SEKRICOENIA. 183 



sufficiently definite to enable me to decide: — " Prothorax lateribus subhexagonus." 

 " Corpus subtus tenuissime et sparsim punctatum." " Abdominis segmentum ultimum 

 apice 3-spinosum." " Tres-voisin du C. cyanitarsis, mais le contour lateral du prothorax 

 est autre ; il est non sinue au milieu et retreci en arriere." " La punctuation en dessous 

 est plus forte." 



The apex of the abdomen is trispinose.

This species should be placed at the head of the genus, or it might with equal pro- 

 priety be placed at the end of Colobogaster. It differs from all its allies in the compa- 

 ratively elongate thorax. The head is closely and strongly punctured at the lower part 

 of the face, less closely at the upper part. The thorax is convex, much narrower than 

 the elytra, about one-third broader than long, not much narrowed in front, gently 

 sinuate at the sides at the middle, slightly wider at the posterior angles, which descend 

 perpendicularly on to the elytra ; there is a very slight longitudinal median impression ; 

 the median basal lobe is narrow. The elytra are formed very much as in Colobogaster 

 chlorosticta, but are rather more narrowed at the apex ; the suture for one-third its 

 length from the base is green ; each elytron has a bluish-green band at the base and 

 an oblique band before the middle, the latter extending from the margin to about the 

 middle of the elytron, where it is dilated, the surface here being impressed and more 

 strongly punctured ; there is a small spot close to the suture at the apex of the sutural 

 stripe ; behind the middle, near the side, there is a deep round fovea, with a short trans- 

 verse spot crossing it, and between this and the suture is another spot ; the apical 

 margin is also blue-green. The abdomen has the apical, segment truncated, with the 

 outer angles of the truncature dentiform, the middle part of the apical margin produced 

 a trifle beyond the level of the outer angles.
