The worst garden pests were Pieris (Pontia) monuste, L., and Plutella 

 maciilipennis, Curtis, attacking cabbages, radishes and turnips. 

 Hedges of orange- jasmine. {Murraya exotica) were injured by the 

 scales, Chrysomphalus aurantii, Mask., Lepidosaphes beckii, Newm., 

 and Saissetia hemisphaerica, Targ., and required spraying with paraffin 

 oil and soap emulsion. An undetermined species of Pseudococcus 

 was a new pest on peanuts, being abundant on the roots and pods of 

 the plants and reducing the crop by 50 per cent, or more. These 

 mealy-bugs were attended by large numbers of the dark-brown ant, 

 Prenolepis sp. The Termite, Eutermes morio, Lath., has been reported 

 as injuring sugar-cane seeds, i.e., sections of stalk, after planting in 

 the fields ; this probably occurs when the cane seed has been allowed 

 to lie about and become infested before planting. Damage to buildings 

 and furniture by this termite is much more common. Timbers of 

 houses or flooring should be soaked or painted with carboUneum or a 

 similar fluid before use ; furniture when attacked should be well 

 soaked with kerosene. The investigations and insect-control work 

 for the coming year are outHned. 



Gibson (E. H.). Relation of the Systematist to the Economic Worker. 



— Bidl. BrooMyn Entoni. Soc., Brooklyn, N.Y., xiv, no. 1, February 

 1919, pp. 1-3. [Received 6th October, 1919.] 

 Stress is laid upon the importance of co-operation between the 

 systematist and the economic worker in entomology. It is considered 

 that mutual assistance might be rendered by prompt determination 

 and return of specimens, by supplying references and bibliographies 

 of insects that are being studied by economic workers and by Umiting 

 monographic work to groups that are of economic importance. On 

 the other hand, full data should be sent when submitting specimens 

 for identification and a reasonable time should be allowed for deter- 

 mination. The ignorance of each other's work that exists between 

 these two groups of entomologists is deplored, and it is suggested 

 that young men starting as economic entomologists should choose some 

 small and well defined group of insects for taxonomic study and that 

 those who contemplate systematic work should spend at least a part of 

 two years doing biological and economic field work. 



Knight (H. H.). The' Male of Lygus univittatus with the Description 



of a new Lygus (Hemip., Miridae.) . — Bidl. BrooMyn Entoni. Soc, 



Brooklyn, N.Y., xiv, no. 1, February 1919, pp. 21-22, 1 fig. 



It is considered that Lygus univittatus. Knight, which has been 



described from the female only, and of which both sexes have now 



been taken on Crataegus, may probably become an apple pest, since 



apple red bugs now established as pests of cultivated apples came 



from Crataegus. Lygus (Neolygus) parrotti, sp. n., is described, having 



been found breeding on Viburnum sterilis and V. opulus in New York.
