branches and without the minute tooth at the base found 

 in Sihizoiiyclia. 



The male has the alKlonien more tumid beneath, and the 

 hind t'emoia of the temale are sliorter and thicker tlian those 

 of the male. 



Bj M. de Charmoy's desire the beetle has been named in 

 lionour oi Mr. G. Smith, hite actino- Governor of Mauritius, 

 in recognition of his interest in and support of the work of 

 investigation. 



This insect was very naturally ascribed to Schizonycha, a 

 great African genus to which it has a very great affinity, but 

 it seems to me extremely doubtful if that genus is really 

 represented in the Mascarene region. Schizonycka hova, 

 Coq., appears to belong to IJovachehis, and the quite insufii- 

 cieutly described S. glahra, Brenske, may belong to that 

 genus also. The genus Fhytalus represents in Tropical 

 America the African Schizonycha (a few species of which are 

 also found in Tropical Asia), and the two genera have the 

 closest affinity. Our insect differs from Schizonycha and 

 agrees with Phytalus in the following points : — The front 

 margin of the clypeus does not form a continuous curve, but 

 is notched in the middle, and the elytra have a well-defined 

 elevated strip bordering the suture and an ill-defined narrow 

 costa at a short distance from it. The antennae are very 

 short and consist of nine instead of ten joints. The same 

 number is found in certain species of Schizonycha (which 

 have been separated under the name of Atys), but this has 

 been produced by the fusion of the fourth and fifth joints 

 into a long rod. In Phytalus the seventh joint seems to 

 disappear and the structure of the antennee is very inconstant, 

 even the number of joints composing the club being variable.
