\ During the month 18,064 parasites of fruit-flies were reared, and! 

 21,730 parasites of the horn-fly, house-fly and stable-fly were liberated. I 

 The breeding of Paraleptomastix abnormis, a parasite of the mealy bug, 

 was continued.

 trator of the Northern Territory of Australia for the eighteen 

 months ended 30th June 1915. pp. 43-46 of Administrator's 

 Report for the year 1914-15. — [Sine loco.] 1915, 2 plates. 

 [Received 9th March 1916.] 



The following insect pests are noted in this report : — Earias 

 huegeli, Rog. (boll worm) and Dysdercus cingulatus, F. (red cotton bug) 

 on cotton ; several scale-insects, including LepidosapJies beckii 

 {Mytilaspis citricola), Chrysomphalus aurantii {Aspidiotus coccineus), 

 C. aonidum (A.ficm), and Parhtoria ziziphus, on citrus trees, Aspidiotus 

 destructor and C. aonidum on coconut palms, and A. orientalis on 

 papaws. The last-named species appears to be spreading rapidly in 

 spite of the abundance of predaceous Coccinellids. 



Experiments in the control of termites showed that arsenic in some 

 form is the cheapest and most effective substance to use for the 

 protection of timber.

 in Connection with Cranberries. — Massachusetts Agric. Expt. Sta.,

 [Received 9th March 1916.] 



During 1913 there was a marked decrease in the numbers of both 

 Rhopobota vacciniana, Pack, (flowed-bog fire-woim) and Mineola 

 vaccina, Riley (cranberry fruit worm), but Epelis truncataria var. 

 faxonii, Minot (cranberry span-worm), and various species of cutworms 

 were unusually abundant. It was noticeable that winter flooding 

 produced very shght mortality among the pupae of this species, 

 which has also been found feeding on the bearberry. A small 

 Trypetid was reared from cranberries which has been identified as a 

 small variety of the apple maggot [Rhagoletis pomonella, Walsh). 



The following parasites were reared from cranberry pests, as well 

 as some which appear to be new to science : — The Tachinid, Exorista 

 pyste, Walk., and the Ichneumons, Phyiodietus vulgaris, Cress., 

 and Pimpla conquisitor. Say, from Peronea minuta, Rob. ; the 

 Braconids, Phaneroioma tibialis, Hal., and Microbracon dorsator, Say, 

 from Mineola vaccinii ; Ichneumon extremitatis, Cress., and the 

 Tachinid, Euphorocera claripennis, Macq., from Cyrmxtophora sulphurea, 

 Pack. ; Winthemia quadripustulata, F., from Xylina (Calocampa) 

 nupera, Lintner ; and Tachina robusta, Town. These parasites, and 

 especially those of R. vacciniana., are very liable to destruction during 

 the flooding of the bogs [see this Review, Ser. A, iii, p. 532]. Phanerotoma 

 tibialis was by far the most important parasite of M. vaccinii. Berries 

 from the dry bog produced three times as many parasites in proportion 

 to fruit- worms as did the berries from the flooded bog. The time of 

 greatest emergence of the parasites was between 30th June and 9th 

 July. A study of the control of M. vaccinii in flooded bogs showed that
