604 REVISION AL NOTES ON AUSTRALIAN CARABID^, V., 



Prothorax broader than long (5x7 mm.) ; anterior margin 

 with a sinuosity on each side near neck, median part subemar- 

 ginate, slightly more advanced than anterior angles, sides 

 strongly rounded anteriorly, obliquely narrowed posteriorly ; 

 disc nitid, strongly raised above margins, sparsely punctate 

 (the punctures very scattered in middle). Elytra ordinary 

 (17x10 mm.); interstices closely punctate, more or less bi- 

 seriately punctate towards base ; punctures becoming 3-seriate 

 towards apex on odd interstices, 4-seriate on even interstices. 



9- Differs from cT, by head with postocular prominences 

 less developed; prothorax narrower (4-6 x 6-3 mm.). 



Length 29, breadth 10 mm. 



//«6.— Queensland : Cunnamulla (Hardcastle). Two speci- 

 mens (cf $) received from Mr. A. M. Lea(Colls. Lea and 

 Sloane). 



Allied to G. noctt Newm., but differing from all the forms 

 of that species, which I have seen, by postocular prominences 

 more strongly developed (especially in cT) ; prothorax with 

 median part of the anterior margin more prominent in com- 

 parison with the anterior angles : elytra with interstices more 

 finely and closely punctate. It cannot be G. longius Blkb., or 

 G longicolh Blkb., (both unknown to me in nature) on 

 account of the different puncturation of the elytra, and the 

 postocular prominences in both sexes more prominent than in 

 G . hostocki Cast., (the prominence in 9 being more below the 

 eye than in G. hostocki). Blackburn indicated his G. eremita 

 (which I cannot differentiate from G. bosforki) as being a 

 species with well developed postocular prominences.* These 

 prominences also differentiate it from G. dux Blkb., which is 

 said to be without them.* I look upon it as the most primi- 

 tive species of the //or/'e-group, but cannot see any reason for 

 supposing that it is descended from the (jra?ide-stem. ; it seems 

 rather an offshoot from some ancient generalised form.
