the imago at Kag's Head near Darlington. We get the larvae 

 commonly about Hartlepool, but it is not so numerous as the 

 next species. A very constant variety, referred to above, occurs 

 regularly with the type, in which all the reddish markings ai'e 

 obsolete except the central spot.

 at sugar in autumn at Thornley," T. H. Hedworth; Thornley 

 Wood, Mr. Ehagg; '^ common in Upper Teesdale," P. A. Lees.

 This species appears late in autumn and hybernates, coming 

 out again in spring with the Tseniocamps. It is tolerably com- 

 mon in both counties and generally marked abundant. Around 

 Hartlepool, however, we find it far from plentiful. I never saw 

 it in the spring, and only occasionally in the autumn. Mr. 

 Gardner says, '* Hezleden Dene, at sugar in autumn, but not 

 common."
