Insects in the Virgin Islands, H. A, Baxlou {Agr. News [Barbados^, 15 

 (1916), No. 361, pp. 74, 75). — A brief account based upon a collection of insects 

 made by the curator of the experiment station in the Virgin Islands. 



Insect pests of plants, Northern Territory of Australia, G. F. Hill (Bui. 

 North. Ter., Aiist., No. 13 (1915), pp. 16). — A brief account is given of the more 

 important insect pests of plants in Northern Territory, Australia, including a 

 description of the life history, natural enemies, and methods of control of each. 



Insects infesting the cotton plant in Trinidad, P. W. Ueich (Bui. Dept. 

 Agr. Trinidad and Tobago, 15 (1916), No. 1, pp. IS, 19). — This paper briefly 

 considers eleven species of insects, their common names, natural enemies, 

 economic status, and control measures. 



Some insects of Solanura carolinense and their economic relations, M. P. 

 Somes (Jour. Econ. Ent., 9 (1916), No. 1, pp. 39-44)- — The author reports ob- 

 servations of the sudden development of the berytid bug Jalysus spinosus as a 

 serious pest of the tomato. Previous to this time /S. carolinense had served as 

 its food plant. It is stated that during the past two years this insect has worked 

 widely through Missouri and in some districts where tomato raising for can- 

 neries is of importance has occasioned serious loss. 



Sesia rileyana occurs in large numbers on S. carolinense. Boring into the 

 central part of the stem it worte downward to the roots, and passing down one 

 of the main branches at about the time it matures bores out of the root into the 

 soil. A test transfer of larvae from the horse nettle to tomato and potato 

 succeeded. 



A tortoise beetle (Cassida pallidula), a tingitid bug (Gargarphia solam), the 

 potato stalk borer, the fleabeetles Epitrix fuscula and E. cucumeris, the com- 

 mon sphingids PhlegetJiontius Carolina and P. quinquemaculata, and a lygseid 

 bug (Ischnodemus fallicv^), which attack cultivated crops, are reported as oc- 

 curring on S. carolinense.

 of citrus in Rhodesia and measures for their control.

 parasites, J. W. Cornwall (Indian Jour. Med. Research, 3 (1915), No. 1, pp. 

 116-131, pis. 6). — Accounts of the biology of the common silver fish of India
