354 BRITISH LEPIDOPTERA. 



as the specimens from Greece are concerned) is not only, not a variety 

 of pulla as it is generally catalogued, but is not even an Epichnopteryx, 

 since it possesses an anterior tibial spur as in the species of Psychidea, 

 to which it probably belongs. Chapman informs us that of two large 

 typical Italian examples (received from Eothschild) one has well- 

 developed cellula intrusa in the forewings, whilst the other has none, 

 and that a specimen of var. sieboldii has an extra nervure on one side. 

 Summarising our knowledge of the forms they appear to us to fall 

 roughly into the following : 



1. The large, 15mm. -17mm., densely scaled, intensely black, type form, with 

 21-22 joints to antennas, from Cannes (Tutt), Alassio (Chapman), Bergiin, Glogau, 

 Stettin, Schneeberg, Zurich (Brit. Mus. coll.) = pulla, Esp. 



2. A large, 14mm. -16mm., very well scaled (but rather less opaquely so 

 than the type), blackish (but with a grey tinge absent in the type) form, with 18 

 joints to the antennae, from Albula, Zurich, Silesia, Bergiin, Batisbon, Stelzing 

 (Brit. Mus. coll.). The very largest British examples perhaps fall here although 

 possibly rather less black = sieboldii. 



3. A rather smaller, 12mm. -14mm., well scaled, blackish form, with 18 antennal 

 joints, from Raibl, Preth, Posen (Hering's own examples) (Brit. Mus. coll.), and 

 exactly similar to some British specimens = heringii, Hein. (= ? pullisimilella, 

 Bruand). 



4. A variable, 10mm. -16mm., greyish-black form, paler, somewhat weakly scaled 

 and rather transparent, with brownish (or yellowish) tinge under lens towards apex, 

 with 17-20 joints to antennas, including most of our British examples, and a great 

 share of the central European ones = plumistrea, Haw. (= radiella, Curt.). 



The fact that certain of our larger British examples are indis- 

 tinguishable from the continental sieboldii (both in the larger size and 

 darker colour, which seem largely to be united in the same individuals), 

 and that many of the central European examples are as small, thinly 

 scaled, and pale as the greater number of our British examples, 

 suggest that these are identical, whilst individuals practically indis- 

 tinguishable from the south European type, appear to occur as aberra- 

 tions of (coming from the same localities as) sieboldii in various German 

 localities. We know nothing of the exceptionally large mountain form 

 silesiaca (which possibly is referable to the type form, although mountain 

 examples are usually small), nor of Bruand's innitidella, referred to 

 this species by Heylaerts and Kir by. Barrett says that specimens that 

 have been more worn in the middle of the wing tban at the margin 

 appear to have been mistaken for E. marginepunctella, Bruand, but we 

 are unable to trace any insect of this name allied to E. jyulla. 



a. var. silesiaca, Standf., " Ver. fur Settles. Ins. Zeits.," 1850, p. 55; Hofm., 

 "Berl. Ent. Zeits.," iv., p. 28 (I860); Snell., " De Vlinders," p. 440 (1882).— A 

 Psyche like E. pulla, only a third larger, also flew in the sunshine over Betula 

 nana, but as I am insufficiently acquainted with the species of Psyche, I do not 

 propose to raise it to the rank of a species, although I have sent it to friends under 

 the name of silesiaca (Standf uss). 



Wocke says that on the " Seefeldern" and the Iser meadows at the 

 end of June and in July a rare form is obtained, which is almost twice 

 as large as the ordinary form, and is mentioned in the magazines as 

 silesiaca, Standf uss. Hofmann observes that the insect known as 

 Fwnea silesiaca (of which he had a specimen from Wocke) from the 

 sea-plains of Beinerz, appears to him to be only a larger form of pulla, 

 and that he is unable to distinguish between the example sent him and 

 two equally large ones from Lahr.
