A NEW SPECIES OF ADICELLA FROM SPAIN. 275 



Opinns is a name only, as Kirkaldy has previous stated in these 

 pages (Entom. 1900, p. 2-il). " Opinus is only mentioned in the 

 analytical tables." That it — Tapcimis is a matter of inference 

 only, and such names {Opinus has already caused confusion), in 

 my view, should be discarded. 



I am glad to see that Mr. Kirkaldy is still pursuing his 

 bibliographical investigations. 



A NEW SPECIES OP ADICELLA FKOM SPAIN. 

 By K. J. Morton, F.E.S. 



Apex of abdomen of male from side. 



Through the kindness of Dr. Chapman and Mr. Lucas, I 

 have been enabled to examine a number of Trichoptera, taken 

 by the former in North-western Spain during the past summer. 

 Amongst other interesting species there are two specimens of an 

 Adicella which has not been separated hitherto from Adicella 

 reducta, McLach., but which is certainly a good and distinct 

 species. The following notes will suffice for its identification : — 



Adicella meridionalis, n. sp. 



In general appearance and size much resembling A. reducta, but 

 differing much in the appendages of the male. 



The superior appendages similar to those of A. reducta, and the 

 median dorsal process also similar, but much shorter. The upper 

 penis-cover formed of two roof- shaped plates, the angles when viewed 

 from the side somewhat obtuse. Inferior appendages with a broad 

 basal part, the apical part being blade-shaped, and apparently narrower 

 in its proximal portion. The penis-sheaths forked, the branches 

 lanceolate, the upper branch long and projecting, the lower shorter and 

 not always visible. The last ventral segment with a prominent pro- 

 cess, broad at the base and gradually tapering. 



Two males; Casayo, July 2nd-8th, 1906 (Chapman).
