Elongatus, depressus, parallelus, piceo-testaceus, nitldus ; capife magno, 

 triatigulari, postice transversim fortiter impresso ; thorace capite parum 

 angustiori, latitudine paulo longiori, antice parum angustato ; elytris 

 flanatis, utrinque subcarinatis, intra carinam longitudinaliter impressis, 

 parcc, obsolete, subtilifer puncttdatis. Long. 2\ tin. 



General form and appearance of Prostomis mandihularis, but with the head 

 neai'ly equilaterally triangular ; elypeus trapeziform, truncate in front ; the punctua- 

 tion of the head and thorax is not close, and is very fine. Thorax a little longer than 

 broad, a little narrowed in front, the sides gently arcuate. Elytra as broad as the 

 head, with a lateral carina as in Cucujus, and with a faint longitudinal impression 

 within this carina ; the punctuation is very fine and obscure.

Helodes Atkinson:, sp. n. 



Ohlongus, piceus, griseo-2)iibescenti ; thorace fere semiclrculari, basi late 

 bi-cmarginato, elytris hand lineatis. Long. 3 liii., lat. If lin. 



Greneral form of H. lividus, but with the thorax nearly semicircular, a little 

 narrower than the elytra, broadest at the posterior angles, which (although their 

 extreme point is a little blunted) are a little less than right angles, the lateral 

 margins are a little impressed, the base is broadly but not deeply bi-emarginatc, the 

 two emarginations occupying the whole base. The scutellum is a trifle longer than 

 in H. lividus, not raised in the middle, extremely closely and rather finely punc- 

 tured. The elytra hare no traces of raised lines. The head is very closely and finely 

 granulate-punctate ; the three basal joints of the antennae are pitchy, the rest nearly 

 black. The punctuation of the thorax is extremely close and very fine ; that on the 

 disc of the elytra is less close and less fine, and quite distinct, that on the sides is 

 much finer and more close, especially posteriorly, wliere it becomes less distinct. 

 The epipleural fold of the elytra is at right angles with tlie side of the elytra, 

 slightly concave at the base, finely and rather thickly punctured.
