CNEMACANTHIDAE. 673 



and irregularly wrinkled. Eyes moderately prominent, the genae some- 

 what swollen behind them. Thorax only a sixth broader than long, its sides 

 slightly crenulate and flattened, gently curved to behind the middle and 

 sinuously narrowed towards the obtusely rectangular basal angles ; discal 

 groove distinct, not attaining the feebly emarginate base or apex, the 

 common longitudinal striae obsolete near the latter, the basal ones distinct ; 

 the surface with fine transverse striae, more feebly impressed before the 

 centre than elsewhere ; posterior fossae rather elongate and deep, extend- 

 ing to the basal margin and distinctly wrinkled, near each anterior angle 

 there is an impunctate transverse impression. Elytra elongate-oval, 2^ 

 times the length of thorax, only a little broader than it is near the 

 middle ; they are rather finely punctate-striate, third and fifth interstices 

 rather broader and more convex than the second, fourth and sixth narrow 

 and convex, seventh as convex as fifth but narrower, with four or five 

 more or less obvious punctures, the usual smooth lateral space on each 

 is narrow" and not distinctly marked off from the series of marginal 

 punctures. 



Antennae stout, evidently pubescent from their fourth joint onwards. 



Flanks of prosternum closely and moderately finely punctate, the rest 

 of the lower surface, except the closely sculptured mesosternum, irregu- 

 larly and finely striate, the last abdominal segment quadripunctate at 

 its extremity. 



Length, 30 mm.; breadth, 9 mm. 



Bluff. A damaged specimen, picked up dead, on the 1st December, 

 1914, by Mr. A. Philpott, whose name has been attached to it. The 

 elytral sculpture is distinctive. 



42G1. Mecodema ventriculum sp. nov. 



Elongate, slightly convex and nitid : black. Antennae and legs nigro- 

 piceous, tips of palpi rufescent. 



Head nearly as broad as front of thorax, forehead smooth, coarsely 

 longitudinally rugose near the moderately prominent eyes in front, punctate 

 right across behind these, the occiput with distinct irregular linear im- 

 pressions ; labrum rounded in front. Thorax very slightly broader than 

 long, wider near the middle than elsewhere, incurved at apex, lateral 

 margins only moderately rounded and crenulate, abruptly narrowed 

 towards the subrectangular posterior angles; disc almost smooth on the 

 middle, irregularly transversely striate towards the sides, with numerous 

 short frontal and basal striae, the central groove well marked but hardly 

 attaining the base or apex, basal foveae deep, not quite reaching the 

 hind margin. Elytra slightly broader than thorax, twice its length, finely 

 marginate, strongly curvedly narrowed behind ; their sculpture very 

 irregular, each indefinitely biseriate-punctate alongside the suture, with 

 unequal, principally large foveiform impressions towards the sides, marginal 

 punctation much finer and closer. 



Underside shining. Prosternum smooth along the middle, broadly and 

 deeply sulcate between the coxae, its flanks closely rugose-punctate, as 

 are those of the mesosternum. Sides of metasternum and basal ventral 

 segment moderately punctate ; fourth segment finely transversely strigose 

 at the base, with several short rather deep, longitudinal apical striae 

 which almost obliterate the pair of setigerous punctures at each side. 



This may be placed near M. venator (1452). 



S- Length, 25 mm. ; breadth, 8 mm.
