is locally pleatifnl, aud is not scarce iu Yorkshire, Durham, 

 Northumberland, and Cumberland. In Scotland it is found 

 in Perthshire to 600 feet above the sea level, and is distri- 

 buted over the more southern portions of that country. In 

 Ireland more common and has a wide range, being frequent 

 so far north as Belfast. 



xlbroad it is found throughout Central Europe, the tem- 

 perate portions of Northern Europe, Italy, Southern and 

 Eastern Turkey, Southern Eussia, Asia Minor, Armenia, 

 Eastern Siberia, aud the mountainous regions of Central 

 Asia. 



(li. l-album, Z. — This is a pretty species, somewhat 

 resembling L. comma, but of a more neat aspect. Its most 

 striking character, from which it takes its name, is a |distinct 

 white line upon the median nervure, which turns up at the 

 end of the discal cell and forms a white letter /. It is 

 an abundant species in Southern and some parts of Central 

 Europe, extending into Armenia and Asia Minor, and becoming 

 very plentiful in the more hilly districts of India. Forty 

 years ago (1857), Mr. Stainton, when recording the first 

 occurrence of an allied species, made the unfortunate remark, 

 "How long are we to wait for Lcucania l-alhumV A few 

 years later some enterprising collectors, considering that the 

 time had arrived when this question should be answ^ered, 

 announced the capture, first of one, but afterwards of more, 

 specimens in Kent. But the matter was carefully investigated 

 by the late Mr. H. Doubleday, and the whole transaction ex- 

 posed. No further captures have been announced, and there 

 is not the smallest reason to believe that the species has ever 

 been an inhabitant of this country. 



Another allied species, L. commoidcs, was announced about 

 the same time from the same district, but was soon proved to 

 be a North American insect.)
