CRYPTORHYNCHIDAE. 455 
3944. Acalles dentigerus sp. nov. 
Oval, compact, convex, opaque; piceous, antennae and tarsi piceo- 
rufous ; covered with depressed yellowish - brown and pale testaceous 
squamae ; the pale ones cover the head, the basal half of rostrum, form an 
indefinite streak near each side of the thorax and a longitudinal yet short 
line at the middle of its base; there are many erect, but not elongate, in- 
fuscate setae on the thorax and near the sides of the elytra; each elytron 
behind the middle, midway between the suture and side, has a pair of crests 
formed of coarser, erect, pale setae, the larger is placed on the commence- 
ment of the hind slope. 
Rostrum nearly as long as thorax, a little expanded in front, obtusely 
ridged along the middle. Head flat between the eyes. Thorax a fourth 
broader than long, moderately but not abruptly narrowed in front, indis- 
tinctly bisinuate at the base, neither closely nor coarsely punctured. Elytra 
of the same width as thorax at the base, quite twice its length, the posterior 
slope nearly half of the whole length; they are seemingly moderately 
seriate-punctate ; on their basal portion, alongside the suture, there are 
nearly a dozen small granules, and a slight ridge just outside of the more 
central crests, on each. 
Scape medially inserted, attaining the centre of the eye, rather stout, 
gradually incrassate, bearing erect setae ; 2nd joint of funiculus as long as 
the Ist, both evidently elongate, 4th slightly longer than 3rd, joints 5-7 as 
long as broad ; club elongate-oval. 
Legs with erect squamiform setae, posterior femora with a denticle 
underneath. 
Underside with pale depressed scales. Pectoral canal deep, extending 
to front of intermediate coxae, with perpendicular, strongly curved borders 
between these. Basal segment longer than the next, broadly depressed 
along the middle, the intervening suture slightly sinuate, 5th with fine setae 
near the extremity. 
Smaller than A. veratrus (2173), with different clothing, narrower tarsi, 
ridged rostrum, and finely dentate hind thighs. In A. maritimus (2174) 
the scape is much shorter, implanted bebind the middle of the rostrum, 
which at that point is quite perceptibly dilated, its head is unimpressed, 
the thorax is shorter, and, albeit gradually, is much more narrowed an- 
teriorly. All three are placed in section 1 in my cabinet. 
Length (rostrum exclusive), 5mm.; breadth, 3 mm. 
Muriwai, west coast of Auckland. A single example found by Mr. A. E. 
Brookes, of Mount Albert, on the 13th April, 1914. 
Group CossoNIDAE. 
3945. Allaorus impressus sp. nov. Allaorus Broun, Man. N.Z. Coleopt., 
p. 1494. 
Subovate, rather elongate, moderately convex, nitid; with a few pale, 
very slender, inconspicuous hairs; the individuals vary from chestnut-red 
to piceo-rufous, those of the latter hue have the middle of the elytra piceous ; 
antennae and tarsi usually of a paler red than the legs, the club piceous. 
Rostrum stout, a little arched, a third shorter than thorax, slightly 
expanded anteriorly in the male, parallel in the female, rather finely punc- 
tate, almost smooth in front, without any transverse basal impression. 
Thorax nearly a third longer than broad, moderately and gradually nar-
