76 LEPIDOPTERA. 



Genus 2. PLATYPTERYX. 



Antenna in both sexes pectinated to the tip ; fore wings 

 hooked and with the hind margin toothed and scalloped ; 

 hind wings broad. 



We have but one species. 



1. P. lacertinaria, L. ; lacertula, Schiff. — Expanse 

 1^ to H inch. Fore wings light brown, with two darker 

 brown lines, tip hooked, hind margin toothed ; hind wings 

 whitish. 



Antennae of the male rather shortly pectinated throughout ; 

 pale brown ; head light brown ; thorax narrow, smooth, pale 

 brown ; abdomen short, rather slender, greyish-white. Fore 

 wings arched at the base, thence rounded with a long curve 

 which becomes more decided toward the apex, the latter 

 being bent down into a produced and blunt hook ; hind 

 margin hollowed below the apex, and then rounded, but 

 having scalloped hollows and rounded projections throughout, 

 except at the anal angle ; dorsal margin gently rounded. 

 Colour pale brown, with the nervures rather darker and the 

 whole surface reticulated with very delicate transverse brown 

 lines ; first and second transverse lines nearly straight, but a 

 little bent back to the costa, oblique and nearly parallel ; 

 the space beyond the second tinged with darker brown, 

 darkest toward the margins ; between the two lines at the 

 apex of the discal cell is a black dot ; costal margin toward 

 the tip, and also the hind margin, especially round the pro- 

 jections, edged with dark brown, and the latter having 

 blackish cilia, while those of the hollows are white. Hind 

 wings rather long, hind margin undulating, almost scalloped ; 

 apex rather angulated ; anal angle squared ; white, tinged 

 with brown, especially toward the hind margin, which is edged 

 with a dark brown line ; cilia mixed, brown and white. 

 Female with the antenna very shortly pectinated throughout, 

 rather larger and stouter, otherwise similar.
