598 REVISIONAL NOTES ON AUSTRALIAN CARABID-S, V., 



sensitive hair on each side; front lightly and widely bi-im- 

 pressed. Mentum with median tooth short j wide, not excised 

 at apex. Prothorax subconvex, transverse (415 x6 mm.); 

 apex with median part truncate ; anterior angles widely 

 rounded, a little more prominent than median part; sides 

 ampliate, roundly subangulate at widest part, strongly angus- 

 tate and sinuate to base : basal angles subrectangular with 

 summit rounded ; upper surface punctate, more closely so 

 towards sides ; punctures separate, and derm not rugulose to- 

 wards centre. Elytra much wider than prothorax (13-2 x 84 

 mm.); striae shallow, finely and closely punctate; interstices 

 finely shagreened, biseriately punctate; the punctures sepa- 

 rate, not coarse, not interrupting the summits of interstices. 

 Length 20-23-5, breadth 6-8-84 mm. 



Hah. — Prince of Wales Island, Torres Straits. I am in- 

 debted to Mr. H.J. Carter for a specimen, and two others are 

 in his collection. 



Allied to G. sulcatum MacL, and G. froggatti Macl. ; but 

 differing from G. sulcafu?n by punctures of head fewer, small- 

 er and not so close together ; prothorax roundly subangulate 

 at widest part, more strongly angustate to base, punctures not 

 so coarse or so close together ; elytra with interstices more 

 opaque and depressed, not raised into prominent ridges, the 

 punctures of each row on interstices 2-7 finer, more distant 

 from one another, not causing any crenulation or interruption 

 of the summits of the interstices as in G. sulcatum. From G. 

 froggatti, by head and prothorax less closely punctate; pro- 

 thorax much wider ; elytra with interstices less costate, even 

 interstices not confusedly punctate, etc. It might be thought 

 to be a well marked variety of G. sulcatum, but I have pre- 

 ferred to regard it as a distinct species.

 Paraglossse cartilaginous, free at apex. Maxillae with inner 

 lobe densely setose on upper side and apex, triangularly pro- 

 minent at middle of inner side. Palpi long; penultimate joint 

 of maxillary not shorter than apical joint. Prothorax with
