IIVI'OLAMPSIS. 241 



an appearance of prominence to the surface near the scutellum. 

 Antenna 1 , robust, incrassated towards the middle and apex ; the third 

 and fourth joints being of nearly equal length, longer than the others, 

 and attenuated ; the fifth to the eleventh short, and gradually di- 

 lated : in colour, the first and second are rufo-fuscous, the fifth to the 

 seventh fuscous, the third, fourth, and eighth to eleventh testaceous. 

 Legs flavous throughout, the globular inflation of the posterior claw 

 being brightly rufous.

Long. corp. 1| lin., lat. |- lin. 



Ovate, broad, robust, impubescent, piceous. Head short, slightly 

 produced in front ; below the base of the antennas is a transverse, 

 depressed, equate plane ; the eyes are subprominent, extending late- 

 rally beyond the anterior angles of the thorax ; the surface is gra- 

 nulated. Thorax transverse (somewhat quadrate), slightly constricted 

 towards the base ; the anterior angles subacute and depressed ; the 

 sides are marginate ; near the anterior margin (and also more 

 broadly at the base) is a transverse depression, most distinct near to 

 the anterior angles ; the surface is thickly and very finely punctate. 

 Scutellum triangular. Elytra broad, robust, coarsely and deeply 

 punctate-striate ; a transverse antemedial depression extends ob- 

 liquely upwards towards the humeral angles ; the surface is piceous, 

 at the apex broadly (and also at the margin) rufo-ferrugineous: a short 

 transverse line extends from the sixth stria postmedially to the 

 marginatum (in colour also rivfo-ferrugineous) ; this line is some- 

 times interrupted and assumes the form of a spot. Antenna; filiform, 

 rufo-ferrugineous, the seventh and eighth joints being rufo-piceous. 

 Legs rufo-ferrugineous, the posterior femora being suffused with 

 piceous. 



This obscure little species is separated from most of its congeners 

 by the transverse anterior depression of its thorax and the rufous 

 apex of its elytra. 



From the neighboxirhood of Rio Janeiro. Taken by the late 

 Mr. Squire.
