2 02 TWO NEW AUSTRALIAN LUCANDIiE. 



One specimen, a male, is all I have ever seen of this strange 

 looking insect. It is labelled " New Holland," and has evidently 

 been in the old Macleay collection for a very long time. 



The shape of the head, and the sculpture of the elytra, give it 

 a very different aspect from either Rhyssonotus nebulosus or 

 jugularis, but it has notwithstanding a considerable affinity to the 

 latter of these. The only other known species, Rhyssonotus 

 parallelus, described by Deyrolle, in the " Ann. de la Soc. Ent. 

 de France," from a female caught in 1881, I have never seen, but 

 from the description and figure it seems in its parallel form to 

 resemble a little the present species. The resemblance, however, 

 does not extend beyond this, and it seems to me extremely 

 unlikely, therefore, that they are the sexes of the same species.
