occasionally injurious to potatoes, but is seldom very destructive. The 

 habits of the larva are unknown. 

 [Now known as Macrobasis unicolor (Kirby).] 



Cocoons on Oats. (Country Gentleman, for July 8, 1875, xl, ft. 

 424, c. 2 — 7 cm.) 



The cocoons are of some parasite which has destroyed the larva in which 

 the eggs were deposited, as narrated. The species is not determinable 

 from the examples received. 



"Worm on Wheat. (Country Gentleman, for July 15, 1875, xl, p. 

 440, c. 2 — 9 cm.) 



The caterpillar is that of Leucania Harveyi, one of the Noctuid moths 

 which at times proves destructive to the heads of wheat in New York, 

 Pennsylvania, etc. 



[Now known as Leucania albilinea Hiibner.] 



Insects on Potatoes. (Country Gentleman, for July 22, 1875, xl, 

 p. 472, c. 2— S cm.) 



The insects, sent from Ashfield, Mass., as sucking the juices from potato 

 leaves, causing them to die, ai'e Lygus lineolaris, one of the Hemiptera. It 

 is almost or quite impossible to prevent their attack by external applications 

 to the leaves as they live only on the juices of the plant.

On Lycsena neglecta Edw. (Canadian Entomologist, vii, July, 

 1875, pp. 122, 123.) 



Reasons for differing from Mr. W. H. Edwards in his belief of the identity 

 of L. neglecta with L. Lucia, based on observations made at Center, N. Y. 



[Mr. Edwards has since shown (Papilio, iii, 1883, pp. 85-97) that neglecta 

 and Lucia are summer and winter forms of the polymorpliic Lyccena pseud- 

 argiolus Boisd.-Lec] 



On Orthosia ralla Gr.-Rob. (Canadian Entomologist, for Jul}", 



1875, vii, pp. 128, 129.) 



Orthosia ralla is not identical with O. ferruginoides, as has been stated : 

 the points of difference given. Synonymical dicta often at fault; tendency 

 to refer distinct species to " dimorphic forms" on insufficient grounds. 



Carpocapsa Deshaiziana in Seed-vessels of Euphorbia. Eead 



before the Albany Institute October 5, 1875. (The Argus 



[Albany, IST. Y.], for October 11, 1875. Proceedings of the 



Albany Institute, ii, 1878, pp. 264-267.) 



Jumping seeds exhibited, from the Alamas mountains in Sonora, contain 

 the larvae of Carpocapsa Deshaiziana, whose springing within the seeds 

 causes their jumps. Reference to writings on it by Lucas and Professor 

 Westwood, Three other species of jumping seeds noticed. The "jumps"
