162 Capt. T. Broun on new 
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 
fyont, the dorsal groove somewhat indistinct near its extre- 
mities; near the apex there is an angulate impression ; basal 
fosse 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. Scw- 
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 stri, 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 thé 
labrum is of the same shape, the eyes are smaller, and the 
thorax is less transverse and more evidently narrowed pos- 
teriorly. 
@. Length 44, breadth 13 lines. 
Ligar’s Bush, Papakura. Two females. 
Group Feroniide. 
Pterostichus tthaginis, sp. n. 
Elongate-oblong, slightly convex, shining, black ; palpi and 
tarsi piceo-rufous, the three basal joints of the antenne 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. lytra oblong-oval, shoulders slightly 
dentiform, apices broadly rounded ; their striz: are not deep, 
they are rather finely and not regularly punctured, interstices 
eae) plane. Legs moderate, posterior femora not angulate 
below.
