dentate, although the iinchannelled under surface of the abdomen 

 indicates the specimen to be a female. The body beneath is dark 

 green and punctured; tlie middle of the metasternum and base of 

 the abdomen tinned with golden colour. The sternum differs in 

 form from that of the two other species, being rounded and widest 

 in front (fig. 5 b, 5 c). 



The unique specimen from which the above description was 

 made is in the Collection of W. VV. Saunders, Esq., F.R.S,, cVc, 

 who pointed it out to me as distinct from the two present known 

 species, and with whose name I have therefore specifically de- 

 scribed it.

This new species is of the same size as On. irivittata, but is 

 rather wider across the hind part of the prothorax and base of the 

 elytra. The head is black, glossy and punctured ; the punctures 

 forming short striolae on the anterior half of the head, which is 

 attenuated, the lateral anterior angles forming two porrected 

 points, which are subprismatical and rather hollowed out on the 

 outside; the middle of the narrowed anterior margin is also pro- 

 duced into a short conical point. The disk of the liead is marked 

 between the eyes with two small white round spots ; there are 

 also two still smaller, close to the eyes, behind, and two oblong 

 patclies running parallel with the sides of the head. The antennee 

 are black, with the clava pitchy. The maxillse are elongated, and 

 both the upper and lower lobes are armed with a number of very 

 strong curved spines (fig. Ga). The mentum is oblong, hairy out- 

 side, and with a very deep triangular incision in front (fig. 6 b). The 

 pronotum is short and broad, the lateral margins regularly rounded 

 and not elevated at the hinder angles ; the disc is entire and 

 finely but numerously punctured. The scutellum is elongate, tri- 

 angular, nearly smooth. The elytra are but slightly punctured on 

 the disk, but more strongly so at the sides and towards the apex, 

 where the punctures become elongated curved striolee. The 

 suture is elevated as well as two longitudinal carina? on each 

 elytron, the interior being the most decided. The pronotum, scu-
