114 [October, 



The female moth seems to deposit her eggs in patches (there were more than 

 fifty together in one patch sent me by Mr. Ross) ; and they are arranged very closely 

 and evenly, touching one another, firmly cemented together, and covered over with 

 the long fibre-like scales from the maternal anal tuft : the egg is oblong, standing 

 upright on end, almost cylindrical, but somewhat squared by being sqeezed closely 

 against the other eggs with which it stands, the upper end convex, the lower more 

 flattened ; the shell smooth and glossy ; the colour olive-brown, browner on the top, 

 without much change ; the larva escapes by eating a round hole through the top of 

 the egg, and is at first yellow in colour, the internal vessels showing faintly blackish 

 down the back, and there is a fine blackish sub-dorsal line ; the usual dots very 

 small, black, and bearing pale yellowish short bristles ; at first there is no appearance 

 of feet on the 9th segment. As the larva feeds, the middle portion of the body 

 becomes greener, while the head and tail are more yellowish, but after a little growth 

 the green spreads throughout ; when the larva is almost half-grown it plainly shows 

 some rudiments of legs on the 9th segment. When full grown, it is rather over an 

 inch in length, very even in bulk ; the head flattish, but with rounded outline to the 

 lobes ; under the anal flap are two short blunt points ; on segment 9 a pair of feet, 

 perfectly formed, but useless for walking, being about one-sixteenth of the size of the 

 pair on segment 10 : the genei-al appearance of the colouring is yellowish-green, 

 owing to the number of green and yellow lines which run intermixed down the 

 body ; the dorsal line is a pale yellowish thread, ruiming between two dark green 

 lines, darkest at the segmental divisions, and themselves again edged with pale 

 yellowish ; then on a pale jellowish-grcen ground are some pale yellow freckles ; 

 then comes the sub-dorsal line, yellowish, edged "B-ith decided green ; then more 

 yellow freckles ; then a waved, i-ather broken, supra-spiracular line of yellow, edged 

 above thickly but irregularly with green, reaching highest at the beginning and end 

 of each segment, and lowest just in the middle above each spiracle ; the spiraeular 

 region broadly and decidedly green, each black-ringed spiracle with a small yellow 

 halo (and in some individuals behind each spiracle is a conspicuous spot of darker 

 green) ; the sub-spiracular is a stouter undulating line of deeper yellow, edged in 

 parts with dark green ; the belly rather bluish-green ; the head greenish with a tinge 

 of very pale bi'own. 



The cocoon is neatly formed, of long oval shape, and of tough texture, being 

 lined with close woven yellowish silk, and covered with fine earth ; in fact, it looks 

 like a little knob of earth : it is about f inch long, and \ inch broad : the pupa is 

 rather over -j^j inch long, very plump and full, being for the greater part of its length 

 nearly g inch across ; the eye-cases prominent, the abdomen tapering off quickly, but 

 with a blunt end, on which is a flat blaoki.^h knob, furnished with two short widely 

 diverging sliarp spines ; the colour golden-brown, tinged with greenish on the back, 

 the eye-cases, &c., more brown ; the skin finely punctured but glossy. — Id. 



Description of the larva of Scapula lulealis.~For years I have tried to find 

 out the larva of this species, but although the perfect insect is so abundant with us 

 as to become almost a nuisance when it is out, it was not untU the present season 

 that my endeavours were crowned with success. I had done my best to find the 

 larva at lai-ge ; and had watched the $ moths where they abounded, in the hope of 

 seeing them deposit their eggs, from early evenfbg till late at night ; I have had
