species as European, of which ten are his own naming ; nine of these 

 have never been described, and, except that the types or the drawings 

 are in the possession of MM. Lethieny and Puton, they might as 

 well never have been named. 



The following are the principal characters by which the genus 

 may be known : — 



Head — crown slightly convex ; anterior margin rounded, angle 

 obtuse ; distance between the inner margin of the eyes at the base 

 twice or more than twice the length down the centre ; basal margin 

 concave, ^i/es moderate, outer margin in a line with the lateral 

 margin of the pronotum. Ocelli minute, placed on the anterior margin 

 near to each eye. Face convex. Clypeus reaching to the lower mar- 

 gin. ClieeTcs wider than long, with a longitudinal channel in a line 

 with the lower angle of the eye : lo7'(S somewhat lozenge-shaped, the 

 outer margin rounded. 



Thorax — pronotum transverse, sub-hexagonal ; anterior margin 

 convex ; lateral margins rounded ; posterior margin concave. Scutel- 

 lum triangular, apex acute. Elytra — clavus : axillary nerve joined to 

 the central nerve by a transverse nerve springing from the centre of 

 the former ; central nerve and claval suture united at irregular in- 

 tenals by 3-4 transverse nerves. Cerium : ante-apical areas divided 

 here and there by transverse nerves. 



Abdomen : genital valve short, projecting but a little way beyond 

 the margin of the last abdominal segment ; genital plates elongate, 

 somewhat parabolic. 



Crown somewhat bone-wliitc' ; cxtrenio anterior margin with four black spots, best 

 visible from in front, and a black patch next each eye, its inner margin half en- 

 circling the ocellus ; in the middle, two black spots about equidistant from each 

 other and the eyes, and posteriorly a smaller spot, sometimes obsolete, near 

 each eye. Face black, with about seven short, transverse, yellow streaks on 

 each side, and a narrow, longitudinal, central line joined to a broad transverse 

 band before the apex, also yellow. Clypeus yellow, with a black, longitudinal, 

 central line widened towards the apes ; /ortE yellow, margined with black, except 

 at the apex next the clypeus. Elytra black, longer than the abdomen. Clavus : 

 suture and inner marginal nerve testaceous ; at the apex of the central nerve a 

 large, white, somewhat semi-ovate patch, in which is a sometimes divided black 

 streak next the claval suture ; along the inner margin between the base and the 

 apex of the 1st nerve, three or four white spots ; disc between the nerves re- 

 ticulated with bro^^"n. Corium : costal nerve testaceous-white; 1st and 2nd 

 transverse nerves white, the colour on the former extending for a little way iip 

 and down the longitudinal nerves forming an H-shaped character; costal margin 

 with a white patch opposite the two transverse nerves, in the former generally
