covers, liead, and dorsal region, closely covered with tiue 

 sculpture of prominences and pits, and similar sculpture over 

 tlie anterior portion of each abdominal segment, but the 

 hinder portion of each segment smooth and glossy and 

 forming a hoop-like band ; anal segment produced into a 

 broad flattened black cremaster, underneath which the 

 segment is hollowed out ; its tip furnished with a double 

 spike, the two points of which diverge widely and are 

 slightly hooked beneath ; general colour dark purple-brown. 

 In a slight brittle cocoon of earth and silk, beneath the 

 surface of the ground. In this condition through the winter. 

 The larvEe and pupaa for these descriptions were furnished by 

 Major A. Ficklin. 



The moth sits in the daytime on fences, rails, posts, or the 

 trunks of fir trees, appearing to like an exposed situation. 

 It flies at dusk and comes willingly to sugar, but is not often 

 captured by other attractions. Kather a widely distributed 

 species, but rarely common ; apparently most frequent in 

 Northamptonshire and Worcestershire. Known to occur in 

 Kent, Sussex, Surrey, Hants, Berks, and Oxfordshire ; more 

 rarely in Dorset, Devon, Somerset and . Gloucestershire ; 

 perhaps a little more frequently in Essex, Suffolk, and 

 Norfolk, but more rarely in Cambridgeshire; also found in 

 Herefordshire, very rarely in Yorkshire, and recorded thirty 

 years ago in Cheshire. I find no record in Wales ; in Scotland 

 it seems to have occurred near Paisley, at Troon, Ayrshire, 

 and in Argyle. In Ireland Mr. E. Birchall recorded it as 

 uncommon in Wicklow, but there is some doubt about the 

 correctness of this record, and also about another in West 

 Meath, Abroad it does not appear to have a northern range, 

 but is found throughout Central Europe, Spain, Northern 

 Italy, Livonia, Southern Russia, Eastern Siberia, and the 

 Mountain regions of Central Asia.
