768 EXPERIMENT STATION RECORD. 



Descriptions and brief notes on the life history are given of the fol- 

 lowing additional scale insects: Oyster-shell bark louse {Mytilaspis 

 pomorum), scurfy bark louse (Ohionaspis furfurus), rose scale (Diaspis 

 rosce), cottony maple scale [Pulvinaria innumerabilis), grape scale (As- 

 pidiotus uvce), and peach lecanium (Lecanium nigrofasciata). 



The bulletin concludes with remarks on the natural enemies of scale 

 insects and gives directions for remedial treatment. 



The life history of Schizoneura lanigera, W. B. Alwood (Science, 

 n. ser., 8 (1898), No. 195, p. 400). — In a paper read before Section F of 

 the American Association for the Advancement of Science, the author 

 states that breeding records show that the root and stem forms of this 

 insect can be colonized from root to stem or the reverse. Many of the 

 agamic wingless females at Blacksburg, Virginia, survive the winter 

 exposed on aerial situations. Twelve generations of agamic viviparous 

 females have been observed from May 12 to September 20. At this 

 time winged agamic viviparous females were observed m all colonies 

 examined. Under normal conditions these proved migratory, but in 

 confinement they produced 4 toG young, which were sexed individuals. 

 These are small, beakless, and are produced in about the proportion of 

 2 females to 1 male. After copulation the females lay one egg, which 

 remains dormant during the winter. 



From long observations it is concluded that in southern latitudes 

 agamic individuals continue in an unbroken chain and oviparous repro- 

 duction plays no important role in the life cycle. 



The proposed attempt to introduce Blastophaga psenes into 

 California, L. O. Howard (Science, n. ser.,8 (1898), No. 195, pp. 399, 

 400). — In a paper read before Section F of the American Association for 

 the Advancement of Science at its meeting in August, 1898, the author 

 gives an account of the attempts made to introduce these insects into 

 California. The practice of fig growers in utilizing this insect which 

 inhabits the wild Capri fig is stated, and the belief is expressed that if 

 the Blastophaga could be established in California a fig could be grown 

 quite as good as those imported. Capri figs with their insects have been 

 repeatedly imported, but attempts to establish the species have not 

 been very successful. The author believes the time has come to carry 

 on these experimants in a larger way and believes it will be successful.
