SPHINGID.E. — SMERINTHUS. 113 



banded with glaucous, with a white lunule, and frequently a broad transverse 

 cinereous fascia in the middle: the posterior wings are less dentated, and are 

 also griseous, with deeper obscure waved streaks, a pale central lunule, and a 

 large rust-coloured patch at the base : the fringe is cinereous, clouded with 

 griseous: the thorax and abdomen pale unspotted cinereous. 



This insect varies much in size and colour ; the male is usually darker than the 

 female, but I have several very pale specimens, with deep cinereous strigas 

 and of the female I have one of immense bulk, and of a deej) cinereous: 

 others of this latter sex are very pale. 



One of my specimens is very remarkable : the right side (antenmr, legs, wings. 

 &c.) being that of the male, and the left that of the female : it was reared from 

 the larva last June, and the individual who presented me with the specimen 

 (Mr. Weaver) also bred a similar one the preceding year. 



The caterpillar also varies much ; it is very rugose, and is usually green, with a 

 yellowish line on each side of the anterior segments, and an obhque transverse 

 stripe of a similar colour on the rest, the last terminating on the tail ; the stig- 

 mata are rosy; and frequently each segment bears a large red spot, and the 

 lateral hues are of a more brilliant cast : it feeds chieHy upon the poplar, but 

 also eats willows and aspen ; is full grown towards the end of September, and 

 changes beneath the earth to a dull brown pupa. 



The perfect insect appears towards the end of June, and is vcrv 

 common in the south of England ; a larva which was brought to mo 

 in July last, at Ripley, underwent all its changes, and arrived at 

 maturity at the beginning of September. " In plenty in Devon- 

 shire." — Dr. Leach. " Near Carlisle." — T. C. Hajsham, Esq. " In 

 Northumberland.""' — W. C. Hexvitscm, Esq. " Very abundant in the 

 neighbourhood of Ely." — Rev. L. Jenyns.
