Head nearly as large as thorax, obsoletely bifoveolate in front. Eyes 

 slightly prominent, with coarse facets. Thorax of about equal length 

 and breadth, widest just before the middle, finely margined and feebly 

 bisinuate at the base, without impressions. Elytra nearly thrice the 

 length of thorax, slightly broader at the base, their sides a little rounded 

 near the hind thighs, with fine sutural striae. Hind-body deflexed, with- 

 out well-marked sculpture. Legs slender. 



Underside nitid, rufous, with some fine greyish pubescence. Meta- 

 sternum broadly medially depressed, the sides of the depression some- 

 what elevated backwards. Basal ventral segment large, flattened behind, 

 with a distinct tubercle close to each of the coxae; segments 2-4 very 

 short in the middle, the 5th with a large fovea. Anterior trochanters 

 spined. 



Antennae 10-articulate ; basal joint stout, cylindric; 2nd similar, 

 but shorter; 3rd rather smaller than 2nd, and narrowed towards the 

 base; 4th somewhat moniliform, and shorter than adjoining ones; 5th 

 subquadrate; these articulations bear slender pubescence only; the 6th 

 and 7th coalesce and are hardly distinguishable from each other, except 

 that the latter has short yet distinct brassy setae and is slightly obtusely 

 bulging at one side; 8th extremely short, sometimes overlapped by its 

 predecessor, all three rather broader than the 5th; 9th very large, 

 straight inwardly, longer and gradually becoming broader outwardly, 

 its front angle slightly curved and clasping the base of the 10th, its 

 apex oblique and slightly concave; 10th conical when exserted, sub- 

 rotundate when closely applied to the penultimate, nearly as broad as it 

 is; both of these bear finer setae than the 7th and are finely But quite 

 definitely granulate. 



Malformation of joints 6-8 of the antennae renders an accurate de- 

 scription of one male inapplicable to the other. It must be placed next 

 to 1645. 



Female. — Antennae 11 -articulate, joints 1-5 like those of the male, 

 their 6th joint of about the same size as the 4th, joints 7-9 transverse, 

 10th broader than 9th, 11th nearly twice as long as broad.

Oblong-oval, nitid, pubescence depressed, slender, pale flavescent ; 

 fusco-castaneous, head and legs rufescent ; tarsi, palpi, and basal three 

 joints of antennae testaceous, remaining joints fuscous. 



Head small, widest and somewhat angulate behind the middle, 

 ' narrowed anteriorly, moderately coarsely but not closely punctured. 

 Thorax large, the breadth nearly double the length, much curved an- 

 teriorly, base truncate but with its angles slightly overlapping the 

 shoulders; it is much more finely punctate than the head, indistinctly 

 on the middle. Scutellum triangular. Elytra nowhere broader than the 

 thorax, and quite twice its length, gradually narrowed posteriorly, the 

 apices not at all acuminate; with fine sutural striae, and moderately close, 

 transversely strigose sculpture. 



Antennae as long as head and thorax, gradually incrassate, finely 

 pubescent ; 2ml joint rather longer than 3rd ; 4th and 5th longer than
