12 COLEOPTERA CHLAMYDAE. 



with dark rufous clouds on either side of the sulcus behind, 

 this color continuing more or less toward the front and show- 

 ing several small spots at the side, of which the one at the 

 side of the hump behind the middle is the most noticeable. 

 The elytra are almost uniformly (except apex) rich dark 

 reddish, the elevated lines showing as strong costae, the 

 sutural and median being the most obvious casually and the 

 latter extending nearly to the apex, and showing at its base 

 a sharp prominent tubercle ; the reticulation is everywhere 

 plain and becomes coarser at the apex. Suture is dentate, 

 the sides of the body are nearly parallel, and show only a 

 very faint compression behind the shoulders. The body 

 below is very finely punctured in great contrast to the upper 

 surface. 



Should be placed near lacordairei Jac, which it resembles 

 in shape, but the dark color which shows on the elytra of 

 that species as a spotted band entirely suffuses the elytra in 

 gounellei. 



Clilaiiiys lutescens nov. sp. Stout, quadrate, luteous, rear of 

 the thorax clouded with rufous-purple, and elytra with a common 

 median rufous-purple spot and a vague cloud on either side, thoracic 

 hump rounded, convex in front, declivous behind, with a row of about 

 six tubercles set in a curve on the top edge of the declivity ; median 

 sulcus behind wide and shallow, obsolete in front, about eleven or 

 twelve tubercles on each elytron, the most prominent being a median 

 subbasal and a sutural apical ; suture dentate ; presternum abruptly 

 narrowed to about the middle, then narrow and parallel and thickly 

 margined to obtuse end ; length 5.5 mm. 



Type. — 9: J atahy Goyaz, Brazil ; two 9 specimens. 



Head slightly convex, thickly punctate, antennae, rather 

 long, 2d joint obconic, 3d and 4th elongate, slightly dilated, 

 5-11 transverse, thorax very thickly punctate with a well 

 defined obtuse lateral tubercle, separated from the hump by 

 the basal sulcus, which is fairly limited, and ends on the 

 anterior face in a deep depression. The hump is shaped as 

 in deyrollei Jac. and ker^nes Lac. et a I., i. e., wide, convex in 

 front, moderately declivous behind with a row of tubercles 

 on the upper edge. The median sulcus is wide behind, 

 feebly limited on the sides and passes between the two apical
