there. In 1873 ^^- Reed relates its appearance in enormous numbers at 

 London, Ont. ; now it appears to be generally distributed throughout this 

 province, and occasionally becomes very injurious to these ornamental 

 trees. The perfect insect, in the localities it frequents, may usually be 

 found in September on the flowers of the Golden-rod (Solidago), of which 

 it eats the pollen, as well as upon the trunks of the trees it infests. 



5. Chrysobothris femorata Fab. — An Apple tree Borer. — This insect 

 belongs to the family Buprestidae, while all the others on our plate pertain 

 to the Cerambycidse ; the difference in shape and structure, and especially 

 in the length of the antennae, is very noticeable in the figures. The 

 beetle, which may be found basking on the tree-trunks in the hot sunshine 

 in the end of June or during July, is very lively when danger threatens 

 and will take wing instantly if an attempt is made to catch it. Its black- 

 ish colour above so much resembles the bark of the tree that it readily 

 escapes the notice of an ordinary observer ; but beneath it is of a beauti- 

 fully burnished dark copper colour, looking as if it were made of metal ; 

 beneath the wing-covers it is bluish. While the figure gives the shape 

 of the insect very correctly, it much exaggerates its size, which seldom 

 exceeds three eighths of an inch ; the light spots on the wing-cover are 

 also erroneous in being very much too conspicuous. The larva is a long 

 flattened grub, with an enormously large flat head in proportion to the 

 rest of its body. When first hatched from the egg it eats the soft sap- 

 wood of the Apple tree, but afterwards it bores into the harder interior. 

 As it especially attacks young trees, it is often terribly destructive to 

 newly-planted orchards. 



6. Saperda ca7idida Fab. — An Apple tree Borer. — This insect, which 

 rivals the foregoing species in the injuries it inflicts upon Apple trees, is a 

 pale-brown beetle with two chalky-white longitudinal stripes running from 

 the head to the apex of the wing-covers ; its under side, legs and face are 

 also chalky-white, and its antennse a little darker ; its length is about 

 three-quarters of an inch. The larva is of a pale yellow or whitish 

 'colour, with a brownish polished head and black jaws ; it is destitute of 

 legs, but like other larvae of the same family, it is enabled to move in its 

 burrows by the contraction and expansion of its well-defined segments ; 

 when fully grown it is about an inch long. It may readily be distinguished 

 from the preceding species by its cylindrical and more symmetrical shape.
