48o FAUNA HAWAIIENSIS 



We have four specimens of this obscure species. By the male characters it comes 

 nearest to A^. vagepictus, but the prosternal process is a Httle more prominent and there- 

 fore the species is an approximation to Nesopetinus, Hke N. abnorinalis and others in 

 a similar condition. I expect it will prove merely to be an ally of N. vagepictus with 

 slightly different prosternum. The thorax is narrow, slightly narrowed in front, very 

 little explanate at the sides, the hind angles nearly rectangular, the punctuation coarse, 

 in front denser and finer, everywhere so dense as to make the surface dull except for 

 a few larger interstices along the middle ; the two larger depressions are very shallow. 

 The serial punctuation of the elytra is very fine, and there is a scanty fine punctuation 

 on the interstices which are a little shining. The male pygidium is extremely slightly 

 emarginate, with very obtuse angles. 



An immature example of the female sex probably belongs to this species ; it has 

 a little less punctuation on the thorax as is the case with many other species.

Described from a single specimen by Mr Blackburn : we have now a large series 

 of this remarkable — though highly variable — species. It may always be distinguished 

 from every other Ncsopeplus by the total absence of the serial punctuation of the elytra. 

 In colour it varies from black to yellow ; with numerous varieties in the way of pattern 

 on the elytra. The head is small in proportion to the general width, the eyes are 

 prominent and have no margin at all behind them. The thorax is much explanate at 

 the sides behind, with the angles very obtuse, the punctuation coarse, and looking 

 somewhat like the surface of a file. The male pygidium is not notched at the tip, but 

 has a perceptible emargination and its angles are very rounded ; in the female the 

 pygidium is broad at the tip and very gently rounded. We have 197 specimens.

(12) Nesopephis pictits, sp. no v. 



Rufo-testaceus, supra plus minusve aenescens, tenuiter pubescens, nitidus, thorace 

 abdomineque medio nigricante, elytris fusco-aeneis, rufo-variegatis, evidenter seriatim 

 punctatis ; prothorace fortiter transverso, baud dense punctato. Long. 3^ — 4^, lat.

This species does not appear closely allied to any other. It is perhaps most similar 

 to Nesopetinus varius. The form of the prosternal process will not permit the species
