-erect and rather stout scales. On close examination many of 

 these appear to be truncated at the tip, with the tip itself 

 almost brush-like in character, or as if the scales had been 

 split downwards. I do not remember similar scales on any- 

 other weevil. The derm is everywhere entirely concealed, 

 and as. the type is unique and in perfect condition, it has not 

 been abraded. The palpi are quite distinct, but they may 

 have been accidentally forced out. The type was labelled 

 "Null" (41) and was from the collection of the late Rev. T. 

 Blackburn. 



Ethemaia alteknata, n. sp. 



Black, appendages obscurely diluted with red. Densely 

 clothed with sooty-brown scales, variegated with grey ; under- 

 surface mostty with greyish scales. In addition with sub- 

 erect stout setae or thin scales, more conspicuous on elevated 

 parts of elytra than elsewhere. 



Head rather feebly depressed between eyes. These round 

 and rather prominent. Rostrum about one-third longer than 

 wide, sides but feebly dilated to base, with feeble longitudinal 

 ridges. Antennae rather short and thin. Prothorax about as 

 long as wide, sides feebly rounded ; with rather large punc- 

 tures indicated through clothing. Elytra considerably wider 

 than prothorax, parallel-sided except at base and apex; with 

 regular rows of large, partially concealed punctures; suture, 

 third, fifth, and seventh interstices conspicuously elevated, 

 the third and fifth each with a tubercle crowning the posterior 

 declivity. Length, 5 mm. 



Hab. — South Australia: Lucindale (A. M. Lea). 



The complete absence of supra-ocular crests and infra- 

 ocular lobes exclude the species from Zejjhryne, but the third 

 tarsal- joint is very little wider than the second, and but 

 moderately bilobed, so that it is also aberrant for Ethemaia. 

 The sculpture of the prothorax and elytra are somewhat as 

 in Z. parallel a, but the head is very different. On the 

 rostrum the clothing greatly obscures the sculpture, but there 

 appear to be four ridges, of which the median ones are 

 stronger than the others ; but from some directions there 

 appear to be but two, and those but feebly elevated. The 

 strongly elevated alternate interstices, with the fifth having 

 a single tubercle, should prevent the species from being con- 

 fused with most species of the allied genera. On the type the 

 scales on the head are mostly greyish, on the prothorax the 

 surface is covered with alternating stripes of brown and grey, 

 on the elytra the scales on the sides and apical third are 

 mostly greyish.
