Shortly oval, convex, black, and shining ; forehead ob- 

 scurely punctulate, with two shallow impressions close to the 

 stria, stria complete and bisinuous anteriorly ; the thorax, 

 marginal stria fine and complete, lateral stria well marked, 

 shortened before the base, and anteriorly hamate and ceasing 

 behind the anterior angle ; the elytra, subhumeral stria 

 wanting, 1-4 dorsal complete, 5 reaches just beyond the 

 middle, 6 is a little longer ; the pygidia have microscopic 

 punctures, with some of a larger grade intermixed ; the pro- 

 sternum, anterior lobe bistriate and obtusely acuminate at its 

 point and slightly bent downwards ; the mesosternum is 

 anteriorly nearly straight, but slightly prominent in the 

 middle, the marginal stria is complete but very fine; the 

 anterior tibiae, apical tooth very robust and minutely bifid at 

 the apex, with three minute teeth behind it; the other tibiae 

 are multispinous. 



The lateral stria of the thorax in this species is a marked 

 characteristic ; it may be placed near II. terrcemotus, Lew. 



Hab. Madura, S. India. 



Atholus ruptistrius, sp. n. 



Ovalis, convexus, niger, nitidus ; fronte biirapressa, stria intogra 

 retrorsum angulata ; pronoto stria marginali antice late inter- 

 rupta, stria interna pone oculos interrupta ; elytris striis integris, 

 5 cum suturali connexa ; propygidio haud dense punctato ; meso- 

 sterno truncate, marginato ; tibiis anticis 3-dentatis.

Oval, convex, black, and shining ; the forehead, surface 

 punctulate, with two shallow impressions behind the stria, 

 stria acuminate in the middle ; the thorax irregularly punc- 

 tured at the anterior angles within the stria, marginal stria 

 ceases behind the eyes, lateral stria is markedly broken 

 behind the eyes, but it is continued in a straight line with 

 roughened edges behind the head, towards the base the stria 

 is feebly sinuous and the interstice somewhat widens ; the 

 elytra, striae, inner subhumeral dimidiate and apical, the 

 dorsal striae are all complete, 5 and sutural join anteriorly ; 

 the pygidia are clearly but not closely punctate ; the pro- 

 sternal keel is narrow ; the mesosternum is truncate and the 

 stria complete ; the anterior tibiae 3-dentate. 



The form of the inner thoracic stria distinguishes this 

 species from its congeners coalescens, lk-striatus, and others. 

 The inner stria resembles that drawn by Marseul for Platy- 

 soma carolinum, Mon. pi. vii. fig. 14 (1853), but the stria is
