collected in a hole on the inferior side of the stone, about one foot below 

 •the surface of the water. When I turned the rock they floated on the 

 surface of the sea. A good many of these specimens were young and not 

 full grown. 



Hoping these facts will be of some interest for you, 

 I have the honour to be. 



Yours very respectfully,

NOTES ON THE NEURATION AND RELATIONSHIPS OF 

 PIERIDI AND ANTHOCHARIDI. 



BY J. W. TUTT, F. E. S., LONDON, ENGLAND. 



(Editor of the Entomologists Record, Etc). 



I little thought when I wrote my short note {ante, pp. 47-48) that the 

 American species of Anthocharidi were in such a muddle as Mr. Dyar 

 has quickly proved them to be. It will be very necessary to go much 

 further now with the question, and I would suggest that those who have 

 the opportunity should, during this season if possible, and next season if 

 it be now too late, examine critically and make drawings of the eggs, larvge 

 and pupai of the Anthocharids in question and publish them in the Can- 

 adian Entomologist, where they can be examined by British workers and 

 compared with European species. Evidently, as the American species in 

 question are widely distributed, it will want a number of willing hands. 



It must be very evident to all scientific lepidopterists that however 

 excellent a means of subdivision the neuration may present, yet it is only 

 one character of a great many that have to be considered. The neuration 

 I consider gives us a. prima facie reason for certain groupings, and I have 

 but little doubt that the other stages of the insects' life will in the main 

 substantiate the primary groups thus obtained. 



The American species of the genus Pieris seem to be very homo- 

 geneous and the genus fairly defined ; it will have to be left to .American 

 specialists to determine the position of Nathalis iole. (The true mem. 

 bers of Pieris have six subsegments in the larva). 



The species creusa, sara, julia, Morrisoni and stella would appear 

 to belong to ^7/^// /<?<•, /. e., they have the neuration {Ante, p. 47. fig. 3.) of 

 that genus.
