General: Body stout, 1.6 times longer than wide; dorsal surface 

 rather shining, lacking pubescence; ventral sm"face with very short 

 and sparse, yellowish pubescence. 



Head: Dull orange with yellowish near eyes and on clypeus to dull 

 orange throughout; front with moderate-sized punctures; clypeus 

 rather sharply delimited, more or less concave, distinctly broadest 

 apicaUy. Antennae over two-thirds length of body in male, or over 

 half length of body in female; usually with basal five segments dull 

 orange, apical segments brown to dark brown. 



Pronotum: Dull orange throughout, sometimes lighter or yellowish 

 as follows: at base in two vague oblique spots, narrowly at side, 

 narrowly at apex. Punctation dual, smaller punctm-es minute, moder- 

 ate in density, indistinct, larger punctures moderate in size and 

 density, rather coarse, longitudinally elongate. 



Elytra: Dull orange throughout, two intervals at side of each elytron 

 more or less yellowish; humerus usually dark reddish; punctures a 

 little darker than remanider; with indistinct to obsolete indications of 

 darker longitudinal stripes on intervals two, three, six, seven, and 

 eight. Each elytron with nine rows of moderate-sized, rather close 

 punctures; rows six and seven rather to distinctly confused; punctures 

 smaller toward apex; inner and outer rows distinct at apex and nearly 

 or quite meeting.
