672 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 



INSECTS INJURIOUS TO THE DOGWOOD. 



Cornus Jiorida. 



I. Antispila cornifoliella Clem. 



Order Lepidoptera ; family TiNEiDiE. 



The larva lives iii a blotch mine, from which it cuts out a case in which 

 it pupates on the ground. 



The larva mines the leaves of Cornus Jiorida in September. It may 

 possibly be a variation of nysscefoliella. The larvae of the insects are 

 very like each other, but I do not know whether that of cornifoliella 

 undergoes the same change of coloration after the last molting as that 

 of nysscefoliella. Its mode of preparing for pupation is the same as 

 the previous species, but whilst the individuals of nysscefoliella on a 

 single tree are almost innumerable, those of cornifoliella are not abun- 

 dant. (Clemens.) 



Larva. — The head aud shield dark brown ; body nearly white, with seven minute 

 black points along the dorsum, and eight on the central surface, somewhat larger 

 aud more distinct. 



Moth. — Head, face, labial palpi, and forefeet dark brown. Antennae dark brown; 

 basal joint somewhat ocherous. Forewings rather dull dark brown, with a coppery 

 hue. Near the base is a rather narrow golden band, not constricted on the fold, and 

 rather indistinct toward the costa, where it is somewhat suffused with a coppery 

 hue, and nearest the base on the inner margin. At the apical third of the wing is a 

 small golden spot, aud nearly opposite, on the inner margin, another of the same 

 hue, with the hinder portion of the wing tinged with a bright reddish coppery hui>, 

 cilia dark grayish. Hind wings purplish brown ; cilia somewhat paler, with a cop- 

 pery hue. (Clemens.) 



2. Coleophora cornella Walshingham. Lives in curiously shaped case 

 on leaves of Cornus puhescens, in California. 



INSECTS INJURIOUS TO THE BOX. 



Buxus sempervirens. 



1. The EUROPEAN BOX PSYLLA. 



Psylla buxi Linn. 



While making some observations for the Bureau, Mr. Koebele found 

 toward the end of May, in the garden of Mr. James Angus, near New 

 York City, large numbers of a llea-louse infestiug box. The insects (at 

 that time mostly larvfe or pup?e and a few imagos) thickly crowded the 

 young growth of the plants, and the whole hedge showed at the first 

 glance a sickly appearance, the tender shoots being more or less yel- 

 lowish in color and evidently dying. In our breeding cages the imagos 

 continued to develop throughout the month of June, but outdoors no 

 further observation on the life-history of the insect could be made. 

 The species proved to be identical with the European Box Psylla,
