broad, narrowed bcliind the front, on each side very 

 oblique, the punctuation similar to that of the head ; the 

 extreme base with four small foveas, the middle with a short 

 and excessively fine channel. Elytra brighter red than the 

 head and thorax, distinctly lon<>;cr than the thorax, closely 

 punctured, each with three series of punctures ; one along 

 the suture, two along the middle, these rows not reaching 

 to the apex. Hind body very densely and finely punc- 

 tured, quite opaque. Legs reddish. Front tarsi short, 

 moderately dilated. 



Ega and Tapajos ; two individuals. 



Ohs. — The structure of the 4th joint of the middle and 

 hind tarsi is ])cculiar in this sj)ecics ; though narrow, this 

 joint is on the u})i)er side dee})ly Ijilobed. 1 do not know 

 the sex of my individuals, but I think them to be males,

 very indistinct. Elytra fiiu^ly and indistinctly, not very 

 closely ]Muu'tu red ; a little shining, with traces of a sutnral

 dilated. 



In the male the ventral plate of the 7th segment of the 

 liiTid body is slightly emarginate in the middle at the

()//s. — This species is rather smaller than L. discedens,

 of" sculpture, which ri'adily enough distinguish it, it has
