Cinereous, sprinkled with fuscous : anterior wings hoary-ash, minutely irroratcd, 

 with three equidistant fuscous spots on the costa, the second of which is pro- 

 duced into a distinct slightly bent striga, and the third into an obsok'te one 

 composed of lunular spots ; behind this last is a broad fuscous band, which 

 also borders the posterior wings, which latter have a dark spot in the centre. 

 The female is smaller, more sprinkled with fuscous, with the strigse more 

 obsolete than in the male. 



Slightly variable in the intensity of the markings and in colour, being sometimes 

 rufescent. 



There appears to be some confusion in the references to this species in the works 

 of the continental writers:— it differs from the typical species by having the 

 male antennaj less plumose, the palpi more scaly, and the maxillije longer. 



Not common within tlie metropolitan district: it lias however 

 occurred in the fir plantation near Birch-wood, and in tolerable 

 plenty between Cobham and Ripley in Surrey ; but near Ririg- 

 weed in the New Forest it has been captured in great profusion in 

 August. 



Genus CLXVI.— M;esia mild. 



Palpi distinct, not concealed in the hairs of the front, shorter than the head, 

 triarticulate, curved, the basal joint rather longer than the two others united, a 

 little stouter and bent, second cylindric, terminal minute, subglobose : maxilla' 

 short. Anicnnw long, moderately bipectinated in the males to the apex, each 

 joint producing a soitiewhat acuminated twig on each side, ciliated within ; in 

 the females obscurely serrated : head short, broad : thorax squamous : wings 

 deflexed during repose, entire whitish, with transverse lines of dots, and a 

 central dark spot. Metamorphoses unknown. 



From Bupalus this genus differs not only by the great dissimi- 

 larity in the structure of the palpi, but in having the antennse less 

 pectinated, the wings whitish and strigated, deflexed during repose, 

 without the basal protuberance on the anterior; and the females 

 are smaller than the males.
