DESCRIPTIVE NOTICES OF CONSPICUOUS SPECIES 251 



beyond the middle ; it is followed by a small whitish 

 blotch, and a few short longitudinal silvery-leaden streaks ; 

 the female has the fore-wings much paler, sometimes 

 almost whitish, but the markings are precisely similar. 



The perfect insect appears about the middle of May, 

 nearly at the same time as the Common Swift (Hepialus 

 lupulinus) (see ante, p. 140), and continues out through 

 the month of June and a great part of July ; it flies in 

 profusion in every hayfield and grassy meadow ; it comes 

 very freely to light. 



FAMILY XVI. CBAMBID^E. 

 C RAMBUS HAMELLVS. 



(Plate XIII., Fig. 6.) 



This brightly marked species occurs not uncommonly 

 on the sandy district about Weybridge, and also in the 

 New Forest; northwards it has been met with near 

 Manchester ; and in Ireland, it has occurred near 

 Killarney. 



The expansion of the wings is nearly an inch. The 

 fore-wings are glossy brown, with a broad, conspicuous, 

 silvery- white streak from the base to considerably beyond 

 the middle ; when it tapers from each side to a point ; 

 on its lower side, nearly in the middle of the wing, is a 

 small tooth-like projection ; and beyond the end of this 

 streak is an angulated, transverse, dark line, and the 

 other markings as in the preceding species. 



The perfect insect appears in July, and may be readily 

 started as we walk along the heather in the localities 

 which this species frequents ; like most of its congeners, 

 where found it will be in tolerable plenty.
