granular, clothed with llavescent hairs ; antennae flavous ; prothorax 

 broad, marginate laterall}- and in front but not along the l)ase the 

 median part of which is depressed and projects as a broad triangle, 

 it is moderately closely punctate, but the punctuation varies in the 

 sex, the median supra-basal part, however, is smooth in both ; elytra 

 broadly ampliate at base, and gradually attenuate from about the; 

 median part, the striae are very shallow, but somewhat broad and 

 not geminate, the intervals are covered with very closely set seti- 

 gerous punctures, the second interval is twice as broad as the third, 

 which is also narrower than the fourth, the humeral callus is very 

 distinct, and the third and fifth intervals are raised ; pygidium very 

 closely punctured, pubescent ; median parts of metasternum smooth 

 and having a faint longitudinal impressed line ; apical spur of 

 anterior tibiae curved inwardly at tip. 



Male : Clypeus rounded in front, no trace of frontal carina in the 

 large development, but it can be noticed in less developed males, 

 horn on the vertex upright for half the length, and from there 

 slightly curved backwards and reaching a length of 12 mm. in the 

 curve ; prothorax with a deep excavation on each side of the anterior 

 part, and having in front of each excavation a compressed triangular 

 tooth curving backwards, and at the apex of the anterior declivous 

 part two small tubercles, the posterior part is broadly sulcate as far 

 as the basal part, and the excavations as well as the median part 

 of the disk are smooth, in the smaller development the cephalic 

 liorn is nearly vertical and only 3| mm. long, the anterior part of 

 the prothorax is only slightly hollowed, but the two anterior teeth 

 and the two median tubercles are very w^ell defined ; inner part 

 of anterior tibiae produced into a distinct, sub-diagonal spine at 

 apex. 



Female : Clypeus slightly acuminate at tip ; frontal carina very 

 distinct and arcuate, frontal part with a median high carina conical 

 at each end ; prothorax covered with closely set piuictures except in 

 the supra-basal median part, impressed on each side of the anterior 

 median part, the two impressions are divided by a cuneiform, ver- 

 tical lobate process, and have on the side a short, vertical, carinate 

 tubercle, the median part of the disk has only an impressed line in 

 the posterior part.
