but beyond the mere fact of the food-plant being found in England, we can find no reason to 

 consider this insect as a probable British species, as some authors have suggested. 



3. D. Zygophylli (Ochs.). — Fore-wings )-ello\\ish-green, with a narrow yellowish-white band 

 running from the base of the inner margin to the tip, emitting one or two short branches towards 

 the costa ; hind margin )-ellowish. Hind-wings crimson, with the base and a narr.ow marginal 

 line black. Expands 2\ inches. A scarce insect, confined to South-Eastcrn Russia. The larva 

 feeds on Zygophylliiin Fabago. 



*4. D. Euphorbice (Linn.). — Fore-wings grey, suffused with rosy, with a large olive-green spot 

 at the base, and another about the middle of the costa, generally followed by a smaller one. A 

 broad olive-green band rises from the outer half of the inner margin, and tapers obliquely to the 

 tip. Hind-wings red, with the base and a moderately broad stripe towards the hind margin 

 black ; the hind margin itself is flesh-colour. Under side red, with a black spot in the middle 

 of the fore-wings. Body olive-green ; the thorax with a white line on each side ; the abdomen 

 spotted with black and white on the first segments, and the hinder ones bordered with white ; 

 antenn.-E white. Expands about 2\ inches. Common in June and July in most parts of Central 

 and Southern Europe and in Asia Minor. It is a very rare insect in England, and is only found 

 on some portions of the southern and eastern coasts. The larva is black, dotted with yellow, with 

 a red stripe on the back, a red stripe spotted with yellow on the sides, and an intermediate row of 

 yellow spots. It feeds on spurge {Euphorbia Parnlias and Cyparissias) from July to September, 

 and is very conspicuous, feeding quite exposed on plants growing near the sea-shore, or at the 

 edges of fields and paths. The larva is seldom attacked by birds, to some at least of which it 

 appears to be poisonous. The moth and its larva are figured at PI. 18, Fig. i, a, b. 



5. D. Niccea (De Prunn.). — Very similar to Euphcrbicv, but much larger. Expands from 3^ to 

 3J inches. Fore-wings grey, rarely suffused with rosy ; base white, next to which is a dark green 

 band slightly bordered with white. Near the centre of the costa is a large dark green spot, and 

 nearer the tip are one or tw^o other costal markings ; near the hinder angle is a large dark green 

 band, which narrows suddenly, and branches off at almost a right angle to the tip. Hind-wings 

 black, with a central flesh-coloured band, having a white spot at the anal angle ; hind margin 

 broadl)' pale flesh-colour. Under side tinged with olive, and but slightly with ros\'. It is met with 

 in South France and Piedmont in June and September, but is not a very common species. The 

 larva is pale rose-colour, with two contiguous eyes on the back of each of the last ten segments ; 

 the rings are black, and the pupils orange. There is also a lateral row of orange spots, bordered 

 by two black ones. The head is rosy grey, the legs and horn black. It lives solitarily on various 

 species of Euphorbia, especially E. esii/a, from July to September. 



*6. D. G^fl/zV (Rottemb.), {Madder Hawk-moth). — Dark olive-green, the hind margin not much 

 paler. A rather narrow whitish stripe runs from the inner margin near the base to the tip. It is 

 irregular on the costal side, and throws off one or two short branches. Hind-wings as in Euphorbia', 

 but the red band is paler and much mi.xed with whitish, and the outer margin is narrowly whitish, 

 intersected by the black ner\'ures. The under side is grey, with the principal markings of the 

 upper side indicated ; and the antennae are dusky, tipped with white. The body nearly as in 

 Euphorbia:, with which this species agrees in size. It is common in a great part of Europe and 

 in Western and Northern Asia, but is a rarity in England, though the commonest of our three 

 British species. It is generally obtained by rearing from the larvse, which may be found at 

 various parts of the south coast. The larva is green, with a yellow stripe on the back, and large 

 round yellow spots on the sides surrounded with black. It feeds on bed-straw, willow-herb, and 

 fuchsia from July to September, and may be looked for especially on plants growing on coast
