REVISIONAL NOTES ON AUSTRALIAN CARABIDjE. 



By Thomas G. Sloane. 



Part II. 



Tribe vi.— Scaritini. 



The tribe Scaritini, as here limited, contains numerous and 

 highly specialised genera, and is found in all the large land areas 

 of the globe. I have not seen any record of its occurrence in 

 New Zealand, though it has been found in Lord Howe Island 

 (Scaraphites) and in New Caledonia (Scaritoderus). It is the most 

 important carabidous tribe in Australia, and as there represented 

 may be divided into two siibtribes, as under : — 



Buccal fissure not closed by sides of mentum, but extending backwards and 

 dividing submentum from paragenas."'' Elytra with lateral channel 

 granulate Scaritides. 



Buccal fissue closed posteriorly by the sides of the mentum. (Submentum 

 and paragenae contiguous.) Elytra with lateral channel Isevigate (never 

 granulatet among Australian forms) JPasimachides. 



Subtribe SCARITIDES. 

 Two Australian genera are known, each representing a 

 different and widely separated group in the subtribe Scaritides. 

 They are readily differentiated thus : — 



Maxilli© hooked at apex. Elytra strongly punctate-striate, interstices con- 

 vex. Eyes very small, not visible from above Stecjanomma. 



MaxilljB obtuse at apex. Elytra smooth (strias obsolescent). Eyes distinct. 

 Geoscaptns. 



*■ Parageme. In his Monograph of the Scaritides, Chaudoir proposed the 

 tevm. paragence ioY a 2Mrt of the underside of the head situated between the 

 channel in which the frst joint of tlie antenna' is lodged when the inject lays 

 them back, and the sides of the mentiiin. 



t In his ' Monograph,' Chaudoir records African species of this group with 

 the elytra non -granulate on the sides. 



X It appears that for the sake of uniformity in nomenclature, the Aus- 

 tralian group heretofore known as Carenides must be included in the Pasi- 

 MACHiDEs, the latter being the older name.
