Mr. C. O. Waterhouse on new Goleoptera. 381 



Chrysodema ventralis, n. sp. 

 Lsete aureo-viridis, nitida ; thorace crebre punctato, lateribus im- 

 pressione sat magna aurea ornatis, angulis posticis acutis paulo 

 divergentibus : elytris multicostatis, costis laevibus, interstitiis 

 crebre punctatis ; apice ipso cupreo ; corpore subtus pedibusque 

 cupreis. 

 Long. 10 lin. 



A very distinct species by its elongate elliptical form. The 

 thorax is obliquely narrowed in front, broadest at the poste- 

 rior angles, which are more diverging than in any species 

 known to me. The surface is closely and not very finely 

 punctured, with a slight smooth line in the middle ; on each 

 side there is a rather large, shallow, golden, punctured im- 

 pression, which touches the margin. Each elytron has eight 

 nearly equal rather strong costs? ; the third costa is oblite- 

 rated at the base by some very coarse punctures ; the fifth 

 does not reach the shoulder or the apex ; the interstices are 

 narrow and somewhat irregular. The whole of the under 

 side of the body (except the sides of the sterna) is coppery.

Cyjyhogastra terminata, n. sp. 



Viridis, nitida ; thorace aureo-impresso ; elytris sat fortiter punctatis, 



ante apicem cupreis, apice ipso nigro-violaceo ; tarsis flavis. 

 Long. 15 lin. 



Allied to C. punctipennis, Deyr., but broader and more 

 robust. The thorax has the median line and two small round 

 impressions in front golden ; the rather large lateral impres- 

 sions are deep, golden, densely and finely punctured, and 

 filled with dark yellow tomentum. The elytra are nearly 

 parallel for more than half their length and then are gradually 

 narrowed to the apex, and not compressed, as is so fre- 

 quently the case in this genus ; the punctuation is strong, 

 rather more uniform than in C. punctipennis. The tarsi are 

 yellow, except the last joint, which is green. 



This species is also near C. satrapa, Sch. (suturalis, F.), 

 but the two impressions in the front of the thorax are more 

 distinct ; the lateral impressions are larger ; the punctuation 

 of the elytra is more uniformly strong, the copper colour is 

 less extended at the apex, and the apex is more acute.

Cyphogastra abdo?m'nalis ) n. sp.

obscure cupreo tincto ; abdomine cupreo-nitido.
