1 50 LEPID OP TERA . 



brown, shiuing ; dorsal plate diaphanous, siiiniug hazel 

 colour, divided by a pale dorsal line, on either side of which, 

 near the base, is a darker undefined patch ; anal segment, 

 suddenly attenuated, bears a hazel-brown cloud. (Wilkinson.) 

 September till April or May in the root-stock of common 

 mugwort (Artcinisia tmlgaris), eating the pith of the thick 

 stem and the rough root-stock, especially in the strong side 

 shoots ; spinning up in the same place. 



Pupa rather compressed and of even thickness ; head, 

 thorax, and wing-case smooth, shining black; abdominal 

 portion pale hazel on the ventral, and deep red-brown on 

 the dorsal surface ; cremaster armed with coarse, deep 

 chestnut-coloured booklets, (Wilkinson.) 



This is a very vigorous and active species ; it flies in a 

 wild manner and rather high about tall plants of mugwort 

 growing in hedges or waste ground in the late afternoon sim- 

 shine and till dusk; also it sits from time to time upon 

 the plants, and in dull weather may often be disturbed 

 by the beating stick. It also certainly tlies at night, since 

 it is strongly attracted by a light at that time. Rather a 

 local species, and usually not very common. Still to be 

 found occasionally in the southern suburbs of London and 

 elsewhere in Kent and Surrey, also in Hants, Devon, 

 Somerset, Herts, the Eastern counties, including Cambs. ; 

 also in Oxfordshire, Gloucestershire, Worcestershire, and 

 rarely in Durham and Cumberland, But, so far as I can 

 ascertain, this is the extent of its range in these Islands. 

 Abroad it is widely distributed through Central Europe, the 

 north of Italy, Scandinavia, Finland, Greece, Armenia, and 

 Turcomania. 



8. H. trigeminana ; Steph. — Expanse h to f inch 

 (12-16 mm.). Fore wings mottled, red-brown with olive-
