2028 ARBORETUM AND FRUTICETUM. PART I1I, 
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 falls 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 
makesits appearance. In jig. 1947., 
a shows the wound made by the 
introduction of the egg into the 
young fruit; 4, the hole in the 
mature fruit, by which the larva , 
has made its exit; cis the larva; 
d, the pupa; and e, 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 
Si g being the jaws, and / a. side 
view of a single jaw. In addition 
to this insect, Orchéstes avellanz 
one of the small flea weevils), 
Strophosémus céryli, Apdéderus 
céryli, Attélabus curculidnides, 
Tropideres _ niveiréstris, Rhyn- 
chites Bacchus, and Polydrisus 
argentatus, are found in the nut;

coccineaand hemisphe’rica; Clythra longipes, 4-punctata, tridentata, and aurita;

pectinicérnis. Amongst the Linnean Hemiptera are : Cimex céryli, avellane, 
and annulatus Linn; Cicada aurita, bicordata, and céryli; A‘phis céryli; and
