14 Mr. D. Sharp's descriptions of new species, ^c. 



planato ; elytris elongatis, minus argute puuctato-striatis ; 

 corpore subtus fortiter punctato. Long. 2^ mm. 



This peculiar species at first sight reminds one of a 

 Styphlus or Orthochce.tes ; it departs structurally in several 

 respects from Sericotrogus subcenescens, but may be at 

 present arranged in the same genus with that species ; it 

 is of more slender and depressed form ; has the rostrum 

 more slender and the head is very much smaller, so that the 

 smooth neck is continued forwards almost directly as the 

 rostrum ; the antennas are more slender, the joints before 

 the club being bead-like instead of transverse ; the lobes 

 of the 3rd tarsal joint are remarkably largely developed 

 and distinct ; and the hind cox^ are rather more distant ; 

 in Sericotrogiis suhcenescens the antennal scrobes are re- 

 markably well developed, and are continued backwards, 

 passing to the under surface of the rostrum, while in Seri- 

 cotrogus setiger they are quite small and indistinct. 



I received a specimen of this species a few months ago 

 from Captain Broun ; it was found by him at Tairua and 

 labelled 308. A second individual sent by Captain Brovm 

 at the same time, and with the same number, belongs 

 doubtfully to this species ; it is more rufescent in colour, 

 and has the setre of the u]5per surface less developed, and 

 shows also other slight differences in sculpture and struc- 

 ture.
