XILOTBECHUS. 243 



This species is very closely allied to X. smei, Lap. & Gory, the 

 differences which it presents are very slight. It is generally 

 darker in colour, and the basal band of each elytron curves round 

 by the scutellum and is continuous with the sutural band.

Closely allied" to X. smei, Lap. & Gory, and X. subscutellatus, 

 Chevr. This species differs from both in that the white spot on 

 the anterior part of each of the metathoracic episterna is nearly as 

 large as the spot on the posterior part, also the two spots are 

 joined. The elytra are light brown or slightly reddish in colour 

 in the neighbourhood of the anterior, sutural band ; this lighter 

 coloured part is somewhat in the shape of a triangle with its base 

 in front.

Dark brown, with greyish or tawny-yellow pubescence that covers 

 the head and prothorax and is formed into bands on the elytra ; 

 prothorax without spot at the sides, the disc with a median band, 

 which is widened and somewhat rounded at the base, narrowed in 

 front, and two large lateral spots, black ; elytral bands arranged 

 as follows : (1) a transverse band at the base ; (2) a short sutural 

 band which begins at a little distance behind the scutellum, at its 

 hind end turns outwards almost at right angles and then passes 

 straight across the elytron to the side ; (3) a short transverse 

 band a little behind the base, which is bent backwards at its outer 

 end and almost touches the sutural band ab its inner end ; (4) a 

 transverse band at about one-third from the apex, this band pro- 

 duced forward in a triangle at the suture and sometimes also 

 angulated behind at the suture ; (5) an apical band produced at 

 the suture, with its front border strongly oblique. Body beneath 

 with a pubescent white spot on each of the mesothoracic episterna, 

 another near the antero-lateral angles of the metasternum, two 

 spots on each of the metathoracic episterna, and four almost com- 

 plete bauds on the abdomen.
