ARBORETUM AND FRUTICETUM, 



PART 111. 



the tree, eats a hole through the shell with its strong jaws, and pushes itself 

 through the aperture thus made ; although it appears too small to admit 

 the body, which contracts itself to get through, and then foils to the ground, 

 having no legs to support itself on the husk. Legs, however, would be an 

 incumbrance to the insect, as it is born in the midst of its food ; and when 

 this is consumed its feeding time has terminated, and it is ready to make its 

 way into the earth ; where it forms an oval cell, and changes into a pupa ; 

 soon after which the perfect insect 

 makes its appearance. Infg. 1947., 

 a shows the wound made by the 

 introduction of the egg into the 

 young fruit; b, the hole in the 

 mature fruit, by which the larva, 

 has made its exit; c is the larva; 

 d, the pupa ; and c, the perfect in- 

 sect (these last three figures being 

 represented about one third larger 

 than the natural size). The tip of 

 the rostrum, magnified, is shown at 

 /; g being the jaws, and h a side 

 view of a single jaw. In addition 

 to this insect, Orchestes avellanae 

 (one of the small flea weevils), 

 Strophosomus coryli, Apoderus 

 coryli, Ate'labus curculionides, 

 Tropideres niveirostris, Rhyn- 

 chites Bacchus, and Polydrusus 

 argentatus, are found in the nut ; 

 as well as the following, belonging to the Chrysomeliclae : Chrysomela 

 coccinea and hemisphae'rica ; Cl ythra longipes, 4-punctata, trident ata, and aurita ; 

 Cryptocephalus bipunctatus, cordiger, coryli, and G-punctatus ; and Hispa 

 pectinicornis. Amongst the Linnaean Hemiptera are : Cimex coryli, avellanse, 

 and annulatus Linn; Cicada aurita, bicordata, and coryli ; A v phis coryli; and 

 Coccus coryli. Hemerobius hirtus, amongst neuropterous insects ; and 

 Allantus coryli, amongst the saw-flies, complete the list of the chief species 

 of insects which feed upon the common nut.
