TWO NEW AUSTRALIAN LUCANDI^. 

 By William Macleay, F.L.S., &c. 



In the preparation of the Paper which I read at last Meeting, 

 on the genus Lamprima, I was necessarily led to make a close 

 examination of all the Australian Pecticorns in my cabinets. Tl^e 

 result has been the discovery of two very remarkable insects, 

 hitherto I believe quite unknown. For one of these I am com- 

 pelled to form a new genus, it differs so widely from any previously 

 described; the other, though also of most distinctive and peculiar 

 appearance, may, I think, be very properly placed in the genus 

 Rhyssonotus 



HOMOLAMPRIMA. nov. gen. 



Mentum triangularly rounded in front, slightly transversal. 



Labium extending prominently beyond the mandibles. 



Maxillce. prominent, apparently corneous, hidden in long hair. 



Paljji strong, rather short. 



Mandibles short, exserted, not bearded on the inside. 



Head small, subquadrate.

Antennce short, stout, the first joint clavate and about the length 

 of the next six united, the three last forming a foliate club.

Elytra slightly convex. 



Prosternuin rather broad between the fore legs, terminating 

 behind in a prominent round point. 



Mesosternum terminating in front in a broad crescent shaped 

 emax'gination, as if to receive the prosternal process.
