66O COLEOPTERA 



stride, however, more distinct behind, they are finely punctured ; the 

 interstices are finely and densely punctate, appearing, on some parts, 

 slightly rugose. 



Differs from R. modestus (p. 80), its nearest ally, in being less 

 convex and more oblong; it has a much more densely and distinctly 

 punctate thorax, and the elytral sculpture also differs .materially ; the 

 interstices are plane, or nearly so, and their punctation seems almost as 

 distinct as that of the striae when viewed from the side. 



Length, 3 lines ; breadth, \\. 



The two specimens now before me were collected by J. D. Enys, 

 Esq., of Castle Point Station, Canterbury. 



Group-PSELAPHIDJE (P. 121). 

 Pselaphus (p. 122). 



1153. P. dulcis, n.s. Body shining, almost nude, dark-red; legs, 

 antennae, and club of palpi dull and of a paler red, the rest of the palpi 

 and the tarsi yellowish. 



Head oviform, considerably narrowed behind, deeply impressed on 

 the middle from the front to the eyes, less so on the vertex ; eyes con- 

 spicuous, coarsely facetted. Prothorax longer than broad, narrow, hardly 

 wider than the head, subovate, narrower behind than in front, very con- 

 vex, the dorsal space being laterally compressed and much elevated. 

 Elytra much broader than the thorax, rather longer, subconical, rounded, 

 narrowed, and declivous towards the base ; with a distinct sutural stria, 

 and between that and the shoulder a longitudinal carina not attaining the 

 apex; the space between these elevated lines is concave. The basal 

 segment of the abdomen about as long as and broader than the elytra, 

 broadly margined, and, like the rest of the body, without visible sculpture, 

 but bearing a few very fine short hairs ; the remaining segments are 

 deflexed, the second and third short. 



Antenncc as long as head and thorax ; basal joint stout, as long as the 

 following two united ; second much stouter than third ; joints 3-8 about 

 equal ; ninth longer than broad ; tenth broader but not quite as long as 

 the ninth ; the terminal larger than the preceding two conjointly, much 

 broader, almost cultriform, i.e., nearly straight on one side, dilated 

 towards the middle, and from thence narrowed to a point. 



Legs robust; the apical joint of the tarsi as long as the intermediate ; 

 posterior tibiae somewhat flexuose. Third joint of maxillary palpi hardly 

 as long and stout as the clavate portion of the second ; fourth rough. 



Length, i line ; breadth, |. 



One example found at Pataua, north of Whangarei Harbour. 



Bryaxis (P. 124). 



1154- B. pagamiS, n.s. Body nearly nude, the only villosity 

 visible being on the abdomen and antennae; convex, shining, elytra 

 pale red, the other parts darker, tarsi yellow. 



Head about as broad as thorax, rounded behind, and, with the excep- 

 tion of two small foveae in line with the eyes, quite smooth. Prothorax
