418 A SECOND NOTE ON THE CARENIDES, 



A SECOND NOTE ON THE CARENIDES, WITH 

 DESCRIPTIONS OF NEW SPECIES. 



By Thomas G. Sloane. 



Having ten new species to add to the Carenides, it has seemed 

 to me a fitting opportunity to review the classification of the 

 group, as far as the material at present in my hands will allow of 

 my so doing. 



Five years ago I drew up a synoptic table of the different 

 genera into which the Carenides had then been divided.^" This 

 table as I recognised at the time was far from being satisfactory, 

 therefore in the present paper another tabular list of the principal 

 genera of the group is attempted, which, though evidently defective 

 in many points, seems founded on more natural characters and 

 freer from artificiality than the former. The genera Epilectus, 

 Trichocarenum and Eutoma have not been included in the table ; 

 the two former because no example of either has yet come under 

 my notice ; the last because, as yet, I have been unable to find 

 any satisfactory characters to separate it readily from the quadri- 

 piiiictatum group of the genus Careiiiwi, although it seems too 

 useful and well known a division of the Carenides to be merged 

 with Carenum. Sir William Macleay's genera Carenoscaphus, 

 Ccdliscapterus, and Platythorax, with the sub-genera Chariscap- 

 terus and Paliscaphus formerly suggested by me, are now again 

 united with the central genus Carenum. 



It seems only necessary to add that the digitation of the 

 external side of the anterior tibise does not seem to me of sufficient 

 classificatory value in the Carenides to warrant its being used as 

 a character on which to found genera.
