Bionomics of Cryi)haliis abietis 



(4) scutellum small punctiform, (5) elytra not excavate at apex, clothed 

 with a scale-like pubescence and sometimes in addition with fine raised 

 hairs. 



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).
