1576. PlMPRANA ATCINSONI. 



Sub-family CucuLLiANiE. 



Proboscis usually well developed, sometimes aborted or absent ; palpi 

 usually short, upturned or porrect, the 3rd joint sometimes long and dilated 

 at extremity, in Xantholeuca rostriform ; irons sometimes with rounded 

 prominence with corneous plate below it, or with corneous processes of 

 various forms ; eyes naked, overhung by more or less developed bristly cilia 

 from their margins, the eyes usually large and round, sometimes small and 

 reniform ; antennae usually ciliated, sometimes serrate or pectinated, more 

 rarely laminate or almost simple ; head and thorax clothed with hair and 

 scales when there are usually crests on the pro- and meta-thorax or a 

 ridge-like dorsal crest, or clothed with hair only, the tegulse sometimes 

 produced dorsally into a ridge, or in Cucullia and allied genera produced 

 behind into a more or less developed hood over the thorax ; tibiae without 

 spines, the fore tibia sometimes with terminal claws ; the proximal joints 

 of fore tarsi sometimes with a series of curved claw-like spines ; abdomen 

 usually with a series of dorsal crests or one crest at base. Wings usually, 

 rather broad, but often long and narrow, the termen rounded or crenulate, 

 rarely slightly angled at middle ; forewing with vein la weak, not 

 anastomosing with lb, lc absent; 2 from middle of cell; 3 and 5 from 

 near lower angle ; 6 from upper angle ; 9 from 10 anastomosing with 8 to 

 form the areole ; 11 from cell ; hindwing with veins 1 a and b present, lc 

 absent ; 3, 4 from lower angle of cell ; 5 obsolescent from or from just below 

 middle of discocellulars ; 6 - 7 from upper angle or shortly stalked ; 8 arising 

 free, then bent downwards and touching the cell, then again diverging. 

 In Thecophora the male has a very large boat-shaped fovea in disc of hindwing 

 the extremity of subcostal nervure being dilated and played on by the 

 spines of the elongate 1st joint of hind tarsus, the tibia being shortened. 



The imagos mostly appear in the autumn or spring, sometimes 

 hybernating. Larva smooth, the warts with one hair, all the prolegs present, 

 the 12th somite with more or less developed dorsal hump, in Cucullia 

 artemisice there are subdorsal series of double hump-like warts. The larva 

 of Cucullia and allies are usually bright coloured, feeding exposed on plants.
