 Whether some of the species can "stand '' as such, we shall have to 

 leave to future discoveries for positive proof. My thanks are due to 

 Messrs. I. Doll, Hy. Edwards, Geo. Frank, Capt. Geddes and Dr. 

 H. A. Hagen for valuable information. I trust that Mr. Hulst will 

 take no umbrage at my remarks, as in the friendly contest for science, 

 both victor and vanquished gain.

BY H. J. ELWES. PRESTON, CIRENCESTER. 



Dr. Hagen's paper on Papilio Machaon and its allies has already 

 brought down on him severe criticism from Messrs. W. H: Edwards 

 and Butler, who are the leading representatives of a particular school 

 in Europe and America; and though Dr. Hagen can doubtless fight 

 his own battle in so good a cause, and defend himself without the help 

 of others, yet I should like to make a few remarks on the controversy. 

 Mr. Edwards seems to think just as Mr. Butler did when I ventured 

 some notes on the Genus Colias three years ago in the Transactions
