You have already heard from our Secretary-Treasurer's Report the 

 satisfactory condition of our finances and other business matters ; I need 

 not therefore trespass further upon your patience and attention. Heartily 

 thanking you, gentlemen, for your kindness towards myself and my 

 colleagues during our term of office, and for the honour which you have 

 conferred upon me by calling me to preside over you, 



I have the honour to remain, with best wishes for the advancement 

 and prosperity of the Society, 



Your humble and obedient servant,

ON THE IDENTITY OF GRAPTA DRYAS WITH COMMA. 



BY W. H. EDWARDS, COALBURGH, W. VA. 



On the 30th of July Mr. T. L. Mead, at Coalburgh, took two females of 

 Grapta Dryas and tied them in a muslin bag to a branch of Hop-vine. 

 The result was a large number of eggs, laid on the leaves and in the 

 bag. On the 5th the eggs were all hatched. The larvae we carried 

 through safely, and on the 21st the first ones began to change to chry- 

 salids. In course of the next three days all were changed, upwards of 

 sixty. Towards maturity some of the larvae were white, as represented in 

 the plate of Dryas, in the " Butterflies of North America." The others 

 were black, like the larvae represented in plate of Comma in the same 

 volume. On the 30th the imagines began to appear, and nearly all are 

 true Comma; but six are Dryas, two $ and four <j> . The relation of 

 the two forms to each other is therefore similar to that of the two forms 

 of Interrogationis. The name of the species should be G. comma, Harris, 

 and the one form the type figured in my plate as comma, should be called 

 comma var. Harisii, and the other comma var. dryas, the two being equal 

 varieties of one species and not one a variety of the other.
