of some New Species of Exotic Lucanida:. 213 



minuto medio, postica; in medio inermes. Corpus et pedes 



subtus picea, punctata. 

 Focmina minor ; capite et pronotomagnitudinis ordinariae, vertice 



depresso, et utrinque tuberculo rangis distincto instructo. 



Mandibular parvte, apice acuta^, denteque unico intus armatse. 



Prothorax lateribus rotundatis, angulis anticis acutis. 

 Both sexes of this curious species from New Zealand are con- 

 tained in my own collection. The male is especially remarkable 

 for the broad prothorax, which is porrected in front, and the wide 

 head with a deep circular excavation in the middle. The genera 

 Scortizus and Sclerostomus, to which this species is most nearly 

 allied, are known only as natives of South America. The general 

 character of the species before us, however, as well as the cha- 

 racter of its vnaxillse, varying, as it does, in the opposite sexes, 

 seems fully to warrant its reference to the latter of these two 

 genera, thus establishing another instance of the geographical re- 

 lationship between the objects of South America and Australasia 

 which has been alluded to above.

The New Zealand genus DENDROBLAX, described by Mr. 

 A. White in the " Zoological Volume of the Voyage of the Erebus 

 and Terror," is composed of a single species (JD. Eariianus,\Nh,) 

 and may be regarded as an obscure representative of Splienogna- 

 thits with the mouth of Sinodendron. The species (of which I 

 possess both sexes) is remarkable for having winged males and 

 apterous females.
