A pair of rather poorly preserved elytra, parted at the tip, and showing 

 between and through them the outlines of the abdominal segments represents 

 a species of Chrysomelidse, which appears to be most nearly allied to the 

 genus in which I have placed it and to be about the form of, and a little 

 smaller than, G. maritiraa LeC The elytra are uniformly piceous throughout, 

 showing no marks of lighter-colored borders ; there are faint indications of 

 one or two marginal impressed lines in their outer half, and the whole sur- 

 face seems to have been very minutely punctate, more faintly and finely 

 than in the existing species mentioned. The abdomen is very broadly and 

 very regularly rounded, subovate, and at least five segments of similar 

 length can be determined. 



Breadth of the pair of elytra at base, 3.7.5""™; length of elytra, 5.5°"° ; 

 breadth of abdomen, 3.25°" ; length of penultimate segment, 0.4°°'.

This species is fairly represented by a pair of .specimens with their 

 reverses. One pair exhibits the front, and by the drooping of the abdo- 

 men the under surface of the insect with expanded elytra (one of them 

 curiously foreshortened), the other the under surface only. The insect is 

 broadly oval, and, except in being much stouter, closely resembles C. ven- 

 ustus Fabr., with which it agrees in size. The thorax, as seen on a front 

 view, is arched, and the proportion of the head to the thorax is as in the 

 recent species mentioned. The elytra, which are the parts best preserved.
