Williston give their experience in liunting Amblychila, show- 

 ing that it has subterranean and crepuscular habits, and 

 noticing briefly the eggs and larva. Mr. W. H. Dall gives lis 

 an entertaining account of the movements of " educated" fleas, 

 which he shows to be simply due to their struggles to escape 

 when tied together, a ludicrous parody on education. Mr. 

 C. V. Riley defends his theory of the pollination of Yucca by 

 Pronuba, from the criticisms it has called forth, and Mr. H. 

 Edwards gives some interesting notes on the larva3 of Psychidae 

 which construct curious nests of various vegetable fragments, 

 within which they live and undergo their transformations. He 

 mentions three new forms of these nests from California. Mr. 

 Wm. Edwards describes a flight of butterflies, probably of 

 Danaida pJexippns, near Natick, Mass. 



Concerning the food of insi.'cts and insects as food, we have 

 notes on the plants which nourish Ilemileuca ynaia, by Messrs. 

 R. Bunker and O. S. "VVestcott, and Saturnia ^o, by Mr. L. W. 

 Goodell, besides the scattered notices which usually accompany 

 general lists. Mr. C. R. Dodge gives a curious account of the 

 perforation of a minie ball, which had lodged in a tree, by the 

 larva of a borer, and Dr. H. A. Hagen supplements the account 

 by a long list of lead-boring insects. Dr. A. S. Packard, Jr., 

 notices the preference that white butterflies show for white 

 flowers, and Mr. T. G. Gentry, in his Birds of Eastern Penn- 

 sylvania, gives a long list of insects which serve each bird as 

 food, showing on his part remarkable industry, and demanding, 

 on our side, a certain amount of credence. 



With regard to the seasons of insects, Mr. F. B. Caulfield 

 publishes some facts to show that Meloe angusticolUs is a spring, 

 and M. amei'icanus, an autumn species, which Mr. W. Brodie's 

 observations do not confirm, if he has rightly determined his 

 species. Mr. F. B. Caulfield believes that Vanessa J-album 

 does not appear later than other Praefecti ; and I have attempted 

 to illustrate the harmony of tints in nature by showing how 

 closely, in New England, the colors of the prevailing butter- 

 flies, at any one season, correspond to the hues of the land- 

 scape.
