The remarkably large eyes will necessitate the location of this species 
in a section apart from the others.

3823. Dimerus bisulciceps sp. nov. Dimerus Fauvel, Trans. N.Z. Inst., 
vol. 44, p. 400. 
Elongate, nitid; head and thorax light chestnut-red, elytra rufous, 
hind-body rufo-castaneous ; legs fusco-testaceous, antennae, palpi, and tarsi 
fulvescent ; the hind-body with suberect yellow pubescence. 
Head large, quite as broad as thorax, distinctly bisulcate from the front 
to beyond the middle ; irregularly, finely, but quite perceptibly punctate, 
longitudinally rugose at the sides; it bears a few fine inconspicuous flaves- 
cent hairs. Thorax a third longer than broad, a little wider before the 
middle than elsewhere, gradually narrowed behind ; broadly quadrisuleate 
from the base to near the apex, the inner pair bent outwardly in front, with 
about 8 basal and a pair of frontal punctures. Elytra slightly broader than 
long, curvedly narrowed towards the base ; they are impunctate, but have 
well-marked sutural striae. Hind-body very elongate, finely punctured, 
basal segment largest. 
Legs slender and elongate. Tarsi pentamerous, basal 2 joints of the 
anterior oblong, slightly longer than 3rd, the posterior pair very elongate 
and slender. 
Antennae |l-articulate, inserted below the sides a short distance in 
front of the eyes, 2nd oblong, fully as long as the exposed portion of the 
lst and stouter than the following 5, 9th moniliform, rather broader than 
the small 8th, 10th suboblong, the terminal larger and subacuminate. 
Mandibles falciform, as long as the head, each with a central tooth, 
but as they are directed forwards along the inside, instead of projecting 
inwardly, they may not be noticed. Eyes large, longitudinal, occupying 
fully half of the sides. 
In D. brouni Fauvel the 4th dorsal segment is much darker than the 
others, the elytral striae are indefinite, and the sculpture of the head is 
very different.

3824. Exeirarthra angustula sp. nov. Ezeirarthra Broun, Man. N.Z. 
Coleopt., p. 1054. 
Elongate, slender, nitid; castaneo-rufous, legs and antennae rufo- 
testaceous, tarsi and palpi yellowish ; pubescence greyish-yellow, elongate 
and slender, subdepressed, longer and more erect behind. 
Head smaller than thorax, distinctly obliquely narrowed in front of the 
prominent eyes, nearly straight behind them, hind angles obtuse ; finely 
and indistinctly punctate, antennal tubercles slightly elevated in front and 
separated by a narrow groove which hardly extends as far as the front of 
the eyes; it is distinctly bifoveate behind. Thorax oviform, of about 
equal length and breadth, its apex narrower than the occiput, with an
