Larentia. 371 



with brown ; costa pale yellow ; hind-wings yellowish. Expands about I inch. Common in 

 Central Europe, and in Northern and Western Asia, in July and August. The larva is pale 

 green above, and dark green on the sides, with a whitish lateral stripe. It feeds on rose in 

 May. The moth is figured at PI. 48, Fig. il. 



*I2. L. Firmata (Hiibn.). — Fore-wings light violet-grey, pale rusty-brown in the basal and 

 central areas, the latter with a pointed excavation in front, and bordered by a darker line ; 

 the tip, hind margin, and paler hind-wings without markings, and the antennse of the male 

 pectinated. The variety Ulicata (Ramb.) is violet-grey, with a brown central band. Expands 

 from I to I J inches. Inhabits Central and Western Europe from May to September. The 

 larva is grass-green, with a yellow line on the sides, and small reddish-brown spots on the 

 front segments. It feeds on fir in April, June, and July. (L. Scrraria, Zell., from Northern 

 Europe, has fawn-coloured fore-wings, with the outer fascia and angulated lines w^hite, and an 

 oblique black central spot ; hind-wings bordered with grej'.) 



*I3. L. Variata (W.V.). — Very variable in colour and markings; fore-wings whitish (variety 

 Stragtdata, Hiibn.), brownish-grey, or yellowish-brown, with the basal and central areas dark 

 greyish-brown, or fawn-colour (variety Obdiscata, Hiibn.) ; the central area bordered by dark 

 lines edged with whitish, and with a slight rounded projection behind, projecting furthest in 

 cell 6, and much narrowed towards the inner margin ; the tip divided by a short dark dash, 

 and the hind margin dotted with black ; hind-wings with a darker cur\-ed line, bordered 

 with pale, and curved rectangularly in the middle. Expands from i to \\ inches. Inhabits 

 Europe and Siberia from June to August. The lar\ a is green, with white lines on the back 

 and sides ; it feeds on fir in April and IVIay. 



*I4. L. Jimiperata (Linn.). — Very like grey specimens of Variata, but smaller (expands 

 about 1 inch) ; fore-wings narrower and of a purer ashy-grey, and rather darker brownish- 

 grey at the base and in the central area ; no subterminal line, and the marginal spots finer 

 and more like an interrupted line ; the hind-wings are considerably longer on the costa than 

 on the inner margin, and are pale grey, with a darker cur\'ed line, forming a rectangle in the 

 middle. Common in Central Europe in October and November. The lar\'a is green, with a 

 double yellow line on the back and a red stripe on the sides, bordered with white below. 

 It feeds on juniper in July and August. 



*I5. L. Siinulata (Hiibn.). — Much like the last two species, the wings shaped as in Jiiniperaia. 

 Fore-wings are brownish-grey, with the basal and central areas darker, and bordered by dark 

 brown lines edged with whitish ; the central area not much broader on the costa, and with the 

 edges scarcely dentated, only projecting into an acute angle beyond the central spot, and inter- 

 sected by two dark lines ; the pale subterminal line is interrupted, the hind margin dotted with 

 black, and the hind-wings marked with an obtusely angulated central line beneath. Expands 

 about I inch. Inhabits Northern and Alpine Europe in July. The larva is green, with three 

 whitish lines on the back, and a white line on the sides, bordered with red above. It feeds on 

 juniper in June. 



16. L. Ciipressata (Geyer). — Resembles Variata ; fore-wings reddish-grey, with the basal and 

 central areas darker grey, the latter only distinctly bounded on the costa, and with rather slight 

 projections, and very narrow at the inner margin ; subterminal line indistinct, and with three 

 black dashes behind below the tip. Expands a little more than i inch. Inhabits South France 

 and Bithynia in October and November. The larva is green, paler below, with a dark green line 

 on the back, and a zigzag white line below. It feeds on juniper from May to October. 



*\~. L. Ccrylaia (Thunb.). — Fore-wings whitish, varied with olive-grey, and finely dusted with
