wpon some new and rare Coleoptera. 83 



South American division of the same group, formed into a sepa- 

 rate family by Eschscholz, under the name of Conognatha. 



The only two species of New Holland Stigmodera I am ac- 

 quainted with, bearing any resemblance to it as to form and cha- 

 racter, are Stigmodera Jaqu'moti of Gory, and Calodema Kirhii of 

 Hope. It partakes of the somewhat attenuated and rather convex 

 form, with strongly spinose apex of the former, but differs in 

 having the thorax more convex, with the sternum prolonged in a 

 most remarkable manner (vide fig. 7 a); the apex of each elytron 

 is also of a different form, having three spines (vide fig. 1 h) in- 

 stead of two (vide fig. 7c). 



It agrees with Calodema only in having the prosternura pro- 

 longed (but in a more conical form, vide fig. Id), and spinose apex 

 of elytra, but having, as I have before mentioned, three spines 

 instead of two (vide fig. 7e). And here let me mention that the 

 only New Holland species of Stigmodera with which I am ac- 

 quainted possessing the lengthened prosternum are the present 

 new species and Calodema Kirbii, whereas the South American 

 division Conognatha possesses it with one or two exceptions in a 

 remarkable manner ; with regard however to the six distinct 

 spines at the apex it stands alone, and as such forms a peculiar 

 feature in this new sub-division. 



Upon the whole it certainly bears a greater affinity to the South 

 American division ; but differing as it does in several respects, and 

 coming from another country, I have thought it expedient to make 

 it the type of a new sub-division, under the name of Metaxymorpha, 

 derived from the Greek fxETulv, between (to express intermediate 

 or connection), and [xopcpt], a form : and have much pleasure in 

 naming this new insect after my friend J. E. Gray, Esq., F.R.S., 

 of the British Museum, for whose kindness and attention on my 

 frequent visits there I feel greatly indebted.

The male of this new species of Trictenotoma was lately de- 

 scribed by Mr. Westwood in his publication on Oriental Ento- 

 mology, (vide pi. 23 of that work,) it having been sent to him 

 from the island of Ceylon by R. Templeton, Esq., in whose
