190 ON THE AUSTRALIAN CLiriNIDES, 



C. angustula seems to present considerable differences in colour 

 and size;* its constant features are the puncturation of the head 

 and prothorax, the form of the clypeus, the striation of the elytra, 

 the anterior femora not dilatate on lower side, the trochanters 

 prominent at Ijase of femora, and the digitation of the anterior 

 tibiae. 



I offer the following notes on some variations that have come 

 under my notice : — 



(1). A numerous series of specimens sent to me by Mr. A. M. 

 Lea, taken at Windsor, N.S.W., vary as follows: — 



Length 4-2-5-2, breadth 1-1-4: mm. Colour (a) testaceous 

 (immature); (b) ferruginous (slight!}^ immatui'e 1); (c) ferruginous 

 with interstices 2-5 of elytra obscurely piceous on posterior part 

 of disc; (d) ferruginous with interstices 2-5 wholly piceous except 

 at apex; (e) head and prothorax piceous brown, elytra reddish 

 with interstices 2-4 piceous black on posterior part of disc and 

 apical declivity. 



(2). Specimens from the Clarence River, also received from 

 Mr. Lea, are apparently narrower and more depressed, testaceous 

 with posterior part, excepting apices of interstices 2-4, obscurely 

 piceous. This form seems a variety or closely allied species, but 

 requires studying with more specimens than are available to me. 



(3). Specimens from Carrathool ( INIurrumbidgee River) have 

 the elytra more depressed; one specimen (immature) is pale 

 testaceous, the others are coloured as in the description above. 

 This form has also been sent to me by the Rev. T. Blackburn, from 

 South Australia; it seems likely to be C. deiylanata, Putz. 



(4). A specimen has been sent to me by the Rev. T. Blackburn, 

 which cannot in any way be distinguished from " No. 3 " above, 

 except by having the anterior femora with the lower edge form- 

 ing a decidedly acute triangular projection about anterior third. 

 This might be C. odonto'mera, Putz., but I should be unwilling to

 noted by M. Putzeys.
