I04i HAUSTELLATA. — LEPIDOPTERA. 



on the dorsal and abdominal crests : anterior wings marbled with rufous and 

 cinereous^ with an elongate flexuous silvery character, extending nearly from 

 the base of the inner margin to about the middle of the wing, where it becomes 

 somewhat expanded ; on the costa, towards the apex, is a somewhat triangular 

 pale streak : posterior wings as in PI. Gamma. 



f Var. (o ? With tlie flexuous silvery stripe extending from the second striga to 

 the anterior edge of the third, and throwing off a branch towards the costa. 



The form of the silvery mark is very dissimilar in this variety to the former; 

 its origin commencing about the centre of the second striga, instead of the 

 junction of the same with the base of the inner margin ; its form is also dif- 

 ferent, being rather arcuated than flexuous. 



An insect of great variety, of wliicli tlie examples in the late 

 Mr, Swainson's collection are tlie only specimens I have seen ; but 

 of tlieir locality I am not aware. There is a specimen in Mr. Do- 

 novan's cabinet, which is said, by Mr. Haworth (vide Entomological 

 Transactions, v. i. p. 241.) to have been taken in Essex; but Mr. 

 Donovan tells us that it was found in Yorkshire, seemingly from 

 having confounded it with the preceding species. " Near Hull, 

 Yorkshire.'' — W. C. Hezeitson, Esq.

Fuscous, tinged with purplish : anterior wings of a rich purplish-brovra, with 

 darker undulated strigse, nearly as in PI. Gamma; at the base are several 

 flexuous golden striga, and towards the costa, near the apex, is a mark of 

 a similar hue, resembling a reversed 3 : in the centre of the wing is a large 

 briUiant silvery patch, producing two lobes towards the costa ; the rest of 

 the wing and the posterior wings resemble those of PI. Gamma. 



One specimen only of this species has hitherto come under my 

 inspection; it is in the cabinet of W. Swainson, Esq., formerly be- 

 longing to his father; but of its locality the possessor could not 

 furnish me with any particulars. It appears to be as unknown to 

 the continental writers.

Head orange or fulvous, varied with griseous; thorax gray, with an orange 

 fascia ; anterior wings pale fuscous, with three transverse strigfp, and a large 

 subtriangular golden-green patch in the middle, broadest anteriorly, and nar- 

 rowed towards the inner margin ; in the hinder margin is a fine yellowish 

 line ; tlie cilia are fulvous, with dusky spots : the posterior wings brownish, 

 with the base palest, and the margin darkest ; cilia dirty- white.
