The name Phyllophaga, proposed by T. W. Harris in 1826, is adopted 

 by the author on the ground that its validity was fully estabhshed by 

 its publication in connection with a series of valid specific names, viz., 

 quercina, hirsuta, hirticida, balia, etc. In the absence of a designated 

 genotype, the species hirticida, Knoch, is proposed as the type of the 

 genus. The name Lachnosterna, used both by English and American 

 entomologists, was not put forward by Hope until 1837. A list of 

 North American species of this genus, with their synonyms, is given, 

 together with a bibliography containing the names of 32 papers giving 

 original descriptions of the species occurring in the United States and 

 Canada. 



A new species which is abundant in southern Illinois in June, July, 

 and August is described under the name P.forbesi.

 Provinces. — Dominion of Canada Dept. Agric, Entcm. Branch,.

The most important species of cutworms occurring in the Prairie 

 Provinces are Euxoa ochrogaster (red-backed cutworm) and Porosagrotis 

 orthogonia (pale western cutworm), while Euxoa (Chorizagrotis) anxiliaris 

 (army cutworm) is found in restricted areas. The eggs of the first two 

 species are deposited in August and September below or on the surface of 

 summer fallow land which has become broken and partly covered 

 with weeds. A few larvae hatch out in autumn, feed for a short time, 

 then enter the ground to hibernate. The majority of larvae emerge 

 in the following April. Owing to the dry nature of the soil, the larvae 

 are able to move freely below the surface and feed almost entirely in 

 this position on the stems of weeds and crops. Pupation takes place 

 in earthen cells during June, and adults appear about a month later. 

 Control measures are based to a large extent on methods of cultivation. 

 Fallow land should be kept free from weeds during the oviposition 

 period, i.e., from 1st August to 20th September, and should be worked 

 as finely as possible. If this measure is not carried out, deep autumn 

 ploughing should be performed. Autumn wheat should not be sown 

 earlier than the second week in September. A poisoned bait con- 

 sisting of 50 lb. shorts, 1 lb. Paris green, 1 gal. molasses and 1| gals. 

 water may be scattered during April or May among crops which have 

 been planted on fallow land. Where the soil is dry, the land should 

 be harrowed after application. Measures of control which are not 

 suitable for prairie conditions are the use of light traps, the application 

 of lime and salt and the burning of stubble in autumn.
