 various plants in hot-houses in England and Belgium, and also with 

 H. haemorrhoidalis on bananas in Spain; H. patter soni on Granadilla 

 leaves in the Gold Coast ; H. m inntissimus on violets in India ;

RoARK (R. C). Plants used as Insecticides. — Amer. Jl. Pharmacy, 

 Philadelphia, xci, nos. 1 & 2, January and February, 1919, pp. 

 25-37 and 91-107. 



This annotated list, representing 135 genera, calls attention to 

 promising insecticidal plants for further investigations. The desir- 

 ability of finding new insecticides is pointed out, especially as the 

 present prices of arsenicals, pyrethrum, etc., are so high. The majority 

 of the plants listed probably have no commercial value at present, and 

 many are troublesome or dangerous weeds, and if they could be used for 

 insecticidal purposes, a market would be found for material that is at 

 present valueless or even the cause of direct loss, e.g., from stock 

 poisoning. 



It is stated that tons of roots of Veratrum viride are used annually in 

 preparing hellebore, and that during the fiscal year 1916-17 more than 

 £40,000 worth of the flowers of Chrysanthemum cinerariaefolium were 

 imported into the United States. 



Baker (A. C). Fitch's Thorn Leaf Aphis.— Proc. Biol. Soc. Washing- 

 ton, D. C, xxxii, no. 37, 30th September 1919, pp. 185-186. 

 The mention of Aphis crataegifoliae, Fitch [see this Review, Ser. A, vi' 

 pp. 212, 420] has resulted in many enquiries by entomologists in regard 

 to this name and that of A. brevis, Sanderson. Recent comparisons 

 show that A. brevis is a synonym of A. crataegifoliae, which is a distinct 

 species from A. bakeri, Cow. A. crataegifoliae should further be placed 

 in the genus Anuraphis, as also its close relative A. bakeri, both these 

 species living on rosaceous plants and migrating to clover during the 

 summer.
