ENDROMIDIDAE 319 



Ovum rounded -oblong, smooth. Larva stout, attenuated 

 anteriorly, with few hairs, all prolegs developed. Pupa in a 

 tough elongate-oval cocoon above ground. 



1. ENDROMIS, 0. 



Characters those of family. 



1. E. versicolora, L. 50-85 mm. Fore wings ochreous-brown, 

 median band in $ much suffused with white ; lines blackish, ex- 

 ternally whitish-edged, first somewhat curved inwards, second 

 rectangularly broken below middle ; an angulated blackish 

 discal mark ; a partial white subterminal line, forming three 

 connected spots towards apex ; veins terminally white. Hind- 

 wings in <$ orange, in $? whitish ; markings as in forewings but 

 less developed, first line absent. 



Britain to Caledonian Canal, local ; N. and C. Europe ; 4. 

 Larva pale green; dorsal line darker green; on 5-11 a lateral 

 series of oblique whitish or yellowish dark-edged stripes ; spira- 

 cular area beneath these deep green, irrorated with black ; 

 spiracles white; a pointed prominence on 12, with whitish 

 lateral stripes : on birch ; 6, 7. 



3. LASIOCAMPIDAE. 



Head densely rough-haired. Ocelli absent. Eyes partly or 

 wholly hairy. Tongue obsolete. Antennae in <$ bipectinated 

 to apex. Labial palpi porrected, densely rough-haired. Thorax 

 densely hairy above and beneath. Abdomen hairy. Femora 

 and tibiae densely hairy, posterior tibiae without middle-spurs, 

 end-spurs short. Forewings : Ib simple, 8 to termen. Hind- 

 wings without frenulum, 4 and 5 approximated or stalked, 8 

 anastomosing or connected with 7 or upper margin of cell. 



Fairly numerous in species, and generally distributed except 

 in New Zealand, but more commonly within the tropics. Imago 

 with stout body and rather elongate -triangular forewings; 

 usually of moderate or large size, and generally nocturnal in 

 habit. A near relationship to the Psychina is indicated Vty the 

 pseudoneuria or false veins which are often developed (in exotic 

 forms sometimes much more numerously) as branches from vein 

 8 of the hindwings to the costa ; these are very subject to 

 variation, and are also frequently ill-defined or irregular or 

 partially obsolete. 



Ovum oval, smooth. Larva stout, more or less densely
