Sp. 12, D. Spencii. 



D. seneo-cuprea vel cuprea, supra et subtus pilis albis decumben- 

 tibus sparsim tecta : capite et thorace rugose punctatis : thorace 

 canaliculato, marginibus lateribus dentatis : scutello apice de- 

 presso, subpunctato : elytris subseriatim punctis confluentibus 

 notatis : pedibus viridibus, tarsis cyaneis : tibiis anticis externe 

 bidentatis, dentibus rufescentlbus. 



Long. Corp. 24- lin. 



This species is about the same size as the last, but its proportions 

 are very different. The head is very large ; the thorax is almost as 

 wide as the elytra, and has the anterior angles produced into a tooth- 

 like process ; dorsal channel indistinct ; the upper surface is uni- 

 formly and thickly covered with coarse punctures, which gives a dull 

 appearance to that part ; the lateral fovese are distinct. The scu- 

 teUum is somewhat heart-shaped, and has the apical portion de- 

 pressed and minutely punctured. 



I have seen but two specimens of this small species : one was 

 purchased from the collection of the late A. H. Haworth, Esq., by the 

 Rev. F. W. Hope ; for a loan of the other I am indebted to W. 

 Spence, Esq., after whom I have named it*.

" Black, with a white band on each side of the thorax. Elytra 

 red -n-ith the base and suture yeUow." 



Never having seen a specimen of this species, the above account 

 (which is from the work quoted) is all I am able to give. From its 

 colouring I should imagine it could scarcely be one of this genus. 



Mr. MacLeay, who has lately returned to England, having in a 

 most liberal manner lent me all his specimens of Diphucephala, I 

 am enabled to add three species which are distinct from those already 

 described. I subjoin them as an appendix, not being able to insert 

 them in their proper places, owing to the former part being already 

 in the printer's hands. In this gentleman's collection I find the fol- 

 lowing species : — Diph. sericea, splendens, anrulenta, parvula, Spencii, 

 pulchella, pilistriata, and the new species I am about to describe. 



I may here mention that I have also lately examined numerous 

 specimens of Diphucephala in the Collections of the Zoological So- 

 ciety and British Museum. The total number of specimens of this 



* Since writing the above I have examined many specimens, some of wliich are 

 in the collection of J. G. Children, Esq. The anterior angles of the thorax I find 

 are not produced in the females as in the males.
