DESCRIPTION OF NEW COLEOPTEEA. 107 



the Rev. Hamlet Clark, M.A., F.L.S., of London, who has 

 made the water insects of Australia his particular study, and the 

 new species of the latter I have reserved for the Rev. R. L. King, 

 B.A., from whose pen I hope soon to see a valuable monograph 

 on the Brachehjtra of this country. 



1. CiCINDELA NlGRmA. 



Nigra feneo-micans, capite longitudinaliter thoraceque trans- 

 versim striolatis, elytris puuctatis ad suturam acuminatis 

 maculis duahus lateralibus alteraque apicali albis, corpora 

 subtus pedib usque seneo-viridibus. 

 Long. 4| lin., lat. 1^ lin. 

 The upper surface of this insect is almost black, with a 

 greenish tinge about the head and thorax. The under surface 

 and legs are of a brilliant metallic green. The mandibles, palpi, 

 and tarsi are of a pitchy hue ; the head is marked with very fine 

 strise. The thorax has the medial line slightly but distinctly 

 impressed, and is very finely marked with transverse striolas. 

 The elytra are coarsely punctured all over, and are truncated 

 at the apex obliquely, each having an acute elevated tooth at the 

 suture. The elytra have also a smooth white spot at the middle 

 of their lateral marg-ius, another at their posterior angles, and a 

 third, the smallest, at the truncated part of the apex. 

 Found on the sea beach about high water mark. 



2. — Odacantha micans. 



Picea nitida, thorace punctate, elytris antice striato-punctatis 



postice laBvibus, pedibus testaceis femoribus albis. 

 Long. 3 lin., lat. £ lin. 

 The whole insect is of a shining pitchy hue, which is darker 

 on the elytra. The head is deeply impressed, and wrinkled on 

 each side from the eyes towards the clypeus. The thorax is 

 closely punctured, with the medial line deeply marked, and a 

 longitudinal ridge on the sides. The elytra, which are twice the 

 width of the thorax, are punctured in stria3 very distinctly near their 

 base ; but towards the apex these marks become obliterated. The 

 legs have the upper half of the thighs and tibiae of a pale yellow. 

 Found under dried cow duns:.
