Mr. D. Sliaip on the Elateridse of Neio Zealand. 401 



Mr. Wakefield informs me that these larvee and pupse 

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

 Christchurch. The larv^ 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 Prionoplus reticularis made short work of the latter." 



2. Ochosternus Parryi^ Cand. 



0. niger, sat nitidus, breviter et sequaliter, fere sparsim fusco 

 pubescens ; prothorace crebre fortiter puuctato, angulis poste- 

 rioribus vix divergentibus ; elytris subtiliter striatis, iuterstitiis 

 Eequahbus, subtiliter punctatis, apice subrotundatis ; antennis 

 articulis secundo et tertio brevibus, sed hoc quam illo paido 

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

 Long. 17-21 m. m. 



This species, though closely allied to Thoramus Wahefieldi^ 

 is smaller and much narrower in proportion ; this difference 

 in form is accompanied by a greater approximation of the 

 intermediate coxse, and a more complete suture between the 

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

 ture of the antennae 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 neighbourhood. 



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

 collection, named by M. Cand^ze " Ochosternus Parryi ? ;" 

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

 an opinion as to what form M. Cand^ze considered to be the 

 male of 0. Parryi. 



3. Tfioramus obscuruSj n. sp. 



T. niger, sat nitidus, breviter et sequaliter fusco pubescens ; pro- 

 thorace crebre punctate ; elytris subtiliter striatis, iuterstitiis 

 sequalibus, crebrius punctatis, apice subrotundatis ; antennis ar- 

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

 articulis 4-10. angulo apicali interno leviter producto ; interstitio 

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



This species is rather closely allied to Thoramus Walcejleldiy 

 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 forms ; 

 the false joint at the apex of the antennae 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).
