16 a. Stilicopsis thoracicus, sp. n. 

 Black, greasy-lustrous, the elytra shining rufo-testaceous, 

 each with a black median band extending from the lateral 

 mnrgin nearly to tlie suture; abdomen black, shining, the 

 apex obscurely testaceous. Antennae and legs testaceous. 

 Length 2 mm. 



This species is remarkable in the strongly coriaceous, but 

 almost impunctate thorax, which is also narrower than is 

 usual in this group and approaches more to that of Astenus. 

 Apart from this, however, the build is similar to that of 

 Stilicopsis. 



Head large, subquadrate, the temples rounded, the eyes 

 rather small. Puncturation moderately close, superficial and 

 umbilicate, the interspaces distinctly coriaceous. Antennae 

 short, the third joint as long as the second^ the fourth and 

 fifth a little longer than broad, the sixth to the tenth trans- 

 verse, gradually increasing in breadth. Thorax scarcely 

 longer than broad, widest before the middle, the anterior 

 angles rounded, the sides obliquely contracted in front to 

 the narrow neck, posteriorly less strongly contracted to the 

 rounded posterior angles ; the sculpture distinctly coriaceous, 

 with a few obsolete umbilicate punctures sparingly distributed 

 and scarcely noticeable ; disc in the middle with trace of 

 median line, which is, however, not shining. Elytra a little 

 longer and distinctly wider than the thorax, almost as wide 

 as the head, longer than broad, shining, moderately finely 

 and moderately closely punctured, finely pubescent. Abdo- 

 men narrowed at the base and apex, extremely finely and 

 moderately closely punctured throughout and very finely 

 pubescent.
