their eyes were then covered with a thick coating of india-ink, 

 and in this condition they were set free or placed near sweets, 

 or with their mates. From these experiments he concludes 

 that the sense localized in the antennte cannot be regarded as 

 simply that of touch, of hearing or of taste, nor can it be re- 

 garded as uniting the complex functions of these senses ; he 

 would rather regard it as a sense of direction or orientation. 



The observations of Mr. Trouvelot led Dr. Packard to make 

 somewhat similar experiments, especially upon Hymenoptera 

 and Lepidoptera ; but they were not sufficiently extended for 

 him to draw any general conclusions, and were in some in- 

 stances so contradictory as to need repetition ; but it would 

 appear that the nervous centres are permanently affected by 

 deantennization. 



Dr. J. G. Morris has observed, what Charpentier recorded 

 many years ago, the action by which an earwig opens its teg- 

 mina by means of its forceps before flight. 



Concerning unusual and unexpected variations of form, we 

 have an exquisite colored plate of Papilio calverleyi, and figures 

 of hermaphroditic specimens of Papilio asterias and P. turnus 

 by Mr. W. H. Edwards. Mr. Edwards also announces that he 

 has raised Lime^iitis arthemis fi'om eggs of X. proserpma. Mr. H. 

 Edwards describes an apparent dimorphism, possibly phytopha- 

 gic, in the larva of Halesidota agassizii. Mr. C. G. Siewers de- 

 scribes some curious variations said to occur in Arctia isabella, 

 and Mr. W. V. Andrews describes the variations of Bryocmnpa 

 ruhicimda. Mr. C. E. Worthington reports finding two pu])ae 

 of Platysaniia ceeropia in one cocoon, and Mr. W. H. 

 Edwards gives us a continuation of his experiments upon 

 the effect of cold in changing the form of certain butterflies. 

 His experiments were made upon Phyciodes tharos, Papilio 

 ajax and Lycaena pseudargiohis. These species were selected 

 because they have a spring form differing from the forms ap- 

 pearing later in the season. Chrysalids were placed in an ice- 

 box, to simulate the conditions of the winter season ; but the 

 experiments lost a part of their value, because he was obliged, 

 at times, to leave them in the care of others. The result, 

 however, proved the possibility of producing in all three
