176 REPORT ON NATIONAL MUSEUM. 



EiLEY, Charles V. — Continued. 



River flats hj AhUa argillacea in 1882, owing to the belateinent of tho crop by 

 floods; want of suitable machines for destroying these insects; describes the 

 machines for this purpose invented during the investigations of the U. S. En- 

 tomological Commission ; mentions poisons available for use ; states advan- 

 tages of early application of poisons, and describes methods for the prepara- 

 tion and application of these poisons. 



Habits of Cyhocephalus. 



(Amer. Nat., June, 1882, xvi, p. 514. ) 



Cyhocephalus nigritulas feeds on the scale-iusect Chionaspis pinifolice, on 

 Finns eUiottii in South Carolina, and C. ealiformcus on a Coccid on apple trees 

 in California. 



The triunguliu of Meloidce. 



(Amer. Nat., June, 1882, xvi, p. 515.) 



J. Lichtenstein states that the trinngulin of Melee proscarahceus was de- 

 scribed in J. L. Frisch's " Beschreibung von allerley Insecten in Teutschland," 

 1727, VI, p. 15 ; all knowledge of it, however, was afterward lost. 



— Hibernation of the army worm. 



(Amer. Nat., June, 1882, xvi, p. 516.) 



Gives confirmation of author's views, as revised in 1880, in regard to the 

 hibernation of ieitcania wnipwncte ; mentions preferred localities for oviposi- 

 tion ; states prospects of extensive injury by these insects in the more north- 

 ern States in 1882. 



The utilization of ants in horticulture. 



(Nature, 8 June, 1882.) 



Abstract of C. J. Macgowan's "Utilization of ants as insect destroyers" in 

 China (North China Herald, 4 April, 1882); capture and sale of two species 

 of ants which build nests in trees, and colonization of these ants in orange 

 orchards to destroy the insects injurious to those trees. 



Repelling insects by malodorants. 



(Amer. Nat., July, 1882, XVI, p. 596. ) 



This is a critical review of J. A. Lintner's " A new principle in protection 



from insect attack " (Proc. Western N. Y. Hort. Soc. for 1882, v. p. ) ; 



states that odorous substances repel insects more by their toxic properties 

 than by their odor; mentions failure of attempts by the use of strongly 

 smelling substances to prevent oviposition, and shows that the senses of sight, 

 touch, and taste are generally more important in the insect economy than the 

 sense of smell. 



Habits of Cosdnoptera dominicana. 



(Amer. Nat., July, 1882, xvi, p. 598. ) 



Ajinounces discovery by F. H. King that Coscinoptera domiiiicana is inguili- 

 nous in ants' nests in its earlier states; occurrenceof similar habitsin related 

 species. 



Change of habit; two new enemies of the egg-plant. 



(Amer. Nat., Aug., 1882, xvi, p. 678-679.) 



Describes sudden acquisition by Horyphora juncta and by Cassida texana of 

 the habit of feeding on Solanum vielongena, these species having been found 

 previously on S. caroUnense and S. elwagnifoUum, respectively; occurrence 

 of C. texana on <S. caroUnense ; geographical distribution of these two insects.
