182 NORTHERN ZOOLOGY. 



DESCRIPTION. 



Body black, rather slender, slightly punctured, thinly coated with decumbent yellow hairs. An- 

 tenna; shorter than the body, fifth joint scarcely longer than the fourth : prothorax between bell- 

 shaped and a truncated cone, a little constricted in the middle, fringed with yellow hairs anteriorly 

 and posteriorly : scutellum triangular : elytra testaceous, yellow at the base, and with three yellow 

 bands, the first interrupted ; oblique sinus at the apex not so deep as in the two preceding species : 

 legs testaceous ; abdomen of a deeper colour ; and segments scarcely emarginate. 



This species differs in habit from the two preceding ones, it is narrower in proportion, and comes 

 nearer to L. quadrifasciata, but the posterior angles of the prothorax, though acute, are not so 

 prominent, it belongs however to the same subdivision, with the last mentioned insect.
