106 EEVISIONAL NOTES ON AUSTRALIAN CARABID.i^,!!., 



all the other genera of the Scaritides there treated of by the 

 following features in combination : — 



'' MaxilliE mala inferiore superiorem miiltum auperante. Maxillce mala 

 superiore apice obtuse rotundata. Episterna postica angustata longaque 

 (Elytra libera; species alatie). Elytra intra marginem hand carinata. Tarsi 

 articulo ultimo tenui elongato.^' 



In Chaudoir's index list of species at the end of his paper, all 

 Macleay and Castelnaii's species are reduced to two, viz., G. cacus, 

 Macl., and G. Uevissimus, Chaud. In this I concur, with a 

 reservation in favour of Scarites plicatuhis, Casteln. (Vide p. 107). 



Chaudoir distinguished the two well known species G. Icevissi- 

 mus and G. cacus from one another thus : — 



*' 1. Tibif.E intermedin' unispinosce, posticce extu!< simplices. . . .G. la^vissimus.^' 



*' 2. Tibioi intermedice bispinosa, posticce apice externo in dentem acutum pro- 



ducto G. cacus. " 



This accurately differentiates the typical forms of these two 

 species, but Queensland specimens have been given to me by Mr. 

 C. French as from "Winton District" and "Gulf of Carpentaria," 

 which have the facies of G. Icevissinius, but the second external 

 spine of the intermediate tibite almost as well defined as in G. 

 cacus, the posterior tibiae without an external apical tooth. This 

 form I consider identical with G. planiuscuLus, Macl. (from com- 

 parison with Macleay's type in the Australian Museum), but I 

 cannot see more in it than a form of G. lavissimiis.

I have examined the type of Sc. damastes, Macl., which was 

 placed under G. cacus by Chaudoir, and regard it as identical 

 with G. Icevissimus.
