ECONOMIC ZOOLOGY — ENTOMOLOGY. 765 



Bees and fruit fertilization, R. Beuhne (Jour. Dcpt. Agr. Victoria, 7 (1909), 

 Ao. 11, itp. 693-1)06, fig. 1). — The importanco of the houey bee iu the fertiliza- 

 tion of fruit is emphasized in this account. 



On the habit with certain Chalcidoidea of feeding at puncture holes made 

 by the ovipositor, L. O. Howard (Jour. Econ. Ent., 3 (1910), No. 3, pp. 257- 

 260). — The chalcidoid species noted are Tetrastichus asparagi, Aphelinus myti- 

 laspidis, and .1. fusripcnnifi. 



Two new parasitic Hymen optera, J. C. Crawford (Proc. Ent. Soc. Wash., 12 

 (1910), yo. 3, pp. l-'io, l'i6). — Two chalcidids, Coclopisthia diacvisia; reared from 

 Diacrisia virginica at Rocky Ford, Colo., and MerisuS mordeUistenw reared 

 from MordcIIixtciia ustulatd in Ohio and Indiana, are described as new. 



A parasite of the asparagus beetle, H. T. Febnald (Massachusetts Sta. Circ. 

 28, pp. 2). — The author records observations relating to the parasitism of eggs 

 of the asparagus beetle by a chalcidid as previously noted (E. S. R., 22, p. 557). 



[The toxic effect of the food of the host upon its parasites], A. C. Morgan 

 (Proc. Ent. Soc. Wash., 12 (1910), No. 2, p. 7^).— The author thinks the lack 

 of parasitism of the tobacco hornworms (Phlegethontius spp. ) by Apanteles, 

 when feeding upon tobacco, to be due to the toxic effect of the nicotine con- 

 tained in the tobacco. 



The chalcidoid parasites of the common house or typhoid fly (Musca do- 

 mestica) and its allies, A. A. Girault and G. E. Sanders (Psyche, 11 (1910), 

 No. Jf, pp. 1^5-160, figs. //). — In this third paper on the subject (E. S. R., 23, 

 p. 666) the authors describe a new North American genus and species of the 

 family Pteromalidse. namely, Muscidifiirax raptor. In addition to the house fly 

 this parasite was reared by the authors from the puparia and, rarely, from 

 the larvte of the screw-worm fly and Phormia regina. 



Biological notes are included. 



Observations of the early stages of two aphidiine parasites of aphids, 

 P. H. Timberlake (Psyche, 17 (1910). No. 4, pp. 125-130, figs. 2). — Praon sintu- 

 lans and Aphidius rosw ( ?) are the species noted. 



Habits of Lysiphlebus sp., C. H. Withington (Trans. Kans. Acad. Sci., 21 

 (1907), pt. 1, pp. 138-11(0). — The braconid here considered, which apparently 

 represents a new species, was found to be an important parasite, at Manhattan, 

 Kans., of Apliis uiaidis. It was found that at a mean daily teuiperature of 

 62.6° F. the parasite passed from egg to adult in an average of 16.8 days, with 

 13 and 23 days as extremes. A single female successfully parasitized from 1 to 

 147 individuals, with an average of 34. Fertilized females were applied to 8 

 species of plant lice, but of these only A. cucumeris, ISiphocoryne avcnw, and 

 Toxoptera graminum were parasitized. In case of the green bug under a daily 

 mean temperature of 60° the parasite passed from egg to adult in an average 

 of 17.5 days. 



On the hymenopterous parasites of Rhynchota, C. Morley (Zoologist, Jf. 

 scr., 13 (1909), Nos. 150, pp. 213-225; 152, pp. 309-31.',; 153, pp. 3 ',0-3. ',7 ; 155, 

 pp. J,27-Ji37). — An annotated list of more than 140 species of IIemii)tera attacketl 

 by hymenopterous parasites, with references to the literattn-e. 



The animal kingdom. — Cynipidae, K. W. von Dalla Torre and J. J. Kief- 

 FER (Das Tierreich. Berlin, 1910, No. 2.',, pp. XXXV+S9t, figs. .',22).— Thla syn- 

 opsis of the hymenopterous gall making family Cynipid:e includes a bibliog- 

 raphy of the literature referred to, a systematic index of the family, and a 

 plant index in addition to the general index. 



How to keep bees for profit, D. E. Lyon (New York, 1910, pp. \ II +329, pis. 

 16, figs. 18).— \ guide to bee keeping. 



Observations on the large larch sawfly (Nematus erichsoni) with sug- 

 gestions for remedial and preventive treatment in infested larch woods,
