LIST OF LEPIDOPTRRA PECULIAR TO THE BRITISH ISLANDS. 259 



previous stadium as being- beneath and slightly posterior to spiracle and 

 situated just above the lateral flange, is nearly or quite hidden, accord- 

 ing to circumstances (position, movement, etc.), by a fold in the skin 

 when at rest ; if the larva be disturbed or irritated, the larva retracts its 

 head and thoracic segments, lowers the flange, and discloses a large 

 deep red spot ; in the larger larviB this red spot is bordered with yellow. 

 The shagreen hairs are very short, and appear as small blunt cones on 

 lateral and dorsal areas ; on the ventral area, some few are hair-like. 

 Oblique stripes not strong but clearly marked when larva is at rest. 



General Notes. — The 4th stadium is the last, there being only 

 three moults as in Amorpha jmpuli. The larvre commenced to prepare 

 for pupation on June 11th. The larvae darken before going down, 

 the darkening consists of a dirty brown hue, and the dark colour 

 is developed in patches and not evenly distributed all over the larva. 

 This larva also voids a dark brown or greenish fluid with its faeces just 

 before going down as does that of Dinmrplia rersicolora. The warning 

 marking is rather a primitive affair compared with that of 

 Kinnorpha dpcnov or Theretra pnrcelliis, and is rather comparable 

 with the warning mark of Stauropiis fa(ji. It is, compared with 

 the thoracic spots of the larva of Lasiocaiii/ia qin'iri'is, less complex 

 in pattern, but of course larger, and probably in an active state of 

 development and use, while those of L. (jiii'rcitii are evidently under- 

 going atrophy ; the pocket in which it is hidden allows of a sudden and 

 startling display in A. tan, so that there is less need for elaboration 

 of colour design.

By .1. W. TUTT. 

 {Concluded from p. 205). 



GLYPHIPTERYGIDES. — Glyphipteryx thrasonella var. cladi- 

 ELLA, Sta. — From Deal to Shetland Isles. Certainly overlooked on 

 the continent. 



ARGYRESTHIIDES. — Argyresthia ^rariella, Sta. — Possibly an 

 almost unicolorous dark bronzy-fuscous form of A. copjiKjdla. 



A. sEMiFuscA, Haworth. — A quite distinct species ; local, but widely 

 distributed in England. 



Zelleria fusca, Sta. — Perthshire ; sunk by Rebel as Z. hcpariiila, 

 Sta. 



GELECHIIDES. — Bryotropha politella, Sta. — Widely dis- 

 tributed in England, Ireland, and Scotland. [Recorded doubtfully from 

 southern France.] 



LiTA PLANTACiixELLA, Sta. — Coast species ; England, Ireland, and 

 Scotland. Possibly overlooked on the continent. 



L. su.EDELLA, RicHDSN. — Another coast species, confined to the 

 coasts of England. Also possibly overlooked. 



L. iNSTABiLELLA, Sta. — Pretty widely distributed in England. 



L. BLANDULELLA, TuTT. — Local ; Only recorded from the Deal sand- 

 hills. Closely allied to L. xcDiidecaiidrflla. 



L. viscARiELLA, Sta. — Recordcd from England and Scotland. 

 ''Recorded also doubtfully from Hungary.] 



L. FEATERNELLA, DoTTGL. — Local ill England and Ireland. [Recorded 

 with doubt from south-west Germany.]
