OP NEW ZEALAND. 1441 



Head quadrate, not narrowed anteriorly, finely granulate. Eyes 

 prominent, without coarse setae. Antenna sparsely pubescent ; first 

 joint scarcely visible above ; second stout, hardly any longer than 

 the third; joints 4-6 longer than broad ; seventh and eighth shorter ; 

 ninth a good deal larger than the preceding one ; club large, its basal 

 joint rather broader than the terminal one. Thorax longer than 

 broad, very little wider near the front than it is elsewhere, its sides 

 moderately explanate, with minutely serrate margins ; the surface 

 is finely granulate, and bears rather fine setae ; there is a depression 

 on the middle (expanded near the base), which nearly reaches the 

 apex ; at the base, not far from the middle, there are two elongate 

 depressions ; its sides, and the base, are fringed with fine setae. 

 Elytra rather long, wider than the thorax at the base only, scutellar 

 region depressed, the surface a little uneven ; they bear almost quite 

 regular series of small, distinctly-separated tubercles ; the setae are 

 somewhat concentrated on the hind slope and the basal elevations. 

 Legs finely setose. 



Underside opaque, fusco-piceous, with granular sculpture and 

 fine setae. Antennal furrows well marked, nearly straight. Pro- 

 sternum slightly, but widely, emarginate in front, its flanks unim- 

 pressed. Posterior coxa not widely distant. 



A rather narrow species, easily identified by the elytral sculpture. 

 C. graniceps may be at once separated by its acutely-rnucronate 

 tibiae. 



Length, \\ lines ; breadth, nearly \ line. 



Ashburton. Two individuals, found by Mr. W. W. Smith. 



Heterargus (Gen., p. 1085, Part V.). 



2500. H. serricollis, n-s. Oblong, moderately convex, opaque, 

 subglabrous ; elytra fuscous, the other parts reddish. 



Head apparently punctate. Antenna short, their two basal joints 

 stout, cylindric, the exposed portion of the first as long as the second; 

 third longer than broad ; 4-8 bead-like ; ninth broader than the 

 eighth ; club abruptly biarticulate. Thorax transverse, widest near 

 the front, narrowed behind, the sides moderately curved, somewhat 

 explanate, with serrate margins ; the base sinuate towards the sides, 

 so that the hind angles do not touch the elytra; its surface is 

 covered with small granules, it is a little uneven, having two indis- 

 tinct transversal impressions. Elytra oblong, rather wider than the 

 base of the thorax ; with regular series of small tubercular or granular 

 elevations, these are well defined, but should be examined from the 

 sides, two rows, near the middle of each elytron, are just perceptibly 

 more distinct than the others; the lateral margins bear rows of 

 tubercles. 



The serrate thorax, with ten or twelve small indentations at each 

 side, and the better-defined elytral sculpture, differentiate this from 

 H. rudis. 



Length, 1J lines ; breadth, nearly line. 



Capleston. One only, kindly forwarded by Mr. A. T. Cavell.
