bloom of tlie tall sallow bushes, and is one of the first species 

 to be found at them in the spring. Moreover, it will brave 

 the wildest storms in pursuit of this favourite food if the 

 weather is not cold. I well remember a most tempestuous 

 night toward the end of March, when the furious wind was 

 blowing the bushes in every direction, and gusts of rain 

 added to the tumult, that in a somewhat sheltered wood I 

 saw in the course of the evening not less than 150 indi- 

 viduals of this species clinging to, and feeding on, the wet 

 and swaying branches of fresh bloom. On no other night 

 did I ever see one-fourth of this number, and the only con- 

 clusion to be drawn was that this kind of weather suited the 

 insect. It may be taken occasionally at sugar, certainly 

 more frequently than any other of our species of this genus, 

 and also frequents the blossoms of blackthorn and plum. 



Principally confined to woods or districts abounding in 

 trees, and in such situations found apparently throughout 

 England, except some portions of the Midland counties and 

 Northumberland and Durham, from which I have no records ; 

 but common only in the South of England. Probably in 

 the valleys of all parts of Wales, though the only records 

 seem to be in Glamorganshire, Carmarthenshire, and Pem- 

 brokeshire — but in the last scarce. In Scotland Mr. Adam 

 Elliot has taken it in Roxburghshire, and Dr. Buchanan 

 White mentions it as very local in the districts of the Tweed 

 and Solway. In Ireland Mr, Kane records that it is widely 

 distributed in the aortli and scarce in the soutli ; the localities 

 noted are Dublin, Wicklow, Kerry, Galway, Sligo, Louth, 

 Monaghan, Tyrone, Enniskillen, and Cavau. Abroad its 

 range is through Central Europe, Livonia, Southern and 

 Eastern Russia, the mountain regions of Central Asia, and 

 Japan,
