Considerably larger than the typical species (2333). The general 

 contour is almost uninterrupted from the posterior femora to the front 

 of thorax, which in shape differs from that of the other species.

Broken Kiver, Canterbury. Described from a single female found 

 by Mr. J. H. Lewis, who also secured the male, which, hoAvever, I have 

 not seen. 



3181. Zabronothus aphelus sp. no v. 



Oblong, slightly convex, moderately nitid ; black, legs rufo-castaneous, 

 antennae, palpi, and tarsi of a lighter hue 



Head subovate, evidently narrower than thorax, without definite 

 frontal impressions. Labrum rufescent, transversely quadrate. Thorax 

 slightly broader than long, apex widely incurved, with obtuse angles; its 

 sides finely margined, gently rounded, very feebly sinuate behind, pos- 

 terior angles rectangular but not acute, the base widely emarginate and 

 resting on the elytra; the central groove does not attain either the base 

 or apex; the basal fossae are sulciform, only moderately impressed, and 

 are situated midway between the middle and sides; the surface is not 

 perfectly smooth, but there is no obvious sculpture. Elytra oblong-oval r 

 more than double the length of the thorax, and, owing to the slightly 

 dentiform shoulders, rather wider than it is at the base; their sides are 

 finely margined and a little curved; near the extremity they are some- 

 what rufescent, but scarcely at all sinuate; on each elytron there are 

 7 impunctate sharply marked dorsal striae; these extend from the 

 basal margin to the apex; interstices simple, broad and plane; the serial 

 punctures between the lateral margin and the 8th stria are nearly absent 

 at the middle. 



Manifestly smaller than the other species, most nearly approximated 

 to Z. oblongus (3025), but narrower, the thorax less transversely quad- 

 rate, with more definite posterior angles, more narrowed in front, and 

 with better-marked basal foveae.

 p. 1024. 



Elongate, moderately nitid; pubescence greyish, fine but distinct, 

 thicker on the elytra than it is elsewhere; head and thorax pale fusco- 

 rufous, elytra light brown, abdomen dark fuscous, legs and basal five 

 joints of antennae testaceous. 



Head rather broad, not perceptibly narrower than thorax, finely yet 

 distinctly but not closely punctate. Eyes large, not prominent. Thorax 

 of equal length and breadth, about a third narrower than the elytra, its 

 base rounded, the sides nearly straight; it is moderately closely and 

 distinctly punctured, but without other impressions. Elytra nearly 

 twice the length of thorax, their shoulders rounded, the punctation a 

 little coarser but more distant than that of the thorax. Hind-body 

 elongate, rather finely and distantly sculptured. 5th segment smooth on 

 the middle. 



Antennae distinctly pubescent; 2nd joint elongate but stout; 3rd 

 more than half the length of 2nd, with a slender basal stalk ; joints 4-8
