on either side, the medial lobe acute ; above subconic, 

 cylindrical at the apex, the entire outer limb bordered 

 with a single row of deep punctures ; surface sparingly 

 impressed here and there with coarse punctures, finer and 

 more remote in the middle of the disk ; on either side 

 near the lateral margin is an ill-defined transverse groove ; 

 basal margin very narrowly edged with black. Scutellum 

 narrowly ovate, attenuated at the base, rufo-fulvous, edged 

 with black. Elytra oblong, not broader than the thorax ; 

 convex, strongly punctate-striate, striae moderately sulcate, 

 the seventh stria from the suture commencing below the 

 humeral callus, oblique and joining the sixth stria just 

 below its middle ; fifth and eighth strias abbreviated some 

 distance below the middle of the elytron ; interspaces 

 smooth and shining, moderately convex, more strongly so 

 on the outer border.

Ovatus, valde convexus, niger, nitidus, thorace im- 

 punctato, facie inferiori, antennarum basi pedibusqu 

 rufo-fiilvis ; elytris regulariter punctato-striatis, interspatii

Head rather coarsely punctured ; vertex black ; eyes 

 large, nearly contiguous at the apices, being only separated 

 by a very narrow line ; antennse two-thirds the length of 

 the body, six outer joints slightly thickened; six lower 

 ones pale rufous, the rest black. Thorax nearly twice as 

 broad at the base as long ; sides rounded and converging 

 from base to apex ; basal lobe acute ; above convex, 

 cylindrical at the apex, the apical margin bordered by a 

 deep transverse sulcation; surface shining, impunctate, 

 the basal margin narrowly edged with piceous. Scutellum 

 narrowly lanceolate-ovate. Elytra oblong, convex, not 

 thickened behind the scutellum, strongly and regularly 

 punctate-striate ; interspaces shining, impunctate, convex, 

 those over the outer margin subcostate. Prosternum slightly 

 broader than long, its apex produced, obliquely deflexed, 

 its hinder margin slightly concave-emarginate. Meta- 

 sternum and abdomen black. 



Coenobius discoidalis. 



Breviter ovatus, valde convexus, niger, nitidus, antennis
