Coccinellid or ladybeetle larvae prey on this species, and certain mites, 

 like T y r o y i y p h u s m a 1 u s Shimer, an; also credited with this habit. A 

 French investigator has apparently shown that this Tyroglyphus does 

 not feed on the eggs, but a species is described under the name of Hem i- 

 s a r c o p t e s c o c c i s u g u s Lign., which does valiant 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 ap|)lying a contact insecticide about 

 June I in order to kill the young scale insects before they are protected by 

 a thick scale.

Euonymus scale 



C/uoiiaspis cnoiiynii Comst. 

 Dirty blackish scale insects, about '/.e inch 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 lirought to the writer's attention on several occasions 

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

 specially numerous in i8gg, Avhen it was received by the writer from 

 Fishkill, where it occurred on Euon)-mus ; from Great Neck N. Y., where 

 it abounded on lilac, and from Irvington. where it thrived on I'runus 

 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. [.SYv pi. 14, tig. 10-13 for colored tigiu-es of this pest and
