Some Florida scale insects, C. E. Wilson {Quart. Bui. Plant Bd. Fla., 2 

 (1917), No. 1, pp. 2-65, figs. 70). — Brief descriptions are here given of 86 

 species of C5occidae found in Florida, together with their host plants and dis-

Ocneria dispar in Britain, R. Adkin (Proc. So. London Ent. and Nat. Hist. 

 Soc, 1916-17, pp. i-6).— This paper reviews the history of the occurrence of the 

 gipsy moth in Great Britain, where It has been introduced several times. In 

 some unknown way its extinction has resulted, and it is significant that this 

 and another species (Chrysophanus dispar) have disappeared from the fen dis-

 of one another. 



The life history of the okra or mallow caterpillar (Cosmophila erosa), 

 H. L. DoziEK (Jour. Econ. Ent., 10 (1917), No. 6, pp. 5S6-542, pis. 2).— This is 

 a report of biological studies at Gainesville, Fla., of C. erosa, an account of 

 which pest by Chittenden under the name Abutilon moth has been previously 

 noted (E. S. R., 30, p. 157). 



It is said to be a source of serious damage to okra, and to injure the cotton 

 rose (Hibiscus mutabilis) and the flowering maple (Abutilon striatum) at 

 Gainesville through attacking the leaves. Thirty-four days were found to be 

 required for the completion of its life cycle. 



The pink bollworm in Brazil, E. C. Green (Bol. Agr. [Sao Paulo], 18. ser.,

 author reports the thorough infestation of chocolate-coated marshmallow candy 

 by the larvae of P. interpunctella at San Francisco, Cal. The pest requires 40 

 days at a temperature of from 23 to 26' C. (73.4 to 78.8° F.) to complete its life 

 history. 



A demonstration in mosquito control, 0. W. Howard (Jour. Econ. Ent., 10 

 (1917), No. 6, pp. 517-521). — This is a report upon a successful antimosquito 

 campaign conducted at Minneapolis, Minn.

 Med. Research, 5 (1917), No. 1, pp. 192-19^, pi. 1). — A parasite found in Ano- 

 pheles funestus listoni, A. culicifacies, and A. stephensii which seems to be simi- 

 lar to the Agamodistomum described by Martirano* in A. claviger and to a simi- 

 lar parasite described by Alessandrini in A. maculipennis (E, S. R., 23, p. 663) is 

 here described.
