This is a good place to call the attention of readers to the fact that 

 No. 3 of this Journal will be sent only to those who have sent in their 

 subscription before that number is issued. We are sorry to make such 

 a provision, but we have not yet been able to find a printer sufficiently 

 interested in the advancement of Entomology to print our paper for less 

 than regular price in "Hard Cash'.

Mr. Hulst called the attention of the members to a collection of Coenonymph(P, 

 bi'ought by Mr. Geo. Frank. He said that these specimens added considerable 

 positive knowledge on the subject of the variation of the species. These speci- 

 mens, undoubtedly C. ochracea Edw., varied in color of the upper surface of the 

 wings from a dark brown to a very light buff, the males being darker than the 

 females. There was also a variation in both sexes, some having ocelli, others 

 wanting them. Beneath, there was jirst as wide variation in the ground color, 

 and in the ocelli. The broken white band on the secondaries was aboiit or quite 

 obsolete in some, in others broad and definite. One specimen had a decidedly 

 reddish brown submarginal band on the hind wings beneath. 



The qvrestion was asked, "might it not be that these were sejDarate species 

 flying together"? 



Mr. Frank said they were taken near St. Paul, Minn. Mostly on the same 

 day in one small locality; that there was a continuous intergradation and that 

 he found some widely differing in markings and color, in coitu. 



Mr. Hulst spoke at some length upon the subject of the evening "the effect 

 of external conditions upon Lepidoptera", remarking upon the three influences, 

 temperature, humidity, and food, and took the ground that the most of direct 

 and immediate changes in the appearance of the insect, resulting from these 

 three causes, could be explained on the theory of impaired or redundant vitality. 

 And in the most of cases where the changes did not apparently follow from im- 

 paired or redundant vitality, it was only fair, though our knowledge did not give 

 proof, to suppose these were the operating causes. Considerable exception was 

 taken to Mr. Hulst's views, but as the hour of adjournment had arrived, nothing 

 but an ex2<ression of dissent could be given. It was especially thought by some, 

 that food had often a direct modifying infli;ence.
