been obtained previously. I bave boxed large numbers both of this and of 

 Pylades but invariably without result. I trust that others will be induced 

 to try Air. Edward's simple plan by which we may very greatly increase our 

 knowledge of the earlier stages of butterflies. — Samuel H. Scudder, Cairo,

Nova Scotian Lepidoptera. — At a Meeting of the Institute of Natural 

 Science, Halifax N.S., on Nov. 14th, the President, J. M. Jones, Esq., read 

 a paper "On the Diurnal Lepidoptera of Nova Scotia, Iihopalocera, Part 1." 

 The following species were common in the province, Papillo turnus Linn.; 

 Pieris oleracea Harris, P. rapce Boisd., Colias pJiilodice Godt., ArgynnU 

 aphrodite Fabr., Argynnis myrina Cram., Melitaea tharos Cram., Grapta C. 

 argentcum Kirby, Vanessa antiopa Linn., Pyramids cardui Linn., P. Hunter a 

 Smith, Xymphalis artkemis Drury, Erebia nephele Kirby, Satyrus alope 

 Fabr. ; while Danais archippus Fabr., Melitcsa ismeria Boisd., Grapta 

 inter rog at ionis Godt., (7. comma Harris, Vanessa J. album Boisd., V. milberti 

 Godt., Pyrameis atalanta Linn., Nympkalis dissipus Godt., Dehis Portland ia 

 Fabr., were rare. The author dwelt upon the introduction of Pieris rapce 

 into this part of the Canadian dominion within the last few years, and 

 alluded to its abundance last summer in the neighbourhood of Halifax, where 

 it did an immense amount of damage to the'cauliflower crop3. He mentioned 

 the probable benefit that would arise from the introduction of the house 

 sparrow of England {Pyrgita domestical) that great enemy of caterpillar 

 life, which would amply repay the trouble and expense of importation. At 

 the present time the caterpillars were almost free from molestation, and it 

 was but proper, when possible, on the introduction of an insect pest, to 

 introduce also its known enemy. The author had observed that even in so 

 small a country as Nova Scotia many species of butterflies were quite local 

 in distribution, and species quite common on one side of the province were 

 altogether unknown on the other, although the distance between such positions 

 was not more than thirty miles. Several Hesperians were yet unnamed, and 

 these when identified with some Lycaenians, would be included in Part 2. —
