rather strong ridge from the humerus obliquely to the mid- 

 dle, where it ends in a sharp tubercle near the suture. This 

 tubercle has a costiform continuation parallel with the suture 

 to the apex. The punctuation is fine and the depressed areas 

 have a tendency to rufous coloring which is especially marked 

 back of the scutel as in scortillum Lac. ; pygidium coarsely 

 and confluently punctate. 



The one specimen before me was in the first Jacoby col" 

 lection marked pelhuida Klug. The excavate front is dif- 

 ferent from any other form known to me. Coelocephala Lac. 

 has an excavate head, and schottii Koll. has its vertex exca- 

 vate, but neither approaches the present form. I place this 

 species for the present in Lacordaire's 16th group. 



Clilaniys jatahyeiisi.s nov. sp. Stout, head and thorax yellow 

 (the latter sometimes spotted with black), the elytra velvety black 

 with a silken gloss, having in certain side lights a greenish or purplish 

 tinge, pygidium and abdomen yellow, rest of the body below and 

 legs black, the latter obsoletely yellow spotted on the thighs ; pros- 

 ternum punctured, abruptly narrowed at the middle to a thin edge; 

 length 4^-5 mm. 



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



Head thickly punctate, antennae short, 2d joint obconic, 

 3d and 4th about equal and cylindrical, very gradually en- 

 larged, beginning with 5th, last five joints dark, thoracic 

 hump very moderate, declivous behind, the edge forming a 

 feeble crest which shows on its edge the beginnings of about 

 three obsolete tubercles, like echinata Klug. only very feeble, 

 the median sulcus is very feeble and becomes obsolete on 

 the front ; the basal sulcus is feeble and the lateral tubercle 

 obsolete, the punctuation is almost uniform and dense over 

 the entire surface, the thoracic spots vary in the two speci- 

 mens, the cf has the following black spots, declivity of the 

 hump on each side of the sulcus, triangular in shape, two 

 series of three round dots each placed transversely, the mid- 

 dle one on the line of the sulcus and the rear one connected 

 by a narrow line with the elytra ; the 9 shows only obsolete 

 traces of about three or four of the round dots, the usual 

 elytral lines are broken into a set of medium tubercles and
