488 FAUNA HAWAIIENSIS 



(25) Nesopeplus sp. ? 



In Mr Perkins' collection is a single female specimen which does not appear to fall 

 definitely within the limits of any of our species. It appears to be closely allied to 

 N. cognatits but has the thorax proportionately broader and more rounded at the sides, 

 in that respect approaching somewhat to N. tcstaceipes. It resembles A^. cognatits in 

 size and coloration and in the form of the pygidium. It is from the Waianae mts., 

 Oahu, about 3000 ft. (no. 547, Perkins). H. S.

(26) Nesopeplus koelensis, Blackburn. 



B r achy pep 1ms koelen sis Blackburn, Tr. Dublin Soc. in. 1885, p. 133. 



This narrow and convex species was described from a single male obtained by 

 beating flowers at Koele, at 2000 ft. elevation. We now have about i 20 specimens. 

 The prothorax is characteristically shaped, being convex, rather long in proportion to its 

 breadth, slightly narrowed in front, with the sides posteriorly sinuate and the hind 

 angles sharp and definite, almost right angles ; its punctures are not deep, and decidedly 

 scanty, but vary considerably in number, being distinctly more numerous in the male 

 than in the female ; there is often a very slight depression on the posterior part of the 

 disc. On either elytron is a testaceous patch, which varies in extent, being sometimes 

 much obscured. The punctuation on the abdomen is somewhat scanty. The length 

 varies from 2| to 3^ mm. 



The male pygidium has a conspicuous notch with rounded outline, and a sharp 

 prominence on either side ; last ventral segment with a wide shallow emargination 

 fringed with short hairs ; supplementary segment emarginate with a rounded prominence 

 on either side ot the notch. Female pygidium somewhat narrow, at the ape.x depressed 

 and with a rounded emargination (which is variable, being sometimes very slight); last 

 ventral segment extremely slightly bisinuate.
