NOCTUID^. COSMIA. 59 



The ascending squamose palpi of tLis genus readily distinguish 

 it from Bombycia, with which the males agree in having the an- 

 tennae bipectinated; and the breadth of the anterior wings, as well 

 as the robustness of the thorax, the densely woolly under surface, 

 and the pubescent abdomen of the male, and elongated acute one 

 of the female, form the prominent marks of distinction. By this 

 last character the females approach towards those of the following 

 genus, but the rotundity of the hinder margin of the anterior wings 

 and subserrated antennse at once divide them therefrom.

 JVo. 6311. 



Head and thorax pale ochraceous-yellow, sprinl-ded with dusky; anterior wings 

 pale yellow, with a pale ferruginous fascia near the base, and another between 

 the stigmata, but united to the anterior margin of the posterior one ; before 

 the middle is a submoniliform incurved striga pointing towards the body; 

 and behind is a second arcuated one, both formed by a pale ferruginous ge- 

 minated striga ; and towards the hinder margin is another ferruginous striga, 

 a little ciu-ved near the costa; the liinder margin is pale ochraceous yellow; 

 the nervures tliroughout are ferruginous, and produce a reticvdated appearance; 

 the stigmata are very conspicuous, pale-yellow, with ferruginous edges, the 

 anterior one round, the posterior heart-shaped, with a more or less distinct 

 angulated ferruginous central mark; between the anterior stigma and the 

 inner margin is a third round or ovate stigma, also yellow, edged with fer- 

 ruginous; cilia spotted with the latter colour: posterior wings yellowish- white. 



Var. 0. With the base of the anterior wings clouded with dusky-ferruginous^ 

 and a broad fascia of the same colour extending from the posterior stigma 

 nearly to the hinder margin ; in other respects similar to the above. 



Caterpillar ferruginous or dusky, with white spots and lines, and the head 

 black : — it feeds on the oak, and the imago is produced towards the beginning 

 of June or the end of May. 



Not very common ; it has however been taken rather plentifully 

 near Chigwell-row, in Epping Forest, and at Darenth-wood. I 

 have also taken it on Clandon Common, and it has been found in 

 other places in the vicinity. " Leatherhead." — T. Luptoriy Esq.
