 Laria, Schrank. DASVCHiRiE, Hiibn. 



Legs, anterior hairy, stretched out forwards, when at rest*. 



Antennce, — in the male strongly bipectinate ; in the female only 

 slightly feathered. 



Haustellum very short. 



TVmgs deflexed. 



Larva, with hairy tufts on the head, back and posterior por- 

 tions of the body. 



Pitpa hairy ; the metamorphosis takes place in a double web 

 mixed with hairs f.

* Hence the name of the genus, from o^sya, extendo, and yviov, membrwm, 

 \ Stephens has adopted Ochsenheimer's genus Orgj/ia, for his two last 

 species, Gonostigma, and Antiqua, with the following characters : 

 " Palpi short, compact, hairy, biarticulate ; the basal joint small, the ter- 

 minal large, broad, ovate, subacute: maxilltB obsolete. AntenndB short, 

 deeply bipectinated in the males, abruptly terminated : serrated in the 

 females, each serrature producing a bristle : head small, hairy : thorax 

 slender, not crested : tv'mgs deflexed, short, triangular, or wanting : 

 legs rather stout, anterior elongated ; the femora and tibicB of all, and 

 the tarsi of the anterior, fringed with elongate hairs. Larva with 

 distinct fascicles of hair on the sides, and several dorsal tufts ; two or 

 more, composed of capitate hairs, on the sides of the body and head ; 

 one on the penultimate joint, and some shorter ones at the apex : 

 pupa slightly pilose, with an acute spine at the tip: folliculus ovate, 

 of a very loose texture." — Illust. Brit. Ent. Haust. II. 60. 

 The females of this genus are apterous.

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

 length of the second, and more slender, the terminal ovate, acute : 

 maxilla obsolete. Antennce short, acute at the apex, thickly bipec- 

 tinated, 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 : ivings deflexed, elongate, thickly and densely covered with 

 scales: /eg* short, stout, pWose ; jfeynora and tibice, and exterior tarsi 

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

 cated tufts on the back, and another on the tail : pupa hairy, en- 

 closed in an ovate folliculus, its posterior extremity with an acute pro- 

 jection."— ^^c/jA. Illust. Brit. Ent. Haust. II. 58. 

 Dasi/chira, Stephens adds, differs " from Orgi/ia, by the acuteness of the 

 apex of the antennae, and triarticulate palpi. The species of this genus 

 considerably resemble those o(C7iethocampa."—iGast?-opacha, Ochs,)Stepk.
