202 HAUSTELLATA. — LEPIDOPTERA. 



short, curved ; the second rather longer, compressed ; terminal elongate-sub- 

 clavate: maxiUw rather long. Antennw rather long, incurved, in the males 

 bipectinated nearly to the apex, each of the pectinated joints producing on each 

 side rather a long ciliated twig ; in the female simple : head small, prominent 

 anteriorly: eyes globose: thorax slender, slightly velvety: wings partially 

 expanded during repose, entire ; anterior with the superior angle very acute, 

 the hinder margin obscurely repanded; posterior with the middle of the 

 hinder margin produced to a point : all traversed by a striga which passes 

 diagonally from apex to apex of the anterior ones: abdomen slender, stouter 

 and rather obtuse in the females. Larva not tuberculated, thickened an- 

 teriorly : pupa attenuated, formed in a slight web amongst leaves. 



This genus is well known by the very acute anterior angle of 

 the anterior wings, and the angulated or rather subeaudated hinder 

 margin of the posterior ones, combined with the oblique striga 

 which passes through their disc from the apex of the one anterior 

 wing to that of the other, the very short palpi, strongly pectinated 

 incurved antennae of the males, and pale flavescent hue : it is evi- 

 dently closely allied to some of the species of the preceding genus, 

 but what affinity it can possibly have to Hipparchus, near which it 

 has been recently placed, I am at a loss to comprehend.

Pale ashy-yellow, sprinkled with griseous, with a very oblique common purplish- 

 red or sanguineous striga arising at the apex of the anterior wings, and passing 

 through the middle of the inner margin, and a little before the middle of the 

 posterior ; towards the base of the anterior wings is a very obscure pale fuces- 

 cent striga, a fuscous dot on the disc, and an obsolete repanded common fuscous 

 striga towards the hinder margin, intersecting the purple one at the apex of 

 the anterior wings : on the hinder margin of all the wings is a bright slender 

 purple line, and the cilia are also purple, but of a paler hue, and sometimes 

 flavescent at the tips. 



In fine examples, the hinder margin of all the wings is beautifully suffused with 

 rich sanguineous purple. 



Caterpillar reddish-brown, with darker shades, and a paler dorsal line : it feeds 

 on the hazel, whitethorn, &c., and the imago appears at the end of June, 

 and flies very heavily. 



Very local, but in some places extremely abundant, especially in 

 the lanes near Ripley ; it also occurs near Hertford, in Copenhagen-
