G70 EXPERIMENT STATION RECORD. 



trap trees which may later be cut clown and burned. "Raupenleim and 

 Dendrolene might also be used upon the trunks and lower branches of 

 shade trees for preventing - the oviposition of eggs. A wash of lime 

 poisoned with Paris green, rendered sticky by a little glue, might be 

 used for the same purpose. 



General notes, L. 0. Howard (pp. 76-84). — Under this head Gelechia 

 piscipellis, Olliffiella cristicola, the white pine butterfly (Neophasia mcn- 

 apia), the strawberry weevil (Anthonomus signatus), the scolytid (Xyle- 

 borus tacky graphus), the harlequin cabbage bug, meal worms (Tenebrio 

 obscurus), the coccid (Aonidia fusca), the San Jose scale (Aspidiotus per- 

 niciosus), the common mealy bug of Europe (Dactylopius adonidum), and 

 the apple insects (Gaccecia responsana and C. excessana), are noted. 



Notes from correspondence (])]). 84-87). — Miscellaneous notes including 

 notes on the red winged starling (Agehcus plutnicus), the cottonwood 

 leaf miner, a migration of Colias cevsonia, the bollworm damage to 

 strawberry plants, scolytid beetle (Xyleborus pubcscens, Monarthrum 

 maliand. M.fasciatum), an unwelcome insect imported by the World's 

 Fair, Oreodera in the West Indies, a new locality for Bruchus obsoletus, 

 hippelates flies, early and new appearance of the horn fly, and a man- 

 infesting bot ( Dermatobia cyaniventris). 



The San Jose scale and its nearest allies, T. D. A. Cockerell 

 (U. 8. Dept. Agr., Division of Entomology Bui. 0, tech. ser.,pp. 31, Jigs. 

 15). — The characteristics which distinguish these closely related inju- 

 rious scale insects are considered. The characteristic features of scale 

 insects belonging to the subfamily Diaspinae and its genera are given 

 and a key to a number of species of Aspidiotus. 



it is noted that A. cydon'uv of Florida resembles A. rapax, and that 

 the Mexican .1. craicii, which is a fungus scale, is distinguished by the 

 exuviae not being dark. .1. pcrniciosus is recognized with difficulty in 

 the field, since A. ancylus, A. forbesi, and A, howardi closely resemble 

 it. It is therefore recommended that a field diagnosis be confirmed by 

 an examination of the insect beneath a compound microscope, if either 

 locality or plant is new. A. forbesi, recently described from Illinois, is 

 stated to have been found on apple trees in Mesilla, New Mexico. 



The microscopic characters of the adult female, so far as of diagnostic 

 value, are considered and figured with some detail. 



The absence of ventral glands in immature females is noted as a 

 diagnostic characteristic that is inconclusive. A close examination of 

 the posterior marginal lobes in A. pcrniciosus will enable one to distin- 

 guish it from other forms. The median lobes are large, upright, and 

 extero-marginally notched. The second lobes, though small, are dis- 

 tinctly set close to the first, varying slightly in shape, but inclining to 

 be pointed, and like the other lobes are externally notched. The pro- 

 cesses between the two lobes are well developed, close together, and of 

 nearly equal size.
