weevil, and other species" from being carried into the granary; (2) the 

 thorough inspection, quarantining, and disinfection of grain bins and 

 machinery before the grain is stored; (3) the destruction of refuse 

 matter and the observance of scrupulous cleanliness; (1) either refitting 

 old warehouses and mills, especially in warm latitudes, or constructing 

 new ones designed to exclude insects; (5) the use of metal in the place 

 of wood in the spouts, etc., in mills to exclude the Hour moth; (6) the 

 storage of grain in large bulk; (7) storage in well- ventilated and cool 

 places to prevent heating; (8) the use of napthaleue, especially in the 

 case of small samples inclosed in tight receptacles. 



Notes on scale insects, T. D. A. Cookrell (California Fruit 

 Grower, 21 (1897), No. 1, p. 5). — The author notes a new scale insect 

 which he designates as Lecaniwm magnoliarum as havingbeen imported 

 from Japan and as found on young trees of a deciduous magnolia in 

 the Japanese nursery at San Jose. The scale belongs to the subgenus 

 Eulecanium and maybe distinguished by its large size and elongate 

 form. It is 8 mm. long, 4.] mm. wide, and 2.] mm. high; of an elongate, 

 oval shape, and of a dark-brown color. The subdorsal area is irregu- 

 lar, mottled with black, or blackish. The surface is granular; the legs 

 are very slender; the antennae 8-jointed, with a formula varying from 

 3 (451) (28) 67 to 3 (41) .52 (86) 7. 



The author says that by no means should the insect be allowed to 

 spread, as it is very likely that it may infest other plants than the 

 magnolia, and even if it does not it will become troublesome in gardens. 



On a new Myxosporidium of the family of G-lugeideae, L. 

 Leger (Gompt. Rend. Acad. Sci. Paris, 125 (1897), No. i. pp. 260-262).— 

 On the larvae of Simuliwm ornatum the author found a .Myxosporidium, 

 which he describes as Glugea varians. The abdominal region of the 

 affected larvae is dilated and of a milky-white color, contrasting strongly 

 with the somber tint of the normal individual. Dissection and the use 

 of a lens showed the body cavity of the larvae to be filled with masses 

 of parasites free and forming whitish sacs with irregular contours. 

 In some badly affected larvae the excessive growth of the parasitic sacs 

 produces hernia on the abdominal surface. A microscopic examination 

 of the sacs shows them to be thin, transparent, and tilled with spores. 

 These are ovoid, refracting bodies, with a vacuole at the larger end. 

 Treated with iodin they show a filament, 15 to 20 times longer than them- 

 selves, that arises from the pointed end. The spores are of 2 sizes, one 

 from 4 to 5/.<, the other about 8/< in diameter. Some of the sacs contain 

 only microspores. These are united in groups of 8 or inclosed in a frail 

 skin. The macrospores are gathered into masses of different sizes 

 and each inclosed in a thin envelope. The octo-spored cysts recall 

 Telohania eontejeani of Henneguy, which is parasitic in the muscles of 

 the crayfish. 



Swarming box for bees, A. H. Huff (Amer. Agr. (middle ed.), 59 (1S97), No. 21, 

 p. 637). — An ordinary 10 to 12 in. square box at the end of a pole containing a little 

 honey as bait. Small boles bored in it allow circulation of air. When a swarm 

 settles, tbe box is pushed up over the cluster.
