278 Mr. H. W. Bates' supplement to the 



head and more deeply impressed frontal furrows ; the 

 latter curve inwardly behind, and terminate before 

 reaching the crown ; they are sharply and obliquely 

 cut, and separated from the fine sculptured line near 

 the eyes by a wheal, moderately elevated. The speci- 

 men figured is a variety, in which the elytral spot 

 extends to the apex.

Extremely near C. fidvipennis, which, if I have deter- 

 mined the species rightly, is found at Hong-Kong, and 

 not in Celebes, as stated by Chaudoir. It differs, how- 

 ever, a little in form, the head in both sexes being more 

 straightly narrowed, and appearing longer behind the 

 eyes. The margins of the pronotum also have only a 

 row of large punctures, few in number, instead of being 

 thickly punctured, and the thorax seems to taper more 

 gradually in front. 



Chaudoir gives no reason for placing his species in 

 Odacantha rather than in Casnonia. It is certainly 

 much more nearly related to the group of Casnonia of 

 which C. fuscipennis is the type, than to Odacantha 

 mclanura. There appears, however, to be no structural 

 differences between the two genera, the shorter and more 

 oblong form of the thorax and slightly thicker palpi in 

 Odacantha being the only perceptible difference.
