8 LEPIDOPTERA. 



that one is led to suspect a confusion with the larva of one 

 of the larger Bombyces. 



Pupa very stout and round ; wing-cases short ; tail rounded, 

 with a small projection having minute hooked bristles. Red- 

 brown or dull red ; wing-covers and incisions of the segments 

 darker; spiracles black and prominent. In a hard, compact, 

 grey, oval cocoon, which is lined inside with white silk ; 

 among rubbish on the ground. (C. Fenn.) The cocoon is 

 covered externally with earth. 



The moth flies actively early in the evening and again late 

 at night, but is not often observed in the imago state. The 

 male may sometimes be attracted by a strong light. It is 

 mainly confined to woods and wooded districts, though not 

 wholly so. Fairly common in Kent, Surrey, Sussex and 

 Berkshire, and generally distributed over the southern half 

 of England to Norfolk and Herefordshire, though scarce in 

 the Midland counties and rare in Staffordshire ; rare also in 

 Lincolnshire, Yorkshire, Cheshire and Lancashire. In Scot- 

 land, rather widely distributed in the southern districts to 

 Ayrshire ; also in Aberdeenshire, Inverness-shire and Argyle- 

 shire. In Ireland it is only recorded from Killarney. Abroad, 

 generally distributed in Central and Northern Europe, except 

 the extreme north ; in Spain, Northern Italy, Turkey and 

 Armenia. 



Genus 3. ERIOGASTER. 



Antennae rather short; stifily pectinated in the male, 

 shortly so in the female ; thorax stout ; abdomen in the male 

 not stout, but with a considerable anal tuft : in the female 

 cylindrical, very thick, and with a large dense mass of scales 

 forming the anal tuft ; fore wings rather long ; hind wings 

 short ; both rather thinly clothed with scales. 



Like the preceding, a genus well represented and widely 

 distributed in the world, though we have but one native 

 species.
