 work with insect pests in British Guiana during the year includes lists of eight 

 species of thrips of economic importance of which two are new to science, 

 identified by J. D. Hood of the U. S. Department of Agriculture ; and a list of 

 Aleyrodidse of British Guiana, identifications of several of which have been 

 made by A. L. Quaintance, likewise of this Department. A number of hymen-

 Agr. Soc. Scot., 5. scr., 2S {1916), pp. 107-139, figs, i^).— This is the usual annual

Parthenogenesis in Anthothrips verbasci, A. F. Shull {Rpt. Mich. Acad. 

 Sci., 16 {1914), PP- 46-48). — The author reports experiments which show that 

 A. verbasci was reproduced parthenogenetically. It is pointed out that the 

 discovery of parthenogenesis in this species, a form which gives more evidence 

 of sexual reproduction in nature than almost any species in the region around 

 Ann Arbor, greatly reduces the probability that sexual reproduction is of com- 

 mon occurrence in Thysanoptera as a group.
