N. suh-himaculella.—I have taken this species on the trunks of oak-trees in 

 Askham bog's, near York. 



N. salicis. — Larva yellowish-green, making blotch-like mines in the sallow. 

 Cocoon rather large ; brown, with the broad end yellowish. 



N. flos-lactella. — The larva of this species is yellow ; it is very gregarious, and 

 occurs in nut-bushes. I have seen one leaf containing twelve of the larvae. Cocoon 

 white, of a rather sickly appearance. 



N. ignobilella. — This insect is scarce, and is found in whitethorn. The rich 

 yellow larvae make blotches in the leaves, very much like those oi pygmceella. This 

 species was authenticated for me by Mr. Stainton. 



N. cmgulifasciella. — This species frequents the wild rose, and is very gregarious 

 in its habits ; I have found one bush quite infested with it. The larvae, which are 

 of a greenish hue, form at first dark contorted tracks of excrement, which terminate 

 in large blotches. Cocoon nearly black. This species was authenticated by Mr. 

 Wilkinson, of Scarborough. 



N. atricollis. — This insect is found in whitethorn. Larvae greenish white, 

 forming a dark track of excrement. Cocoon black. 



N. malella. — Very plentiful in wild apple. Larvae bright orange. Cocoon 

 yellow. 



A'', gratiosella. — This species breeds in whitethorn. Larvae yellow, making 

 small blotches. Cocoon pinkish-white. 



N. 7narginicolella. — Scarce ; found in elm. Larvae yellowish, making long 

 galleries at the edge of the leaf. Cocoon green. 



A'^. aurella. — Plentiful in bramble. Larvae yellow. Cocoon whitish-green, with 

 a flat angulated margin. 



I now possess the above species, which were quite unknown to me before 

 the publication of Mr. Stainton's Manual. — R. Hind, 25, Gillygate, York, 19th 

 November, 1864. 



NOTES ON COLLECTING, MANAGEMENT, &c., (LEPIDOPTSBA). 



BY H. G. KNAGGS, M.D. 



THE CATERPILLAR STATE. 



COLLECTING (Continued from page 195.) 



Fruits, seeds, &c., which fall before they have ripened, unless the weather 

 be very tempestuous, generally contain some larva, frequently of the family 

 Tortricina, as Cftrpocoypsa pomonana (apples) ; C. funehrana (plums and sloes) ; 

 C. grossana, (beech masts) ; C. splendana and Juliana (acorns). These should be 

 collected at the time of falling as quickly as possible, for the larvae soon quit the 

 fruit to spin up elsewhere. Other seeds, flower-heads, &c., even though presenting 

 no outward. sign, are so apt to contain larvae, that the simple fact of their presence 

 may be looked on as an indication of the probable inhabitants, as A. gentiana.na, 

 in the pith of teasel heads ; Eup. roseana, in the seeds of the same ; D. pisanaand 

 nehritana, in pea-pods, and many others. All that is necessary is to collect the 

 catkins, fruits, seeds, and pods, and place them in a suitable breeding cage, such as a 

 common scaleboard hat-box, into the lid of which a piece of muslin haa been in- 

 serted for ventilating purposes.
