LITHOSIDAL. 229 



also, though far less commonly, in Devon, Somerset, Pem- 

 brokeshire, Herefordshire, Cheshire, and even Yorkshire, 

 where it has been found commonly near Scarborough. Dr. 

 F. B. White records it in Scotland, in Moray, but I know of 

 no record in Ireland, though it is difficult to believe the species 

 to be totally absent. The variety stramincola appears to be 

 confined to England, but the typical grey form is widely 

 distributed through the temperate portions of Northern 

 Europe, Central Europe, Northern Italy, and Finland ; also 

 in the Ural Mountains, Siberia, Tartary, and Japan. 



9. L. rubricollis, L. — Expanse, 1\ inch. Sooty-black, 

 with a red collar, and the abdomen tipped with orange- 

 yellow. 



Antennae threadlike, very slightly fringed with fine bristles 

 in the male ; black ; head smoky-black ; collar scarlet or 

 orange red ; thorax smoky-black ; abdomen black on the back, 

 from the base more than half its length, then light orange- 

 yellow. Fore wings long, not very narrow, and rather even 

 in width ; costa and hind margin gently rounded ; apex 

 blnnt ; dorsal margin nearly straight ; hind wings rather 

 broad, but not very ample ; apex blunt ; hind margin slightly 

 hollowed below it, then rounded. All the wings unicolorous 

 smoky-black ; when freshly emerged almost velvety black, 

 but soon fading a little. Female with simple antennaB ; 

 otherwise similar. Underside smoky-black, except that the 

 tongue, which is short, is pale yellow ; and the abdomen is 

 bright ochreous. 



I have seen but one variation — a male from the New Forest, 

 in the collection of Mr. F, N. Pierce, having hind wings of a 

 pale grey. Stephens records a specimen having an elongated, 

 naked patch on the fore wings, but this would simply be from 

 failure of the scales. It is a conspicuous and striking-looking 

 insect, totally unlike the other species in the genus, and, so far 

 as I know, having no very near allies in any part of the world. 



On the wing from the end of May to the beginning of July.
