336 REVISION OF THE CICINDELIDjE OP AUSTRALIA, 



I may here note that N. sloatiei seems an ancient form 

 descended from a stem in which the pubescence of the body had 

 never been acquired, and thereby differing from the tetragramma- 

 group of the genus Cicindela in which I believe the pubescence 

 to have been lost. 



Mr. Lea's description is wrong in saying " prothorax slightly 

 longer than broad." I have the type before me (kindly lent by 

 Mr. Lea), and find its thorax broader than long, the measure- 

 ments being as given above. Also, by a slip, the word " clypeus " 

 has been printed instead of labrum in the original description. 

 The labrum in the male is dark with a median testaceous stripe, 

 in the female of a uniform dark colour. It was found by Mr. 

 Lea running actively on the sandy bed of a dry creek at Mullewa, 



W.A. 



Genus Cicindela. 



Table of Species Groups. 



i. Labrum large, convex, 7-dentate, posterior tooth on each side lateral; 

 setae marginal.* Mentum with median tooth small or obsolescent. 



Labial palpi stout, apical joint small Cicindela spuria. 



A. Antennae with joints 5-11 swollen. (Elytra with subsutural row of 



foveas) iosceles-gvonp. 



AA. Antennae slender. 



B. Pronotum not strongly transversely impressed. Elytra opaque, 

 subsericeous, not strongly punctate; a subsutural row of lightly 



impressed foveae doddi-gxoxxp. 



BB. Prothorax encircled by a strong impression anteriorly and 

 posteriorly. Elytra convex, nitid, covered with a strong and 



dense puncturation tenuicollis- group . 



ii. Labrum short, never with lateral teeth, setae submarginal. Mentum with 

 median tooth long, pointed. Labial palpi slender, apical joint elongate 



, Cicindela yerje. 



C. Prothorax encircled by a deep anterior impression; pronotum convex, 

 glabrous. Elytra convex, covered with a strong puncturation, dark 

 green, not opaque (each elytron 3-maculate). J . With proepisterna 

 sparsely setose near coxae; mes- and metepisterna glabrous; apex of 



each elytron deeply excised and with a long apical sutural spine 



, nigrma-gxoup. 



* Sometimes the labrum has more than seven teeth, e.g., C. iosceles Hope, 

 ? , and G. doddi SI., ? , but the extra teeth in these cases are small and 

 seem merely a modification of the normal 7-dentate form.
