accuracy, say by the thousand, and keep from forty to fifty 
as our series in our cabinets,—are not to know a species 
when we see it, but are to send “ positive, ocular demonstrative 
proof” to people who commenced a study where we almost 
left off. Grant this claim, and by a parity of reasoning 
I must have “positive, ocular demonstrative proof” that 
Mr. Crewe went out in the carriage of his friend, and beat 
half a mile of arare plant, where it was abundant, unsuccess- 
fully! Where, on his own rule, is the “ POSITIVE, OCULAR 
DEMONSTRATIVE PROOF” that he was ever there at all? He 
has my word for what I said,—he does not believe me; I 
have his word,—am I to believe him? But Iam no logician. 
Mr. Crewe may, however, sit on which horn he likes,—only 
on to one he must go; or there is an end to all papers on 
Natural History,—and so ends our “ feeling disputation.” —

Emmelesia unifasciata at West Wickham.—I took a 
single specimen of E. unifasciata at light, at West Wickham, 
on the ]l4th of August last (1874). This is, I believe, a new 
locality for this scarce species, though it has been before 
recorded from Forest Hill, and Jately by Mr. Marshall 
(Entom. vil. 209) from Cheltenham.—W. A. Forbes; 35,

Nonagria brevilinea, Phycis Davisellus, and Grapholita 
grandevana.—A short time since I forwarded specimens of 
Nonagria brevilinea, Fenn, Phycis Davisellus, Newman, and 
the supposed Grapholita grandzvana of Zeller, to my friend 
Dr. Staudinger, and have received his remarks upon them. 
He says:— Nonagria brevilinea, Fenn.—I never saw it 
before; it is a very good species, very distinct from all others 
known. Phycis Davisellus, Newman.—This species has now 
been described four times: it is, without any doubt, Ne- 
phopteryx genistella, Duponchel (vol. x. fig. 278). Herrich- 
Scheffer was the second who described and figured it under 
the name of Ulicella (Pyr. fig. 149), from two males, found 
by the late Julius Lederer in Andalusia: the originals are 
now in my collection. Then I reared a single specimen in 
Andalusia from Ulex, and, as at that time I did not know 
much about the Micro-Lepidoptera, I sent it to Professor 
Zeller, who said that it might be a new species; so I described
