 Soc. Sci. Phijs. et ^at. Bordeaux, 190S-9, pp. 17-19).— The name Duboscqia 

 Jegeri is proposed for a parasite of T. lucifugus, whicli represents a new genus

 CoLLiNGE {Jour. Econ. Biol., 5 {1910), No. 2, p. 68).— The blossoms and bark of 

 the honeysuclile {Lonicera peridymenum) are reported to have been greatly 

 damaged by the common earwig.

The cotton stainer bug, C. P. Lounsbury {Agr. Jour. Cape Good Hope, 35 

 (1909), No. 5, pp. 613-616). — A general account of these bugs. The species 

 Dysdcrcus .supersUtiosus appears to be a formidable pest of the incipient cotton 

 industry of the Transkei and the extreme southeastern districts of Cape Colony. 

 The phylloxera board, H. Lowcay {Jour. Dept. Agr. So. Aust., 13 {1900), 

 No. 5, pp. .'i3G-'i3H). — In this extract from the report of the phylloxera board of 

 South Australia, it is stated that the vineyards of the State are still free from 

 the invasion of grape phylloxera. In 1908, 7,500 acres of vines and in 190^,

The sugar cane mealy bug (Pseudococcus calceolariae), J. B. Garrett 

 {Louisiana Stas. Bui. 121. pp. 3-19, figs. 7).— This insect is commonly known to 

 Louisiana sugar planters as the pou a pouche. Information received from some 

 of the oldest cane planters in southern Louisiana indicates that it was imported 

 on seed cane about 25 years ago and became established on some of the planta- 

 tions near the mouth of the Mississippi River. From that point, it worked its 

 way to districts around New Orleans, making its appearance at the Sugar Sta- 

 tion in 1S91. Inspections made in the fall of 1907 proved Jefferson, Plaquemines, 

 and Orleans parishes to be infested, while neighboring parishes were apparently 

 uninfested. In this country the species has also been rei)orted from Florida 

 and California. The author has observed this mealy bug on Johnson grass, 

 Sorghum halepcusc, and the saccharine sorghums, as well as on sugar cane; 

 and Calceolaria, Danthonia, Phormium tcnax, and Cordyline australis have been 

 also recorded as food plants of the species. 



Observations of the life history of the pest made at Audubon Park during 

 the season of 1907-8 are reported. " The females while quite young are fer- 

 tilized by the small winged males and normally begin to deposit eggs when 

 about three-fourths grown. If detached from the host plant and prevented from 

 reattaching, they will spin or exude the cottony mass and deposit eggs when 

 not more than half mature. . . . Fnder normal conditions it was observed that 

 a female would begin to exude the white secretion and oviposit in about 21 days 

 from time of hatching; however, when detached from the host plant oviposi- 

 tion would begin 7 to 10 days earlier. ... It was found that from 100 to 400 

 eggs were deposited in a single mass under normal conditions. . . . The eggs 

 hatch in from 4 to 7 days in warm weather, depending on the temperature and 

 humidity. ... In the early spring before the young canes have begun to joint, 

 the young mealy bugs, which hatch at that time, crawl up and attach themselves 

 in the leaf axils and get subsistence from the leaves. . . . The mealy bugs pre- 

 fer the stalk to the leaves and will leave the leaf axils and go to the nodes as
