158 LEPIDOFTERA. 



Extraordinarily abundant in many parts of the South of 

 England, and so plentiful in the outskirts of London that it 

 is, in some years, quite usual to see specimens sitting about 

 in the day-time on tree trunks, or in the corners of walls, in 

 the thickly populated streets, where they have quite evidently 

 lost their way. Plentiful in suitable places throughout 

 England as far north as Yorkshire and Lancashire, but less 

 common further north, and scarce, or very local, in Scotland, 

 where, however, it is known to occur in the Glasgow district ; 

 in Perthshire, not commonly ; in Aberdeenshire ; and has even 

 been taken in the Orkneys. There seems to be a scarcity of 

 records in Ireland. Mr. E. Birchall stated that it was 

 common everywhere there, but this was evidently a mistake, 

 as it seems to be unknown in the north of Ireland. I have 

 myself taken it in the County Galway, and have no doubt that 

 it is existent, if not plentiful, in many more southern districts. 

 Abroad it is found in the Alps and in various other parts of 

 Central Europe, in Southern Sweden, and Dalmatia. 



3. H. sylvinus, L. — Expanse, male 1 to \\ inch, female 

 \\ to 2 inches. Fore wings orange-brown or dark chestnut, 

 with two whitish transverse stripes meeting on the dorsal 

 margin ; hind wings brown, edged with orange-red. 



Antenna) very short, yet with distinct pectinations ; head 

 and thorax of some shade of orange-brown in accordance with 

 the colour of the fore wings ; abdomen pale brown. Fore 

 wings slightly broader than in the preceding species, with 

 the hind margin rather more oblique, and the anal angle 

 even more rounded off. Colour, in the male, orange-brown, 

 or orange-ochreous, marbled with pale fulvous ; a slightly 

 paler basal space is edged by an oblique, partially transverse, 

 silvery-white stripe, edged with purplish-grey, which proceeds 

 from the median nervure, near the base, to the middle of the 

 dorsal margin, where it almost meets another white stripe, 

 also edged with purplish-grey, which crosses the wing
