P. MARGINELLUS and P. SUTtTRALIS. 



Mr. Newbery has called my attention to the fact that in some 

 specimens of /-•. rvturalis there is a darkening of some parts of the 

 maxillary palp, and as the species is usually distinguished in literature 

 by describing the palp as entirely yellow, this darkening may give rise 

 to doubts as to the validity of the species. It is desirable therefore to 

 point out that it is the colour of the extreme tip of the palpus that is 

 to be taken into account, and that this is invariably black in niarginelhts 

 and pale in sufuralis. Besides this the two are so distinct in other 

 respects that confusion should not be possible. As regards the 

 aedeagus : in P. marcjlnellns it is remarkable by the great elongation 

 of the dorsal blade of the median lobe at the tip, while in suturalis 

 this part is quite short. 



P. suturalis is considered to be the same as coardatus G-redl. I am 

 unacquainted with Grredler's description, but if the translation by 

 de Marseul (Abeille, 8, p. 112) be correct, the tip of the palp is dark 

 in coardatus. 



EXPLANATION OF FIGURES. 



This is a diagram of the male genitalia of Philydrus based on P. maritimus, 

 the structure of whicli it represents fairly well. 



A. — Dorsal aspect, the lateral lobes being dissevered at their base, and 

 forced somewhat apart so as to display the median lobe. 



p.d.- — penultimate dorsal sclerite ; enc— encasement^last body segment; 

 b.p. — basal plate made to appear rather too broad owing to section of the tube 

 at the bases of the lateral lobes ; 1.1. - lateral lobes ; d.b. — dorsal blade of the 

 median lobe ; v.- root of median lobe ; v.b. — ventral blade of the median lobe ; 

 c.p. — cross-piece of the median lobe at the orifice of the duct. 



B.— Ventral aspect of the median lobe ; lettering as above.

DESCRIPTIONS OF TWO FURTHER ADDITIONS TO THE 

 BRITISH TOBTRICINA. 



BY F. N. PIERCE, F.E.S., AND THE REV. J. W. METCALFE, F.E.S. 



In working through the genitalia of the British Tortricina, a 

 specimen was examined which was supposed to represent the spring 

 brood of Peronea ferrugana. This proved to be not only distinct from
