560 SUPPLEMENT TO THE " REVISION OF THE CICINDELID.E." 



I look upon it as a well-marked variety of C. leai SI., though 

 most collectors will probably regard it as a distinct species. 

 From the typical form of C. leai it is differentiated by its black 

 colour, prothorax less rotundate between the pronotal sulci, which 

 are shallower (although the measurements of the prothorax are 

 the same in both forms, the prothorax of the typical form is more 

 bulged on the sides and more convex on the disc, which causes 

 the transverse sulci to be more deeply marked). The labrum 

 appears more rounded on the sides and to have the dentate part 

 of the margin shorter and more rounded. Several specimens 

 were given to me by Mr. Hacker. 



Tricondyla aptera Olivier. 



The discovery of T. aptera on the mainland of Australia gives 

 us a solitary representative of Dr. W. Horn's division Cictnde- 

 LiD^E-ALACOSTERNALiE, although this species cannot be looked 

 upon as more than an immigrant from Papua. It is an important 

 addition to the many Papuan Coleoptera which have invaded the 

 Cape York Peninsula. Mr. Hacker's specimens (two) were taken 

 running very actively on the trunk of a fallen tree. 



Corrigenda. 



In the "Revision of the Cicindelidse of Australia," (antea p. 309) 

 fig. 113, PL xxx., shows the posterior trochanter of Cicindela 

 semicincta Brulle, bearing a tactile seta. This is an error. I 

 have never seen a Cicindelid with any seta on the posterior 

 trochanters {of. p. 3 13, last line).
