NEW ZEALAND DASCYLLID. | 379 
behind, posterior angles rectangular and resting on the elytra, 
base and apex emarginated, the latter more deeply and sinuously 
than the former ; with a dorsal groove, two lateral foveze near 
the middle, and two close to the base, nearly a dozen large 
punctures, and with the surface more or less finely and irregu- 
larly punctated. Scutellwm triangular. Hlytra a little wider than 
the thorax at the base, widest near the middle, narrowed pos- 
teriorly ; each elytron with two, rather fine, punctured, sutural 
striz, and two more obvious, interrupted ones at the side, the 
intervening space bearing punctures and irregularly formed 
linear impressions. Underside of body and legs pitchy-brown, 
epipleure rufescent, without distinct sculpture. 
_ This species, especially as regards the shape of the thorax, 
comes near No. 694; it is, however, a good deal broader; the 
elytral sculpture somewhat resembles that of 4. bullatum though 
very much finer ; the scutellum is not rounded. The antenne are 
pubescent, their 3rd joint is not twice the length of the 2nd. 
Length, 5 ; breadth, 2% lines. 
The species bears the name of its discoverer, Thos. Chalmer, 
Esq., who sent me a specimen from Dunedin (Flagstaff Hill). 
CISTELIDA. 
1406. Xylochus dentipes,n.sp.—Sub-oblong, moderately convex, 
nitid, piceous, nude, legs pitely= red, tarsi fulvous, antenne and 
palpi red. 
Head contracted behind the eyes, finely and not very closely 
punctated. Prothorax transversal, base feebly sinuated, sides 
medially rounded, nearly straight behind, narrower in front than 
at the base, finely marginated ; more finely and distantly punc- 
tured than the head, with two small basal fovese. Sewtellwm tri- 
angular, minutely punctured. Hlytra rather broader and. twice 
as Jong as the thorax, almost oviform, moderately narrowed 
apically ; each with a scutellar row of punctures and eight striae, 
none distinct at the base, the intermediate more or less confluent 
or obsolete posteriorly, all punctured ; interstices but little ele- 
vated, finely punctulated. Anterior femora slender at the base, 
dilated beyond and very evidently dentate ; tib’@ somewhat dis- 
torted, so as to appear incurved or incised at the middle ; inter- 
mediate and posterior femora simple, tibize arcuated, ciliated 
with short fulvous hairs. Undersi/e nearly smooth. Female—all 
the thighs simple, front tibiz not incised. Antenne reaching 
beyond the middle femora, with yellow pubescence’; basal joint 
Shorter than 3rd, 2nd short, 3rd and 4th longest, equal, 5th and 
6th each shorter than 4th. Terminal joint of maxillary palpi 
securiform. 
I believe I am right in considering these two forms to repre- 
sent the sexes of one species, closely allied to X. tibialis, but 
differing from it in the armature of the front thighs, and in the 
absence of the basal protuberance of the femora and rounded 
median foveze of the thorax.
