green, and the lower, the white band, these two of about equal width ; 

 the four between taken together make up about the same width, and 

 are two pale lines, like the marginal band, but not white, as it has by 

 here faded into greenish, and two darker like the subdorsal green. It 

 is as though these lines were bits of the dark and white, moved apart 

 into the area of the other. The anal plate is pale, with broad dark central 

 line, bordered by a creamy, nearly white line. The clasper flaps green ; 

 head green, dappled with fine, darker, almost brown spots. The dark 

 larvae vary a good deal, and may be described as brown, olive, ochreous 

 or some similar tint. As a matter of fact the effect is the result of a 

 number of different tints, each of which varies from larva to larva. 

 There are precisely the same lines as in the green larvse. The dorsal 

 line is dark, sometimes nearly black. The broad dark subdorsal band 

 is ochreous or pink, marbled with dark brown, sometimes concentrated 

 so as to give a dark diamond mark on each segment something like 

 many Tephrodystis. The tubercle i is always conspicuous as a black 

 dot in a pale circle, ii is similar, but requires looking for. The pale 

 lateral band sometimes has a little white at its lower margin, but is 

 for the most part ochreous, flesh-colour, or pink. The fine dark line 

 immediately above it is generally nearly black, the next pale one pink, 

 the second pale one ochreous, and the intermediate darker one of 

 same tint as the broad dorsal one. Immediately below the pale 

 lateral line, there is a very dark, sometimes nearly black, sublateral 

 band, below which it is paler, with two pale ventral lines. In the 

 green ones, the sublateral band is dark green, the double ventral line 

 is also present. A very dark larva appears to be, broadly, almost 

 black dorsally, with the dark area widening in each segment, varying 

 through rich ochreous to nearly white at the margin, but with a lens, 

 the lines above described are seen, but in addition one notes that each 

 line varies a good deal in tone at each portion of each segment. The 

 head is pale, with some fine dark lines and spots. The anal flap 

 is a vivid pink (with central dark line) in most of the dark specimens. 

 The larva still has two attitudes, stretched out and given to tremulous 

 vibration, and curled round into rather more than a circle. At present 

 the larvfe are about 18mm. long by 2mm. wide, fairly uniform in 

 width, except the spread of the flap of the claspers. That a large 

 proportion of the larvae are dark and richly-coloured does not seem to 

 have been observed, the descriptions given being seemingly all taken 

 from Buckler, who only had green ones. His fed on the flowers of 

 Conopodiani,. It is possible that those that continued on the leaves, 

 on, or close to, the ground, are the dark ones. My larvfe had all 

 pupated before flowers appeared, and naturally, I suppose, flower- 

 heads are only available for full-grown larvfe. As to the foodplant, I 

 saw the moth this summer swarming in Switzerland in meadows, 

 where I could find no Conopodium, though other Umhelli ferae were 

 plentiful enough. It is not easy to convey by description the rich and 

 varied colouring of some of these dark larvfe, producing a rather dull 

 and earthy general effect, not unlike some of the darkest leaf-stalks of 

 the Conopodium, and, perhaps, harmonising still better with the earth 

 and dead leaves amongst which they grow. A census of the largest 

 larvse shows 28 green, 25 dark. 



The larvae, when quite full-fed, are about 21mm. long at rest, and 

 24mm. when stretched. On April 18th I note that they have been
