GlEOMETRIDiE. HAUPALYCE. 221 



sexes, but ciliated within in the males: head small: eyes large, globose: 

 thorax slender, slightly lobate : luings short, triangular during repose; 

 anterior trigonate, with a more or less solid band in the middle, and an 

 obscure one at the base, the outer margin more or less angulated ; towards 

 the apex of the hinder margin generally a didymated spot, or the rudiments 

 of one; the hinder margin itself entire: posterior rounded, not very ample: 

 abdomen short, very slender, with a large tuft at the apex, in the males, 

 stouter and very obtuse in the females. Larva slender, naked, not tubercu- 

 lated, generally with paler lateral lines : pupa folliculated. 



The beautiful insects comprised in this genus, which is chiefly 

 composed of the Cidarise of Treitschke, may be known by the 

 brevity of the anterior Mangs, which have their hinder margins 

 entire, and bear a broad somewhat dolabriform central iliscia, in 

 which are generally darker undulated strigse and a black dot, as in 

 the preceding genus, from which, however, it differs by having the 

 male antennae not pectinated, but simple, with a slight pubescence 

 within: they have also, like the true Cidariaj, a didymated spot 

 towards the apex of the hinder margin of the anterior wings.

Anterior wings fulvous-yellow, with a slender fulvous-brown fascia at the base, 

 and a broad one in the midclle,vthe latter a little sinuated within, and strongly 

 unangulated without ; attenuated towards the inner margin, and frequently 

 pale fulvous on the costa : towards the apex of the wings is a conical yellow 

 spot ; terminating behind in an oblique pale fuscous streak, near which is a 

 fulvescent cloud : posterior wings whitish-yellow, immaculate : cilia of all 

 luteous, the anterior with fuscous spots. 



The fascia varies slightly, and the base of the wing is sometimes brown. 



Caterpillar greenish, whitish yellow above, with a broad whitish dorsal line : 

 it feeds on the rose :— the imago appears about the end of June. 



Not very abundant, but nevertheless somewhat common in thick 

 shrubby lanes and on the borders of woods within the metropolitan 

 district. " Rockcliff, Black-hall, &c." — T. C. HeijsJiam, Esq.
