formed. In each one of the well-formed pupa? (and in such skins of 

 others as are capable of examination), the wing, cases are fully de- 

 veloped externally, even to such a point that in all which I examined 

 for the purpose, six or more, I counted the eight veins of the wings 

 as ridges, and distinguished the fifth or intermediate vein as arising 

 from the discal nervure. Yet it was evident that there were no 

 wings under the cases in some, at least, because in them I could see 

 the sutures between the abdominal rings showing through the wing 

 cases. Five of the pupa? thus examined vary in length from 9 mm. 

 to 7 mm., and in breadth from 4 mm. to 3 mm., or from the largest to 

 the smallest of all the pupa? which I extracted. 



I carefully removed the dry and brittle pupa-skins from five of 

 these pupa?, under the microscope, and found no wings beneath 

 the cases. I opened the bodies of the five imagos extracted, and 

 found eggs in each, so there can be no doubt that these are females. 

 Harris' saying, therefore, if I understand it, is erroneous. 



I extracted three well-formed and undeveloped pupae from the jar 

 in which the larva? of the other description had been put, marked 

 No. 3058, and found besides some dead imagos in some of the 

 cocoons. All the imagos are wingless females, which are mainly, 

 almost uniformly, of one size, and on the average much smaller than 

 the imagos of 3057, but I see no characteristic difference between the 

 two. The wing cases of these are fully developed externally, like 

 those of No. 3057. Pupa? from 7 to 6 mm. long, from 4 to 2.5 mm. 

 broad. I made sure that these are females by the same tests as used 

 before. 



I have placed the emptied cocoons and the others, as well as the 

 extracted imagos, pupa?, and pupa-skins, in my collection, with name 

 and numbers corresponding, and will gladly verify my observations 

 by exhibiting the specimens. 



Mr. S. H. Scudder called the attention of the Section to 

 a Hesperian, in which ocelli were present. 



In a memoir published in 1831 by the Berlin Academy of Science, 

 King has reviewed the families of insects in which ocelli are present. 

 He states that they are wholly wanting in the rhopalocerous Lepidop- 

 tera, even in the Hesperians, and this assertion has been received up 

 to the present time. But in the male of the Papilio Accius of Smith- 

 Abbot a single ocellus is found in the middle of the front, consisting 

 of a slight eminence as broad as the base of the antenna?, smooth and
