angles are not at all rounded off; base widely incurved, 

 without distinct margins in the middle, posterior angles very- 

 much rounded ; lateral margins more flattened behind than in 

 front, the dorsal groove somewhat indistinct near its extre- 

 mities ; near the apex there is an angulate impression ; basal 

 fossEe elongate, situated midway between the middle and the 

 sides ; in front of these, but nearer the sides, there are two 

 shallow curvate impressions; the space between each fossa 

 and the hind angle is flattened and feebly punctured ; on each 

 side, before the middle, there is a setigerous puncture. Scu- 

 tellum large, subopaque, densely and minutely sculptured. 

 Elytra ovate-oblong, obliquely sinuously narrowed posteriorly ; 

 base smooth, distinctly marked off, much incurved near each 

 side for the accommodation of the thoracic angles, which, 

 however, do not extend to the shoulders ; with deep, regular, 

 apparently impunctate strias, scutellar grooves distinct ; inter- 

 stices a little convex, moderately broad, the third with two 

 punctures, one is subapical, the other is placed before the 

 middle. 



There is but one similar species, D. maura; in it th^ 

 labrum is of the same shape, the eyes are smaller, and the 

 thorax is less transverse and more evidently narrowed pos- 

 teriorly. 



$ . Length 4j, breadth 1| lines. 



Ligar's Bush, Papakura. Two females. 



Group Feroniidae. 

 Pterosfichus ithagims, sp. n. 



Elongate-ohlong, slightly convex, shining, black ; pal]ji and 

 tarsi piceo-rufous, the three basal joints of the antenna piceous 

 and glabrous. 



Head narrowed behind ; eyes moderately prominent ; 

 mandibles feebly striate above. Thorax only about one sixth 

 broader than long, its apex usually subtruncate, the base 

 medially emarginate ; it is very little wider near the front 

 than it is at the middle, its sides very gradually narrowed 

 posteriorly, with a slight sinuosity near the base, hind angles 

 not projecting, rectangular ; the surface is very feebly trans- 

 versely striated, the median furrow is well-marked and hardly 

 at all abbreviated, the basal impressions are well-defined and 

 moderately broad. Elytra oblong-oval, shoulders slightly 

 dentiform, apices broadly rounded ; their striaj are not deep, 

 they are rather finely and not regularly punctured, interstices 

 nearly plane. Legs moderate, posterior femora not angulate 

 below.
