NOTES ON LIMENITIS PR0SP:RPINA AND ARTHEMIS. 



BY W. H. EDWARDS, COALI5URGH, W. VA. 



Last fall I obtained a few eggs from a female Z. proserpma, in Sept., 

 while in the Catskills, and raised eight larvge to hybernation, which took 

 place after third moult. This spring I have carried four of these 

 to maturity with the following results : The first chrysalis 

 gave butterfly this morning (April 29th), a male arthemis. For some 

 hours before the emergence the white band of arthemis was distinctly 

 seen through the wing case. The second was but a few hours younger 

 and during this afternoon has given proserpi7ia male. I expected this, as 

 here there was no white band on the wing case. The third and fourth 

 produced arthemis, making three arthemis and one proserpina. 



After liybernation the fourth and fifth moults took place. As disippus 

 undergoes five moults in same way, I presume ursula will be found to, and 

 that it is the rule for this genus, in this country at least. We know that 

 proserpina is found flying with arthemis in the White Mountains and 

 Catskills, and probably in the Adirondacks. But I have never seen it from 

 Canada, though arthemis roams over British America from Nova Scotia to 

 low down Mackenzie's River. Can you or can any of your readers tell 

 me whether this form (pioserpina) has been taken in Canada, or British 

 America, and where, if at all ? I wish to get the northern limits of the 

 form, preparatory to illustrating the species in Butterflies N. A. I should 

 be glad to receive letters on this matter from any one who can give the 

 information I seek. 



A NEW GENUS AND SPECIES OF GEOMETRY. 



BY A. R. GROTE, BUFFALO, N. Y, 



Meskea Grote (n. g.) 



This genus of Geometrce resembles Tornos ; tlie fore wings are larger 

 and with the apices more produced ; the external margin is longer and 

 more oblique. The hind wings are narrow and lanceolate, with the apices 

 pointed and a little depressed ; external margin straight or a little incurved. 

 The female abdomen is like that of loriios, and is thickly tufted at the
