Flint (W. P.). An Egg Parasite of the Army-worm (Heliophila 

 unijyunda). — Jl. Econ. Entom., Concord, ix, no, 3, June 1916, 

 p. 377. 



A severe outbreak of Cirphis {Heliophila) unipuncta (army-worm) 

 occurred in southern and central Illinois during the spring of 1914, 

 Adults of the first generation were abundant in June, but hardly any 

 moths of the second generation were seen during the end of June and 

 July, The same conditions were observed during the following year. 

 Investigation of eggs kept in captivity showed the presence of a 

 Chalcid parasite, a species of Telenomus, which was responsible 

 for the destruction of 79 per cent, of the eggs,

 in New Jersey. — Jl. Econ. Entom., Concord, ix, no. 3, June 1916, 

 p. 378, 



A female specimen of Gonepteryx rhamni, L., was obtained from 

 Cotoneaster microphylla imported from France. Castnia therapon, 

 KolL, was found in the rhizomes of greenhouse orchids, causing con- 

 siderable damage. The host plants were obtained originally from 

 Pernambuco and were probably infested at the time of arrival. This 

 moth is a native of Brazil, where the larva feeds on Oncidimn 

 crispum and Catasetum sp. 



McCray (A. H.). Report of the Finding of American Foulbrood and 

 European Foulbrood in the same Bee Comb. — Jl. Econ. Entom., 

 Concord, ix, no. 3, June 1916, p. 379. 



The presence of American and European foulbrood in the same 

 comb was detected in a sample received from Stanislaus County, 

 Cahfornia. The former was recognised by the typical scales adhering 

 to the lower cell wall, by the spores of Bacillus larvae, and by the 

 characteristic odour, the latter by the grey, yellow and brown colora- 

 tion of the larvae and by the presence of B. pluton. Spores of B. alvei 

 were also found.

To control bark-beetles in fruit trees, the author injected carbon 

 bisulphide into the holes, which were then closed with wooden plugs. 

 The trees were then painted with whitewash containing 10 per cent, of 

 carbohneum, and manured with liquid manure. The result was 

 completely successful. 



Chambers (F.). A Defence against Weevils, — Rhodesia Agric. JL, 

 Salisbury, xiii, no. 3, June 1916, pp. 397-398. 



A native method of protecting maize against weevils consists of 

 mixing the grain with finely powdered wood ashes before storing and 

 afterwards coating the outside of the sacks with fresh cow dung. 

 A layer of wood ashes on the outside of the sacks only is very effective. 

 In an editorial note it is stated that a layer of building lime on the 

 floor of the storing place and between the successive layers of bags 

 also gives satisfactory results.
