ETJPHENGES. 25 



lens to be impunctate ; pale testaceous, with six large and distinctly 

 denned m/o-testaceous spots, arranged at equal distances one from 

 the other and midway between the suture and margination two 

 (circular) at the base, two larger (and approaching the form of a 

 parallelogram) at the middle, and two (subcircular) at the apex ; 

 margination of the elytra rufo-flavous ; surface obsoletely pubescent. 

 Antennas filiform, long, tolerably robust, and slightly tapering to- 

 wards the apex; the first joint is much broader than the others, 

 curved outwards and dilated at the extremity ; flavous, the rest rufo- 

 fuscous, with the three terminal joints rufo-testaceous. Legs large 

 (compared with the magnitude of the body) ; the tibiae, which are 

 singularly robust, are all distinctly curved or bent inwards ; femora 

 testaceous, tibise and tarsi rufo-ftiscous. 



A single specimen was captured by Mr. Bates in the district of the 

 Amazon, and is in that gentleman's cabinet.
