points in the structure of the imago, such as the antennse, the 

 papillae of tlie tongue, the folding of the inner border of the 

 liind wing, the perfect development of the forelegs and the 

 presence of a fore-tibial epiphysis. The chrysalids of the 

 brush-footed butterflies are also shown to have passed 

 through the " succincti " stage by the persistence of a form 

 of abdomen then of use, but, in the " saspensi " stage, no 

 longer serving any purpose. Several features in other groups 

 of butterflies, such as the loss of the cremaster in the Lyctenids, 

 the procession of pupal characters in passing from the lower to 

 the higher groups, and similar details concerning the atrophy 

 of the foi'elegs and the structure of the tongue, are brought 

 forAvard for the first time or in a new connection. 



Passing now to partial histories and miscellaneous notes upon 

 habits, we have descriptions of the larv« and mines of various

 Van Wagenen ; the larva and pupa of Meganostoma eurydice 

 and Heterocamjja salicis, the former feeding on Amorpha, by 

 Mr. H. Edwards ; the larva and larval habits of Megathymus 

 yuccae by Mr. C. V. Riley ; the larva of Exyi'a rolandiana by

 We have notes on the oviposition and cocoon-making of

 Dr. J. Leidy, and notes by Dr. Anderson on the habits of 

 the trap-door spider of South Carolina, and my own on

 from Baron Osten Sacken and Mr. H. S. Treherne, gives us 

 an account of the habits of Termitina in Colorado, Nevada
