SUPPLEMENT TO THE " REVISION OF THE 

 CICINDELID^E OF AUSTRALIA." 



By Thomas G. Sloane. 



After I had finished my ' Revision of the Cicindelidse of Aus- 

 tralia ' I had the opportunity of meeting Mr. Henry Hacker, a 

 visitor to Sydney, who brought with him a number of Cicindelids 

 which he had captured last summer in the vicinity of Coen, 150 

 miles north of Cooktown, Queensland. My thanks are specially 

 due to Mr. Hacker for the opportunity of examining his Coen 

 collection, and for the gift of specimens of the new forms therein 

 contained. I identify the species found by Mr. Hacker at Coen 

 as under : — 



Distypsidera gruti Pascoe. C. leai Sloane, and var. nigella, 



D. parva Macleay. n.var. 



D. hacker i, n.sp. C. semicincta Br u lie. 



Cicindela iosceles Hope. Tricoitdyla aptera Oliv. 



C. doddi Sloane, and var. semiviridis, n.var. 



Mr. Hacker informed me that all the species of Cicindela 

 mentioned above were taken on the ground, along tracks and 

 similar places in open forest country. 



Mr. C. French has also sent to me, for description, a specimen of 

 a new and remarkable species of Megacephala. 



Megacephala marginicollis, n.sp.

 notum on disc atrous, inflexed margins of elytra piceous; under

 first ventral segment; head viridescent beneath eyes and behind 

 base of maxillee; ventral segments 3-5 with narrow brown posterior
