T)\ Sylvius has the head of moderate size in both sexes, with 

 prominent eyes, and very small, rapidly narrowed, posterior orbits. 

 The thorax is arcuate-emarginate on the fore margin, with rounded 

 anterior angles, quite as broad at the base as at the apex, and moderately 

 dilate-rotundate at a short distance behind the anterior angles. The 

 elj^tra are dentate at the humeral angles, the punctures in the striae 

 are small and distinct, and the interstices become flatter towards the 

 apex. 



Peel Forest, S. Island (C. M. Wakefield). 



Pteeostichus (Holcaspis) integratus, 



Elongatus, niger, supra cuprescens ; thorace qtiadrato, inox ante hasinfortiter 

 angustato, angulis acutis : elytris oblongo-ovatis, elongatis, striis vix punctulatis, om- 

 nino integris, septima apicem versus fortius impressa. Long. 9 lin., <J $ . 



Very closely allied to Pt. vagepunctatus (White); differing chiefly 

 in the strisB not being interrupted, and in the 7th stria being deepened 

 into a flexuous sulcus, extending from two-thirds its length to the apex. 

 The elytra are rather more narrowed to the base, and consequently 

 more oval than in Pt. vagepunctatus, and the hind femora of the ^ are 

 not dilated on their under surface.

Pteeostichus (Ehttisternus) puella, Chaud., Bull. Mosc, 1865, 



No. 3, p. 4i. 

 Captain Broun has recently sent examples of this Australian 

 species from Tairua, both to Mr. Wakefield and Dr. Sharp, which bear 

 the closest resemblance to specimens, with which I have compared them, 

 from Queensland. 



Anchomenus (Platyxus) otagoensis. 



Elongatus, deplanatus, nigro-piceus, opacus ; antennis, palpis, pedibnsque omnino 



melleo-fulvis : lahro late emarginato ; cello haud sulcata : thorace elongato-quadrato, 



postice longe, sinuatim sed modice angustato, angulis posticis suiacutis ; supra im- 



punctato, utrinqne linea ctirvata paulo impressa a hasifere ad marginem anticum 



ducta : elytris plants, elongato-ovatis, prope apicem fortiter sinuatis, apice suturali 



obtuso, sub truncal is ; supra subtiliter striatis, interstitiis plants. 



Long. 5 lin., <? ? . 



Allied to A. deplanatus (White), from which it is at once dis- 

 tinguished by the tawny-yellow colour of antennae, palpi, and legs. 

 Prom other allied species it is distinguishable by the form of the 

 thorax, which is not at all strongly narrowed behind, but gradually 

 and slightly, the anterior part of the sides being also gently rounded :
