was so on the alert that it tlew away again before a net could 

 be placed over it. Nevertheless there appears to be no 

 doubt that it also tlies at night, and its capture at light is 

 recorded. 



There appears to be no doubt that this species is a com- 

 paratively modern immigrant to this country. No mention 

 is made of it by our earlier authors. The first record appears 

 to be of a single specimen at Newhaven, Sussex, in 1855. 

 Four years later the capture of several specimens, sitting on 

 bramble leaves, on a hill-side near Wrexham, North Wales, 

 was announced, and the specimens were exhibited at the 

 Entomological Society in 1862. In 1868 one was recorded 

 as taken at St. Leonards, and another at Patcham near 

 Brighton; and in 1877 one at Bonchurch, Isle of Wight. 

 In addition to these, one at least has been secured near 

 Dover. But all these appear to have been merely casual 

 specimens — single immigrants, or specimens introduced in 

 some accidental manner — and the insect does not seem to 

 have effected a settlement in either of these localities. 



In August 1871 Mr. D'Orville of Exeter found a specimen 

 sitting upon a blossom of Tanacdum vuJgarc at night; two 

 years later others were taken at Hazel wood near Loddeswell, 

 Devon. In 1881 it was found at Dawlish. In 1882 the 

 species must have become firmly established, since Mr. AV. 

 Brooks states that the first specimen taken by himself at 

 Starcross, " excited no surprise as the inhabitants had seen 

 the species before." From that time to the present it has 

 been found year by year, and apparently in increasing 

 numbers, over that portion of Devonshire extending from 

 Exeter to Teignmouth. Eggs have also been obtained and 

 specimens reared by Mr. A. Robinson, of which beautiful 

 examples have been furnished for the purpose of this work. 



Although so recently settled in this country, it has long 

 been known to be common in the Channel Islands on the 

 coast of France. It ranges through Southern and Eastern 

 France, Holland, Belgium, Germany, and many parts of
