138 HAUSTELLATA. LF.PIDOPTEI5 A. 



frequently witli an elongate orange streak ; cilia flavescent, clouded with 

 black. Female with the markings more distinct. 



An extremely variable species^ but the male sufficiently known from its con- 

 geners by the want of pectinations to its antennse, and the female by the 

 brilliancy of the orange on the posterior wings, the broader and more inter- 

 rupted black fimbria thereon, and the distinctly jointed antennae. 



Caterpillar green, with the head brighter, with a yellowish dorsal, and broader 

 griseous lateral lines : it feeds on the birch, oak, and hazel : — the imago 

 appears at the end of March. 



Found near Coombe and Bircli woods, especially in tlie latter 

 neiglibourhood, but not very abundantly. I have reared it from a 

 larva taken at Darenth-wood . It also occurs in other parts of the 

 metropolitan district. " Rather plentiful, flying during the day in 

 fir plantations, on 22d March, near York."^ — W. C. Hewitson, Esq. 

 " On gar-par k-woods, common." — J/r. Doiihleday. 



Genus CLXI. — Euclidia, Ochsenheimer. 



Palpi rather short, porrected obliquely, the basal joints clothed with elongate 

 hairs, the apical exposed and somewhat linear; basal joint about of equal 

 length with the terminal, rather stouter than the second, which is more 

 than as long again as the basal, a little curved, somewhat tumid anteriorly and 

 attenuated to the apex, terminal elongate-linear, slender: maxillos rather long. 

 Antenna} short, simple in both sexes, slightly pubescent in the males : head 

 small : eyes naked : thorax subglobose, not crested : abdomen slender, rather 

 elongated, ovate and more robust in the females, the segments usually with 

 pale edges: wings deflexed, anterior entire, generally marked with trans- 

 verse bars and figures, resembling mathematical symbols : posterior yellowish, 

 with blackish spots or bars: legs slender. Larva slender, naked, with six- 

 teen legs, the first pair of prolegs rather short; pupa foUiculated, not sub- 

 terraneous. 



The genus Euclidia may be known by the shortness and width 

 of the anterior wings, which are usually marked with distinct irre- 

 gular fascise or lines resembling geometrical figures ; the posterior 

 wings are also distinctly marked, and are usually of a yellowish 

 hue, more or less fasciated with black or dusky: the abdomen 

 is rather elongate and distinctly annulated : — the species fly by day, 

 especially between the hours of two and four in the afternoon.
