opposite in the genus Helochares. I believe this species to be not 

 closely allied to any other of the group. 



Head with closer and deeper punctuation than on the prono- 

 tum, distinct impressed antenno-frontal and backwards disappear- 

 ing sagittal sutures. Gular sutures broadly separated. Prefrons 

 red on each side, with slightly emarginate and microscopically 

 striolate anterior margin, a group of a few coarser antero-external 

 systematic punctures and any dispersed intraocular ones along 

 the antenno-frontal suture. Labrum very broadly transverse, 

 slightly emarginate. with microscopically striolate surface and 

 very irregularly placed punctures. First joint of antennae not 

 very long. 2nd pyriform, a little shorter, 3rd to 5th becoming regul- 

 arly broader, 4th very small, 6th subhemispherical, supporting the 

 three-jointed pubescent club, 7th and 8th of equal size, 9th ovoid 

 and much larger. Maxillary palpi of moderate length, a little 

 longer than the antennae, not darkened at the apex, length of joints 

 in the proportion of 1/123 i, 9/12, 10/12; 2nd joint thickened on 

 the apex, straight on the anterior convex on the posterior margin, 

 3rd obconic, 4th thickened in the middle, cut off at the apex and 

 slightly longer than the preceding one. Men turn polished, with 

 dispersed and irregularly disposed punctures, much excavated in 

 front. 



Pronotum of a deep black colour, with both sides red-mar- 

 gined, anterior angles rounded, posterior more angular. Antero- 

 external systematic series of coarser punctures placed near the an- 

 terior margin, straightened obliquely to the anterior angle and 

 then abruptly turned backwards along the external margin so as 

 to reach ^he little medio-external group. Scutellum a little longer 

 than wide with curved sides and very faint punctures. Elytra not 

 enlarged behind, punctured like the pronotum without sutural or 

 transparent striae, deep black, only very narrowly red-margined. 

 There are three regular discal series of very largely separated and 

 anteriorly effaced systematic punctures, also an exterior one more 

 prolonged on the front margin and a little more furnished with 

 punctures. Exterior margin provided with irregularly placed 

 coarser punctures 



Underside black, finely pubescent on the whole surface except 

 an unpunctured and shining oblong spot on the metasternum, just 

 before the posterior coxae. Thighs all pubescent except on the 

 knees, which are of the same red colour as the trochanters, tibiae 

 and tarsi. Claws with a faintly toothed process on the base.

 A single & of the species taken by Dr. Kemp in small tanks 

 at Dibrugarh, N.-E. Assam, i7-i9-xi-i9ii (No. 4147/19). 



I have compared this beetle with a large series in my cabinet 

 — Pondichery and Genji, viii'igoi — and am not able to point out 

 differences. This series was named by Regimbart who referred the
