control measure the trees should be sprayed with Black Leaf 40, 

 1 pt. to 50 gals, water, with or without lead arsenate and fungicides before 

 the blossoms open, and again just after the petals fall. A European 

 8SiV7^y, Emphytus cinctus, L., was present in the pith of the cut ends of 

 rose stalks imported from France, The larvae pupate in this position 

 and apparently do not bore into the plants in an injurious manner. 

 In Europe the larva feeds on the leaves of rose and raspberry and is 

 regarded as injurious. It can be killed by spraying the foliage with 

 lead arsenate or hellebore. Saperda vestita, Say (linden borer), caused 

 injury to lime trees by tunnelKng under the bark near the base ; a 

 fungus usually followed the attack, causing the decay and breaking of 

 the tree. This species apparently requires two years for its develop- 

 ment. Infested trees should be examined twice a year, and carbon 

 bisulphide injected into the burrows. Two Psyllids, namely, Psylla 

 huxi and Spanioneura fonscolombei, occurred on twigs of boxwood ; 

 they were probably introduced from Europe on nursery stock. Typo- 

 phorus canellus, F., (strawberry root worm) injured the leaves of 

 strawberry, but the roots were not damaged. Normally, the first 

 generation of adults feeds on the leaves during May, and the larvae 

 of the next generation live in the soil, feeding on the roots and pupating 

 in July. Adults emerging in August feed on the leaves for a time, 

 then hibernate. A thorough spraying with lead arsenate in May and 

 August should prevent serious damage. Pemphigus tessellatus, Fitch, 

 occurred on silver maple ; the tree was successfully sprayed with 

 kerosene emulsion. Termites, probably Leucotermes flavipes, were 

 recorded from one locality, where the timber of a dwelUng house was 

 infested. Chrysanthemums, marguerites and other Composites were 

 occasionally attacked by a leaf-miner, Phytomyza chrysanthemi, Kow. 

 A new leaf weevil, Polydrusus impressifrowi, Gyll., was found under 

 birch during June. This species is a minor pest in New York, where it 

 feeds on the buds and young leaves of birch, poplar and willow. The 

 Tortricid, Tortrix albicomana, Clem., was found on oak, and has also 

 been reported on rose and Aquilegia canadensis. An early spraying 

 with lead arsenate would prevent serious injury. Macronoctua onusta, 

 Grote, was present in small numbers in the roots of iris wherever the 

 latter was grown. The only control measure is to destroy the infested 

 root-stock when resetting the plants. Bermuda lilies grown from bulbs 

 imported from Japan were injured or completely destroyed by 

 Rhizoglyphus hyacinthi, Boisd. (bulb mite). The mites could 

 probably have been killed by dipping the bulbs in fir tree oil or 

 nicotine solution. There is at present no systematic inspection of 

 bulbs imported into Connecticut. Peaches iu one locality were injured 

 by the beetle, Diplotaxis atlantis, Fall., a native species which normally 

 feeds on woodland trees. A heavy coating of lead arsenate on the buds 

 and unfolding leaves might prevent serious damage. Beets grown for 

 seed were infested in one locality with Aphis rumicis, L., Macrosiphum 

 solanifoliiy Ashm., and Myzus persicae, Sulz. Coccinellids were 

 abundant, and many of the Aphids were parasitised by Lysiphlebus. 

 The weeds, Chenopodium album and Amarantus retrojlexus, were 

 growing throughout the field. At the time of investigation, in the 

 middle of July, treatment was useless, but it is probable that nicotine 

 solution applied at a high pressure two or three weeks earlier would 

 have killed most of the Aphids.
