458 ON CARABID.t: FROM WEST AUSTRALIA, 



Genus Gnathaphanus. 



33. Gn. rectangulus, Chaud. ; I.e. Sp. 665. Hub. — Upper 

 Ord and Behn Rivers (Helms). 



34. Gn. sulcatulus, Macl.; I.e. Supp. Sp. 7453. Hab. — Upper 

 Ord River (Helms). 



I have examined the types of Diaphoromerus sulcafuhis, Mael., 

 and D. sexfunctatus, Macl., in the Maeleay Museum and found 

 them identieal. I adopt stilcatiilus as the preferable name, and 

 place the species in the genus Guatliaphanus because it has the 

 third interstice of the elytra pluripunctate; it is allied to Gn. 

 adelaidce, Casteln. 



35. Gn. ADELAIDE, Casteln.; I.e. Sp. 656. Hah. — Swan River, 

 Pinjarrah, Mount Barker, Bunbur}' (Lea). 



Genus Diaphoromerus. 



I do not know characters by which this genus can be satis- 

 factorily defined and divided from Gnathaphanus; the differences 

 in the shape of the paraglossse are not likely to be of much value, 

 and that seems to have been the sole feature on which Baron 

 Chaudoir relied to separate these genera.* The two following 

 species are left in Diaphoromerus by me only because they have 

 been placed there by Chaudoir. 



36. D. in^.qualifbnnis, Casteln.; I.e. Sp. 684. IJab. — Swan 

 River, Darling Ranges, Mount Barker (Lea). 



37. D. sculptipennis, Casteln.; I.e. Sp. 698. IJah. — Rottnest 

 Island (Lea). 



Attention may be drawn to the fact that Chaudoir's measure- 

 ments of this species (Ann. Mus. Civ. Genov, 1878, xii. p. 488) 

 are too small; its length is 8-8'5 mm. 



Genus Hypharpax. 



Though T concur with the Rev. T. Blackburnf in placing in 

 Hyjjharphax the Australian Harpalids — not belonging to Phorti-
