322 Mr. W. F. H. Blandford on new 



an impunctate median space and a slight transverse impression 

 at the base of the rostrum ; the latter narrower in the male, 

 with the side-margins more elevated and* frontal surface natter, 

 pubescence short in both sexes ; antennal club acuminate- 

 oval, compressed. Prothorax nearly twice as broad as long, 

 rather narrower at the apex than at the base, the sides 

 gently curved, the anterior angles nearly rectangular, the 

 base deeply impressed on either side for the reception of the 

 elytra; surface (<^) gently convex longitudinally, with a 

 slight transverse impression behind the apex, covered with 

 moderately close decumbent hairs, and scabrous with close, 

 elevated, confluent rugas, stronger at the sides, which are sub- 

 muricate, and absent over a shining central line, more or less 

 abbreviated behind and widened in front ; surface ( $ ) flatter, 

 muricate at anterior angles, the transverse striga of variable 

 length, situate before the middle, margined by a shining 

 rugosely punctured area. Scutellum very small, shining, 

 oblong. Elytra strongly rounded at the base, with irregular 

 sulci, coarsely and rugosely punctured, shallow before the 

 middle, deepened and shining posteriorly ; the first straight, 

 approximated to the second before the apex ; the third con- 

 fluent with the second just before the middle and imme- 

 diately behind with the fourth; the fifth confluent with the 

 fourth just after the base ; outer sulci subangulate inwards 

 after the base ; interstices convex, especially towards the 

 apex, rugose, granulate at the base, covered with short, rather 

 coarse, decumbent hairs, and divided by the confluent sulci, 

 so that the third interval has three, the fifth two, the seventh 

 one, subcallose enlargements on the disk. 



Underside and legs black, shortly hairy. 



Hob. Natal. 



My collection contains several specimens, and there are 

 others in that of the British Museum. The elaborate elytral 

 pattern gives the insect an appearance quite peculiar among 

 the Scolytidas.
