498 FAUNA HAWAIIENSIS 



base of the elytra; the disc has an extremely slight depression behind the middle. The 

 elytra have a very vague red patch behind the scutellum : the series of punctures are 

 fine, but distinct, the interstitial punctuation very fine.

(13) Nesopctimis celatiis. Sharp. 



Brachypeplns celahis Sharp, Tr. Dublin Soc. in. 1885, p. 134. 



This species was described from a single male specimen. We have now a very 

 variable series of about 60 specimens. The majority are very dark, with brassy 

 reflection, with the legs, antennae and lateral margins of the prothorax near its hind 

 angles, testaceous. Some specimens are of a dark reddish-testaceous, and some darker 

 ones have the central parts of the elytra of this colour. The punctuation is somewhat 

 coarse on both upper and lower surfaces. The thorax is somewhat long in proportion 

 to its width, narrow, convex, narrowed in front, with the sides explanate only posteriorly 

 (not towards the anterior angles), and the hind angles rounded. 



The male pygidium is emarginate, the angles forming short prominences : supple- 

 mentary segment very slightly rounded, almost truncate. Female pygidium short, with 

 lateral margins slightly sinuate, rather broad and rounded apically ; longitudinally 

 somewhat curved and depressed apically. The larger individuals are about 3^ mm. 

 long, while a few are very small, one male being only 2^ mm. long. 



The form of the thorax (apart from the generic difference in the prosternum) 

 distinguishes this species from Nesopeplus inauratus. The thorax is longer pro- 

 portionally, narrower, less rounded laterally, with larger and less close punctures, more 

 rounded hind angles, and the sides only explanate posteriorly.

(14) Nesopetimis apertiis, Sharp. 



Brachypeplns apertus Sharp, Tr. Dublin Soc. iii. 18S5, p. 135. 



This was described as a distinct species from a single lemale found by Mr Blackburn. 

 Mr Perkins has only found one specimen, also a female, and though we can find no 

 very important character distinguishing apertus from celatiis, yet they are probably 

 distinct. 



Both specimens are rather long and narrow, with somewhat long elytra. The 

 prothorax is very convex, and in the second specimen conspicuously narrowed in front. 

 The punctures are large, and on the prothorax rather distant. The surface is remark- 

 ably shining ; the pubescence is very scanty, especially on the prothorax and elytra,
