also very bristly, armed at apex with a sharp horizontal tooth, last 

 joint of maxillary palps obliquely truncate from side to side ; labrum 

 rounded laterally, head with a strongly arcuate impressed line 

 reaching the apex of the genae which are short and do not form a 

 very high antennal crest ; antennae slender, short, barely reaching 

 the base of the prothorax, the five basal joints are less pubescent 

 than the others, the third longer than the fourth, 7-10 sub-triangular, 

 the two penultimate ones more produced inwardly at the apex than 

 outwardly, the last one oblong ; prothorax parallel ; scutellurn short, 

 triangular at the apex ; elytra broader than the prothorax at the 

 base, plainly ampliated in the posterior part, slightly convex, sloping 

 behind from two-thirds of the length ; epipleural fold continued from 

 the base to the apex ; prosternum with a strong, elongated, hori- 

 zontal cuneiform process, mesosternum with a cavity with raised 

 edges for the reception of the prosternal process ; legs somewhat 

 short but with the shape and vestiture of Strong ijlium, to which 

 genus the present one is allied. 



The species for which this genus is proposed has a peculiar 

 facies, very different in shape and sculpture from those of the African 

 species of Strongylium.

Greenish - bronze, moderately shining, clothed with short, 

 fulvescent hairs, antennae ferrugineous with a brassy tinge ; head 

 deeply and moderately closely punctured, labrum short, rounded, 

 not in a horizontal line with the epistorne, somewhat densely 

 pubescent ; prothorax nearly parallel, and with the anterior and 

 posterior angles sharp, but not projecting, carinate all round, covered 

 with deep, round punctures separated on the disk by smooth intervals 

 equal in width to their own diameter, but raised and irregular on the 

 sides, it has a deep elongated basal median impression continued as 

 a narrow impressed line as far as the apex, and a deep, elongate- 

 quadrate impression on each side of the median part, the pubescence 

 is moderately dense ; scutellum very short, punctulate at the base ; 

 elytra plainly ampliated laterally from the median part, one-fourth 

 wider behind than across the base, moderately densely pubescent, 

 and having on each side five more or less regular series of very deep, 

 elongate fossae-like impressions, as well as regular series of mode- 

 rately deep but somewhat distant punctures continued, but less 

 distinct, through the fossae, in the declivous posterior part are 

 some rounded deeply rufescent tubercles also covered with hairs like
