OCCUEEENCE IN ENGLAND OF PABORNIX FINITIMELLA Z., 

 A SPECIES OF GRACILARIADAE NEW TO THE BEITISH LIST. 



BY F. N. PIERCE, F.E.S. 



Pakornix Spuler, 1910 = Ornix Tr., 1833 = Oniix Zeller, 1839 

 —finitimella Zeller, Stett. Ent. Zeit., 1850. 162. 



Parornix finitimella Zeller. 



Genitalia. S • Valva pedunculate, the base being greatly extended, 

 rounded above, pointed below, and narrowing before expanding into a somewhat 

 ovate valva, sharply pointed ventrally ; sacculus broad, quickly tapering to a 

 point, free. Uncus not produced, the soft upper tegumen bearing in its place 

 two or three hairs. Aedoeagus sigmoid, pointed at its apex. Saccus produced 

 from two emarginations of the lower tegumen. Eighth segment produced 

 ventrally in a long rounded flap, which in situ covers the internal part of the 

 genitalia. 



? . Ovipositor not lobed, clothed with short spines. The rods of both 

 eighth and ninth segments very short. Ostium without thickened ductus bursae, 

 protected at either side by a stout projecting plate. Ductus biirsae weak, long, 

 ornamented with rounded spots before reaching the bursa. Bvu'sa with two 

 scobinate signa at its junction with the ductus. 



Type : ,^ , Zeller Coll., Mus. Wlsm., in British Museum ; taken at 

 Glogau, July 25tli, 1842.

This species has been found in collections mixed in series of 

 P. anglicella and P. torquilella. Through the kindness of Mr. J. 

 Hartley Durrant I have been allowed to examine the genitalia of the 

 series in the Zeller collection. This consists of six specimens, com- 

 prising three species : — 



1. (J — finitimella Type. 4. $ — avellanella. 



2. $ — sp. ("(*) new to me, probably 5. $ — sp. (?). 



a known Continental species. 6. ? — probably $ of finitimella. 



3. (?— do. 



There is no mistaking the type, as it is carefully labelled with the 

 exact date and locality referred to by Zeller. 



Stainton, in his "Natural History of the Tineina," Vol. VIII, 

 1864, p. 296, in speaking of F. anglicella 52 years ago, says " perhaps 

 these specimens bred from sloe, should be referred to finitimella."
