'Gratichneumon annuhtor, F., and Cry plus minator, Grav. The 

 Tachinid flies, Frontina {Masicera) tenthredinidarum, Towns., and 

 Exorista spp, were bred in New Brunswick and England respectively. 

 The bug, Apateticus (Podisus) modestus, Dall., is predaceous on the 

 larvae in Quebec and New York, and is known to occur in New Jersey. 

 The fungus, Isariafarinosa, Fr., is found on cocoons in Canada and in 

 England, destroying the insect within. This fungus may prove an 

 important check under favourable climatic conditions. Artificial 

 methods of control include :— (1) spraying with lead arsenate, at a 

 maximum strength of 3 lb. to 50 gals, water ; this method is applicable 

 •only to small areas ; (2) the collection and burning of cocoons ; 

 (3) banding of trees with tanglefoot, etc. ; (4) the planting of other 

 trees, especially white pine, among the larches. An infestation may 

 occur during 1916, hence trees should be carefully watched during 

 May, and preparations made for spraying if necessary. 



Walden (B. H.). Experiments in Controlling the White Pine Weevil 



in 1915. — Rept. Connecticut Agric. Expt. Sta., 1915, New Haven, 

 1916, pp. 134-136. [Received 25th April 1916.] 

 During 1914, white pines infested with the white pine weevil {Pissodes 

 strobi) were sprayed with lime-sulphur, one part in eight parts water, 

 and with lead arsenate, 3 lb. in 48 gals., on 7th and 11th May 

 respectively. Collections of weevils were also made with a net on 

 several dates between 7th May and 10th June. Both in 1914 and 

 1915 lime-sulphur gave the best results, while in 1915 weevils were 

 about half as numerous in trees sprayed with lead arsenate and treated 

 with a net as in the check trees. Experiments in this direction are 

 "being continued. 



The Juniper Web-Worm, Dichomeris marginellus, Fabr. — Rept. 

 Connecticut Agric. Expt. Sta., 1915, New Haven, 1916, pp. 137-139, 

 2 figs. [Received 25th April 1916.] 



Larvae of Dichomeris marginella, F., were found on Juniperus 

 communis in several localities during May. Other records of the 

 insect have been made in Maine and New York. The moths appear 

 early in June. The lar^'ae feed on dried or fresh leaves which are 

 webbed together, and pupate in the same position. There may be 

 more than one generation annually. In the event of a serious attack, 

 a thorough spraving with lead arsenate while the larvae are small 

 should prove satisfactory. 



Three Species of Scale-Insects new to Connecticut. — Reptt. Connecticut 



Agric. Expt. Sta., 1915, New Haven, 1916, pp. 139-140, 1 plate. 



[Received 25th April 1916.] 



Leucaspis japonica, Ckll., was introduced into Connecticut on 



Norway maple and California privet during 1914. Specimens were 



collected in August 1915 on silver maple at New Haven. Lepidosaphes 



newsteadi, Sulz., was recorded on Sciadopitys verticillata (umbrella 



pine). This species has been described from Europe on tea and the 



variety toJcionis on Codiaeum from Japan. Diaspis echinocacti, Bch., 



var. cacti, Comst., occurred on Phyllocactus in a greenhouse. It will 



probably not live out of doors in Connecticut and remedies used 



against other scale-insects will probably prove effective for this species.
