130 Mr. Arthur M. Lea's Revidon of the 



seen to be long, thin, strongly curved, sharp-pointed and 

 edged and perfectly simple. 



The prothorax is but little, or not at all, narrower than 

 the elytra ; and is usually impunctate, or if any punctures 

 are present these are confined to the margins; the head 

 also is either indistinctly or not at all j^unctate (except in 

 Jiavipennis) ; the elytra, however, are usually densely and 

 rugosely punctate. 



In the male the penultimate segment of the abdomen is 

 deeply excised, often semicircularly, but sometimes to the 

 base itself ; the preceding segment is widely emarginate 

 or simple. In the female the abdomen is usually quite 

 simple, but sometimes the penultimate segment appears 

 lobed in the middle, with a depression on each side of the 

 lobe : but the apex itself is not emarginate, or if so then 

 throughout its entire length. 



The tibiae seem to be always terminated by minute 

 spines, but these are sometimes so very small as to be 

 scarcely, or not at all, distinguishable from the pubescence. 

 The basal joint of the hind tarsi is as long or almost as 

 the three following joints combined. 



I have not considered it necessary to describe the 

 pubescence of each species, as it is much the same in all ; 

 that is to say, short and moderately dense on the elytra, 

 and sparse or moderately sparse elsewhere ; it appears to 

 be comparatively easily abraded. 



The sex should always be stated ; I have seen no species 

 (with the exception of dolichocephalus) in which the female 

 is sufficiently distinctive to warrant a description being 

 founded on that sex only ; in fact, the females of most of the 

 species are so closely allied in general appearances that it 

 is often very difficult to separate them. 



I have seen many other species which for various reasons 

 are not here described, and I think it probable that the 

 number now recorded will be more than doubled, and that 

 other singular modifications of the antennae will be found 

 to exist. I am acquainted with all the described species 

 excepting possibly galeatus, which is commented on below 

 They may be tabulated as follows : —
