Pale luteous-yellow : anterior wings with a straight striga before the middle, 

 and a slightly repanded oblique one" behind, the space between rather darker, 

 and between these strigae is a fuscous or black dot : posterior wings paler im- 

 maculate. 



Variable: in some instances the hinder margin of all the wings has a row of 

 fuscous dots, and the fascia on the anterior is occasionally fuscescent, with 

 the strigse nearly black ; these latter always approximate towards each other 

 on the inner margin: — the posterior wings have sometimes a dark central 

 spot, and a faint transverse striga behind the middle. 



Caterpillar robust, dull brown, slightly pilose : it feeds on various trees and 

 herbs— on the oak, elm, apple, honeysuckle, &c. : the imago appears in June. 



Not uncommon in the woods round London, and in other parts.

Genus CLXXIV. — Odontopera * mihi. 



Palpi distinct, porrected obliquely upwards, densely pilose at the base, the apex 

 squamous and exposed, triarticulate, the basal joint a little bent, and robust, 

 the second rather longer, attenuated to the apex, the terminal minute, placed 

 obliquely : maxilla; elongate. Antennce long, of the males each joint produces 

 a short, clavate twig on each side, the twigs gradually shortening to the apex ; 

 of the females slightly serrated within : head rounded : thorax stout, velvety : 

 abdomen rather stout, with a tuft at the apex, more robust and obtuse, with 

 the apex ciliated, in the females: wings slightly deflexed ; the hinder margin 

 of the anterior deeply and irregularly, and of the posterior slightly and regu- 

 larly, dentate; all with a central ocellar spot. Larva with 10 legs, elongate, 

 cylindric, with a few scarcely elevated tubercles 5 head slightly emarginate 

 above : pupa changes in a delicate cocoon in moss or under leaves. 



Odontopera differs from the foregoing genus not only by having 

 the maxillae distinct and elongate, but in the form of its wings, 

 which are more slender in proportion to the bulk of the body, and 

 very deeply notched; from Geometra it differs in having the an- 



ohv, dens ; Ilsaa;, terminus.
