378 ON THE (JARENIDES (FAM. CARABID.E), No. IV., 



impression; ashort wide shallow impression near each basal sinuosity. 

 Elytra oval (12-2 x 8*8 mm), lightly emarginate, obliquely 

 declivous between humeral angles, convex, evenly rounded on 

 sides: border thick, prominent and upturned at humeral angles; 

 punctures of base (5 or 6) in two transverse rows (the punctures 

 of posterior row smaller than those of anterior row). Presternum 

 with intercoxal part widely channelled, truncate at apex, with a 

 single puncture at each side. Anterior tibiae tridentate, two 

 small prominences above larger teeth. Length 25, breadth 8 -8 mm. 



Hob. — North- West Australia (Colls. French and Sloane). 

 Sent to me by Mr. French, who reports it as having been found 

 by one of his friends on a journey from Port Darwin to the 

 Lennard River. 



Its position is between C. habilans, 81., and C. tUyans, Macl., 

 to both of which it has affinities, and which it proves to belong 

 to one group of species. Differences between it and G. kabitmis 

 to which attention may be directed are, the anterior tibiye more 

 swollen in middle of lower side, posterior tibiae much more slender 

 and less incrassate to apex; the prothorax with three marginal 

 punctures on each side. The larger and heavier head with one 

 supraorbital puncture on each side differentiates it from C. elegans 

 and allied species. The divergent frontal sulci readily separate 

 it from C. virescens, SI., and other species with short parallel 

 frontal sulci. 



Carenum dispar, Macl. 



Mr. French has a specimen of ('. (lis par (which I have com- 

 pared with the type in the Macleay Collection) from the Mallee 

 Districts of North-west Victoria. 



Carenum subcvaneum, Macl. 



I have examined the types of C. sabcyaneum, Macl., in the 

 Macleay Museum, and have noted the presence of an oblique 

 supraorbital sulcus on each side of the occiput. The species 

 noted by me as C. sulcaticpps, var. C. (P.L.S.N.S. W. 1897, xxii.
