Lasiocampa. 129 



2. L. Pini (Linn.). — Fore-wings with the hind margin waved, grey, but varying much in depth 

 of colour, generally with a reddish-brown band at the base, and another beyond the middle ; a 

 white spot before the middle, and two or three dentated black transverse lines, the last of which 

 forms large curves ; the hind-wings are dark reddish-brown. Expands about 2 J inches. It is common 

 in pine-forests throughout Central Europe (except Britain) and Northern Asia from the end of June 

 to August. The larva, which is often very destructive, is ashy-grey, with red hairs, and brown 

 lozenge-shaped spots on the back, and brown stripes on the sides, blue transverse spots on the 3rd 

 and 4th segments, and a tubercle on the last segment but one. It feeds on Finns sylvestris from 

 autumn to the beginning of June. The transformations are figured at PI. 28, Fig. 3, a — c. 



* 3. L. rotatoria (Linn.), {Drinker Moth). — Wings with the hind margins slightly waved, ochre- 

 yellow, suffused with purplish-brown in the male, with two white spots before the middle, and 

 a brown line running from the tip to the inner margin. Expands from 2 to 2\ inches. Common 

 throughout the greater part of Europe and Northern Asia in June and July. The larva is dark 

 brown, with a yellow stripe broken into spots on the sides, and a black tuft of hair on the 3rd 

 segment, and also on the last but one. It feeds on grdss from autumn to June, and is one of 

 the most frequently observed and easiest reared larvae among our moths. The male, female, 

 and young larva are figured at PI. 28, Fig. 4, a — c. 



4. L. Lniiigera (Esp.), Lobnlina (Esp.). — Hind margins dentated, and fringes chequered with 

 black and white ; fore-wings dark grey, dusted with pale grey, with a white lunule in the middle, 

 and two black transverse stripes bordered with whitish ; hind-wings dark grey. Expands about 

 2 inches. It is found in Northern Europe and South Germany in August, but is a scarce and 

 local insect. The larva has tufts of hair on the back, and longer ones on the 3rd segment and 

 the last segment but one. It is blue or violet, with black spots on a yellow ground on the 

 back, and oblique yellowish streaks on the sides. It lives on fir-trees from autumn to June. 



5. L. Lincosa (De Vill.). — Fore-wings ashy-grey, with an oblique white band, bordered on 

 both sides with black, and sinuated and angulated externally, running from the tip to near the 

 base of the inner margin. There are two angulated black spots above it near the tip. The 

 fringes are white, spotted with black, and the hind-wings are uniform dark ashy-grey. Expands 

 about 2\ inches. It is found in South France and Spain in June. The larva feeds on cypress. 

 It hybernates, and arrives at maturity about the end of April. {L. Otits, Drury, from South- 

 Eastern Europe and Asia Minor, is the largest species of the genus, expanding 4J inches. The 

 wings are long and narrow, entire, and of a luteous-brown colour, the fore-wings with two denticu- 

 lated black transverse lines, and a dark patch near the base.) 



*6. L. Trifolii (W. V.). — Wings with the hind margins waved, brownish-red, or reddish-grey ; 

 fore-wings with a white central spot, and a curved whitish oblique streak behind. It is very 

 variable ; the variety Medicaginis (Borkh.) has rusty-brown wings ; in variety Codes (Hiibn.) the wings 

 are reticulated with yellow; and the \2.viQ\.y Retaincs (Herr.-Schaff.) has yellow fore-wings, with brown 

 bands. Expands from 2 to 2f inches. It is widely distributed, and not uncommon in Southern 

 and Central Europe and Western Asia in July and August. The larva is covered with thick 

 brownish-yellow felty hair. It has dark blue incisions, dotted \Ath. white, a yellowish streak on 

 the sides, and an orange-yellow head. It lives from autumn to June on grass and low plants. 

 (Z. Eversinanni, Eversm., from the Ural, is perhaps a variety of this. It is ochreous, with the 

 hind-wings darker, and the fore-wings have the fringes, a waved stripe near the middle, and a 

 ring in the middle brown. The larva is black, with yellow lines on the back, and yellow dashes 

 on the sides. The 2nd segment, and a broad stripe above the dashes, are orange. It is said to 

 feed either on scabious or on acacia.)
