MPHAMORPHOS, ROB WEE. 



SYNOPSIS OF THE SPECIES. 



Of this genus two species only are known; they were 

 both introduced and described in detail by Mr. Rohwer. 

 in Entomological News, vol. xxi, p. 474 (December 1910). 

 The £? differ conspicuously both in size and colour- 

 as follows — 



??• 

 — Larger, length about (> mm. Head, thorax, and abdomen 

 black without red markings .... nigrescens, Rohw. 



Victoria. Type in B.M. 



— Smaller, length about 4 mm. Head and thorax black, but 

 abdomen with a broad red belt covering at least four conse- 

 cutive segments. (These $9 superficially resemble small ,] ] 

 of Clarissa divergens, but are naturally broader in proportion 

 to their length, and the antennae (PI. XII, Fig. 11) have 

 more joints, and taper mote towards their apices.) 



minor. Rohwer. 

 North Queensland. Type in B.M. 



&?. 

 The <$ of nigrescens is unknown. That of minor differs 

 from the $ in having the abdomen entirely black, and also, 

 in such specimens as I have examined, in having 16- 

 jointed antennae, these in the $ seem to be always 

 15-jointed. 



EURYS, NEWMAN. 



SYNOPSIS OF THE SPECIES. 



Eurys and the genera most allied to it have been sup- 

 posed to be distinguishable among themselves by differences 

 in the number of joints in their antennae. But even in 

 the very limited material before me I find these differences 

 far from constant. Generally no doubt the number of 

 these joints in Eurys -or at any rate in its $$ — is 9. 

 But in one of the three $ specimens of E. laetus in B.M. 

 the Dumber is 10. It is 10 also in a specimen which Mr. 

 Rohwer has ticketed as the " Type ^ " of his n. sp. deceptus, 

 and in one of two others marked by him as " paratypes "
