MAS0NIA. 305 



pilis longissimis obtecto. Pedibus flavo-griseis, tibiis anterioribus spina magna 

 adhsBrente. Alarum fimbriis flavo-albidis, nitidis, ad basin obscurioribus. Alis 

 anterioribus costis 11, cellulse discoidalis cellula magna intrusa*. Exp, al. 16mm.- 

 20mm. Femina. — Etiam F. crassiorellae, Brd., ? similis, omnino tamen flavo- 

 grisea ; capite parvo, brunneo-griseo nitido ; oculis magnis compositis ; antennis 

 flavo-albidis, fere hyalinis. Segmentis 3 primis supra flavo-brunneis nitidis ; 

 segmentis abdominalibus supra macula quadrangulari brunnea, nee nigra ; ultimo 

 segmento pilis longissimis, albidis nitidisque obtecto ; oviducto articulato. Pedibus 

 flavis fere hyalinis. Larva. — F. crassiorellae, Brd., larvae similis; capite tamen 

 nigro strigis luridis ; thoracis segmentis strigis latioribus nigris ; abdominis 

 segmentis magis ferrugineis. Involucrum. — Breve, cylindricum, paleis longitrorsum 

 obtectum. Habitat.— Norvegia (et ? Suecia) montana ; Gallia meridionalis (Alpes- 

 Maritimes) (Heylaerts, " Gomptes Rend. Soc. Ent. Belg." xxvi., p. cxl). 



Although B. norvegica was first made known (by publication) by 

 Schoyen, he evidently used a name that had been previously given (in 

 MS.) by Heylaerts. Schoyen notes (Ny't. Mag. Nat., 1880, p. 303) 

 that " both the examples referred to by Schneider in Enum. Ins. Now., 

 iii., p. 36, under the name of F. nitidella, Hb. (intermediella, Brd.), and 

 several others from the University collection found at Christiania, by 

 Professor Esmark, have been determined by Dr. Heylaerts as belonging 

 to this species (crassiorella) which, as far as is known, has been previously 

 recorded only from southern and central Europe. One of the examples 

 1 cum cellula intrusa ' is named var. norvegica by Dr. Heylaerts, who 

 considered that it might prove to be a distinct species." Heylaerts him- 

 self, although including it in his 1881 list as a distinct species, did 

 not describe the insect till 1882 and then states that he did so from " two 

 examples from a little collection in the Christiania Museum and 

 another from Staudinger, all three having been captured in Norway." 

 He further notes that "in July 1880, some cases, with larvae, were 

 received from Milliere, that had been taken at St. Martin Lantosque ; 

 from these, between July 20th and August 10th, a $ and ? emerged," 

 and Heylaerts expresses his surprise at finding that they " belonged to 

 a species hitherto considered as exclusively Norwegian." He later 

 recorded two typical examples from Ordoubad in Transcaucasia.

* As there was some doubt whether our scotica might possibly be the same as 

 Heylaerts' norvegica, although it has no cellula intrusa, Dr. Chapman wrote to him, 

 and Heylaerts in reply said : " Norvegica is a distinct species, and it has always, 

 in France and Norway, the cellula intrusa. . . . the latter is by no means 

 characteristic of the crassiorella group, for the last named species does not possess 

 it nor do intermediella and nitidella " (in litt., Dec. 18th, 1899). Schoyen notes the 

 example in the Christiania Museum that Dr. Heylaerts examined as "an old one 

 captured June 24th, 1879, possessing the cellula intrusa, and apparently with 20 

 joints to antennse (but the number is doubtful) ; the tibial spine difficult to measure 

 but looks to be about one-half the length of the tibia" (in litt., January 12th, 1900). 

 Heylaerts further notes that norvegica "is a very rare species with rather elongated 

 forewings. The original description was made from Norwegian and French 

 examples together, but both are identical" (in litt., January 16th, 1900).
