but is continued in a series of a sharp erect spine or tubercles, the 

 suture is spinous and between it and the costa is a line of mimite 

 tubercles ; there are two other series of tubercles outside the 

 second costa ; margins very narrow.

Dull blackish-brown, glabrous, ovate. Antennas and head as in 

 B. ovatus, the latter a little more square and flattened. Thorax 

 smooth, very rounded laterally, transverse and sinuate behind, the 

 disk convex, the median line raised, more strongly posteriorly, the 

 margins broad and rugose, the borders folded above, the anterior 

 angles very acute, touching but not crossing in front, the pos- 

 terior strongly recurved backwards. Elytra rounded posteriorly 

 and very slightly acuminate at the apex, the humeral angles 

 obtuse, the disk oval, convex, on each side of the suture are two 

 rows of sharp tubercles some of these, particularly near the base, 

 are of elongate form, the row or costa along the suture diverges 

 in front towards the scutellum, of which it takes the direction the 

 costa of the middle of the elytra forms a narrow line, these c'ost^ 

 are obliterated towards the apex, as well as the tubercles which are 

 irregularly spread over the interstices, the whole surface is coarsely 

 punctate, the margins are smooth and not raised, broad at the 

 humeral angles, narrowing to almost none at the apex.

Genus Sym petes, Pascoe. 



Journ. of Ent. II. p. 464. 



A genus characterised by Pascoe as being separated from Helceus 

 by the anterior angles of the thorax not meeting in front of the 

 head, and from Saragus by the mesosternum having no notch for 

 the reception of the prosternal process. Labrum hidden.
