obsolete ; clothed throughout with a fine silky flavous pubescence ; 

 flavo-ferrugineous ; at the humeral angles, along the margination, and 

 along the suture (more broadly at the apex), black ; between the fifth

 which does not extend either to the humeral angles or the apex. 

 Antenna; filiform, robust, fuscous. Legs black.

Long. corp. 3^ lin., lat. 1^ lin. 



Oblong-ovate, parallel, subdepressed, impubescent, testaceous, 

 shining. Head short, transverse, slightly and broadly produced ; be- 

 low the base of the antenna? the surface is transversely depressed ; 

 eyes tolerably prominent, situated nearly at the base of the head ; 

 above the base of the antenna? and between the eyes is a transverse 

 and also a longitudinal depression, which form together the character 

 of the letter T ; the surface impunctate, black. Thorax quadrate ; 

 the anterior angles subacute, the sides marginate and extending 

 laterally (a little in front of the middle) into a broad and distinct tooth- 

 like projection ; the surface smooth, impunctate, rufo-ferrugineous, 

 shining. Scutellum triangular, impunctate, black. Elytra oblong, 

 parallel, subdepressed, finely marked with rows of punctures in the 

 form of striae, impubescent, flavous ; at the base a broad and suffused 

 black band extends across the shoulders, and also along the suture 

 for about a third of its length : two circular spots are situated post- 

 medially near the margin, between the fourth and eighth rows of 

 punctures ; and at the apex two other oblong markings (extending 

 in an oblique direction) are separated from the margination, but 

 join the suture ; these four spots (with a narrow margin along the 

 line of margination of the sides, and another, more distinct, at the 

 suture) are fuscous-black. Antennas robust, dark fuscous. Legs : 

 the femora flavo-ferrugineous (the apex and upper part of the femora 

 being suffused with piceous) ; the tibiae and tarsi piceous ; on the 

 outer longitudinal margins of the posterior tibiae, near the insertion of
