles sharp ; closely, roughly punctate, deeply foveate towards the sides 

 anteriorly, and with a short median furrow, the lateral margins crenulate. 

 ]^lytra oblong-oval, somewhat widened posteriorly, rather broadly explanate 

 laterally to near the tip; with numerous rows of moderately coarse, oblong 

 punctures, which are about as wide as the narrow, almost smooth interstices. 

 Beneath opaque, the ventral segments 5 (a triangular space in front and the 

 sides excepted) and 6 shining, 6 with two small pubescent areas in the middle 

 behind : metasternum with two subparallel ridges. Interruediate tibiae slightly 

 curved, armed along the median third of their inner edge with a row of short, 

 slender, oblique teeth. Posterior tibiae (fig. 1) abruptly bowed inward from 

 about the middle, broadly, triangularly dilated at the apex, the inner apical 

 portion sharply produced and furnished with a still', hook-like, matted tuft 

 of long curled hairs beneath. 



Lenjith 2iJ-.'3, breadth 1-1 1'j, mm. 



1. Hydraena cirrata, <^ , Posterior leg. 



2. Hijdi-aenabihamata, cJ , Posterior leg. 



3. Pentarin 'plniycnema, ^ , Anterior leg. 



JIah. IxDiA, W. Almora in Kuraaon (//. G. C. : v.1910). 



Twentj'-nine specimens, all males, no female having been found in 

 the extensive material of this genus received from Almora. A large, 

 robust form belonging to Kuwert's subgenus Hoplydraena., under which 

 he includes four species from eastern Europe or the Caucasus, all unknown 

 to me. H. cirrata is broader and more rohust than the European 

 H. carlonaria Kies., and it has the prothorax more dilated anteriorly, 

 the elvtral margins wider, etc.
