 Glyptoscelis dohrni Jacoby, 1900, Trans. Ent. Soc. London, p. 501. 



About 6 mm. in length, oblong oval, shining, elytra with faint 

 bronzy lustre, mostly lustrous black, antennae and legs reddish brown; 

 prothorax moderately finely and not very densely punctate with a 

 median bare line, elytra more coarsely but not much more densely 

 punctate with white appressed pubescence that on prothorax is 

 horizontally arranged, not so dense as to obscure surface on either 

 prothorax or elytra. 



Head shining, finely and sparsely punctate and lightly covered 

 with white pubescence, lower front with a median impunctate line, 

 labrum reddish brown, interocular space barely half width of head, 

 eyes with only slight emargination at antennal sockets. Antennae 

 short, extending below humeri, outer joints somewhat thickened, 

 seventh joint long, pale reddish brown. Prothorax moderately 

 convex, widest at base with only slightly curved sides, anterior angle 

 curved forward below eyes; punctation moderately dense and not 

 coarse, with a median bare line, a fine feathery pubescence arranged 

 horizontally from median line, not entirely obscuring shining black 

 surface. Scutellum black, with a few fine white hairs. Elytra not 

 depressed about scutellum, tapering to apex, which is pinched in but 

 not at all prolonged; intrahumeral depression faint, surface very 

 shiny with a faint bronzy lustre and moderately coarsely and not 

 densely punctate with a tendency to horizontal ridging; white pubes- 

 cence not dense or obscuring surface. Undersurface with thick 

 white pubescence, denser along sides, legs reddish brown. Length 

 6.2 mm.; width 3 mm. 



Type: In British Museum (Natural History), with 3 paratypes. 



Type-locality: Colombia, collected by Rehlke. 



Other locality: Colombia: Cartegena, Bolivar Pro v., on chaparral, 

 July 11, 1920, F. R. Mason. 



Remarks: The smaller size and stouter build as well as lack of any 

 prolongation at the apex of the elytra differentiate this from the 

 other two Colombian species, G. aeneipennis Baly and G. fascicularis 

 Baly. The aedeagus is unusual in shape with a tip that is narrowly
