58 Mr. Kenneth J. Morton on 



and 12th June, 1865, McLachlan) ; River Yealm at Corn- 

 wood, Devon, 16th May; and Yorkshire (Dunford Bridge, 

 18th June). It is the species recorded from Rannoch in 

 Ent. Mon. Mag., voh xxvii., p. 47, as T. trifasciata (King 

 and Morton), and I have found it in May and June in 

 almost every hilly district in Scotland which I have 

 visited. 



Tfeiiiopteryx trifasciata, P., is no doubt equally wide- 

 spread, but in this country, and probably elsewhere, it 

 occurs very early in the season, and is therefore perhaps 

 less noticed. In Scotland it is very common in the Clyde 

 district in March, and Mr, King and I found it rather 

 plentiful at Rannoch in the first half of April last (1895). 

 The only British S in Mr. McLachlan's collection is from 

 the last-named locality (the late Dr. Buchanan White), 

 but the species is well represented from the Continent : 

 Meseritz, Posen, Prussia (Zeller, 29th April, 1849 ; one 

 of the examples named by Brauer) ; Switzerland (Burg- 

 dorf, April, Meyer-Diir) ; Silesia ? (presumably from 

 Silesia, as the label is in Schneider's handwriting) ; 

 Turin (15th and 16th March, Ghiliani). In my own 

 collection are examples from Bohemia and Switzerland 

 (Klapalek and Ris, respectively), all taken in March. All 

 the British 6 examples of T. trifasciata seen by me have 

 the wings much aljbreviated (expanse 13 to 15 mm.), 

 whereas Continental $'s have usually well developed 

 wings (23 mm.) although there are evidently exceptions, 

 one from Turin being short-winged.

part) 



Head and thoracic segments in the dry insect shining blackish. 

 Antennae blackish, legs and seta) fuscous. Wings sub-hyaline with 

 fuscous neuration. In the forewings the basal end of the lower 

 intercubital cellule is usually acute, or at least much narrowed, and 

 the anterior margin of the upper intercubital cellule is slightly 

 curved. Joints of sette short. In the ^ the large side pieces of 

 the genital apparatus are broad at the base, upturned, and sub- 

 acute at the apex, which when seen from above is barbed ; seen 

 from the side there is usually visible beneath or within these pieces
