colour, less strongly shagreened and more distinctly punctured; 

 labrum with a large apical infuscate patch, median tooth in the 

 female much stronger, &c. 



C. mastersi and G. catoptriola have ihe prothorax decidedly 

 rounded on the sides; the pi^osternal episterna seneous and finely 

 rugulose; labrum with edge only infuscate. C. catoptriola Horn 

 (= C. curvicollis SI.), may be readily separated from C. mastersi 

 by the uniform bronzy colour of the upper surface, the lateral 

 transverse mark of the elytra very small or obsolete, the posterior 

 discal spot very small and inconspicuous, the apical and humeral 

 marginal spots wanting. Dr. W. Horn, to whom I sent speci- 

 mens of my G. curvicollis, has informed me that it is synonymous 

 with his G. catoptriola, which he now looks upon as merely a race 

 of C. mastersi; to me it looks sufficiently distinct to require a 

 separate name. 



Habits. — Rhysopleura orbicollis SI., is found on the mossy 

 trunks of scrub-trees at Kuranda, Queensland. All the species 

 of Distypsidera are found on the trunks of trees. The Cicindelce 

 spuria} are terrestrial in their habits; Mr. Lea found C. sloanei 

 Lea, in the sandy bed of a dry creek at Mullewa, inland from 

 Champion Bay. Mr. Hacker found C. iosceles Hope, and G. leai 

 SI., beside the railway line near Cooktown; and Mr. Froggatt 

 obtained C. tenuicollis Macl., and C. oblongicollis Macl., 100 miles 

 inland from King's Sound. G. nigrina Macl., and the species of 

 the tetrayramma- and ypsilon-gvon^H frequent sea beaches, as also 

 does, I believe, G. scetigera Horn. I have taken C. mastersi in 

 different places in New South Wales in open forest country — on 

 the margin of swamps near Urana, and on the margin of Lake 

 Cudgellico, near the Lachlan River; doubtless all the species of 

 the semicincta-growp have similar habits. 



Geographical Distribution. 



The publication of Dr. Walther Horn's " Systematischer Index 

 der Cicindeliden " furnishes data for reviewing the geographical 

 distribution of the Cicindelidee, and lias enabled me to offer the
