14 HAUSTELLATA. — LEPIDOPTERA. 



towards the anal angle are two black spots, the inner one largest : posterior 



wings dusky-ash : thorax with a fuscous patch anteriorly. 

 Caterpillar brown, with a flesli-coloured, spotted, dorsal line, the protuberances 



and spots on the sides rufescent : it feeds on willows and poplars : pupa brown. 



The only specimens I have seen of this fine insect are in the 

 collection at the British Musenm; I am not aware of their locality : 

 Dr. Leach obtained them from the collection of Mr. Spratt.

 Ph. Bo. curtula. Linne. — Ch. curtula. Steph. Catal. No. 5956. 



Griseous: somewhat allied to the last: anterior wings glaucous or greyish-ash, 

 with four nearly straight whitish striga?, the outer, or fourth, a httle flexuous 

 towards the costa, where it terminates in a white spot : beyond this the apex 

 is of a bright testaceous-brown, with an obsolete row of dusky spots : posterior 

 wings greyish-ash : thorax anteriorly, and on the back rufous-brown, the 

 sides cinereous, or faintly tinged with reddish : abdomen with its tuft red- 

 dish-brown at the apex. 



Caterpillar cinereous, with four rows of ferruginous spots : it is found in Sep- 

 tember, feeding upon poplars and willows. 



Taken occasionally near London towards the end of April, or 

 beginning of May, but far from common. " Wanstead, on the

Genus XXXVL — Episema, Ochscnliehner. 



Palpi elongate, very pilose, biarticulate, the basal joint large, the terminal very 

 slender elongate, acute, scaly: muxiUw short. Antenna; rather elongate, not 

 curved, bipectinated to the apex in the males, simple in the females: head 

 exserted; not very small: thorax slightly crested with transverse fascite : abdo- 

 men rather stout, with a simple tuft at the apex : wings elongate, anterior entire 

 on the hinder margin ; cilia long : legs very hairy ; tibicr with spurs. Larva 

 cyhndric, very fleshy and robust, not tuberculate ; the hinder legs perfect : pupa 

 folliculated. 



In the texture of its wings, and in the comparative robustness 

 and magnitude of its larva, this genus unquestionably resembles the 

 following, although the structure of the latter and that of the imago 

 offer several points of distinction : the location of the genus has 

 been frequently changed ; but the short filamentous tongue appears 

 to point out the present family as its true situation.
