LEUCANIIN^. 



13 



wings vary from whitish grey to brown, without any reddish or 

 yellowish tinge. At the base is a conspicuous black line, and 

 towards the hinder angle a mark shaped like a \p. On the 

 costa are several rather indistinct black streaks, and between 

 the stigmata is an ;v-shaped black mark. The orbicular stigma 

 is round, with a black edge, but the reniform stigma is very 

 faint. The fringes are greyish brown at the base, and white at 

 the tips. The hind-wings are more or less brownish, with the 

 ners'ures at the tip and the hind margin darker. The larva 

 feeds on beech, lime, poplar, alder, &c. It has a black head 

 with two yellow stripes, and the neck is thickly covered with 

 reddish-browTi and dark grey hairs. On the fifth segment is a 

 very long, black, erect, conical, fleshy, tubercle. The dorsal line 

 is broadly sulphur-yellow and terminates in a tapering eleva- 

 tion, which points backwards, on the twelfth segment. The 

 sides are black, with deep red, slightly curved, vertical streaks, 

 generally two on each segment, approximating above, and 

 there is a small white spot between them on four of the seg- 

 ments. The legs are yellowish-brown and above them runs a 

 whitish longitudinal stripe. The pupa is deep reddish-brown, 

 elongated, and obtuse at the extremity. It is enclosed in a 

 firm silky cocoon, in a cavity in rotten wood. 



SUB-FAMILY III. LEUCANIIN^. 



This is a well-marked group of moths called " Wains- 

 cots " by collectors. The body is generally stout, and the 

 fore-wings rather narrow, of an ochreous or reddish colour, 

 longitudinally but rather indistinctly striated, and often with- 

 out any markings but a few dots. The hind-wings are white 

 or grey. Most of the species are marsh-frequenting insects, 

 and the larvae feed on grass and reeds, sometimes in the 

 stems.
