Schiner to Limnohia pilipennis, Egger, but tlie apical part of the 

 wing is not distinctly hairy, and the apex of Sc 1 (end of the aux- 

 iliary vein) is placed almost above the base of Rs (second long vein), 

 and not beyond it as in Egger's species. It was with interest, therefore, 

 that I noticed Lundstrom's record (Acta Soc. Fauna et Flora Fennica, 

 29, JSTo. 8, 1907) of a Dicranomyia from Finland as doubtful 

 pilipennis. It was evident from Lundstrom's remarks that his speci- 

 mens belonged to the same species as my insect, as the latter agreed 

 with all the characters in which Lundstrom's species differed from 

 'pili/pennis. In the recently published Part VIII of his valualile 

 "Beitr. zur Keunt. der Dipt. Finlands " (op. cit. 36, No. 1, 1912) 

 Lundstrom corrects his former record and identifies his insect with 

 Strobl's short description of Dicranomyia morio var. rnfiventris, 

 stating, however, that it is not a variety, but a perfectly good species, 

 quite distinct from morio. My specimen agrees with all that Lund- 

 strom says, and a caustic potash preparation of the hypopygium 

 accords with his Fig. 46 (Part VIII, Taf. 3). I take D. morio in this 

 part of Pei'thshire, but so far have not come across rnfiventris. 



2. ACYPHONA AREOLATA, Siebko. 



This is another interesting fly which had long baffled all my 

 attempts at identification, and it was only recently while studying 

 Wahlgren's important paper on Zetterstedt's types of Nemocera (Arkiv 

 f. Zool., Bd. 2, No. 7) that I found the clue to what it is. A refer- 

 ence to "Insectorum Norvegicorum," Fasc. IV (1877), led me to con- 

 sult that work, and I have no doubt that my insect is Siebke's Erioptera 

 areolata. It answers very well to the description given, but I can see 

 very little sign of the darkening of the tips of the femora or tibise. 

 The whole insect is pale brownish yellow, darkened above on thorax 

 and abdomen ; the latter having the hind margins of the segments 

 and the hypopygium yellow. The very small discal cell, " subcuneate" 

 in form, is a characteristic feature. 



The straight anal vein (A 2) places this species in Osten Sacken's 

 genus Acyphona, as Wahlgren points out, and our List will now con- 

 tain two species in that genus. 



I have one specimen only, a male caught at Musselburgh, Mid- 

 lothian, on July 30th, 1906. The species is recorded by Lundstrom 

 from two districts in Finland.
