102 NEW SPECIES OF AUSTRALIAN COLEOPTERA, 



variety of C. S2:)ectahilis, variable as is that species. Seen from 

 above, the head of C. foveatus appears to be in two distinct 

 lobes, whilst that of C. spectabilis is regularly convex; the apex 

 of the rostrum is always narrower; the punctures and fovere are 

 very much larger, those on the prothorax and elytra being fully 

 twice as large as in C. spectabilis: on the elytra of the latter 

 species the fovese are usually subquadrate, whilst in C. foveatus 

 they seldom are; the elytra are much less parallel-sided (they might 

 fairly be called wedge-shaped) than in C. sjyectahilisj and the 

 posterior declivity is much more abrupt (fully 15° nearer to the 

 perpendicular); the scutellum is only about half the size of that 

 of C. spectabilis^ the prothorax is much more con\'ex, and the 

 punctures of the under surface are very different. The body in 

 G. foveatus at the hind cox£e is deeper than wide, whilst in C. 

 spectabilis it is there distinctly wider than deep. The clothing 

 (apart from colour) is essentially different as on the under surface, 

 legs and head it is never squamose, whilst such scales as are 

 present on the elytra are always elongate (in C. spectabilis the 

 paler scales are more or less oval) and are never (in the three 

 specimens before me) in spots; on all three, however, they form 

 a feeble and obscure fascia at the apical third. There are also 

 no black scales such as are usually present (and rather dense) in 

 the elytral punctures or fovese of C. sjyectabilis. 



ChRYSOLOPHUS SPECTABILIS, Dej. 



This species occurs in Queensland, New South Wales, Victoria, 

 and South Australia. The clothing (which is of a peculiarly 

 soft lustrous nature and has caused the species to be named the 

 *' Australian diamond-beetle ") varies from a pale yellowish-green 

 to deep blue, but in the majority of specimens is of a decided green. 

 In addition to the green scales, however, there are some deep 

 black ones, but these are smaller and not visible to the naked eye. 

 The size varies from 10 to 28 mm. 



The green scales are sometimes almost confined to the punctures, 

 at other times they almost entirely conceal the derm. Mr. 

 J. G. O. Tepper has given me some specimens from Kangaroo
