sides of the incision being parallel. In C. occulta there is a 

 smaller incision in the form of an acute triangle. 



I have not seen the male of either of these species.

Chrysodema Broivnii, n. sp. 



C. smaragdulce approximans, aeneo-viridis, nitida ; thorace disco 

 utrinque fovea sat magna crebre punctulata impresso, lateribus 

 fortiter punctatis ; elytris costis interruptis cyaneis parum elevatis, 

 interstitiis fortiter punctatis viridi-auratis. plagisque nonnullis 

 igneo-cupreis ornatis.

Very near to C. smaragdula, but (even uniting all the 

 varieties usually placed together under this name) distinct by 

 its more robust form, strong punctuation of the elytra, which 

 are less narrowed at the apex, &c. The thorax has the 

 punctuation on each side of the median line very fine, at the 

 sides it is very coarse. The discoidal impressions are round 

 and coppery. Each elytron has three small impressions at 

 the base ; there is a coppery impression on the disk before 

 the middle, between the first and second costas, and inter- 

 rupting the second costa ; there are two small impressions 

 between the first and second costa just before they unite pos- 

 teriorly not diverting the costas, as is usually the case in C. 

 smaragdula. On the side there are three large impressions, 

 the first and second elongate, the third round and dividing 

 the third costa near its apex. The surface between this last 

 impression, and the apex of the elytra is more or less golden. 

 The apical segment of the abdomen has a small but wide 

 triangular emargination at the apex. 



This species differs from C. proximo., Saund., in having 

 the space on each side of the median line much less punctured ; 

 the impressions on the elytra are more coppery, and the 

 posterior lateral impression is not united to the posterior 

 impression, which is between the first and second costa.

Note. — The males of the species of this genus appear to 

 be rare. Of C. aurofoveata there are in the British Museum 

 three males and thirteen females ; of C. radians one male 

 and eleven females ; of C. occulta, ten females, no male, &c. 

 The males are easily distinguished by the broad triangular 

 emargination of the fifth abdominal segment, which leaves 

 the sixth pubescent segment exposed below. The thorax is 

 generally rather narrower, and the impressions are less marked.
