114 CATALOGUE OF MOTHS. 



except at Hartlepool. Both Mr. Gardner and I have frequently 

 taken it at Eagwort flowers on the sandhills. In August, 1876, 

 it was comparatively common, and I took a good number. A 

 year or two later it disappeared and I thought it had left us 

 altogether, but in 1894 I went about a mile further north than 

 my usual collecting ground, and found it sparingly on E-agwort 

 flowers as before. Mr. Barrett thinks Yorkshire the limit of its 

 northward range, and the Hartlepool sandhills are but a few 

 miles beyond. The insect is too regular in its appearance to be 

 a visitor, but its scarcity, and the fact that the Sunderland col- 

 lectors have not met with it, seem to fix our sandhills as its last 

 northward stage.

A common species in many parts of our district, but nowhere 

 so abundant as pronula. It is in the Twizell list ; Mr. Tinlay 

 took it all over the Morpeth district but not commonly ; all the 

 Newcastle collectors found it at Jesmond and elsewhere about 

 l^e wcastle. Mr. Hed worth met with it in all parts of his district ; 

 it is in the list in Ornsby's Durham ; Dr. Lees took it in Upper 

 Teesdale, but not abundantly; Mr. Backhouse at Barnard Castle 

 and Darlington ; Mr. Boss took two at Bishop Auckland. At 

 Hartlepool it occurs regularly but never in large numbers. It 

 is a very variable species and sometimes grandly marked, but 

 the best forms, known as Curtisii, occur chiefly in the north of 

 Scotland. "With us the ground colour of the fore-wings is the 

 most variable portion. Yery pale forms are sometimes met with 

 here, and occasionally they are rather reddish, but the stigmata 

 and lines are seldom well marked.
