spruce, — food plants not heretofore reported, though whether 

 it can live for any length of time on these remains to be 

 seen. 



The elm-leaf beetle has attracted but little attention this 

 year, except in the north-eastern part of the State, where it 

 has appeared in abundance for the first time. Elsewhere it 

 was ajbout as plenty as usual, and Avas generally treated by 

 the tree wardens and city foresters with considerable success. 

 It has now been established that in the Connecticut valley 

 this insect has but a partial second brood, — so small, in 

 fact, that the injurj^ it causes is almost infinitesimal. 



The resplendent shield-bearer [Asjjidisca sjyleudo^'iferella) 

 has been abundant, attacking the apple leaves, but appears 

 to have caused but a small loss. The apple-leaf miner 

 (Tischeria malifoJwlIa) appeared in abundance in apple 

 leaves in the fall of 1901, and was present in large numbers 

 last spring. Careful studies on this inseet show that in 

 Massachusetts it is two-brooded, the adults appearing in 

 early spring and also in July. 



Two species of Aleyrodes have been doing a great deal of 

 damage in some parts of this State, — one in greenhouses, 

 the other out of doors on strawberries and other plants. 

 These species have long been considered identical with 

 Aleyrodes vc/jwran'oriwi Westw., a common European in- 

 sect, but the one on strawberries proves to be a new species. 

 Both have been very carefully studied here, and the new 

 one described and published with illustrations in the Can- 

 adian " Entomologist," under the name of Aleyrodes jpack- 

 ardi. The studies on the other species will be published 

 with illustrations as soon as completed. 



The life histories of several bugs have also been worked 

 out, and are now in the printer's hands for publication.
