and cylindrical ; greenish-yellow, with longitudinal rows of square black spots, and round ones 

 below them, on each side. It feeds on Dorycninm. 



16. Z. Angelicce (Ochs.). — Fore-wings densely scaled, of a dark greenish-blue, with five, and 

 more rarely six, carmine-red spots, which are united on the under side by a longitudinal streak 

 dusted with red ; the two spots in the middle are very oblique, separate, round, and of equal 

 size ; the hind-wings are dark carmine-red, with a broad blackish border, and the club of the 

 antennae is long and pointed. E.xpands a little over i^ inches. It inhabits Eastern and Southern 

 Europe, except Spain. The larva, which feeds on Trifoliuin nioutaintni, is yellow, with two rows 

 of black spots on the back. 



17. Z. Trmisalpina (Esp.) is perhaps only a variety of the last, but has always si.x red spots, 

 which are narrowly bordered with black, and the colour of the spots and hind-wings is of a purer 

 carmine-red. It inhabits the Southern Alps. 



18. Z. Hippocrcpidis (Hiibn.) is also very like the two last species, but the spots of the fore- 

 wings are not surrounded with black ; the hind-wings have a narrow black border, and the red is 

 of a bright cinnabar colour, with which the whole of the under side of the fore-wings is suffused as 

 far as the dark borders. Expands about \\ inches. The larva has a blackish line on the back, 

 and a yellow line on the sides, with triangular black spots between. It feeds on Astragalus 

 glycyphyllos. This species is common in many parts of Central Europe, and has been reputed 

 British, probably in error. It frequents dry, sunny localities. 



* 19. Z. FilipendidcB (Linn.), (Six-spot Burnet). — Fore-wings rather thickly scaled, blackish-blue 

 or green, with six crimson spots, the two middle ones placed close together and a little obliquely ; 

 on the under side the fore-wings are very slightly suffused with pale reddish-yellow ; hind-wings 

 crimson, with a narrow black border ; the club of the antennae long and thick. In the aberration 

 Chrysantlioiii (Borkh.), the crimson markings are replaced by coffee-brown ; and in another 

 aberration, which seems not to be very rare near Cambridge, they are replaced by rich yellow. 

 The Alpine variety J\famni is more thinly scaled, and all the colours are duller; and in the variety 

 Cytisi (Hiibn.), and in the Greek variety Ramdurii (Led.), the si.x spots run together into three large 

 ones; and in the latter the spots are more of an orange-red. Expands from i to ij inches. This 

 species is one of the commonest of the genus, and abounds throughout Europe (except South 

 Spain and the Polar regions) and Western Asia, though not so common in some localities as 

 Trifolii. It frequents meadows, flowery slopes, &c. The larva is golden-yellow, with two rows of 

 black spots on the back, and a row of smaller ones on each side. It lives on clover and other low 

 plants, and is figured, with the moth, at PI. 21, Fig. 10, a, b. 



20. Z. Ochseitheiineri (Zell.), Trausalpina (Ochs.). — Fore-wings bluer than in Filipendulce ; 

 spot 6 divided by a black nervure, and the yellowish suffusion of the under surface fainter or 

 absent. The hind margin of the hind-wings is more or less strongly blackish-blue, and is distinctly 

 concave. Expands if inches. It is probably a large variety of Filipendulce, and occurs in the 

 Southern Alps. 



21. Z. Ephialtes (Linn.). — Fore-wings blackish-blue, with five or six spots ; the abdomen with 

 a broad belt ; the club of the antenna; slender and pointed, with the tip narrowly whitish. This 

 species presents so many constant named variations in colour and markings that it will be 

 necessary to describe them separately. In CoronillcB (W. V.) the fore-wings have six white spots, 

 of which the two at the base are dusted with ochre-yellow. The hind-wings are black, with a 

 round white spot towards the tip, and the abdomen is belted with yellow. It is figured at PI. 21, 

 Fig. II, rt. The true Ephialtes (Fig. 11, b) differs from this by having the basal spots of the fore- 

 wings and the belt of the abdomen red instead of yellow. In Peiicedaiii, Esp. (Fig. 11, <), the six
