Acromacer Kuschel, 1989 : 152. Genus Acromacer Kuschel This genus contains one species. The genus is readily recognized by the dorsally smooth rostrum, which is inserted on the lower portion of the head at a nearly right angle to the frons and by a labrum, which tapers to a point and has no peg-like apical setae. It differs from Cimberis by the unarmed inner edge of the mandibles and fromPityomacerby (in addition to the characters mentioned in the key to genera) the labrum, which is trapezoidal or broadly rounded at the apex with 6 peg-like apical setae. Description. Head not retractile to eyes. Frons wider than rostrum at apex. Eyes small, round, strongly convex. Rostrum moderately slendeq strongly curved, without carinae. Antennae inserted about midpoint of rostrum; insertion point distant from mandibular sockets by less than length of scape in males or by more than length of scape in females; scrobes shallow. Mandibles inserted laterally; sockets fully visible in dorsal view; mandibles angulate on lateral margin, unarmed on inner margin. Pronotum wider than long, truncate or emarginate at apex; surface of pronotum deeply punctate. Elytra elongate, covering pygidium. Abdominal sternites lacking setaceous pits in both sexes. Type species. Rhinomq.cer bombifrons LeConte, original designation and monotypy. Ac ro mace r bo m bifro ns (LeConte) Fig.40 Rhinomacer bombifrons LeConte, t876:412 (holotype, British Columbia; MCZ): Hatch I97I:337. Cimberis bombifrons : Hamilton 1969 :57 . Neocimberis bombifrons: O'Brien and Wibmer 1982:18. Acromq,cer bombifrons : Kuschel 1989: 153. Description. Length 2.8-5.4 mm. Integument of head, pronotum, and rostrum dark brown; elytta, legs, and ventral surfaces lighter brown. Pubescence light brown. Head strongly convex just above eyes, weakly flattened just above base of rostrum. Frons nearly at right angles to base of rostrum and 1.4-1.6 times wider than rostrum at apex: surface shining, with rather large, deep punctures, each bearing 1 moderately long, erect, light brown seta. Rostrum2.6-3.7 times longer 64
than wide at apex, weakly curved; sides gradually diverging to apex; surface smooth, with a few scattered, impressed points' Pronotum about 1.2 times wider than long, widest just behind middle; sides moderately to strongly arcuate; disc evenly convex; surface shining and densely, deeply punctured; setae brown, abundant, semirecumbent. Elytra about 1.5 times longer than wide and densely, randomly punctured; setae brownish. erect. abundant. Abdominal sternites unmodified. Distribution. British Columbia and Alberta, south in the western United states to california and Nevada. Alberta: Banff. British Columbia: Canal Flats, Cariboo, Chilcotin, Clinton, Indian Meadows, "O'Keefe," Riske Creek, "sorenson Lake," and "Spious Creek." Comments. Adults of this species can be readily distinguished from those of other species in the family by the abrupt angle of the junction of the rostrum with the head (Fig. 40) and by the fact that the female lacks tufts of setae on the abdominal sternites. Nothingis known of the biolory or life history of this species. Hamilton (1969) reports on a single adult collectedonPinus species in California. Kuschel (1989) lists lodgepole pine (Pinus contorta) and Jeffrey pine (P jeffreyl) as hosts. Pityomacer Kuschel, 190: l-45. Genus Pityomacer Kuschel Three species are included in this genus by Kuschel (1989), one of which occurs in western Canada. Members of this genus are distinguished from those in Acromacer and Cimberls by the granulose pronotum and by characters of the male genitalia. See Kuschel (1989) for details of these differences. In addition, members of Pityomacer differ from those in Cimberis by the antennae inserted closer to the middle of the rostrum and by mandibles that are angulate on the outer margin and unarmed on the inner margin. Members of this genus are distinguished from those in Acromacer by the distinct punctures on the dorsum of the basal portion ofthe rostrum and by other characters ofthe mouthparts. Description. Head not retractile to eyes. Frons less than 2.0 times widei than rostral apex. Eyes small, round or slightly oval, strongly convex. Rostrum slender, widened at apex, weakly curved, with 3 carinae or smooth lines separated by 2 rows of punctures' Scrobes shallow. Antennae distant from mandibular sockets by about combined length of first 2 antennal segments. Mandibles inserted laterally; mandibular sockets partly exposed in dorsal view; sides of mandibles angulate on outer margin, unarmed on inner margin. Pronotum shallowly to deeply emarginate at apex, wider than long; surface of 65
