DOLICHASPIS, n. g. 



From Mecasjns differs by the more elongated and 

 much smoother scutellum ; the femora all unarmed 

 underneath ; the mesosternal process flat below, some- 

 what truncate and subvertical in front.

Chalybeato-violacea vel viridi-cyanea ; prothoracis disco subti- 

 liter atro-velutmo ; scutello longissimo (5^ — 6 mm.), minute 

 sparsissimeque punctulato ; elytris miniitissime creberrimeque 

 punctulatis et tenuiter velutinis, versus apicem glabris et sparsim 

 punctulatis ; corpore subtus chalybeato, subnitido ; lateribus pec- 

 toris abdomiuisque siibtilissime argenteo-sericeis ; anteunis nigris, 

 dimidium elytrorum paullo excedentibus. Long. 35 — 86 mm. 



Hah. Angola. 



Prothorax strongly though somewhat obtusely tubercled on eacli 

 side ; the disk with a faint velvety black pile, with the median line 

 glabrous. Scutellum very long, very sparsely puuctulate, and 

 without transverse ridges. Elytra very minutely and closely 

 punctulate on those parts covered by the faint velvety pile ; 

 towards the apex and on a narrow space along the middle of each, 

 glabrous and sparsely punctulate. Legs and underside of the body 

 steel blue, sub-nitid ; the tarsi above with a shining grey pile. 

 Prosternal process rather broader towards the middle of its length, 

 strongly arched and subvertical behind. Antennae scarcely differing 

 in the two sexes ; reaching to about the apical third of the elytra 

 in the male. 



Two specimens, which appear to be male and female, 

 in the Brit. Museum collection. In the male the sixth 

 ventral segment is scarcely visible, and the apex of the 

 fifth is slightly sinuately emarginate ; in the female the 

 fifth segment is rounded at the apex.
