tively, and an apical transverse band of the same colour emitting 

 often a longitudmal band on the fifth interval ; genjB very small 

 triangular, clypeus short, rounded laterally for a short distance! 

 then acummate diagonally, truncate, very slightly emarginate 

 at tip and with the margin slightly reflexed ; in the^centre of the 

 head there is a laminate, sub-hori/ontal carina extending from one 

 side to the other, and a clypeal one equi-distant from the apex of 

 the elypeus and from the, frontal carina and connected ^vith it by a 

 median longitudinal ridge, the anterior part of the head is sparsely, 

 and the posterior one closely punctulate ; prothorax slightly convex 

 not rounded laterally at middle, maiginate in front and on the sides,' 

 but not distinctly along the base which is rounded, it is covered 

 with not quite contiguous round punctures, and has no lon-i- 

 tudinal median impression; elytra oblongo-ovate, finely and narrowly 

 geminato-striate with the intervals plane and filled with numerous 

 very briefly setigerous rugose punctures, scrobiculate and confluent 

 m the anterior part, and having thus a rough coriaceous appearance ; 

 pygidmm covered with very closely set round punctures ; meta- 

 sternum closely and equally punctured, median impressed line 

 very distinct for the greater part of the length; anterior tibia, 

 non-spmose inwardly at tip, apical spur moderately slender, nearly 

 straight The two sexes are usually alike, but one of my males has 

 at the base of the head a minute tubercle. 

 Length 6-7 mm. ; width 4-4i mm.

Generic characters of Onthopha^jns, but it ditiers in the shape of the 

 an eruor tibia, which may be dentate outwardly in the male or not, 

 bu they are dilated and truncate at tip, the truncate part is laminate 

 and turned briefly downward, the apical outer part is rounded, and 



he spur IS very small. This difference in the shape of the anterior 

 tibiae seems to me to be the only one that mihtates in favour of 



he retention of the genus ; the prosternal differences mentioned 

 by Hai-old and others (Coleopt., Heft, ii., 1867, p. 1) and Jekel 

 (Rev. et Mag. d. Zool. (xxiii., 1872, p. 405) are partly common to 

 many species of Onthopha,jus.
