. Cerambycidae of Northern Asia. Cerambycidae; Beetles; Cerambycidae; Cerambycidae. 128 Egg: White, elongate, slightly curved, narrowly rounded at poles. Chorion matte, with fine, dense, reticulate (almost punctate) scu^ture. Length mm, width mm. Larva (Fig. 46): Similar to the larva of Monochamus sutor (L.). Dis- tinguished from it by location of bristles at anterior margin of pronotum, which form here a comparatively uniform transverse band, and by small spiracles on abdominal segments. Head parallel-sided, moderately flat. Epis- toma barely convex, laterally with faint front

Dis- tinguished from it by location of bristles at anterior margin of pronotum, which form here a comparatively uniform transverse band, and by small spiracles on abdominal segments. Head parallel-sided, moderately flat. Epis- toma barely convex, laterally with faint frontal sutures, medially with lon- gitudinal suture, in anterior half rusty, here with long and short bristles, at anterior margin with three lateral brisdes in transverse row. Hypostoma convex, rusty-brown, with steeply rounded anterior angles. Temporo- parietal lobes at anterior margin with dark brown fringe, here behind anten- nae with long setiform hairs forming narrow transverse band. Antennae short, projecting from antennal socket by one or two segments. Clypeus large, trapezoid, laterally with two-three short, barely perceptible bristles, basally somewhat rusty. Labrum in anterior half convex, whitish, with dense rusty bristles, at anterior margin rounded, tapering toward base, here glabrous, rusty, laterally with black spot. Mandibles black, on outer side basally with pair of deep longitudinal notches, each bearing one-four bristles, apically truncate, with elongate ventral Fig. 46. Larva of Monochamus urussovi (Fisch.). a—head and pronotum; b—^abdominal tergite with dorsal locomotory ampulla; c—first instar Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Cherepanov, A.
