mm. in length. He also tells us that the case of kroneella is 5-5 mm. 

 long, and has, at the end, three valves, which, however, are poorly 

 developed. I may add that, in hr<>neeUa, the fore-wing is broader, and 

 the costa is noticeably less straight, than in its ally. Fuchs recorded 

 wild pear as a proven food of Jcroneella, and he believed that some 

 cases found upon Sorhus aria were also referable to this species — 

 these, however, yielded no imagines. When introducing hroneella as 

 new to science, Fuchs stated that the only two certain localities for 

 the true trigeminella were Bornich and Kissingen, but the Walsingham 

 Collection contains four examples from Rachlau, in Saxony — these, 

 which were bred in June, 1901, from Sorhus aucuparia, were fon\^arded 

 by Prince Aristides de Caradja who had received them from Schiitze. 



My reasons for not having added G. trigeminella. to the British 

 List until now are as follows. In Stett. Ent. Zeit., 1881, p. 462, 

 Fuchs stated that the imago was so precisely similar to that of 

 hadiipennella that a description of it was needless, and as I had 

 for many years past, suspected that three species were confused 

 together under the name " hadiipennella, Dup.," it was obviously 

 desirable that this supposed confusion should be cleared up when 

 dealing with trigeminella. Owing to the recent arrival at the British 

 Museum (Nat. Hist.) of the Walsingham, Zeller, and O. Hofmann 

 Collections, and Duponchel's original drawings of Lepidoptera, it 

 has now been possible to attempt to investigate the matter. 



The three supposed species wliich seemed to require separation 

 were : — 



(1) BadiipenneUa, Dup. 



Duponchel's original drawing shows an ochreous Coleoplwra with 

 noticeable suggestions of some faint paler longitudinal lines on the 

 fore- wings. The piiblished figm-e (Sup. iv, PL 78, fig. 14), as is often 

 the case, agrees very badly with the original drawing, and shows the 

 fore-wings unicolourous deep ochreous, evenly speckled all over with 

 minute black dots. I made an independent note nine years ago that 

 the figure, except for the black dots, looks much like hitipennella. 

 Duponchel (Sup. iv, p. 346) says that he received the insect from 

 "M. Parreyss" {= Mann, ieste Zeller), under the name hadiipennella, 

 which his correspondent attributed to Fischer von Eoslerstamm. 

 Its foodplant was maple, upon which Mann found it commonly at 

 Vienna, and rarely at Leghorn, as we leam from Zeller in Lin. Ent., 

 iv, p. 402.
