curved, the terminal more slender than the others, obtuse: jnaxiUw rather 

 longer than the head. Anfenvoe blpectinated in the males, serrated in the 

 females, the pectinations incurved, and meeting at the apex : head very small, 

 woolly : thorax stout, very woolly : abdomen slender in the male, robust and 

 slightly acute in the female : ivings subdiaphanous, deflexed, trigonate : legs 

 short, stout ; the anterior tibia; short, with a spine on the inside, the posterior 

 with spurs at the apex. Larva tuberculated, each tubercle producing a tuft 

 of hairs : pupa acute, folliculated. 



The sexes of this genus differ considerably from each "other, but 

 in each the wings are rather abbreviated (especially in the males), 

 and but sparingly covered with scales : the thorax of both sexes, 

 and the femora and posterior tibise of the male, are very woolly, and 

 the palpi have the terminal joint as long as either of the others, and 

 cylindric.

INIale with the antennte black : thorax and abdomen ashy-brown ; the latter 

 with obsolete black spots: wings ftiscous; the anterior with six or eight 

 scattered black spots, the hinder margin immaculate ; posterior with three or 

 four dusky ones towards the hinder margin, and a larger one on the disc. 

 Female very dissimilar : antenna: black : head and thorax snow-white ; ab- 

 domen grayish-white, with five rows of dusky spots, one dorsal, the others 

 lateral; wings white, more or less spotted with black; the posterior generally 

 with some larger spots near the hinder margin ; the hinder margin of the 

 anterior rarely spotted. 



The maculations on the wings vary considerably : I possess one specimen with 

 two minute dots only on the anterior wings, and one on the posterior ; others 

 with about fourteen on the anterior and ten on the posterior wings ; and all 

 intermediate grades, some with the ciha of the anterior wings also spotted. 



Caterpillar cinereous; it feeds on various aquatic plants, in the autumn, and 

 the imago is produced about the middle of May. 



Not very uncommon in several places near London, especially 

 in the marshy places near Dartford, Erith, &c. I once took a fine 

 specimen, which had been impaled by a shrike on a whitethorn 

 bush, in Epping forest. " Norwich." — W. C. Hewitsofi, Esq.
