walnut, Japan walnut, loquat, red dogwood, juneberry, rose, sumac, 

 Photinia glauca, and the Carolina poplar. 



An annotated list of the 134 species of Aspidiotus is given. In a 

 postscript the author accepts Leonardos new genus Odonaspis and drops 

 a subgenus proposed by himself of which A. secretus was the type. 

 He objects to the grouping of the species by Leonardi 1 which throws 

 into the same genus (Aonidiella) such different forms as A. auranlii, 

 pemiciosus, and mimosa, while it places pemiciosus and ancylus in sepa- 

 rate genera. 



Distribution of the San Jose scale in Virginia, W. B. Alwood 

 ( Virginia Sta. Bui. 66, pp. 77-90, figs. 3).— In May only 2 infected local- 

 ities were known in the State, but as a result of personal inspection 

 and correspondence since then the number of localities has been 

 increased to 20, distributed through the entire State in 16 counties, 

 including some 60 premises. Since the introduction of the pest into 

 the orchard in Roanoke County 6 years ago it has increased so as to 

 involve 10,000 trees in this county and 4,000 in the adjacent one of 

 Botetourt. The distribution of the scale in the United States is also 

 noted. 



During the year all but a few small nurseries were inspected and 

 were carefully watched. In this work the nurserymen of the State 

 cooperated with the best of will. Where stock is known to be infested 

 the author seems to advise its entire destruction and the treatment of 

 only such stock as is suspected. Little faith is placed in washes for 

 this latter purpose, fumigation being thought best. 



For the purpose of fumigation of nursery stock, a two-rooined tight 

 board building lined with paper and having aground floor is described. 

 The partition dividing the 2 rooms is tight, so that one room may be 

 filled whi.le fumigation is going on in the other. 



More about the San Jose scale, C. F. Baker (Alabama College 

 Sta. Bid. 86, pp. 151-156, figs. 2). — The author states that the inspection 

 of several nurseries in Alabama during the spring revealed the fact 

 that this insect occurred but rarely or not at all on stock that was 

 moved every 3 years, and he seems to advise such a movement of 

 stock for the purpose of getting rid of the scale. The plan, it is stated 

 on the authority of nurserymen consulted, is perfectly practicable. 



Passing over a compiled list of the food plants of the insect, it may 

 be noted that the Early Richmond cherry seems to be exempt from the 

 San Jose scale. Trees of this variety have been growing with their 

 branches interlocked with those of a pear that had been killed by the 

 scale and yet remained uninfested. Again, two cases are noted where 

 the Early Richmoud variety was grafted upon Mahaleb stock. The 

 shoots of the latter had sprung up below the graft and were badly 

 infested, while none at all were to be fouud on the trees themselves.
