cinum and C. eheninum) and more brilliancy." On tlie wHole I 

 am led to the conclusion, with a long series of specimens before- 

 me, that anthracinum, Macl., is a species which varies greatly in 

 size and colouring, and also a little in respect of the depth and 

 curvature of the frontal foveas.

 This insect is of very average proportions by measurement, 

 although the slightness of the curvature of the sides of the 

 elytra give it a rather elongate appearance. The sculpture of 

 the elytra, though very faint, is highly complicated, consisting 

 of a system of fine sparing puncturation rather unevenly dis- 

 tributed, thinly interspersed with short transverse scratches, 

 and traversed by about seven longitudinal rows of larger (but 

 not deeper) punctures placed close together in the rows, and 

 failing altogether near the base and apex. On the anterior 

 tibiae the exterior ridge seems to have only three teeth above 

 the apical large teeth, although (my specimen being an abraded 

 one) it is probable that the identification of some rudiment of 

 a fourth tooth is prevented merely by the loss of its seta. The 

 apex of the tooth next above the lame apical ones is scarcely 

 invisible when the tibiae is looked at from a point perpendicu- 

 larly above its upper face. The inferior ridge has seven well- 

 defined teeth commencing well back from the apex of the tibia. 

 The tibial structure does not seem to differ from that of 



* I continue to characterise the tibiae in the accustomed lanp;uage, but it 

 must be remembered that I mean by "bidentatae," having all the teeth of 

 the exterior ridge above the apical large ones (and by " tridentata" having all 

 hut the lowest of the same) invisible xohen the tibia is viewed from a point 

 perpendicularhj above its upper surface.
