2 So LEPIDOPTERA. 



Suffolk, Norfolk (many places), Cambridgeshire, Oxfordshire, 

 Somerset, and Gloucestershire, and rather commonly in East 

 Devon. This is the extent, I think, of its ordinary range, 

 but one specimen seems to have been taken at Chartley Moss, 

 Derbyshire ; and two localities are on record in Yorkshire. 

 Apparently absent from Wales, Scotland, and Ireland. Abroad 

 it is found in most parts of Central Europe, in Southern 

 Sweden, Northern Italy, and Livonia, but does not seem to 

 extend beyond Europe. In Asia and America three or four 

 curious closely allied species are known, but as a group these 

 seem to stand quite alone. 



Genus 2. BOLETOBIA. 



Antennas of the male pectinated and very faintly ciliated ; 

 palpi long, straight and slender ; eyes rough, but naked and 

 without lashes ; head tufted in a blunt knob ; thorax narrow, 

 much crested at the back ; abdomen slender, smooth ; fore 

 wings rather ovate, with rounded costa and hind margin ; 

 dorsal margin of the hind wings furnished with long curved 

 hair-scales which bend over the body. 



We have only one species. 



1. B. fuliginaria, L. — 'Expanse § inch. Palpi long, 

 straight, very slender ; fore and hind wings rounded as in a 

 Geomctra, black-brown or smoky-black, each with three lines 

 of short yellowish streaks and angles ; costa of fore wings 

 dotted with the same. 



Antennas of the male pectinated with solid, minutely 

 ciliated teeth to three-fourths of their length, whence they 

 taper off, the remainder being threadlike, black-brown ; palpi 

 rather long, straight, very slender, black, usually porrected 

 or pointed obliquely downwards ; eyes rough, black ; head 

 and thorax smooth, dull smoky-black ; fascicles very small, 

 dusky-white ; abdomen slender, black, dusted with pale 

 yellow, and each segment faintly edged with the same;
