tions. Accounts are given of the first two meutioned and means for combat- 

 ing them. 



Rules and regulations of the South Carolina Crop Pest Commission govern- 

 ing the transportation of materials from cotton boll weevil territory {^outh 

 Carolina ist{i. Circ. 16, pp. 3). — The text of these rules and regulations is given. 



Bules and regulations of the South Carolina Crop Pest Commission govern- 

 ing the transportation of cotton seed originating outside of boll weevil 

 infested territory (South Carolina Sta. Circ. 15, pp. Jf). — The text of these rules 

 and regulations is given. 



Notes on the negative geotropism of Corythuca ciliata, Adalia bipunctata, 

 Coccinella 9-notata, and Megilla fuscilabris, II. B. Wkiss {Jour. Econ. IJnt., 

 6 (1913), No. 5, pp. Jf07-40!t). — The author concludes that "other factors being 

 equal, sunlight and possibly high temperatures shorten the distance covered 

 during a geotropic response and also the time during which the beetle responds 

 to such stimuli, thereby giving the beetle a greater chance to find food. Sun- 

 light does not, however, influence the direction of locomotion or the negative 

 geotropic position assumed by the beetle." 



A rhododendron borer (Corthylus punctatissimus), E. P. Felt (Jour. Econ. 

 Ent., 6 {1913), xAo. 5, p. 4^7). — This ambrosia beetle was found working in 

 rhododendron stems in New York City, where it seems to be a rather serious, 

 though distinctly local, pest. It can be controlled by cutting out and burning 

 the affected stems. 



Notes on Oregon Coccinellidae, H. E. Ewing (Jour. Econ. Ent., 6 (1913), No. 

 5, pp. 40-^407). — The author discusses the relative economic importance of dif- 

 ferent species of lady beetles found in Oregon, their migration and hibernation 

 habits, and the emergence of adults in spring, and presents miscellaneous notes 

 and observations. 



The presence and percentage of cantharidin in Epicauta adspersa, J. 

 Schroder (Rev. Inst. Agron. Montevideo, 1913, No. 12, pp. 9-14) ^ — ^Analyses 

 made of E. adspersa collected in Uruguay, by Siegfried's method, show the 

 presence of 0.77 per cent of cantharidin in the fresh material and 1.72 per cent 

 after drying at 45° C. 



A brief review of our species of Magdalis, with notes and descriptions of 

 other North American Rhynchophora, H. C, Fall (Trans. Amer. Ent. Soc, 

 89 (1913), No. 1, pp. 23-72). — This paper includes a synoptic table for the sepa- 

 ration of 15 species of the genus Magdalis, of which 6 species are described as 

 new. Biological notes relating particularly to their host plants are included. 



Descriptions of and notes on weevils belonging to a number of other genera, 

 namely, Trichomagdalis n. g., Lixus, Dinocleus, Phyllotrox, Eulyptus, An- 

 thonomus, Epimechus, Orchestes, Conotrachelus, Acallodes, Auletes, Baris, and 

 Pycnobaris, follows. 



The present status of control measures for the rhinoceros beetle (Oryctes 

 rhinoceros) in Samoa, K. Friederichs (Tropenpflanzer, 17 (1913), Nos. 10, pp. 

 538-006, figs. 4; 11, pp. 603-619, figs. 9; 12, pp. 660-675, figs. S).— A discussion 

 of the rhinoceros beetle, an account of which by Jepson has previously been 

 noted (E. S. R., 28, p. 561). The subject is dealt with under the headings of 

 direct and indirect measures, natural enemies being discussed under the latter. 



An unusual type of injury due to a thrips, J. R. Watson (Jour. Econ. Ent., 

 6 (1913), No. 5, pp. 413, 414, pi. 1). — The author reports observations of a new 

 thrips (Cryptothrips floridensis), which is a camphor tree pest at Satsuma, Fla. 

 The larsiB attack the buds, in some instances killing them outright. Later they 

 attack the younger twigs — feeding in groups — causing the bark to dry up and 

 crack.
