(j). Mr. F. P. Dodd recently sent me the female from Kuranda; 

 it differs from the male by size larger (length 9 mm.), pro- and 

 mesepisterna glabrous; labrum larger and longer, teeth far more 

 prominent (median tooth prominent, triangular, flanked on each 

 side by a subdentiform prominence; on each side of this wide 

 tridentate median prominence a deep setigerous notch, and behind 

 this setigerous notch two strong triangular teeth, side of labrum 

 roundly dilatate some distance behind the outer of these teeth, 

 a marginal seta just before this lateral dilatation). The descrip- 

 tion above applies to the labrum from the apex; taking it from 

 the base it is wide, strongly sinuately narrowed at about half the 

 length, 7-dentate before this lateral sinuosity of each side. I 

 regard this as only a modification of the 7-dentate form of the 

 labrum, in which the posterior lateral tooth has become reduced 

 to a mere rounded prominence, and the second tooth from the 

 base has become duplicated. 



Tenuicollis-Group. 



C. oblongicollis Macl., is closely allied to G. tenuicollis Macl. 

 When examining the types of these species in the Macleay 

 Museum, I could not fix on any point of difference between 'them, 

 except the dark obscure colour of C. oblongicollis. 



G. tenuicollis Macl., is chai'acterised by its prothorax with a 

 very deep encircling groove anteriorly and posteriorly, the inter- 

 vening space being roundly convex. 



C. leai SI., is the same colour as G. tenuicollis Macl., but with 

 prothorax wider (1*3 x 1 - 3; G. tenuicollis 1 25 x 1*1 mm.); pro- 

 notum with apical and basal sulci much shallower, sides and disc 

 far less strongly rounded between these sulci. In fresh specimens 

 a few scattered seta? may be noticed rising from the punctures 

 towards the base of the elytra; doubtless similar setae are present 

 in fresh specimens of the other' two species of this group.

. Nigrina-Group. 

 This group has only one species (G. nigrina Macl.), an ancient 

 and isolated form remarkable for the shape of the apex of the
