angulate thorax as described by Mr. Jacoby. The angulation as 
well as colour easily indicate this form.

abdomen rufous; legs rufous, with apex of tibia and tarsi dark 
cyaneous; body above shining, chestnut brown, overlaid with

Type, ¢, Mecas, Ecuador. 
Length, 4 mm. 
Head finely and rather sparsely punctulate, with well- 
marked transverse and longitudinal impressions; thorax obso- 
letely collared in front, sparsely, unevenly, mixed punctulate ; 
elytra with obsolete transverse depression coarsely punctate, 
semiseriate on the disc, subcostate at the base and strongly 
costate at the apex, more or less rugose at the sides; thorax and 
elytra with narrow reflexed margins, these and the punctures 
obsoletely metallic green. 
Rhabdopterus aciculatus, sp. nov. 
Large, stout. Below with legs very dark brown; breast and
