semicircle, on each side of the head. Prothoracic segment decidedly narrower than 

 the succeeding ones, with a slightly polished pale yellowish-green undivided plate, 

 on which are several minute black polished dots emitting brownish bristles. Thoracic 

 segments and abdomen together of the usual Depressaria shape, of fairly uniform 

 width in the middle and tapering thence towards both extremities, somewhat semi- 

 transparent pale yellowish-green ; the dorsal vessel shows distinctly as a dark green 

 central line through the entire length from behind the prothoracic segment, and on 

 either side of it is a broad but ill-defined rather dark gi-een subdorsal line ; skin 

 smooth, rather glossy. Warts and spiracles polished, black, emitting brownish 

 bristles. Anal plate inconspicuous, slightly polished, greenish-yellow ; its surface is 

 remarkably uneven with several black polished raised spots, emitting brown bristles, 

 standing on distinct mound-like prominences. Ventral surface pale yellowish-green 

 with some minute black polished warts. Legs semitransparent, yellowish watery 

 white. Prolegs semitransparent, watery-white. 



I have as yet only found the larva living in a slight silken web 

 among, and feeding or\, flowers and young seeds of Conopodium denu- 

 dafum, Koch (= Bnniumflexuosum, AVith.), from flowers of which it 

 was bred years ago by Dr. Colquhoun (Ent. Ann., 1856, p. 51 ; 1858, 

 p. lOG). It also feeds on other plants, and sometimes adopts different 

 habits, for von Ileinemann bred the imagines, which were duly iden- 

 tified by Stainton (Ent. Ann., 1870, p. 8), from larvae found by himself 

 in rolled-up radical leaves of Pimpinella saxifraga, as recorded in 

 Schmet. Deutsch. u. d. Schweiz, iii, 181, where he adds that, according 

 to Schmidt, it feeds on Valeriana officinalis. Besides the above, 

 Sorhagen (Kleinschmet. d. M. Brandenburg, 329) mentions Cnidium 

 vetiosum and Dauciis, but does not give his authorities for these food- 

 plants, and both he and Meyrick (HB. Br. Lp., 629) speak as though 

 the invariable habit of the larva is to live in rolled leaves, which is 

 certainly not the case. 



PUPA. 



The pupa was thus described on June 8th, 1896, after it had been 

 in that state only a few days : — 



Length, 7 mm. Greatest breadth, 26 mm. 



Very broad anteriorly, gradually tapering posteriorly, flattened dorsally. Skin 

 smooth and highly polished ; hairs and bristles pale and inconspicuous. Eyes 

 showing through as indistinct dark spots. Antennal cases lying between, and of 

 equal length with, the wing-cases. Head and prothoracic segment dingy reddish- 

 orange. Meso- and meta-thoracic segments dingy greenish-orange. Wing-cases reach- 

 ing to the end of the fourth abdominal segment, dingy greenish-orange, as are also 

 the limb-cases. Abdomen dorsally dingy orange slightly tinged with green ; on its 

 second and following segments is a green dorsal line, becoming less distinct posteriorly ; 

 segmental diyisions clearly defined ; anal segme;it orange-red, armed with some 

 orange-coloured hooked bristles. Ventral surjace to end of wing-cases dingy greenish-
