igo LEPIDOPTERA. 



Dover district, but it still remains one of our most local 

 insects. I have never seen it alive. Abroad it is found over 

 the greater part of Central Europe, Northern Italy, Sweden, 

 Livonia, South-east Russia and Bithynia. 



Genus 7. IDIOGRAPHIS. 



Antenna) slender ; palpi rather long, drooping, beak-like; 

 thorax rather rough ; fore wings deeply folded one-third the 

 length of the costa ; nervures thickened ; hind margin of 

 hind wings waved, almost elbowed. 



1. I. inopiana, Ihm-. ; centrana, H. S., Rein.—Ex-ptmse 

 J inch (18 mm.). Fore wings broad, wrinkled, shining 

 drab ; hind wings whitish ; palpi pointing down. 



Antennte dull drab ; palpi long, drooping, though por- 

 rected, brownish drab ; head, thorax, and abdomen of the 

 same colour. Fore wings rather ibroad ; costa broadly folded 

 from the base fully halfway to the middle ; all the principal 

 nervures thickened, leaving hollows between them ; glossy 

 pale drab thickly dusted with brown and without definite 

 markings, but a conspicuous rectangular wrinkle lies before 

 the anal angle; cilia concolorous. Hind wings broad, rather 

 angular behind, smoky white, with white cilia. Female 

 somewhat similar, but the fore wings browner, more even in 

 width, aiid without fold or wrinkle. Hind wings shining, 

 pale smoke colour. 



Underside of the fore wings smoky pale brown ; hind wings 

 white. 



Usually not variable, but the female is occasionally more 

 definitely brown, and in rare instances nearly black. 



On the wing in June and -Tuly. 



L.\UVA apparently undescribed. A short description is 

 given by Baron von Noleken, under this name, of a larva 

 feeding on the rootlets of Artemisia campcstris, but I am 

 pot satisfied that it belongs to this species. Mr. Thurnall
