332 REVISION OP THE CICINDELIDjE OF AUSTRALIA, 



body is always quite glabrous; the head has one fully developed 

 supraorbital setigerous puncture placed in a position almost 

 intermediate between the positions of the two supraorbital setse 

 found in Cicindela, and a very small fine setule at the usual 

 position of the anterior seta; the labrum is large, convex, and 

 covers the mandibles in repose, it is 7-dentate with six fine 

 marginal setae placed in the notches dividing the teeth. The 

 clypeus is bisetigerous. The palpi in the male are pale 

 testaceous, with sometimes the apical joint merely a little 

 infuscate towards apex, sometimes piceous-black; in the female 

 the apical joint of the labial, and the two apical joints of the 

 maxillary are piceous; a similar sexual character is found in 

 Cicindela iosceles Hope, indicating an ancient origin and great 

 persistence for this apparently unimportant feature. The male 

 has the outer side of the intermediate tibiee not densely setose 

 towards the apex as in Megacephala and the Cicindelce verce. 



I have been unable to tabulate the species except by using the 

 pattern of the elytra, which it seems certain is insufficient for 

 differentiating species. I have therefore given notes on some of 

 the species after the table. 



Table of Species. 

 A. Elytra with apical maculae. 



Basal maculae only present at humeral angles; I D. undulata Westw. 



apical maculae triangular and not reaching suture \ D. volitans Macl. 

 Basal maculae extending inwards behind scutellum; apical maculae reach- 

 ing suture and forming a continuous transverse apical fascia when 

 elytra are closed. 



Basal and median maculae narrowly separated on sides. Prothorax 



not strongly rounded in middle of sides i D,Jiavicans Chaud. 



I D. mastersi Macl. 

 Basal and median maculae widely separated on sides. Prothorax 



smooth, strongly rounded on sides D.Jiavipes Macl. 



AA. Elytra without apical maculae. 



$• . Labrum black with pale median stripe. Mandibles with lower side 

 and apex black. Palpi with apical joints black. Length 13'5- 



16 mm D. gruti Pasc. 



J\ Labrum testaceous with narrow piceous margin. Mandibles testa- 

 ceous with apex piceous. Palpi pale testaceous. Length 10 mm 



D. parva Macl.
