DESCRIPTION OF C. ABIETIS RATZ. The following is Fowler's^ description: C. abietis Ratz. (Fig. 1). Oblong, subcylindrical, compressed and verv convex: fuscous or fuscous-brown, dull, antennae and legs reddish-. Fig. 1. Adult of Cryphalus abietis Ratz. (greatly magnified). brown, club of the former usually darker, rounded at apex: thorax subglobular, very finely punctured at sides and behind, front part confusedly granulate: elytra rather more than double as long as thorax with distinct punctured interstices, covered throughout with extremely short scale-like hairs, and also very diffusely with short erect hairs, which are wanting behind: the colour of the antennae and the legs is somewhat variable: the species may easily be recognised by the tubercles on the anterior portion of the thorax being few in number and irregular in their distribution and by the regular comparatively strong rows of punctures and very short pubescence of the elytra. Length 1-2^ mm. My own examination of numbers of C. abietis leads me to emphasise the following characters: (1) Club of antennae rounded at apex, antennal funicle four-jointed (Fig. 2).
