trees against the attacks of man, cattle, and insects. No leaf-eating caterpillars, 

 no aplud«, and no coccids were seen on the trees, and no leaf-cutting ants ever 

 defoliate them. 



Notes on Trichogramma minutum, S. C. Habland (West Indian Bui., 15 

 (1915), No. 3, pp. 168-175). — The author's experiments with this important 

 parasite indicate that it parasitizes the eggs of the sugar-cane borer, the 

 bolhvorm, the fall army worm, Utetheisa ornatrix, Calpodes ethlius, and an 

 unidentified cutworm. It is pointed out that other egg parasites confine them- 

 selves to one particular host. Experiments show that T. minutum will not 

 parasitize the eggs of a nonlepidopterous insect nor of a spider. In everj' case 

 T. minutum was a subsidiary parasite, as the number obtained in the field 

 was always less than that of the other egg parasites of the same host. Work 

 is being carried on with V. ornatrix, with a view to making use of it in the 

 control of the sugar-cane borer through serving as a host for T. minutum. 



A nearctic species of Dolicliurus, S. A. Rohwee (Proc. Ent. Soc. Wash., 18 

 (1916), No. 4, pp. 212, 213). — Dolichurus greenei n. sp. is described from Falls 

 Church, Va. 



On the life history and successful introduction into the United States of 

 the Sicilian mealy bug parasite, H. S. Smith (Jour. Econ. Ent., 10 (1917), 

 No. 2, pp. 262-268, jyls. 2, figs. 5). — This paper relates to the Italian encyrtid 

 parasite of mealy bugs, described by Girault as Paralcptomastix abnormis 

 (E. S. R., 34, p. 456), accounts of which have previously been noted (E. S. R., 

 34, p. 451). 



Reproduction took place so rapidly that before many months large colonies 

 were placed in the orchards of southern California. The parasite is now quite 

 thoroughly distributed throughout the mealy-bug infested sections of the State 

 and has become established in practically every colony. In many of the orchards 

 under investigation it has successfully passed through two fumigations, probably 

 as larvae and pupae within the young mealy bugs. Spraying does not destroy it, 

 except where it is successful in killing the mealy bugs. While it will occa- 

 sionally deposit eggs in Pseudococcus bakeri, the author has never succeeded 

 in rearing it from this host. In work in Hawaii Swezey has succeeded in 

 getting it to breed upon P. sacchari, though it does not thrive greatly on that 

 species. 



Some new Australian chalcid flies, mostly of the family Encyrtidag, A. A. 

 Girault (Insecutor Inscitice Menstruus, 5 (1917), No. 1-3 pp. 29-37). 



New Australian chalcid flies, A. A. Gikault (Insecutor Inscitiw Menstruus, 

 5 (1917), No. 4-6, pp. 92-96).— The author erects a new genus (Paramyiocnema) 

 and describes six species as new to science. 



A chalcid parasite of the pink bollworm, A. A. Gikault (Insecutor Inscitiw 

 Menstruus, 5 (1917), No. 1-3, pp. 5, 6). — Under the name Stomatoceras per- 

 torvus, the author describes a parasite reared from pupfe of (Gelechia) Pectino- 

 pliora gossypiella at Honolulu, Hawaii, which has previously been referred to as 

 Hockeria sp. 



Two bethylid parasites of the pink bollworm, S. A. Rohwer (Insecutor 

 Inscitiw Menstruus, 5 (1917), No. 1-3, pp. 1-3). — Perisierola nigrifemur Ashm. 

 i<: recorded as parasitic on the larvae of the pink bollworm (Gelechia) Pectino- 

 phora gossypiella in Brazil. P. emigrata, which has been reared in great num- 

 bers from the larva of the pink bollworm in Honolulu, Hawaii, is here described 

 as new. Specimens from Texas referred to under the name P. distinguenda 

 and recorded as parasites of Bruchus prosopidis and Bruchus sp. are con- 

 sidered to be P. emigrata.
