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

 often a longitudinal band on the fifth interval ; genae very small, 

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

 then acuminate diagonally, truncate, very slightly emarginate 

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

 head there is a laminate, sub-horizontal carina extending from one 

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

 the clypeus and from the frontal carina and connected with 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, marginate 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 longi- 

 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 

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

 pygidium 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 tibiaB 

 non-spinose 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 4-4^ mm.

Generic characters of OntJiopJiagus, but it differs in the shape of the 

 anterior tibiae, which" may be dentate outwardly in the male or not, 

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

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

 the spur is very small. This difference in the shape of the anterior 

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

 the retention of the genus ; the prosternal differences mentioned 

 by Harold 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 Onthopliafjus.
