The caterpillar of this butterfly may be taken by beating the black thorn 

 bufhes, that grow in old hedgerows, into a iheet, or cloth, fpread under the 

 bum to receive them. The beft time to beat for thefe caterpillars is the latter 

 end of May, when they are nearly at their full growth. Thefe caterpillars are 

 very Angular in their form, and at firft fight appear like woodlice, lying flat 

 on a leaf or twig, without the leaft fign of feet ; and when they travel, their 

 motion is more like that of a Aug than that of a caterpillar. They arrive at their 

 full growth, as at fig. 1, the firft week in June ; and prepare for their meta- 

 morphofis by fixing themfelves to a flender branch, or twig, of the bufh they 

 are on, with a web round the middle, and by the tail. In a ihort time after- 

 wards the chryfalis is perfect, as at fig. 2. The middle of Augufl: afterwards 

 the male butterfly comes forth, and appears on the wing, as at fig. 3. The 

 female is nearly fourteen days longer before it comes from the chryfalis, fee 

 fig. 4; and for the under parts fig. 5. This infect is very far from common; 

 but the fly may be taken on the tops of hedges, and particularly on the maple 

 tree, on which it delights to fettle. 



The butterflies of this feclion are named hair-ftreaks from the fine line of 

 white eroding the wings on the under fide.
