SERHICOENIA.

strongly angular at the sides, and there is a very slight impression on the basal lobe ; 

 the punctuation is close and fine, with a tendency to become confluent transversely, 

 except near the anterior angles, where it is obliquely confluent. The elytra are not 

 very convex, and are without costse. Each elytron has a green spot at the base, and a 

 small one on the shoulder ; a small round spot near the suture below the scutellum ; a 

 lunate spot just before the middle, touching the margin (nearly divided into two) ; and 

 two other spots rather behind the middle. The margins of the abdominal segments, 

 and the apex of the terminal one, are nearly black ; the latter with three acute teeth 

 (Tab. III. fig. 4 a). The head is concave in front, the upper part of the forehead 

 projecting, the lower edge of the projection straight.

This species varies from 5J-6-J lin. in length. The colour is generally uniform 

 brassy ; but the elytra are frequently darker, and sometimes quite deep purple. Some 

 examples have the thorax and abdomen less strongly sculptured than others. I cannot, 

 however, associate any of these differences with size, sex, or locality. The males, which 

 are rare, have the head golden-green ; and the abdomen deeply emarginate at the apex 

 instead of tridentate as in the female. 



I forwarded a female example to Prof. Westwood to compare with the type of 

 C. capitata in the Hopean Collection, and received the following note: — "The only 

 appreciable difference is that the face in our specimen is bright golden-green, with a 

 small fulvous-red spot with sharp margin occupying nearly the apex of the facial 

 triangle between the inner margin of the top of the eyes." 



The posterior spot on the elytra is sometimes (but rarely) divided into two. 



Specimens of this species were received from M. Salle with the name C. designata, 

 Thorns., attached ; and I believe this determination is correct, but M. Thomson 2 gives 

 ihe apex of the abdomen as bidentate instead of tridentate.
