converge downwards and unite so as to form a single inedian cailua 

 on the lower part of the face. Prothorax rounded at the sides, 

 widest behind the middle, narrowed gradually in front more 

 strongly towards the base, slightly raised and subasperate along 

 the middle of the disc ; marked with two rounded dark brown spots 

 on the disc and a smaller one on each side ; the disc more or less 

 infuscate in the middle, especially towards the base. 



Length 11-17 ; breadth 3-5 mm.

This species varies considerably in colour and to some extent 

 also in the markings. In some specimens the derm is of a 

 yellowish-testaceous colour in parts, in others almost entirely 

 dark brown. The pubescence is sometimes yellowish, some- 

 times ashy grey. The postmedian baud of the elytra is often 

 interrupted or broken up into spots, and occasionally almost 

 disappears.

Dark brow-n, with a tawny or greyish-tawny pubescence that 

 covers the head and prothorax and forms bands on the elytra ; 

 prothorax with a median asperate band which is widened towards 

 the base, two lateral spots on the disc, and a small spot on each 

 side, black; the elytral bands arranged as follows: — (1) a baud 

 which crosses the base of each elytron from the shoulder, curves 

 backwards near the scutellum and runs close along the suture 

 for a short distance, then diverges from the suture and curves 

 outwards to the side at about one-third from the base, turning 

 forward a little before it reaches the outer margin ; (2) a short, 

 slightly oblique, transverse band on each a little behind the base ; 

 (3) a band that passes obliquely outwards from the suture at 

 about two-thirds of its length from the base ; (4) a band at the 

 apex. Body beneath with a large spot of yellowish-white pubes- 

 cence on the hinder half of each of the metathoracic episterna, 

 sometimes with a smaller spot on the anterior part ; a lateral 

 transverse spot of the same kind on the posterior half of each of 

 the first three abdominal segments. Vertex of head with a fine 

 median carina which divides anteriorly into two finer ones ; front 

 with four carina;, the lateral pair extended downwards as far as 

 the middle of the front border of the eyes ; the intermediate pair 

 converge and unite below so as to form a single median carina on 

 the clypeus. Antenuaj reach a little past the base of the pro- 

 thorax in the $ , slightly longer in the S ; the last two or three 

 joints somewhat thickened. Prothorax rounded at the sides, 

 widest behind the middle, iiarrowed gradually in front, more 

 strongly towards the base.
