there are insignificant when compared with those of the larger A. ceph- 

 ulotes, which is the real cacao pest. A peculiarity of A. octospinosa 

 is that it often removes the skin of ripe cacao pods. The best time for 

 destroying the nests with carbon bisulphide is just before the swarming 

 of the winged sexual forms from December to May.

Two large nurseries at Rutherford, N.Y., annually import large 

 quantities of plants from Europe, Asia and South America. The 

 plants are subsequently distributed to various parts of the United 

 States. All possible precautions are taken to see that no undesirable 

 insects, etc. are introduced, but, in spite of this, the following foreign 

 pests have recently become established in the vicinity of the nurseries : 

 Phytotmjza aquifolii, Gour., on English holly ; Rhyacionia {Evetria) 

 buoliana, Schiff. (European pine-shoot moth) on Pinus magnus ; 

 Agrilus viridis, L., var. fagi, Ratz., on rose stems ; Aspidiotus tsugae, 

 Marlatt, on Japanese hemlock and Myelophilus piniperda, L., on 

 Pinus sylvestris. In 1909, Dasychira -pudihunda, L. (European red- 

 tail), was bred from a pupa collected near Rutherford. In July 1915, 

 a mole-cricket was found feeding on the roots of plants [see this Review, 

 Ser. A, iii, p. 761]. In addition to these foreign species, noxious 

 insects from other parts of the United States occurred at Rutherford, 

 the most important being, the gipsy moth and Eriopus (Callopistria) 

 jloridensis, Guen. (Florida fern caterpillar). With one or two excep- 

 tions, the infestations were slight, but it is only a question of time before 

 they become more troublesome. This paper concludes with a list of 

 the various foreign insect pests which have become established in the 

 United States.

 of 1915. — Canadian Entomologist, London, Out., xlvii, no. 10, 

 October 1915, pp. 326-328. 



Among a number of insects introduced into New Jersey in nursery 

 stock in the spring of 1915, were the following : Coccus hesperidum, L., 

 on bay trees, and Chrysomphalus dictyospermi, Morg., on palms, from 

 Belgium ; Lepidosaphes idmi, L., on boxwood ; Rhyacionia (Evetria) 

 buoliana, Schiff., on Pinus 7nontana, P. mughus and P. ivateriana ; 

 the carnivorous beetles, Hister stercorarius, HofE., in soil round rhodo- 

 dendron roots ; the Hydrophilid beetle, Cercyon haemorrhoidalis, F., 

 on rhododendrons, from Holland ; Targionia biformis, Ckll., and 

 Isosoma orchidearum on orchids, from Brazil, Colombia and Venezuela ; 

 Aulacaspis rosae, Bouche, on rose stocks, Apatela rumicis on roses, and 

 A. auricoma on shrubs, from France ; Parlatoria pergandei, Ckll., on 

 maples, and Pseudaonidia paeoniae, Ckll., on azaleas, from Japan ; 

 Chrysomphalus perseae, on orchids from Central America ; larvae of 

 Ortalid flies and weevils round roots of blue spruce, from Holland ; 

 Ichneumonids of the genera Itoplectis and Brachycryptus from cocoons 

 on azaleas from Japan ; these last may prove to be useful parasites.
