transverse row of six submarginal punctures; anterior margin 

 arcuate on each side, a small obtuse triangular prominence in 

 middle. Prothorax roughly shagreened, depressed, broader than 

 long (2-25 X 2*85 mm.), narrower at apex (2-15 mm.) than at base 

 (2-75 mm. at posterior angles), constricted by an arched impres- 

 sion near anterior margin; a light wide transverse impression 

 near base; posterior angles obtuse, but distant from basal margin. 

 Elytra oval (9x5 mm.), convex, punctate (the green part coarsely, 

 the whitish parts finely punctate); humeral impression well 

 marked, wide; apical curve roundly, widel}^, and lightly em arginate 

 in middle; suture ending in a short mucro. Length 12-7, 

 breadth 5 mm.

 Sent to me by Mr, A. M. Lea. 



The largest Australian species of the genus Cicindela; it is 

 allied to G. albolineata Macl., and G. trivittata Macl.; from both 

 of which (also from G. tetragramma Boisd.) it differs by the 

 pattern of the elytra; less prominent posterior angles of prothorax, 



&c. 



Cicindela mastersi, Casteluau. 



Mr. i". P. Dodd sent me specimens of a Cicindela taken by him 

 inland from Cairns (open forest country about Mareeba, Mount 

 Garnet, &c.) which has the elytral pattern of G. mastersi (though 

 a little more reduced, and without any humeral white spot in 

 either sex), It is conspecific with G. pleheia SI., and indicates 

 that G. pleheia was described from a dark form, probably peculiar 

 to the heavily timbered coastal districts of North Queensland. 



A comparison of Mr. Dodd's inland specimens mentioned above, 

 with C. curvicollis SI., (a synonym of G. catoptriola Horn), from 

 North-West Australia compels me to consider them conspecific, 

 so that I have now no objection to urge against Dr. Horn's view, 

 that this smaller tropical form is a variety of C. mastersi.* I 

 would, therefore, catalogue it as C mastersi Castelnau, var. 

 catoptriola Horn, = (7. pleheia Sloane.
