218 SPECIES OBSERVED BY THE AUTHOR 



I have thus described it : 



Length 9 lines ; green, dorsal vessel slightly darker (the full- 

 grown larvae show indications of a slightly darker subdorsal line) ; 

 spots small, black, in pale green rings ; head black ; anterior edge 

 of second segment reddish brown ; posteriorly this segment bears two 

 large black lunate plates, scarcely divided in the centre ; anal seg- 

 ment pale green ; anterior legs yellowish. 



A younger larva, about 2 lines long, was yellowish-green, with 

 the head black ; the second segment reddish brown-black, and the 

 anterior legs black. 



Before dispersing my series of bred specimens, I made the follow- 

 ing description of the imago : 



Exp. al. 10-11 lin. Head, face, and thorax brownish grey, some- 

 times almost reddish brown ; palpi with the second joint externally 

 brownish, or reddish brown, internally paler, terminal joint yellow- 

 ish, with two faint brownish spots. Antennae fuscous, rather more 

 than half the length of the anterior wings. 



Anterior wings brownish grey, varying slightly in intensity, and 

 sometimes with a reddish tinge, with two conspicuous black spots on 

 the disk before the middle ; the upper one, rather anterior to the 

 lower one, is round ; the lower one is elongate ; from it proceeds a 

 slender yellow streak nearly to the hind margin ; beyond the middle 

 it shows a tendency to form a yellow spot, immediately after which 

 in some specimens it is slightly interrupted ; a similar slender yellow 

 streak runs along the fold from near the base to about the middle of 

 the wing, and in some few specimens a yellow streak runs a little 

 way along the subcostal nervure; there is also a slender yellow streak 

 along the inner margin to the anal angle, more distinct in some 

 specimens than others. 



But the most striking feature of the insect is furnished by the 

 great number of short transverse pale streaks, which in those speci- 

 mens with the darkest ground-colour are extremely conspicuous. It 

 is very possible that this character is easily lost by specimens which 

 have been long on the wing, as I find that in one of my bred specimens, 

 which had slightly damaged itself amongst the debris of Ruta at the 

 bottom of the box, these transverse markings have almost disap- 

 peared ; in one solitary uninjured specimen they are extremely faint. 



In some specimens a faintly indicated darker cloud crosses the 

 wing obliquely (as in angelicella} beyond the middle ; the palest por- 

 tion of the wing faintly indicates the position of the pale hinder 

 fascia ; form of the hind margin nearly as in D. atomella-, cilia rather 

 redder than the ground-colour of the wing. 



Posterior wings pale grey, with greyish- ochreous cilia. 



Depressaria atomella, S. Y. I noticed the larvae of this species at 

 Cannes on the Calycotome spinosa, February 28th. 



Depressaria nodiflorella, Milliere. (See ante, p. 175.) When 

 visiting the He Ste. -Marguerite, near Cannes, on the llth March, 

 one of my great desires was to find some of the larvaa of the Depres- 

 saria which feeds on that magnificent Umbellifer, Ferula communis,
