doubt that seeds containing holes made by this beetle are unfit for planting, 

 as, even with perfect germination, the opportunity for the entrance of water 

 into the seeds stimulates decay and the seed frequently rots before germination." 



The natural enemies of this weevil include 3 hymenopterous parasites, iiigalphus 

 pallipscs, 8. thoraciciis, and Chremijlus ruhiginosus, first recorded by J. Curtis in 

 England in 1863, and the predaceous mite Pcdiculoides ventricosus, which was 

 observed in Sacramento in 1911. Experiments reiwrted show that 140° F. is the 

 lowest temperature at which all of the weevils are sure to be killed and that 

 the germinative power of the bean is not seriously injured until the temperature 

 reaches 160° or over. " Fumigation with bisulphid of carbon, at the I'ate of 

 about 2 or 3 lbs. of the chemical to each 1,000 cu. ft. of air space for 48 hours, 

 is a perfect remedy in an air-tight receptacle, as in the case of other bean and 

 pea weevils." Directions are given for the construction of a fumigator.

Keeping- native bees in Paraguay, A. de Winkelkied Bektoni {Rev. Agron. 

 y Bol. Estuc. Agron. Puerto Bcrtoni, 4 ilDlO), No. 8, pp. 21-2Jf; aJ}s. in Internat. 

 Inst. Agr. [72omc], Bui. Bur. Agr. Intel, and Plant Diseases, 2 {1911), No.^8-10, 

 pp. 2258, 2259). — The author, who has made several attempts to domesticate the 

 native bees of Paraguay, obtained several successful results. The species reared 

 belong to the genera Melipona, Lestrimellita, and Trigoua. These bees are said 

 to yield a more aromatic honey and higher priced wax than does the common 

 honeybee. The bees of the genus Melipona are docile to domestication but are 

 attacked by a dipterous parasite. 



The behavior of Prospaltella berlesei in Italy, A. Berlese {Redia, 7 {1911), 

 No: 2, pp. Jt36-.'iGl ; ahs. in Internat. Inst. Agr. [Rome], Bui. Bur. Agr. Intel, 

 and Plant Diseases, 3 {1912), No. 3, p. 831). — The author, who introduced and 

 has been conducting investigations relative to the value of P. berlesei in com- 

 bating Aulacaspis {Diaspis) pentagona, finds that it adapts itself perfectly to 

 the climate of upper Italy and is not injured by even the most intense winter 

 cold. This parasite reproduces very readily in the regions where the winter 

 is less lengthy and milder, as in Genoa and environs of the Garda Lake, and 

 more slowly in the regions with severe winter as in Piedmont, where it probably 

 goes through one or two generations less than in the hotter parts. 



Parasitic enemies of the Mediterranean flour moth (Ephestia kiiehniella), 

 W. W. Frocoatt {Agr. aa.~. N. S. Wales, 2-3 {1912), No. J,, pp. SOl-SU, figs. 2).— 

 A new parasite, described by Cameron as Amorphota ephestia, has been found to 

 parasitize the Meili terra noan flour moth in Victoria and New South Wales. 

 "The parasites confine their attention to the many flour moth caterpillars that 

 crawl out and; pupate in the dust, flour, and rubbish on the walls and open 

 places. They can not. or will not, enter the closed places, so that while the 

 parasites have a considerable value in any mill infected with the Mediterranean 

 flour moth when they destroy all the outside caterpillars, they also have their 

 limitations, as they never make their way into the places where the main body 

 of the caterpillars are feeding and pupating." Four specimens of Bracon 

 {Iladrohracon) hrhctor were bred from waste flour received from flour mills. 



A hymenopterous parasite of Ixodes, R. du Buysson {Arch. Par., 15 {1912), 

 No. 2, pp. 2Ji6, 2^1, fig. 1). — Ixodiphagits caucurtei, reared from many Ixodes 

 nymphs collected on deer at Chautilly, Department of Oise, France, in October 

 and at Fontainebleau in November is described as new to science. The species 

 is closely related to I. texanus. 



The zoocecids of North Africa, C. Houard {Ann. Soc. Ent. France, 81 {1912),
