Nitid black with the antennae, the parts of the mouth 

 and the legs with the coxae piceous or brown. Head large, 

 smooth, between the antennae with two broad shallow 

 impressions , united in front by an impressed transverse 

 groove , behind the eyes with a deeply impressed pit , both 

 pits united by a more or less visible shallow arcuate im- 

 pression on the vertex. Antennae long, extending beyond 

 the base of the thorax. Prothorax not broader than the 

 head, subcordiform , the front angles rounded, the sides 

 rounded and moderately emarginate before the posterior 

 angles, which are almost quadrangular, the basal margin 

 straight ; the disc rather smooth , very faintly wrinkled in 

 a transverse direction, with a deep and broad linear im- 

 pression in the middle, not quite reaching the front and 

 basal margins , just along the lateral margins provided 

 with a fine costa and along the innerside of the costae 

 with a broad impression, very conspicuous near the base 

 but becoming the more and more obsolete towards the 

 top. Elytra twice as broad as the thorax at the base , the 

 shoulders obsolete and broadly rounded , the sides almost 

 straight and parallel , at the apex gradually rounded with 

 a slight emargination before the top ; striated , the striae 

 faintly punctate, the punctures increasing in size near the 

 margins, the intervals plain and impunctate except three 

 large punctures on the third interval , one close to the base , 

 an other below the middle and the third near the apex, and 

 a single pit on the fifth interstice near the top. Underneath ra- 

 ther smooth , a few large punctures on the prosternum and 

 the last ventral segment rugosely striated and provided on 

 each side of the upper margin with three piliferous punctures.
