NATUEAL HISTOEY OF £OARMIA CINCTARIA. 

 BT WILLIAM BUCKLER. 



It gives me pleasure to record my tbanks to Mr. J. Gr. Ross for 

 kindly supplying me witb eggs of tbis species on May 2Gtb, 1876, 

 wbicb were laid togetber in a cluster. 



In sbape, tbe egg is elongate, elliptical, bluntly rounded at one 

 end, and more gradually at tbe otber, near wbicb occurs a depression ; 

 tbe surface ribbed longitudinally and pitted ; in colour ligbt olive- 

 drab, iridescent witb tbe play of ligbt in tbe numerous pits, and 

 baving a sligbt degree of transparency sbowing wben beld against tbe 

 ligbt, tbe darker embryo witbiu ; tbe colouring cbanges tbe day before 

 batcbing to pinkisb-grey. 



Tbe larvae batcbed May 28th, and at first tbey were dark olive- 

 brown, witb pale olive-green bead, a wbitisb stripe along tbe back, 

 auotber along tbe side ; several kinds of food were given tbem, but 

 tbey unmistakeably preferred bircb, on wbicb, after wandering over 

 otber leaves, most of tbem settled down, and began to eat minute 

 patcbes of cuticle from tbe under-side, causing transparent specks to 

 appear on tbe upper surface of tbe leaves. By 3rd of June, some bad 

 escaped, probably during my previous inspection, and one bad died on 

 an oak-leaf, tbe remaining twelve bad moulted, and were pale greenisb- 

 yellow on tbe back, witb a very broad darker greenisb stripe on each 

 side. After auotber moult, by tbe Otb, tbey were a quarter of an inch 

 long, of olive-green colour, witb several fine, equidistant, double, longi- 

 tudinal, darker lines ; at tbis time tbey were very lively active loopers, 

 and bad been apparently feeding a little on oak as well as birch, but 

 preferring the latter. By tbe 12tb, tbey were five-sixteenths of an inch 

 long, and much paler green in colour, with lines only just visible, and 

 by tbe 15th, bad again moulted and become darker, and on tbe 18th, 

 were nine-sixteenths of an inch long, having distinct dark lines with 

 the addition of pale sub-dorsal stripes ; by the 23rd, the most forward
