Sp. 1. Myrtilli. AKs anticis rufo-ferrugineis, macula media strigisque Jlexuosis 

 albidis, posticis luteis, fimbria lata nigrii. (Exp. alar. 10 — 12. lin.)

Head and thorax reddish-brown, streaked with yellowish- white ; anterior wings 

 of a rich ferruginous-red, with various whitish undulated strigse, and whitish 

 fuscescent clouds ; the second and third ordinary strigge margined with dusky, 

 the former on its outer, and the latter on its inner, edge, forming a sort of 

 dolabriform fascia, in which is placed a conspicuous white spot of an irregular 

 shape ; the posterior striga is of a whiter hue than the others, and is very much 

 waved ; cilia fuscous, spotted with white at the apex : posterior wings luteous, 

 with a broad deep fuscous or black marginal band ; cilia luteous : abdomen 

 dusky, the margins of the segments whitish. 



Var. /3. With the anterior wings deep fuscous, with a riifous tint, with a small 

 pyramidal white spot, and a posterior waved white striga ; cilia and posterior 

 wings as in Var. «. 



In intensity of colouring, and the strength and position of the whitish strigte, 

 there is considerable variation. 



Caterpillar grass-green, with a bluish head ; each segment irregularly spotted 

 with elongate luteous and white marks, with an irregular black dorsal and 

 lateral line, the latter edged with white beneath ; it feeds on the whortleberry 

 (Vaccinium Myrtillus) and heath : — the imago appears the middle of June, 

 and continues to the end of July. 



This elegant insect is not uncommon in severaj parts of England, 

 though it appears to be rather local, and to frequent heathy and ex- 

 posed situations, where it may sometimes be observed flying swiftly 

 and irregularly in plenty " in the solar rays." I have taken it oc- 

 casionally near Darenth, and have received it from the New Forest, 

 and Devonshire : it also occurs in Norfolk. " York and Newcastle,
