of African bees. The work includes a list of 35 genera and some 783 forms 

 of African bees (including the subspecies of Apis meUifica), 53 of wbich species 

 are described as new in tlie present volume. Two colored plates of bees are 

 included in the work. 



The review is by W. M. Wheeler. 



A contribution on the bee fauna of the Lesser Antilles and the Bermudas, 

 H. Friese (Zool. Jahrb., 1008, *S'»/j. 11. No. 1, pih .33-// 0).— The author describes 

 2 new species and 1 variety and presents a list of 60 species known to occur 

 in the Lesser Antilles, Bahamas, and Bermudas. 



A Bembex preying on Glossina in Dahomey, E. Roubaud (Compt. Rend. 

 Acad. Sci. [Paris], 151 (1010), No. S, pp. oOo-oOS). — The wasp mentioned, which 

 apparently belongs to the genus Bembex, is one of the small number of species 

 that are known to capture blood-sucking flies. 



An introduction to the study of the ants of northern Colorado, W. W. 

 RoBBiNS (Univ. Colo. Studies, 7 (1010), No. Jf, pp. 215-222, figs. 3). — This paper 

 includes an artificial key to the genera and a preliminary list of the species 

 known to occur in northern Colorado, together with notes on their distribution 

 and habits and a partial list of papers mentioning Colorado ants. 



A note on the development of the gallfly, Diastrophus nebulosus, J. D. 

 IvES (Jour. Elisha Mitchell Sci. Soc, 26 (1010), No. 2, p. 76). — The author 

 reports the average number of larvje taken from blackberry knot galls in Janu- 

 ary to be about 85. " In certain of the galls the number of parasitic or in- 

 quilinus larvfe, namely, those of Torymus sackeni and Eurytoma sp. exceeded 

 those of D. nebulosus." 



A contribution to the biology of the stone-fruit sawfly, H. Schmidt 

 (Ztschr. Wiss. Insektenhiol., 6 (1010), Nos. 1, pp. 17-23, figs. 18; 3, pp. 86-92, 

 figs. 3). — The species here considered, Lyda nemoralis, was the source of con- 

 siderable injury to stone fruits in the vicinity of Griinberg, Silesia, in 1908. 



Further notes on the acarids attacking the tea plant, C. Bernard (Bui. 

 Dept. Agr. Indes Neerland., 1010, No, J/O, pp. 1-0). — Remedial measures for 

 Brevipalpus ohovatus and other acarids that attack the tea plant in Java are 

 discussed. See also a previous note (E. S. R., 21, p. 658). 



On some acarids indirectly related to tea culture, C. Bernard (Bui. Dept. 

 Agr. Indes Neerland., 1910, No. JjO, pp. 25-36, pis. 2). — Mention is made of an 

 acarid belonging to the genus Phytoptus that forms galls upon Indigofera 

 galegoides, a plant used in green manuring, and a red spider (Tetranychus sp.) 

 that appears in nurseries on the leaves of cinchona and manioc or cassava. 



A new gall mite on Crataegus osyacanthoides, J. Cotte (Compt. Rend. Soc. 

 Biol. [Paris], 68 (1010), No. 12, pp. 6.',3-6.',5, fig. i).— The author describes a 

 new species (Eriopliyes cratcegumplicans), which makes galls on the upper 

 surface of hawthorn leaves (C. oxyacanthoides). 



On the presence of a flagellate parasite of the genus Leptomonas in the 

 latex of three species of Euphorbiaceae, A. Lafont (Ann. Inst. Pasteur, 24 

 (1910), No. 3, pp. 205-219, figs. 7).— Further investigations (E. S. R., 22, p. 251) 

 have resulted in the discovery of this parasite in 2 additional species of Eu- 

 phorbia that occur on the Island of Mauritius, namely. Euphorbia thymifolia, 

 and E. hypericifolia. Its injury to the plant has been termed flagellosis. 



Of 205 E. pilulifcra plants examined. 70 were found to be parasitized. The 

 sap of 50 additional species was examined without finding the parasite. At the 

 time of writing the flagellate had been found or reported to occur in the neigh- 

 boring island of Reunion or Bourbon, in Madagascar near Tamatave, and at 

 Madras, India (E. S. R., 22, p. 288). It is said to have been discovered several 

 times in the intestines of lygeid bugs, captured upon parasitized plants.
