Notes on remedies for cuttcorms (pp. 628-635). — Cutworms are dis- 

 cussed in their relation to the onion crop. The treatment found effec- 

 tual was dried bran or middlings mixed with Paris green at the rate of 

 1 lb. of the latter to 50 of bran or 30 of middlings. Experiments were 

 also made with Paris green added to resin-lime mixture, used as a spray. 

 It was found to be more or less ineffectual. Relative to the amount of 

 damage done, the highest noted is 99 per cent. The life history and 

 habits are briefly touched upon and the belief expressed that the eggs 

 of the insects are deposited later in the fall than is generally supposed, 

 and that they do not hatch until the following spring. 



Entomological section, H. Osborn and E. D. Ball {Iowa Sta. Bpt. 

 1896-97, pp. 112-125, pis. 5).— The author briefly notes that the army 

 worm did not occur in injurious numbers during 1897, an outbreak of 

 the Hessian fly in the northwestern part of the State, plums as being 

 in some cases seriously affected with plant lice, and the appearance of 

 the San Jose scale in the State, and considers the life histories of leaf 

 hoppers the principal subject of investigation during the year. The 

 three species noted as affecting garden crops are Agallia punctata, A. 

 novella, and A. sanguinolenta. Referring to the genus generally, the 

 author states that — 



" The species are very difficult of separation and little has been published in 

 regard to their food habits or life histories. During the past seasou the three fol- 

 lowing species have been under observation and their larva? and the general facts of 

 their life histories determined. In order to correctly determine the species under 

 observation, as well as those sent in from other States for determination, a systematic 

 study.of the genus was undertaken, the complete results of which will be published 

 elsewhere. The genus was found to be separable into three groups, of which the 

 three species treated are typical illustrations as far as structural characteristics of 

 the adults are concerned, and the known facts in regard to the larvte and life histo- 

 ries of the other species indicate that they, too, will be found to be very similar 

 within the groups. In general, the species were found to be widely and generally 

 distributed and subject to little variation except in depth of color. The three 

 species treated, though by no means limited to that area, are all that are now 

 known to occur in the northern and eastern part of the United States, while in the 

 Southern States constricta replaces 4 punctata and extends along the Atlantic coast to 

 New York, but it is in the Southwestern States and down into Central America that 

 the majority of the species occur. The species are all single brooded, in northern 

 latitudes at least, and the larva? agree in feeding on stems near the ground and 

 hiding under rubbish." 



The first species, A. punctata, appears to be naturally an inhabitant 

 of shady woods, feeding upon various species of Oompositae, Cruci- 

 ferae Cheuipodiaca*, etc. Its taste for horse-radish, cabbage, spinach, ' 

 and sugar beets gives it economic importance. The remedy recom- 

 mended is kerosene emulsion spray. 



The second species is merely described. The third is noted as pre- 

 ferring open sunny localities and occurring in great abundance in most 

 all places except damp and shady woods. Clovers, especially white 

 clover, a large number of weeds, and sugar beets are objects of its 

 attacks.
