STRONGYLIUM PERTURBATOR, n. sp. 



Bronze-black, the elytra with a more metallic sheen than the rest 

 of the body ; anterior part of the head closely but roughly punctate, 

 posterior one with deeper and more scrobiculate punctures right to 

 the base, frontal arcuate sulcus distinct, but not deep ; prothorax 

 slightly rounded laterally in the anterior part and only very slightly 

 sinuate in the posterior, somewhat plane on the disk, and convex 

 laterally, covered with nearly contiguous punctures separated by 

 rugose irregular intervals, lateral margin very slender, basal one 

 thick, rounded ; scutellum with a few tine, scattered punctures ; 

 elytra cylindrical, deeply punctato-striate, intervals convex, smooth ; 

 abdomen finely yet deeply, but not closely punctate ; legs and 

 sternum deeply punctured; antennae barely reaching the base of 

 the prothorax, fourth joint as long as the third and wider at the 

 top, fifth, sixth, seventh, and eighth bluntly triangular and as broad 

 at apex as the ninth, which is more transverse, tenth narrower than 

 the ninth by nearly one-half, but equally long ; the eleventh joint 

 is missing in my example. 



Length 17-21 mm. ; width 5^-7 mm. 



Not unlike S. ceratum, Makl, but the antennae are not as long 

 and the joints are shorter and wider ; the colour is also much darker.
