566 DESCRIPTION OF A NEW TIGER-BEETLE, 



more prominent and preceded by a light lateral sinuosity, base 

 emarginate; elytra (6-5 x 4) with sutural mu crones stronger. 

 Length, g 10, $ 10-5; breadth, g 3-5, 9 4 mm. 

 Hab. —Western Australia, Condon (discovered by Mr. H. M. 

 Giles, of the Zoological Gardens, Perth, at Condon, where it was 

 plentiful. Four specimens (3 (J, 1 9) have been examined). 



This is the species which I had taken to be C. tetragramma 

 Boisd., when I described C. liiieifera (These Proceedings, 1913, 

 p. 401). Dr. Walther Horn, of Berlin, to whom I sent a cotype 

 of my C. lineifera, has assured me that C lineifera SI., is the 

 true C. tetragramma Boisd., and I recognise that his view is the 

 correct one. I have not now a specimen of G. tetragramma Boisd., 

 for comparison, but my note on C. lineifera shows that C. gilesi{^) 

 differs from C. tetragramma(^) by the metallic colour being 

 cupreous, not viridiseneous; prothorax not roundly ampliate on 

 sides, not narrowed at base, lateral basal nodes much more 

 strongly developed. 



C. trivittata Macl., and C. alholineata Macl., are distinct 

 species, differing from one another, and from C. tetragramma 

 Boisd., and C. gilesi SI. I have compared 0. gilesi{<^) with the 

 type-specimen(9) of C. trivittata, and the type-specimens (two 

 females) of C. alholineata in the Macleay Museum. From C. 

 trivittata (which I had wrongly concluded to be a variety of C. 

 tetragramma, cf. These Proceedings, 1906, p. 320), C. gilesi differs 

 by pattern of elytra (discal cupreous stripes not linked together 

 by two bars); prothorax with basal nodes less prominent, stouter 

 and far more obtuse at apex, not evidently in front of basal 

 margin and not with a marked sinuosity behind them. 



From C. alholineata, C. gilesi differs by pattern of elytra (not 

 with a broad metallic sutural area common to both elytra behind 

 scutellum); prothorax with lateral basal nodes far more promi- 

 nent, pronotum far less strongly and closely shagreened; labrum 

 not rounded or subprominent in middle of anterior margin, only 

 four submarginal setae in a transverse row (not one on each side 

 and from four t© six in middle). 



It will be useful to note here, that the valid species of the 

 tetragramma-gvon^ of the genus Cicindela are, at the present time,
