3944. Acalles dentigerus sp. no v. 



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 fiat 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 fimiculus as long as 

 the 1st, 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), witli different clothing, narrc^wer tarsi, 

 ridged rostrum, and finely dentate hind thighs. In A. maritimus (2174) 

 the scape is much shorter, implanted behind 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 naiiowed an- 

 teriorly. All three are placed in section i in my cabinet. 



Length (rostrum exclusive), 5 mm. ; 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. AUaorus Broun. Man. N.Z. C'oleopt., 

 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 inipressit»n. 

 Thorax nearly a third longer than })road, moderately and graduallv nar-
