Banks (N,). New Mites, mostly economic (Arach., Acar.). — Entom, 

 News, Philadelphia, xxviii, no. 5, May 1917, pp. 193-199,, 

 2 plates. 



Among new genera of mites, or species of economic importance, 

 sent to the United States Bureau of Entomology for determination 

 are the following, which are described in this paper : — the Eupodid;^ 

 Notophallus viridis, sp. n., taken on wheat in Arizona ; Tetranychvs 

 antillarum, sp. n., on leaves of Leonotis nepekiefolia and Asclepias 

 curassavica in Porto Rico ; Tetranobia decepta, gen. et sp. n., on 

 barley in Arizona ; Tetranychina apicalis, gen. et sp. n., on white 

 clover in Louisiana ; Stigmaeopsis cehrius, gen. et sp. n., found in 

 Florida living in small colonies under dense white webs on leaves of 

 bamboo (Bamhusa metake). 



A key is given to the genera of the family Tetranychidae that 

 occur in the United States. Tetranychus lotus and T. banksi are 

 placed in a new sub-genus Eutetranychus. 



Tyroglyphus sacchari, sp. n., has been found in the West Indies on 

 sugar-cane and Chortoglyphns gracilipes, sp. n., in tobacco infested 

 with the cigarette beetle {Lasioderma serricorne). This is the first- 

 record of this genus in the United States.

The author points out the importance of the work which 

 entomologists can do in the present crisis in the way of increasing crop 

 production by the control of injurious insects. The United States- 

 Bureau of Entomology is organising its forces to disseminate through- 

 out the country essential information of this character by means of 

 publications and the activities of entomologists at field stations, 

 special attention being given to insect outbreaks involving staple 

 crops and to the preservation of stored grain, forage, etc. The Bureau 

 hopes to obtain the co-operation of all crop reporters and farm 

 demonstrators throughout the country, as well as the State and 

 Station entomologists and requests them to keep the central office at 

 Washington advised as to the status of insect pests in their vicinity. 

 The central office will then be able to tabulate and map the occurrence 

 of all injurious pests and indicate the sections which are threatened 

 with insect damage and the means of combating the danger.

Durmg the year ended 30th June 1916 nearly 97 per cent, of plant 

 importations inspected were passed as free from insect pests and 

 plant diseases. The following insects were found on imported nursery 

 stock and other plants : — Coccus hesperidum (soft brown scale), 

 Aspidiotus rapax [camelliae) (greedy scale), Saissetia oleae (black scale), 

 Chrysomphalus aonidum (Florida red scale), Aulacaspis rosae (rose
