le series of scabros'e punctures which are very distinct ; 

 iium deeply and closely punctured, and setulose ; median part 

 etasternum deeply punctate but having a narrow, longitudinal 

 )th space with a deeply impressed line in the centre ; anterior 

 not spinose inwardly at tip, apical spur straight, 

 le shape of the cephalic horn is nearly similar to that of 

 lastrucatus, but it is longer in proportion to the general size, 

 is more cylindrical. 

 le female is unknown, 

 mgth 7 mm. ; width 4 mm. 



lave seen only one male example, and it is quite possible that 

 ength of the cephalic horn may vary.

Onthophagus masteucatus, n. spec. 



irk bronze brown, shining, very pubescent on the upper side ; 

 5 straight, projecting at apex, clypeus semicircular but projecting 

 tly at apex, and with the edge slightly curved, frontal carina 

 ite, the whole head is covered with deep, rugose punctures ; 

 lorax marginate laterally but not along the base the median 

 of which is rounded, it is sub-canaliculate in the posterior dorsal 

 and is covered with very rough, closely set punctures, the sides 

 ilmost scrobiculate, and it is clothed with a dense, erect, slightly

 hly punctured ; metasternum scrobiculate laterally and deeply 

 tured in the median part ; anterior tibiae not spinose inwardly, 

 l1 spur nearly straight. 



ale : Clypeal carina not much raised ; between this carina and 

 '■ertex there is a long, sub-recumbent horn sub-cylindrical from 

 nedian to the apical part, reaching sometimes as far as the base 

 e pro thorax, and occasionally shorter ; the prothorax is sloping 

 le anterior part but not abruptly, and in the centre of this 

 dor part, which is only slightly impressed, there is a small 

 itudinal carina close to the apex. 



smale : Clypeal carina very well defined, vertex without any 

 iverse carina, apical part of prothorax with a very small, median 

 itudinal carina.
