accuracy, say by the thousand, and keep from forty to fifly 

 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 a rare plant, where it was abundant, imsuccess- 

 fuily ! Where, on his own rule, is the " positive, ocular 

 DEMONSTRATIVE PROOF " that he was ever there at all ? He 

 has ray word for what I said, — he does not believe me ; I 

 have his word, — am I to believe him f But I am 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 IVickham. — T took a 

 single specimen of E. unifasciata at light, at West Wickham, 

 on the 14th 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 lately by Mr. Marshall 

 (Entom. vii. 209) from Cheltenham. — W. A. Forbes; 35,

Nonagria brevilinea, Phycis Davisellus, and Grapholita 

 grandcevana. — A short time since I forwarded specimens of 

 Nonagria brevilinea, Fenn, Phycis Davisellus, Newman, and 

 the supposed Grapholita grandaevana of Zeller, to my friend 

 Dr. Staudinger, and have received his remarks upon them. 

 He says: — " Notiagria 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, Duj)onchel (vol. x. fig. 278). Herrich- 

 Schseffer 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 1 reared a single specimen in 

 Andalusia from 13 lex, 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
