 Ohio, Schaum. This species has the same form as L. symmetricus, but the lateral 

 thoracic spine is perceptibly in front of the base. The spots of the elytra are nearly 

 similar, viz. two small subsutural ones near the base, a sublateral one just before the 

 middle, connected with a large transverse angulated band reaching nearly to the 

 suture, and finally three subapical spots arranged so as to form with those of the other 

 elytra a portion of a circle.

antrorsum angustato, lateribus rectis spina in basi ipsa sita, eljtris parce punctatis, maculo basali, alteris 

 marginalibus confluentibus, fasciaque lata angulata paulo pone medium obscuris. Long. •26.

not quite reach the suture ; the femora and tips of the tibiae are slightly fuscous. 



A variety from Mr. Wapler of New Orleans is much paler colored ; the thorax with 



four irregular vittae, and the angulated band of the elytra broken into 3 linear spots • 



the extreme apex of the femora and tibiae is black. 



9. L. BiGUTTATUS, elongatus minus depressus, punctatus, testaceus, sordide pubescens, thorace ante basin 



utrinque acute spinoso, lateribus ante spinam subrotundatis, elytris pone medium utrinque macula obliqua 

 nigra signatis, basi linea brevi longitudinal! elevata j femoribus omnibus modice clavatis. Long. -33. 

 New York, Guex. By its slender form and long antennae, as well as by the form 



of the mesosternum, this species belongs to the present division ; by its clavate femora 



it established a passage to the next division. 



C Corpus subelongatum, femoribus omnibus clavatis, elytris apice subtruncatis, 



mesosternum truncatum.
