This insect is larger than L. pudens, Lacord., and distinguished by the red base of 

 the femora, the distinct elevation of the base of the elytra, and the red basal portion of 

 the head.

58. Lema bipustulata. (Tab. II. fig. 10.) 



Oblong-parallel, violaceous, below black; base of the head with two rufous spots, smooth; elytra deeply 

 punctate-striate ; base of the femora rufous. 



Length 2 lines. 



Head smooth, shining ; antennae slender, filiform, as long as half the body ; thorax a little broader than long, 

 the anterior angles subacute, sides very moderately constricted, the basal transverse groove distinct and 

 sinuate at the sides, surface impunctate ; elytra moderately deeply punctured, their base distinctly 

 elevated and deeply depressed below the elevation, the punctured strise much less deep towards the apex, 

 the latter not costate except near the lateral margin, the ninth strise interrupted ; underside black, finely 

 pubescent, base of the femora rufous. 



Eab. Costa Eica (v. Patten). 



The differences between this insect and L. maculifrons consist in the larger size of the 

 former, its black antennae, the totally impunctate and not rugose head, and the colour 

 of the base of the femora ; the transverse basal depression of the elytra, although deep, 

 is not so strong as in L. maculifrons ; and the thorax shows no traces of punctuation.
