58 HAUSTELLATA. LEPIDOPtERA. 



but in great plenty on the oaks, near Brockenliurst, in the New 

 Forest. " Epping." — Mr. H. Doicbleday. 



Genus LXI. — Dasychira, Hubner? 



Palpi very short, hairy, triarticulate ; the basal joint about one-third the length 

 of the second, and more slender, the terminal ovate, acute : maxillw obsolete. 

 Antennw short, acute at the apex, thickly bipectinated, especially in the male ; 

 the pectinations deeply ciliated, and shortest in the females: head small, 

 hairy : thorax rather stout, not crested : abdomen somewhat robust, especially 

 in the females, woolly beneath : wings deflexed, elongate, thickly and densely 

 covered with scales : legs short, stout, pilose ; femora and tihia and anterior 

 tarsi fringed with long hairs. Larva very hairy, with several compact trun- 

 cated tufts on the back, and another on the tail : pupa hairy, enclosed in an 

 ovate folliculus, its posterior extremity with an acute projection. 



Dasychira differs more in its preparatory states, than in the 

 imago, from the two foregoing genera ; but the dissimilarity in its 

 palpi and elongated wings, with its stout, fringed, and prominent 

 anterior legs, well distinguish it from them : from Demas it may be 

 known by its thorax not being crested, and from Orgyia by the 

 acuteness of the apex of the antennae and triarticulate palpi. The 

 species of this genus considerably resemble those of Cnethocampa. 



Sp. 1. fascelina. Alis cinereis, anticis nigro-irroratis, strigis duahus fulvo-fuscis

Ph. Bo. fascehna. Linne.—Don. xvi. pi. 576. — Da. fascelina. Stcph. Cafal. 

 No. 6006. 



Antenna; and thorax hoary, fuscous: anterior wings grayish-brown, with a 

 griseous tinge, minutely irrorated tlu-oughout with black, with an obscure 

 striga at the base, another before the middle, and a third much undulated 

 behind the middle of a fuscous-brown, and between the latter and the hinder 

 margin some obsolete fuscous or black transverse spots; and an undulated 

 pale ash-coloured line : posterior wings dusky, with an obscure darker mar- 

 ginal fascia. Female larger and paler : the apex of the abdomen black. The 

 posterior wings are sometimes immaculate in both sexes; and the colours of 

 the markings on the anterior vary considerably, the strigae being occasionally 

 nearly black instead of fulvous : the hinder margin of the anterior wings has 

 sometimes a row of interrupted black dots. 



Caterpillar dusky, spotted with yellowish, with five dorsal fascicles of white hairs 

 tipped with black, two fusiform brown ones on the head, and one at the tail : 

 it feeds on various plants, especially the trefoil, dandelion, hop, bramble, oak, 

 &c. in the autumn; and breeds through the winter, changing to a hairy brown 

 pupa, with a pale dorsal hue in May : the imago appears in July. 



Rather an uncommon species, occurring most frequently in the
