new Species of Ilistericlaj. i') 



trntits anil colomhi'te, Lew. (described below). 7'. unituhercn- 

 lutus is peculiar in haviii<; a median furrow in the ineso- 

 Bternum, which is iinmai-f^inate laterally. In Ilololepta the 

 ocular tubercle is h'ss perpendicular than in Tri/pancvusj as 

 nii;:ht be expected from their depressed form, 



J/ah. Bolivia. 



I have only one male example, but I have a<lopted a trivial 

 name su^ijested by Ilerr J. Hchmidt some years ago, and his 

 collection doubtless contains other specimens. 



Trypanaius Colombia, sp. n. 



cJ . Cyliiidricus, nigrer, iiitidus ; fronte baud carinata, bisulcata, 

 medio longitudinaliter impressa, rostro acute reflexo ; pronoto 

 raargine antice fortiter punctate, unitubcrculato : el} tris sparse 

 putictulatis ; pygidio sat dense punctate ; prosterno antice acuto, 

 immarginato ; tibiis anticis S-dentatis. 



L. 6:J-0i mra. 



Cylindrical, somewhat robust, black and sinning ; the head, 

 foiehead bisulcate, sulci narrow and shallow anteriorly, 

 wideninf; and deepening between the eyes, the median carina 

 in the allied species is represented by a longitudinal shallow 

 canaliculation, the ocular tubercles are somewhat acute and 

 the apex of the rostrum is pointed and markedly reflexed ; 

 the tliorax is densely and coarsely punctured along the 

 anterior part, the anterior angles are not impiessed, but they 

 have a marginal carina, in the middle behind the neck there 

 is a single tubercle, behind t!.e tubercle the thorax generally 

 is finely and not closely punctulate, but longitudinally the 

 punctures are closer and larger in the middle; the elytra aie 

 also tinely punctulate generally, but along t^ie sutural and 

 apical margins the punctures are larger and (especially at the 

 apex) closer together; the pygidia are lather closely punc- 

 tured; the prosternum, keel immarginate, punctured, and 

 gradually narrowed to the apex ; the mesosternum is also 

 immarginate ; the anterior tibiae 5-dentate. 



The female : the head is opaque and finely punctulate, 

 rostrum very obtuse ; the thorax clearly and evenly punctured 

 throughout, points generally larger than those of the male ; 

 the prosternum, keel nearly smooth, somewhat obtuse at the 

 apex, and distinctly marginate ; the metasternum is canalicu- 

 late and its basal iialf strongly punctate. 



Tiiis is the most robust species known with an ocular 

 tubercle. 



JJah. Colombia.
