S. globuliferinii In the destruction of the soft scale (Coccus [Lecanium] 

 firspcridum). 



Destruction of Lecanium oleae by Sporotrichum globuliferum, J. de Camara 

 Pestana (Bui. Afir. Algcric ct Tuniaie, 15 (1909), No. 6. pp. U(i-l-i8, figs. 2).— 

 This is apparently the same account as the above except that a diflferent host is 

 given. 



The Aleyrodidffi of Barbados, C. C. Gowdey (West Indian Bui., 9 (1908), 

 No. //, pp. 3J,5-360, figs. 5). — Insects of the family Aleyrodid:ie are said to be 

 very plentiful in Barbados and the other West Indian islands. Nearly all of 

 the species are omnivorous and through such habits may become of considerable 

 economic importance. Tables for the separation and description are given for 

 the 3 species of Aleyrodicus and 8 species of Aleyrodes reported from the West 

 Indies. 



Miscellaneous papers. A new genus of Aleyrodidse, with remarks on 

 Aleyrodes nubifera, and A. citri, A. L. Quaintance ( U. S. Dcpt. Agi:. Bur. 

 Ent. Bui. 12, tech. scr.. pt. 9, pp. 169-174, figs. 2). — The new genus Paraleyrodes 

 is erected for a species of white fly occurring on Persea carolinensis in Florida 

 which was formerly described as Aleyrodes persecr. During the course of the 

 investigations in Florida of the citrus white fly P. persea; has frequently been 

 found upon the orange, avocado pear, and persimmon (?). A parasite bred 

 from the species has been given the manuscript name Encarsia variegatus. 

 ('ollection records are given showing A. nuMfera to occur in various localities 

 in North Carolina, Florida, Mississippi, Louisiana, and Cuba. It is stated that 

 previous records of A. citri from Cuba are incorrect and that all apparently 

 refer to A. nubifera. Specimens of A. citri in the Bureau of Entomology of 

 this Department were received from China and Japan and it has recently been 

 determined that A. aurantii, described by Maskell, from the northwestern 

 Himalayas in India is a synonym of A. citri. 



The classification of the phylloxera, B. Grassi and Anna Foa (Atti R. 

 Accad. Lined, Rend. CI. Sci. Fis., Mat. e Nat., 5. ser., 17 (1908), II. No. 12, pih 

 683-690). — Notes on the classification of the phylloxera. There are said to be 

 9 species in Italy besides the grape phylloxera. 



The cultural treatment in combating' the phylloxera, A. Wanner ( Wein- 

 bau u. Weinhandel, 26 (1908), Nos. 3'.). p. 35',: ',0. pp. 362. 363). — A discussion 

 of methods applied in dealing with this pest. 



Papers on deciduous fruit insects and insecticides. Additional observa- 

 tions on the lesser apple worm, S. W. Foster and P. R. Jones ( U. S. Dept. 

 Agr., Bur. Ent. Bui. 80, pt. 3, pp. 45-50, pi. 1). — The information here presented, 

 which is additional to that previously noted (E. S. R., 19, p. 858), is based upon 

 studies made at Siloam Springs, Ark., and in the insectary at Washington, D. C. 



During the spring of 1908 the larvje of Epinotia pijricolana were found feed- 

 ing in the apples and iilums around Siloam Springs. In July and August adults 

 were reared in numbers from larvte found in young vigorous growing shoots 

 and water sprouts of apple trees. Most of the injury to the twigs, however, 

 was done in June and July. Many observations made by the authors indicate 

 that a large part of the first brood larvae matures in the fruit, that the re- 

 mainder of the first brood and also the second brood mature in the young twigs 

 and water sprouts, and that the larger part of the later brood goes bai-k again 

 to the fruit. During the season the authors were unable to obtain a single speci- 

 men of EnarmoHia prunivora from twigs of the apple, but all specimens taken 

 appeared to be Epinotia pyricolana. 



The injury caused by the lesser apple worm early in the season is not so pro- 

 nounced nor are the larvae so abundant as those of the codling moth, but by 

 midsummer and fall there is a marked increase in -the number of larvip of this
