250 REVISION OF THE AMYCTERIDES, iii., 



cate at base, tlie inner portion slightly raised, the outer extending 

 outwards, downwards, and backwards towards eye. Serobes 

 curved. Eyes large, ovate. Scape long. The rest as in Talaurinus. 



I have grave doubts as to the correctness of the position assigned 

 to Chriotyphus among the long-scaped genera. To my mind, the 

 cliaracters of the rostrum show much more affinity to several 

 Euomid genera; indeed its structure is practically identical with 

 that of Alexirhea, a genus which was also originally placed among 

 the long-scaped Amycterides. There is such considerable difference 

 of rostral structure in the Euomides, that I cannot regard them as 

 constituting a homogeneous group, but a good deal of further 

 study is required on this point. 



I have preferred, therefore, to describe here the species of 

 Chriotyphus known to me, leaving Alexirhea (w^hich, however, I 

 regard as its nearest ally) to be dealt with later. 



Chriotyphus acromialts Pasc, loc. cit., p. 19. 



Of the genus Chriotyphus, there are, before me, specimens which 

 I would refer to two different species. Unfortunately, I am not 

 absolutely certain which species is C. acromialis Pasc. One species 

 is represented by a female from Swan River, the other by a pair 

 from Onslow. The original specimens of C. acromialis came from 

 Champion Bay. 



Some little time ago, I sent my specimens to the British Museum 

 for comparison with the type. In reply, Mr. K. G. Blair kindly 

 wrote: "15, (Swan River specimen) agrees very well with type of 

 Ch. aeromialis Pasc, though the latter has not the purplish hue of 

 light colour, and the distribution of the dark colour does not quite 

 agree. In both these respects, our series shows considerable varia- 

 tion, one specimen (Swan River) being closer than others, though 

 another approaches very closely to type. Type has no tibial brush 

 and appears to be of the same sex as yours." 



"14-14a, have elytral tubercles distinctly smaller, and are more 

 scantily clad. They also appear longer and narrower; thoracic 

 tubercles seem to me similar, though, in w^ell clothed specimens, 

 they are almost hidden in light bands. One specimen of ours
