INSECTS AFFECTIXG PAKK AND WOODLAND TREES 2I3 



Coccinellicl or ladybeetle larvae prey on this species, ami certain miles, 

 like T y r o g 1 y p h u s ni a 1 u s Shinier, are also ciedited with this liabit. A 

 French investigator has ai)parently shown that this T y r o g 1 \- p Ji u s iloes 

 not feed on the eggs, but a species is described under the name of H emi- 

 sarcoptes coccisugus Lign., which does \aliant service in destroying 

 them. 



Three European birds, the blue tit, the long tailed tit and the tree 

 creeper are known to feed on this insect. 



Remedies. The hatching of the young the latter part of May renders 



it practicable to control this insect by applying a contact insecticide about 



June 1 in order to kill the young scale insects before the\' are protected by 



a thick scale.

Euonymus scale 



Chionaspis cnoiivini Comst. 



Dirtv blackish scale insects, about '/,(; incli in length and with one or more yellowish 

 specks at the smaller end, may be found on Euonymus and Celastrus associated with large 

 numbers of small snow-white tricarnate scales, on on^ end of which is a yellowish oval 

 cast skin. 



This insect is evidently a southern species, which ranges as far north 

 as New York city, and extends up the Hudson river valley for a short 

 distance. It has been brought to the writer's attention on several occasions 

 because of its great abundance on Euonymus. This species appeared to be 

 specially numerous in 1899, when it was received by the writer from 

 Fishkill, where it occurred on Euonymus ; from Great -Neck N. V., where 

 it abounded on lilac, and from Irvington, where it thrived on Prunus 

 pissardi and was stated to be present on other shrubs. It was also 

 received in 1900 from Blauvelt X. Y., where it infested Celastrus 

 scandens. [^^'f pi. 14, fig. 10-13 for colored figures of this pest and
