COLEOPTERA 



All 



Similar to the paler, more densely and finely punctate varieties of A^. inaiiratiis, 

 but with the sides of the thorax more rounded and more strongly narrowed in front ; 

 the length of the thorax is rather greater, and it is very densely punctate. The sides of 

 the thorax are broadly explanate behind. 



In the male of this species there is only a slight emargination of the apex of the 

 last dorsal plate, and the hind angles project very little and are not sharp or tooth-like. 

 Twenty-five specimens.

(5) Nesopeplus olindae, Blackburn. 



Brachypepbis olinda Blackburn, Tr. Dublin Soc. iii. 1885, p. 132. 



Fusco-testaceus, vix metallescens, elytris testaceis fusco-variegatis ; thorace lateribus 

 rotundatis, angulis posterioribus obtusis, crebre punctato. Long. 4 mm. 



I think this is the species Mr Blackburn described under this name. It is true 

 that he says the thorax is not explanate at the sides, while the sides are quite 

 distinctly explanate ; but I find that his type in the British Museum agrees with our 

 specimens, though unfortunately it is not in good condition. The male pygidium has 

 a shallowy notch at the apex with the angles prominent and acute, but not so markedly 

 as in N. se^nis. 



The species seems to be very variable and I assign to it a short series coming 

 from several islands, and differing much as regards coloration. The females too have 

 the thorax more distinctly punctured than the males. 



From both N. segiiis and N. anticatiis the species differs in the thorax being 

 less narrowed in front, and more densely punctured. In the structure of the male 

 pygidium it is intermediate between the two. Forty-five specimens.

(6) Nesoptpliis scgtiis, sp. nov. 



Fusco-testaceus, supra metallescens, antennarum basi pedibusque testaceis ; protho- 

 race lateribus rotundatis, anterius fortiter angustato, angulis posterioribus obtusis, dense 

 punctato ; elytris subtilius seriatim punctatis. Long. 3-^, lat. \\ — 1\ mm. 



The male has a much denser punctuation of the thorax than the female. The 

 species comes very near to N. anticatus but has the thora.x more strongly rounded at 

 the sides, and the male characters are distinctly different, the emargination of the 

 pygidium being deeper and the angles more sharp. This character distinguishes 

 A^. segnis from all the species that are very similar to it, and brings it near to A", bidens.
