tarsi, and by there being but one orbital seta. I have not yet alluded to the con- 
dition of the antennze, because these are in a singularly doubtful condition as to 
the pubescence of the basal joints; the first is free from pubescence ; the rather 
elongate second joint is scantily pubescent on the apical part; the third joint is 
very elongate, and is glabrous at the base, pubescent elsewhere, the following 
joints being closely pubescent ; thus the second and third joints show a gradual 
transition from the glabrous to the pubescent condition. The form of the male 
tarsus is an affinity with Pogonus. The position in the New Zealand Catalogue 
will be between the Pterostichini and Harpalini. It should be remarked that 
in this genus the mandibular seta is of little importance; always very feeble, it 
appears to be occasionally entirely absent from one or the other mandible. 
Zolus helmsi, n. sp.—Piceo-castaneus, antennis rufis pedibus castaneis; pro- 
thorace anterius fortiter rotundato, basi truncato, ante basin punctato, utrinque 
prope latus argute plicato; elytris profunde striatis, utrimque versus apicem plica 
eleyata, interstitio tertio obsolete tripunctato. Long 8mm. (Plate xu, fig. 11.) 
The head is quite short, deeply impressed on each side between the eyes, 
which are rather large. The antenne are slender and rather long, each joint being 
much longer than broad, and the second joint about as long as the basal. ‘The 
thorax is not much broader than long, with rectangular hind angles, and broader 
at the base than at the front margin. Very near the lateral margin at the base 
there is a very distinct straight plica, and within this plica the surface is depressed, 
uneven, and punctate, the punctuation not quite reaching the plica itself. The 
median channel does not reach the front, but extends to the base, though indistinct 
behind, owing to the sculpture there. The striation of the elytra is regular, and 
there is a striole near the scutellum. The’striz are not punctate, the interstices 
are flat, the plication behind very distinct. The first of the three punctures on 
the third interstice is placed as far forward as the termination of the scutellar 
stria, the second as far behind it as it is from the base, while the third is remote, 
placed at about two-thirds of the length. 
Greymouth. Helms, No. 276. I have much pleasure in connecting Mr. Helms’ name with this 
interesting form. Some years ago I received a specimen from him which I could do nothing with as it 
was a female ; after waiting a long time he has been able to send me the male. 
SYMPIESTUS (noy. gen. Pterostichinorum). 
Labrum very short, deeply emarginate, so that its angles are prominent. 
Mandibles rather elongate, little curved, with external seta. Palpi with the ter- 
minal joint a little incrassate, oval and acuminate, that of the maxillary palpi 
twice or three times as long as the penultimate joint, which is much abbreviated ;
