The destruction of (Diaspis) Aulacaspis pentagona by means of Prospal- 

 tella berlesei, A. Berlese (Redia, 10 {1915), No. 1-2, pp. 151-218; abs. in 

 Intermit. Inst. Agr. [i?o?«e], Mo. Bui. Agr. Intel, and Plant Diseases, 6 {1915), 

 No. 3, p. 476). — ^A brief discussion of the mulberry scale and Its natural ene- 

 mies in Italy is followed by a somewhat detailed account of the establishment 

 and dispersion of the parasite P. berlesei, which has proved to be effective in 

 controlling this important pest. Earlier accounts of P. berlesei have been 

 noted (E. S. R., 32, p. 755). 



A bibliography of ten pages relating to the subject is appended. 



Descriptions of new species of Hymen optera, S. A. Ron web {Proo. U. S. 

 Nat. Mus., 49 {1915), pp. 205-249). — This article contains descriptions of 47 new 

 species of Hymenoptera with notes on certain other species and genera. Many 

 of the species are of economic importance with regard to forest trees, some of 

 them being important parasites, while others are defoliators. 



Among the new species of economic importance are the following : A tenthredi- 

 nid, Croesus castanecc, the larvre of which feed gregariously on the leaves of 

 Castanea dentata, at Falls Church, Va. ; several ichneumonids, namely, Pezo- 

 porus {Hchenkia,) tcnthredinaruni reared from a sawfly leaf miner on cherry 

 {Profenusa collares) at Geneva, N. T. ; Lagarotis i^irginianus and L. diprioni, 

 both primary parasites of Diprion lecontei, and Ilomalowma pteronidece, a pri- 

 mary parasite of Pieronidea corylus, all at Falls Church, Va. ; Excnterus di- 

 prioni, a primary parasite of D. lecontei, at Tomahawk Lake, Wis.; Moerophora 

 ncoclyti, parasitic on Ncoclytis capraca in Qucrcus arizonica in Arizona; Amer- 

 sibia prionoxysti, a primary parasite on Prionoxystus in chestnut at Falls 

 Church, Va. ; Scambus cvetrivorus, a parasite on Evctria buscJinclli infesting 

 Pinus ponderosa, at Fort Bayard. N. Mex. ; and the following braconids : 

 Apanteles {Apantcles) sibinidis, a parasite of Sibine stimulea, A. phobetri, a 

 parasite of Phobethron pithecium, and Gnamptodon ncpticulw, a primary para- 

 site on Nepticula castaneccfoliella, all at Falls Church, Va. ; Bassus coleophoroe 

 and Microbracon colcophorcc, both parasitic on Colcophora leucochrysclla feed- 

 ing on chestnut, the former at Charter Oak, Pa., and the latter at Falls Church, 

 Va. ; and Microbracon Jicmimctiw reared from Hemiinena plummerana, Plum- 

 mers Island, Md. 



The spread of Prospaltella berlesei in Piedmont in 1914, P. Voglino and 

 M. Savelli {Abs. in h'cv. Appl. Ent., 3 (1015), Scr. A, Xo. 5, p. 2')1). — Inspections 

 made in Piedmont from mid-September, 1914, to early in January, 1915, to de- 

 termine the intensity of parasitism of the mulberry or West Indian peach scale 

 {Aulacaspis [Diaspis] pentagona) by P. berlesei showed that the scale has been 

 largely destroyed in some localities. 



Biosteres rhagoletis sp. n., a parasite of Bhagoletis pomonella, W. C. 

 Woods {Camd. Ent., 47 {1915), No. 9, pp. 293-295, pi. i).— Notes relating to the 

 rearing of a braconid parasite of the apple maggot infesting blueberries in 

 Washington County, Me., are accompanied by a description by E. A. Richmond 

 of the parasite under the name of B. }-hagolctis. The parasite has since been 

 reared by Severin from puparia of the apple maggot obtained from the wild 

 crab or cultivated apples at Orono, Me. 



Four new encyrtids from Sicily and the Philippines, A. A. GiRAtrLX {Ento- 

 mologist, 48 {1915), No. 627, pp. 1S4-1SG). — Two of the species here described, 

 namely, Paralcptomastix abnormis and Epidinocarsis pseudococci, were reared 

 from Pscudococcus citri from Sicily. 



Cherry and hawthorn sawfly leaf miner, P. J. Parrott and B. B. Fulton 

 {U. S. Dcpt. Agr., Jour. Agr. Research, 5 {1915), No. 12. pp. 519-52S. pi i).— The 

 occurrence of Profenusa coUaris in New York State and its injury to the cherry 

 {Prunus spp.) first came to the attention of the New York State Station in June,
