DESCRIPTIVE NOTICES OF CONSPICUOUS SPECIES 135 



All the wings are transparent, with only the margins 

 clothed with dense opaque scales. The fore-wings have 

 the costa and a broad patch on the inner margin black 

 tinged with green ; the hind-margin is brown, broad 

 towards the apex, narrow at the anal angle ; the trans- 

 parent patch near the base of the wing is not intersected 

 by a longitudinal vein. The hind-wings have the base 

 tinged with yellowish-grey, with the hind-margin brown, 

 and very narrow. The body is greenish, with two black 

 belts, posteriorly more yellowish. 



The larva is green dotted with yellowish-white ; with 

 a subdorsal pinkish stripe, edged beneath with white 

 from the third to the twelfth segment ; the spiracles are 

 reddish-brown, placed in pinkish blotches ; the caudal 

 horn is slightly rough, short, pointed, and reddish. It 

 feeds in July and August, on the devil's-bit scabious 

 (Scabiosa succisa). 



The perfect insects make their appearance in May ; 

 they fly swiftly in the daytime, extracting honey from 

 flowers ; they frequent open places in woods, or meadows 

 by the skirts of woods. From the transparent wings 

 and hairy bodies they have considerable resemblance to 

 humble-bees. 



There is another closely allied species of Bee Hawk- 

 moth, the Broad-bordered Bee Hawk-moth (Sesiafuci- 

 formix) ; it appears in May, and frequents similar loca- 

 lities ; it may be readily distinguished from the Narrow- 

 bordered Bee Hawk- moth, by the greater breadth of 

 the dark margin of the hind-wings, and that of the fore- 

 wings at the anal angle ; the transparent patch at the 

 base of the fore-wings is intersected by a dark longi- 

 tudinal vein. The larva feeds on honeysuckle in 

 July.
