94 LEPIDOPTERA. 



dorsal vessel; head black-brown; dorsal plate black, anal 

 plate green ; raised dots obscure but shining. 



May and June on Vaecinium myrtillus (whortleberry) in 

 the tops of the young shoots, uniting together the leaves 

 and eating them, but not boring into the shoot, making a 

 silken passage from shoot to shoot so that the plants become 

 distorted and disfigured. Also said to feed on V. uliginosum 

 and Erica caniea. 



Pupa slender, smooth, wing and limb covers glossy, seg- 

 ments less so, each segment with two raised rows of minute 

 teeth ; ere master pointed and furnished with a tuft of hooked 

 bristles. In a cocoon of white silk between two leaves of 

 its food-plant. 



This species is brisk and lively in the day-time, rising in 

 numbers from among Vacciniuin, buzzing about in the after- 

 noon sunshine, and till sunset, keeping almost constantly 

 close to the food-plant on moors, mosses, hill-sides, and in 

 woods in the south, but seldom seen away from it. Some- 

 times common on the hills of the south of Surrey, where the 

 Vaecinium grows, and in the New Forest, Hants ; in Kent, 

 Sussex, Dorset, Devon, and Herefordshire. More plentiful 

 in Staffordshire, Cheshire, Lancashire, Yorkshire, Durham, 

 and Westmorelaud ; in Wales on the hills of Pembrokeshire ; 

 in Scotland in Perthshire and Aberdeenshire ; and in Ireland 

 on the Wicklow mountains, in Sligo, Donegal, and Derry. 

 Abroad it is not always distinguished from the last species, 

 bat is known to occur in Lapland, and doubtless accompanies 

 its food-plant in other mountainous districts. 



Genus 18. PHLCEODES. 



Antennae ciliated ; palpi small and blunt ; thorax smooth ; 

 fore wings narrow, squared, strongly folded towards the base 

 of the costa ; apex rather pointed ; hind wings smooth.
