GROUP C. 



In this group the fourth joint is slender and very similar to the 

 third, the fifth broader (Fig. 307. Nos. 1 and 2). The species are, 

 for the most pmrt, smaller and more slender, rarely over 6 mm. in 

 length.

1524 (4734). AGRILUS SUBCINCTUS Gory, Mou. Buprest, IV, 1837, 252. 



Elongate-oblong, moderately robust. Piceous, with faint bronze lustre ; 

 elytra with two yellowish pubescent spaces, one extending from humeri to 

 middle, with two interruptions, then turning obliquely outwards; the sec- 

 ond oblique, one-fourth from apex. Occiput strigose and with a deep me- 

 dian impression. Thorax one-fourth wider than long, sides regularly curved ; 

 disk with a rather broad but shallow median groove extending the full 

 length and a well marked depression each side ; surface transversely stri- 

 gose at middle, obliquely so on sides. Elytra somewhat dilated behind the 

 middle, tips rounded and serrulate; disk slightly flattened with a vague 

 costa, surface with coarse scales. Prosternal lobe broadly emarginate.
