the middle, lateral tubercle well marked, elytra slightly constricted at 

 middle, intervals thickly punctate, each elytron with about fourteen 

 spinous tubercles; pygidium quadrate, impressed, tricarinate, the side 

 carinae arcuate and broken ; presternum rather narrow in front, 

 slowly increased to an obtuse point, so as to appear sulcate, all the 

 tibiae dentate within ; length 4-41 mm. 



Type. — cf ; Jatahy, Goyaz ; one cf, two 9 specimens. 



Head rather sparsely punctate, antennae stout, 2d joint 

 obconic trigonate, 3d joint shorter than 2d, trigonate, closely 

 applied to the next, 4-11 strongly transverse, thorax thickly 

 finely punctulate, irrorated here and there with darker 

 clouds, noticeably so on either side of the median sulcus 

 behind, basal sulcus well marked by a deep and rather 

 smooth groove. The most noticeable tubercles of the hump 

 are four placed anteriorly near the median sulcus, one above 

 the other on the anterior declivity : the median sulcus behind 

 these is edged with a uniform row of small smooth tubercles ; 

 anteriorly at the side is a costiform tubercle (seen from 

 behind); of the elytral tuberosities there are on each elytra 

 two at the base, a sutural and median, then there are a series 

 of five much smaller elevations occupying the median belt, 

 four of which are arranged in a transverse line in the mid- 

 dle ; the apical portion is occupied by seven or eight strong 

 spinous tubercles, one being sutural post median and a group 

 of three arranged triangularly at the apex, these last being 

 the longest of all. The usual elytral lines are faintly trace- 

 able between the tubercles, suture finely dentate, abdomen 

 coarsely punctate, sides obsoletely bituberculate. 



I place this species near schottii Lac. The dentate tibiae 

 easily separate it. 



Clilamys siiinielirastii nov sp. Chestnut brown with a red- 

 dish tinge to the thorax, the punctuation slightly darker, especially on 

 the elytra, antennae dark at tip, thorax with a strong conical rounded 

 hump (somewhat like natteri \Lo\\.)\ sulcus entire though not deep ; 

 elytra impressed with rather large brown punctures, the usual lines 

 almost obliterated, the humeral showing best, and ending in a small 

 costiform tubercle ; the other elevations are small, the scutellar region 

 is depressed and darker in color ; suture dentate in almost its whole 

 length ; carina of pygidium obsolete ; presternum obliquely narrowed
