86 European Butterflies and Moths. 



the female. Expands about l inch. It is found in Italy and the south-east of Europe and 

 in Asia Minor in June and August. The larva is ashy-grey with blackish warts, and is 

 yellowish-white beneath. It lives on vine in June and July, and is often very destructive in 

 vineyards. 



2. /. Prjini (W. v.). — Dark blackish-grey ; the thorax and fore-wings thinly scaled with 

 blue or greenish ; the hind-wings three-quarters of the length of the fore-wings. The antennae are 

 shorter than in the last species, with short pectinations in the male, and are serrated in the 

 female. Expands rather less than i inch. Common in most parts of Europe, except Britain 

 and the south-east, and in Northern Asia, from June to August. The larva is blackish-grey, 

 with an orange streak on the back, enclosing a black cross on each segment. It feeds on heath 

 in the north and on sloe in the south, and is much commoner than the perfect insect. It 

 may be obtained by beating sloe-bushes into an umbrella in May. 



3. /. Chloros (Hiibn.). — This species and /. Tenuicornis (Zell.) may be distinguished from any 

 of the following by their narrow fore-wings, which are of nearly uniform breadth ; the antennjE of 

 the male in Chloros are long and thickly pectinated, and the length of the pectinations is rather 

 suddenly reduced towards the extremity. Those of the female are slightly pectinated for two- 

 thirds of their length only. The fore-wings are unicolorous yellowish-green (or bronzy-brown 

 in the variety Scpiuni, Boisd.), except at the base, which, as well as the thorax, is of a beautiful 

 shining blue. Expands rather less than i inch. It appears to be confined to South-Eastern 

 Europe. 



4. /. Tenuicornis (Zell.) is a little larger than Chloros, and the fore-wings and thorax are of 

 a more or less greenish-blue. The antennse of the male are thickly and densely pectinated, and 

 end in an obtuse point ; they are much thicker than in Globnlarice and its allies. Those of the 

 female, which are only very slightly serrated towards the extremity, are also thicker and less 

 pointed than in the following species. It is confined to South-Eastern Europe and Asia Minor. 



* 5. /. Globularice (Hiibn.), {Scarce Green Forester). — In this and the remaining species with 

 pointed antennae, the fore-wings widen outwards considerably from the base. The pectinations 

 of the antennas are more slender, and diminish in length gradually, so that the antennje appear 

 more pointed than those of the previous group. The thorax and fore-wings of Globularics are 

 shining green or blue. The fore-wings are broad and thinly scaled, and are rounded at the tips ; 

 the hind-wings are grey, and are long and broad behind and very obtusely rounded at the tip. In 

 the female, which is always smaller than the male, the wings are often very short. The pectina- 

 tions of the antennae of the male are not very long, and lie close together ; towards the ends 

 they become very gradually shorter. In the female the antenna; are very slightly serrated for 

 about two-thirds of their length. The variety (i") Notata (Zell.) is more shining, often with a 

 golden lustre ; and the shaft of the antennae is more slender, with shorter pectinations, which are 

 often placed quite close together. Expands from three-quarters to one and a quarter inches. 

 This species appears to be found throughout Central Europe and Western Asia ; Notata is con- 

 fined to South Europe, and perhaps France. Globularice is an extremely local insect in the south 

 of England, but it occurs abundantly in a few localities on the chalk, in company with Geryon. 

 The larva is green, with reddish warts, and two zigzag straw-coloured lines on the back. It 

 mines in the leaves of Centaurea Scabiosa when young, and may be found feeding exposed in 

 May and June. The moth and larva are figured at PI. 21, Fig. 2, a, b. 



6. I. Cognata (Ramb.). — Fore-wings much less shining than in Globularice or Notata, with a 

 dull golden lustre. Only the thorax and a very small part of the base of the fore-wings are 

 brilliant green, and the hind-wings are darker than in Globularice. The pectinations of the
