Zyg^na. 89 



about i\ inches. Local in woods in the greater part of Europe, except the north-west, and in 

 Northern and Western Asia. In the south it appears to be confined to the mountains. The larva 

 is golden-yellow, with whitish hairs, and three rows of black spots on the back, and a black head. 

 It feeds on clover, but attaches its cocoon to tree-trunks ; and if the cocoons are removed, the 

 surrounding bark must be taken with them, or the moths will not be successfully reared. The 

 moth is figured at PI. 21, Fig. 5. 



5. Z. Romeo (Dup.). — Fore-wings black and densely scaled, with a broad longitudinal streak 

 beyond the middle, which is thickened into a club behind ; a shorter one on the costa, a small 

 spot between both, and a larger round spot on the disco-cellular nervule. These markings, as 

 well as the hind-wings, which have a broad blackish border, are dark carmine-red. The club of 

 the antennae is long. Expands from i to \\ inches. It seems to be common in Spain and 

 throughout the Italian peninsula, from the Southern Alps to Sicily, but, strange to say, it does 

 not appear in the French lists. 



6. Z. Sarpcdon (Hiibn.). — Wings bluish or greenish, almost transparent, with two red spots 

 running from the base, of which the lower one is three times as long as the upper, and is often 

 interrupted; and a round spot near the tip. There is often a fourth small spot at the bifurcation 

 of the principal nervure. The hind-wings are more or less suffused with red at the base, and there 

 is a red belt on the upper side of the abdomen near the tip. It expands i inch or under. The 

 variety Balearica (Boisd.) is still paler, with larger spots, and the base of the inner margin is red. 

 This species inhabits South France, Piedmont, and Spain, and the larva feeds on Eryiigiuni 

 cauipestre. (Z. Contaminei, Boisd., much resembles this, but is less transparent, and the red belt is 

 almost or entirely absent. It expands i-^ inches, and is found in the Pyrenees and in Spain. Its 

 larva feeds on the same plant as that of Sarpedon, from which Contaminei is perhaps not truly 

 distinct.) 



7. Z. Punctuin (Ochs.). — Wings thinly scaled, blackish-grey, with carmine-red stripes, and 

 spots arranged as in Romeo, which are generally suffused, and the spots are sometimes united by a 

 narrow streak. The hind-wings are carmine, with the hind margin narrowly blackish ; the thorax 

 has pale grey hairs, and the club of the antennae is thick and obtuse. Expands about i inch. 

 It inhabits the south of Europe, except Spain, and Western Asia. 



8. Z. Achillea; (Esp.). — Fore-wings blackish-blue or greenish-grey, with five large carmine- 

 red spots, the last of which is kidney-shaped and very large, being composed of spots 5 and 6 

 united ; the hind-wings are carmine-red, with a very narrow black border ; the club of the antennae 

 is short and obtuse, and the abdomen is sometimes marked with an indistinct red belt. Expands 

 from I to I J inches. It is common in many parts of Southern and Central Europe, except Spain 

 and the north-west, and in Northern and Western Asia, occurring in dry places, especially on a 

 limestone soil. The larva is greenish-yellow, with a pale line on the back, and two small black 

 dots at the front and back of each segment ; head black. It feeds on Astragalus glycyphyllos and 

 Coronilla varia. The moth is figured at PI. 21, Fig. 6. 



9. Z. Cynarce (Esp.). — Fore-wings thinly scaled, and blackish-blue or green, with brownish 

 fringes, and five separated carmine-red spots ; hind-wings carmine-red, with the tips blackish. The 

 abdomen is marked with a broad red belt, and the club of the antennae is long and thick and 

 rather obtuse. It expands nearly i\ inches, and inhabits South-Eastern Europe and Western 

 Asia. {Z. Anthyllidis, Boisd., is a scarce species found in the high Pyrenees, with six large red 

 spots more or less bordered with yellow, and a red belt on the upper side of the abdomen only. 

 Expands \\ inches.) 



* 10. Z. Exulans (Hoch.).- — Fore-wings thinly scaled, of a greenish or bluish-grey, with five
