THE CANADIAN ENTOMOLOGIST. 143 



The best, and indeed the only feasible remedy for the ravages of this 

 insect is to cut off and burn, or carefully tread under foot, the whole 

 portion of a branch that is covered with the web. As the worms feed 

 always beneath their web, and do not wander over the tree like the Tent 

 Caterpillars, this method of dealing with them is a sure one. Where it is 

 unadvisable to cut off the branch, as may sometimes be the case with 

 young or dwarf fruit trees, the insect may be got rid of by simply drawing 

 the infested leaves through the hand and crushing the caterpillars upon 

 them.

6. Danais, Latr. — It is objected that our species is generally known 

 as a?'chippns, to the restitution of the name plexippus, given by Linn, to 

 our common species. It is much better to alter a label than to perpetuate 

 an error. 



7. Basilarclia, Scudd. — Together with sixty-eight specimens of 

 arthemis, Mr. Chas. Linden took six proserpina near Buffalo, N. Y. The 

 material before me makes me feel sure that Mr. Scudder is wrong in 

 referring Edwards' species as a synonym of tirsula. Traces of the white 

 band and the general size make me suggest that we have possibly to do 

 with a race of arthemis. But as yet we must catalogue proserpina as 

 distinct. We have a reasonable excuse for preferring ursula as the trivial 

 name for our common species. To this genus we must refer L. weidemey- 

 erii. 



8. Dox-ocopa, Hubn. — It is not disputed, or at least should not be, 

 that we have no true Apatura known from the Atlantic district. 



9. Grapta, Kirby. — The retention of Kirby's term is defensible on 

 general grounds. 



10. Nymphalis, Latr. 11. Papilio, Linn., restr. Scudd. — Schrank's 

 limitation of the term originally used for all the butterflies by Linn, is 

 referred to by Latreille, Insecta Pterodicera, p. 198, where vanessa is
