the classical Grecian fable of the beautiful lo who, having incurred the displeasure of the 

 jealous Juno, was placed by her under the watchful vigilance of the hundred-eyed Argus. 



The under side of the wings is of the same deep yellow — the forewings having the inner 

 margin broadly shaded with purple and shewing the rcniform eyed spot very distinctly ; the 

 hinder wings are more uniform in colour, with a transverse purple line, and a very small 

 distinct white spot representing the centre of the large spot on the upper side. The body is 

 also deep yellow — somewhat darker on the thorax. The antennae, as usual in the males of 

 the bombyces, are beautifully pectinated, presenting a double comb like appearance The 

 male varies slightly in size, from two and a half to two and three-(|uarter inches in width. 



''"«■ *• ^^^^^ The female (Fig. No. 4) is 



considerably larger, ranging from 

 three to three and a half inches. 

 The specimens vary mucli in 

 colour, from a dark purplish 

 brown to a warm ochreous red. 

 The fore wings have similar 

 wavy zig-zag lines, the reniform 

 blotch being less distinct than 

 that in the male ; the inner mar- 

 gin is of a deeper colour, and 

 with the head and thorax is 

 thickly coated with a short, 

 woooly, pilose covering. The 

 hind wings are marked in a similar manner to those of the male. The undersides of the 

 wings have the same uniform colour, and are marked much like those of the male. 



The body is ochreous yellow, a little lighter above, and each segment is bordered with a 

 narrow, reddish band. 



" The moths have a fashion of sitting with their wings closed, and covering the body like 

 a low roof, the front edge of the underwings extending a little beyond that of the upper wings, 

 and curving upwards." 



The eggs are deposited on the under side of the leaf, and are described by Mr. Riley as 

 being compressed on both sides and flattened at the apex, the attached end smallest. Their 

 colour is cream white with a small black spot on the apical end and a larger orange one on the 

 sides. A cluster found on Sassafrass by a western lady contained about thirty eggs. The 

 moths are nocturnal, flying only by night. 



The Flat-Headed Apple-Tree Borer. 

 Ghrysohothris femoraia, (Fabr), 



Order, Coleoptera ; Family, Buprestid^ 



Among apple-growers there has been during the past year or two a great complaint of 

 some borer infesting their trees, and investigation has shown that it is to this little beetle that 

 the injuries may be traced. 



Fix. V Although insignificant in size, yet its larva is capable of doing immense mischief 



in our orchards. The beetle belongs to a fiimily of insects which is especially 

 remarkable for their rich and varied colouring, many having most brilliant tints, 

 'llie one we are describing, fig. 5, is of a greenish bra.ssy black colour above, the 

 under side having a bright coppery hue. It is about half an inch in length. 

 It is of an oblong oval shape, blunt round head, and tapering towards the taU. 

 It flies by day and is very swift on the wing. It may often he seen during the 

 summer months running up and down the trunk and limbs of trees or resting itself, basking 

 in the sunshine. 



The larva, fig. 6., is a pale yellow, footless grub, its anterior end being enormously 

 enlarged, round and flattened. Dr. Fitch worked up the history of this little pest some 

 years ago. Accordiusr to his account " the parent beetle deposits its egg on the bark 

 from which a worm hatches and passes through the bark, and during the cjirlier stages of
