Giraud, reared from Amjphipyra pyramidea ; R. rugulosus, Nees, 

 reared from Arsilonche alhoi^enosa in England and from Acronycta 

 euphorbiae and A. abscondita on the Continent ; R. praetor, Rein, 

 bred from Smerinthus populi in Suffolk ; R. geniculator, Nees, bred from 

 larva of Arctia villica and Odonestis potatoria in Devon and Arctia 

 caja and Ardornis chrysorrhoea {Porthesia similis) on the' Continent ; 

 R. cantherius, sp. n., a fairly abundant parasite of Semiothisa liturata 

 in the New Forest ; R. circumscriptus, Nees, reared in the New Forest 

 from larvae of Triphaena fimbria, T. pronuba, Calymnia trapezina, 

 Taeniocampa stabilis, etc. ; and Sigalphus pallidipes, Nees, a parasite 

 of Orchestes fagi and 0. quercus in the New Forest, a hyperparasite 

 being frequently reared from its cocoons.

 New York, xxiii, no. 1, January 1920, pp. 18-23, 14 figs. 



The hf e-history of the seventeen-year cicada [Tibicen septemdecimj 

 is reviewed. During the appearance of this pest in 1919 very little 

 damage was caused to fruit trees in Georgia and Long Island. Brood 

 xi is due to appear in 1920 in Connecticut and Rhode Island. Where- 

 ever the pest is expected young and natural tree growth should be 

 cultivated so as to attract the females away from neighbouring fruit 

 trees. Bush fires should especially be guarded against the year before 

 the cicadas are due to appear.

 oryzae, L., als Getreideschadlinge. — [Calandra granaria, L., and 

 C. oryzae, L., as Grain Pests.] — Zeitschr. f. angew. Entom., Berlin, 

 vi, no. 1, September 1919, pp. 1-21, 1 plate. [Received 19th 

 April 1920.] 



The distribution and hfe-histories of Calandra granaria, L., and 

 C. oryzae, L., are discussed. C. oryzae has apparently not become 

 estabUshed in Germany, although numerous infestations by this weevil 

 have been recorded. 



The parasites of C. oryzae include the Chalcids, Pteromalus {Meraporus) 

 calandrae and Meraporus grarninicola. C. granaria is parasitised by 

 Cerocephala formiciformis , C. elegans, Meraporus sp., a Chalcid belong- 

 ing to the genus Dibrachys and a Braconid Chremylus (Penecerus) 

 rubiginosus, Nees. A mite, Tyroglyphus {Aleurobius) farinae , has been 

 found in the breeding jars containing C. granaria. 



The various remedial measures suggested by previous authors are 

 reviewed and the use of hydrocyanic acid gas is advocated.

 1919, pp. 25-60, 13 figs. [Received 19th April 1920.] 



The work of various authors with regard to the biology and control 

 of the Mediterranean flour moth, Ephestia kiihniella, Z., is discussed 

 and the value of hydrocyanic acid gas fumigation as a remedial 

 measure is emphasised.
