of New Insects from New Holland, cxxix 



of these constituting the base of the triangle are parallel with the anterior margin of 

 the prothorax, and are prominent and polished ; the third, constituting its apex, is 

 nearer the scutellum and is almost obsolete. The legs are rather short and small, 

 and the thighs are slightly incrassated. 



Hab.— New Zealand: in the possession of Mr. S. Stevens; consigned to that 

 gentleman by Mr. Mossman. It is related to Aromia and Rosalia, but totally desti- 

 tute of the beauty which the species of those genera possess. 



Genus — Omotes, Newman. 



Omotes punctissima. 



Testacea, oculis tantum nigris, puncta, pilis testaceis obsita, parum depressa ; elytra 

 profunde ac confertlm puncta. (Corp. long. '25 unc. Elytrorum lat. max. *045 

 unc.) 



Entirely testaceous, the eyes alone being black, beset with testaceous hairs, all 

 parts punctured, but the elytra deeply and confluently so. Seeing how extraordinary 

 is the variation in size between individual Australian longicorus of the same species, 

 I was at first sight strongly inclined to consider this diminutive insect as nothing 

 more than a small, dark-coloured specimen of Omotes Cucujides, a single example of 

 which was captured by Mr. Higgins, and described by myself, some ten years back, 

 in the ' Entomologist:' however, on carefully comparing the two specimens, I was in- 

 duced to abandon this view, since other characters far more important than those of 

 magnitude or colour were revealed, and seem clearly to indicate that the insect now 

 under consideration is specifically distinct: in O. Cucujides the prothorax is slightly 

 depressed dorsally, and slightly, almost imperceptibly, rounded laterally ; in punc- 

 tissima it is perfectly cylindrical dorsally, without depression, laterally quite straight, 

 and also longer in proportion to its width : in 0. Cucujides the elytra are decidedly 

 flattened dorsally, highly polished and glittering ; in punctissima they are scarcely 

 depressed, and so completely covered with deep and confluent punctures, that there 

 is no glittering appearance whatever : the legs, short in both species, are proportion- 

 ately shorter in punctissima. 



Hab. — South Australia : in the cabinet of Mr. Westwood ; to whose kindness I 

 am indebted for the loan of this interesting little species. 



Family — L amiid^e . 



Genus — Rhytiphoka, Serville. 



Rhytiphora Donovani. 



Fusca; antenna piceo-fuscce, nigro fimbriates, articulis basi cinereo-lanuginosis : caput 

 et prothorax fusca, hie fasciis illud maculis fulvo-lanuginosis ornata ; scutellum 

 fuscum ; elytra fusca, tuberibus prominulis basi, maculis fulvo-lanuginosis undique, 

 vittd lata costali ante humerum interrupta nivect, ornata. (Corp. long. "65 unc. 

 Elytrorum lat. max. "225 unc.) 



This insect in size and general appearance resembles Saperda nigro-virens of Do- 

 novan, but the absence of all green colour in the elytra, and the interruption of the
