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 

 and seventh striae also is a longitudinal suffused marking of fuscous, 

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

 Antennae filiform, robust, fuscous. Legs black.

 thorace quadrato, ad latera marginato, dentato, Icevi, impunctato, 

 rufo-ferrugineo ; elytris oblongis, subdepressis, striato-punctatis, 

 flavis, ad basin, ad suturam, et ad marginem (tenue), maculis

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



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

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

 low the base' of the antennas the surface is transversely depressed ; 

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

 above the base of the antennae 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. Antennae 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
