116 FOREST ENTOMOLOGY. 



in size, from 1 to 2 mm., the characters are entirely microscopical. 

 The following generic characters may be given : 



Pronotum as broad as long, with small hump projecting in front 

 portion. Elytra slightly hairy, conspicuously punctured, and well 

 covering the abdomen. Whip of antennas four-jointed ; joints very 

 small ; club comparatively large ; tibia broad, and toothed on outer 

 edge. 



The following are the specific characters, according to Fowler 

 viz. : 



I. Club of antennae with the sutures transverse, almost straight ; 

 body behind thorax, only twice as long as broad. 



1. Eyes entire; thorax with four transverse rows of granules in 



front ..... C. tilice, Panz. 



2. Eyes emarginate on their anterior border ; thorax confusedly 



granulate. 



A. Elytra with very short, scarcely visible, hairs ; rows of 



punctures on elytra not very fine, and placed in some- 

 what impressed stria? . . C. abietis, Eatz. 



B. Elytra with long raised hairs ; rows of punctures on elytra 



very fine C. picece, Eatz. 



IT. Club of antennse with the sutures strongly curved ; body 



behind thorax three times as long as broad ; elytra without 



striae ...... C. fagi, Nord. 



Cryphalus abietis, Eatz. 



This species is found on dead spruce branches, generally at knots 

 of the branches. It is considered rare, but this arises probably 

 from its being overlooked, for I have found it in the south of 

 England, and again in the north-east of Scotland. Figs. 108 

 and 109. 



Eichhoff says it is double-brooded, as the first brood swarmed in 

 February and March, while snow was still on the ground, and the 

 second brood appeared about the latter end of July. 



I received a portion of a stem of young Douglas fir, heavily 

 attacked by this insect, from Mr A. C Forbes, Bowood, Wiltshire. 

 As a rule, this tree is almost immune from insect attacks. Mr Forbes 

 has again sent me an example of this species on Douglas fir from 

 Cockle Park, Northumberland.
