330 REVISION OP THE CICINDELIDiE OF AUSTRALIA, 



Table of Australian Genera of the Tribe Cicindelini. 



Labial palpi with basal stalk long; (penultimate joint long, slender. Pro- 

 episterna rugulose. Elytra simply punctate. Head with one supraorbital 



seta. Under surface glabrous) Ehysopleura. 



Labial palpi with basal piece short. 

 Elytra with intricate punctate-undulate sculpture. (Head with one 

 fully developed supraorbital seta.f Under surface and all coxae 

 glabrous. Metepisterna with a deep horse- shoe-shaped impression 



posteriorly) Distypsidera. 



Elytra not with punctate-undulate sculpture. 



Body, including all sternal side-pieces and coxae, glabrous. Head 

 with one fully developed supraorbital puncture. Clypeus with a 



juxta-antennal seta on each side Nickerlea* 



Body normally with at least some bristles or pubescence on one or 

 more of the sternal sidepieces and coxa? (in tetragramma -group body 

 and posterior coxas glabrous). Head with two fully developed 



supraorbital punctures. Clypeus without juxta-antennal seta? 



Cicindela. 



Rhysopleura, n.g. 



Head with one supraorbital setigerous puncture; clypeus 

 bisetigerous. Mentum with a distinct pointed median tooth ; 

 lobes pointed at apex. Maxillce with outer lobe two-jointed; 



* The characters attributed to Nickerlea here are those of Cicindela sloanei 

 Lea; N. distypsideroides Horn, the type of the genus, is unknown to me in 

 nature, but I believe it will show the setae of the head and clypeus as in 

 C. sloanei, which I place in Nickerlea with considerable hesitation. 



t- While this paper has been passing through the press, I have been 

 informed by Dr. Horn that, in the genus Distypsidera, there is a small fine 

 anterior intraorbital seta placed as in the genus Cicindela. Dr. Horn 

 reports this seta in D. undulata. D. gruti, and D. flavipes; and I have since 

 found it in D. parva. I had failed to detect this little seta, the pore from 

 which it rises being so minute that, if the seta is rubbed off (as it usually is, 

 judging from <my specimens of Distypsidera) its presence would not be 

 suspected. I have not thought the discovery of this greatly reduced anterior 

 seta invalidates entirely the distinction I have sought to establish between 

 the genera Distypsidera and Cicindela by the use of the supraorbital setae; 

 but for the sake of accuracy, and to prevent misunderstanding, I now refer 

 to the fully developed supraorbital setae. In Distypsidera the posterior seta 

 is placed much more forward than in Cicindela.
