Necessarily confined to places where Juniper grows, but 

 probably occurring wherever the food plant is at all plentiful. 

 Baker and Tate, in their Flora of the Counties (Trans., vol. ii., 

 p. 252), say of Juniper — ''Scattered amongst the hill tracks from 

 the Cheviots to the Tees . . . and occurring also in the 

 Magnesian Limestone Denes, and sometimes amongst the Coast 

 Links." Coniferata or Simulata, as it is more frequently 

 called, is not an insect often met with except when specially 

 looked for. It sits in the day time on the Juniper stems, and 

 when beaten goes to the ground and sits on the fallen needles, 

 gently moving its wings up and down. Owing to the close 

 compact growth of the Juniper here on the coast, it is more 

 easily seen than dislodged, and the larvse are equally difficult 

 to obtain, but further west it grows more freely, and is there- 

 fore more accessible. My experience is that the larva is full 

 fed at the end of June, and the imago appears about the third 

 week in July, continuing on the wing till the middle or end of 

 August, but the dates given below differ considerably. Mr. 

 Bolam got a single specimen near "Windmill Hill on 10th 

 September, 1882 (Trans. Ber. Field Club, voL xv., p. 301). 

 This is certainly a very late date. The species is included in 

 the Twizell list, where no dates are given. Mr. Wailes "took 

 it" in Castle Eden Dene in June, 1834 (see Steph. Illust., 

 Appendix, vol. iv., p. 392). This is a very early date, unless 

 he obtained a larva, though the phrase quoted seems to refer to 

 the imago. Mr. Sang records having found it at Black Hall 

 Eocks on 27th July, 1862 ; at High Force, Dpper Teesdale, on 

 23rd July, 1873 ; and larvae at Wolsingham on 25th June, 1874. 

 At Wolsingham, Mr. Gardner tells me, the larvae are not at all 

 uncommon. We got the species regularly for many years at 

 Black Hall Rocks, though always sparingly, but the Juniper 

 has died off there during the last twenty years, and the Castle 

 Eden Dene locality is not easily accessible. The insect is 

 certain to occur on all the higher land from the Cheviots 

 southward. The "Manual" gives IS'ewcastle and Darlington, 

 but they both refer to captures at Castle Eden or Black Halls.
