Mr. 1). Sliav]wi?j the Elatcrida'' of Neio Zealand . 401 



Mr. AVakcficld informs me that these larva? and pupa? 

 " were taken from a fallen log of matai or black pine, near 

 Chriatcliurch. The larva? were abundant in the log. I cut 

 several perfect insects out of the same tree. The larva is very 

 fierce ; and one which I took home in the same box with a 

 larva of Prionoplu.s reticularis made short work of the latter," 



2. Ochosternus Parry i^ Cand. 



0. nip;cr, sat nitidus, brcvitcr et ffiqualitcr, fere eparsim fusco 

 pubescens ; prothorace crebre fortitcr punctato, angulis poste- 

 rioribus vix divergentibiis ; elytris subtiliter striatis, interstitiis 

 ttqualibus, subtiliter punctatis, apice subrotundatis ; antennis 

 articulis secundo et tertio brevibus, sed hoc quam illo paulo 

 longiore ; intcrstitio meso-coxali angusto, sutura minus distincta. 

 Long. 17-21 m. m. 



This s])ccie8, though closely allied to Thoramus Wakejieldi\ 

 is smaller and much narrower in proportion ; this difference 

 in form is accompanied by a greater approximation of the 

 intermediate coxa?, and a more complete suture between the 

 middle processes of the meso- and metasternuni. The struc- 

 ture of the antennas is similar in the two species. 



Christchurch, found by Mr. Wakefield, but only three 

 specimens ; a fourth very small individual has been discovered 

 by Mr. Fereday in the same neiglibourhood. 



Obs. Several specimens of this species are in Mr. Janson's 

 collection, named by M. Candbze " OcJiosternus Parryi $ ;" 

 but I have seen no specimen which would enable me to form 

 an opinion as to what form M. Candtjze considered to be the 

 male of 0. Parryi. 



3. Thoramus obscurus, n. sp. 



T. niger, sat nitidus, brcvitcr et ajqualiter fusco pubescens ; pro- 

 thorace crebre punctato ; elytris subtiliter striatis, interstitiis 

 sequalibus, crebrius punctatis, apice subrotundatis ; antennis ar- 

 ticulis secundo et tertio brevissimis, hoc quam illo paulo breviore, 

 articulis 4— Kb angulo apicali interne leviter producto ; interstitio 

 meso-coxali lato. Long. 19-21 m. m. 



This species is rather closely allied to Thoramus Wahejieldiy 

 but is smaller and less elongate in form ; this, in conjunction 

 with the rather broad intercoxal space, the very abbreviated 

 third joint of the antenna;, and the evenly distributed pubes- 

 cence, will readily distinguish it from the other allied torms ; 

 the false joint at the apex of the antenna? is rather elongate, 

 and very distinctly marked off. 



Found by Mr. Wakefield near Christchurch (three speci- 

 mens?), and at Akaroa, Dec. 19, 1874 (one specimen).
