BOMBYCID/'E. — ODONESTIS. 51 



scure cinerescent fascia, followed by a somewhat ferruginous band, lobated 

 posteriorly, and irregularly margined on each side with fuscous and pale 

 griseous; the hinder margin is of an ashy-griseous: the posterior wings are 

 deep immaculate griseous : the female larger and paler. 

 Caterpillar variegated with white, gray, and brown, with the anterior segments 

 adorned with two blue transverse dorsal streaks, and some red spots on the 

 sides : it feeds on various species of pine, forms an elongate yellowish-gray 

 web, and changes to a brown pupa, with the abdomen reddish. 



Unquestionably a rare insect in Britain; so far as my information 

 extends, one specimen only has been captured within the last thirty 

 years ; that was taken by Mr. Sparshall, in the Norwich Hospital, 

 in July, 1809 ; and a reputed British specimen is in the collection 

 of Mr, Vigors. Wilkes, who first notices it as a British insect, tells 

 us that he once found the larva in a white thorn, near Richmond 

 Park, but he did not succeed in rearing it to perfection. 



Genus LVII. — Odonestis, Gtrmar. 



Palpi elongate, porrected, hairy, triarticulate, the basal joint not half as long as 

 the second, the terminal rather larger tlian the basal, obtuse : maxilla' obsolete. 

 Antennce slightly curved near the base, bipectinated, especially in the males, 

 to the apex: head small: ihorax stout, loosely but thickly pilose; ahdomen 

 the same, elongated, and tufted at the apex in the males, somewhat acute and 

 stout in the females: w'/igs reversed when at rest; anterior rather acute at 

 the tip, the posterior margin rounded, entire ; posterior slightly denticulate : 

 legs stout, densely pilose, especially in the males, with spurs at the apex of 

 the tibise. Larva robust, cylinth-ic, with fascicles of hair down the sides, a 

 distinct tuft on the neck, and another placed on a minute tubercle on the 

 penultimate joint : when alarmed, it roUs itself in a ring : 2Mpa robust, obtuse, 

 placed in a fusiform, closely-woven, luteous cocoon. 



Odonestis has the palpi more hairy and prominent than Eutricha, 

 and the second joint above twice the length of the first; the an- 

 tennai are more curved towards the base, and more deeply pec- 

 tinated ; the anterior wings acute at the apex ; the thorax and ab- 

 domen less compactly pilose, and the legs shorter, stouter, and 

 densely clothed (the femora and tibia? especially) with elongate 

 hairs.
