Melon and Strawberry Pests: Aphis cucumeris and Corimel^jna 

 pulicaria 212 



Plant-lice injuring cantaloupe and cucumber vines in Maryland are 

 probably Aphis cucumeris, 213. How they may be killed by spraying 

 with a rod and Vermorel nozzle, 213. The insect puncturing the 

 blossom stems of the strawberry is probably the ' ' flea-like negro- 

 bug," 213. Figure of the insect, 213. Its numerous food-plants, 213. 

 Cultivation of two favorite food-plants (weeds) recommended as lures, 

 213. Has recently proved destructive to cucurbitaceous vines in New 

 Jersey, 213. Fish oil soap said to be the best remedy for it, 214. 



Scale Insects on Camellia and Oleander 214 



Oleander leaves from Jacksonville, Ala., with supposed fungus 

 attack, show only the oleander scale, Aspidiotus nerii, 214. The scales 

 figured and characterized, with figure of the male insect, 214. Its 

 extensive distribution, 214. The many plants infested by it, 215. 

 Features of the camellia scale, 215. It apparently belongs to Parlatoria, 

 215. Kerosene emulsion and whale-oil soap solution effective against 

 these scales, 215. Kerosene may safely be applied to the underside of 

 infested leaves, 215. 



A Grapevine Scale Insect, Lecanium sp. ? 215 



A scale insect infesting a vine in Springfield, Mass., described, 215. 

 The eggs beneath it described, 215. The species not recognized, 216. 

 A different scale on the same vine is evidently a Lecanium, 216. The 

 newly hatched larva with no cottony secretion, 216. Number of 

 eggs counted beneath one scale, 216. How the scales may be des- 

 troyed, 216. Importance of destroying the eggs, 216. 



Apple-tree Insects of Early Spring 216 



Abundance of insect attacks on apple buds, 216. Can not well be 

 checked if operations against them are deferred, 216. Insects from 

 Lansing, N. Y., 217. The apple-tree aphis identified, and the harm 

 it causes, 217. The apple-tree case-bearer, Coleophora malivorella , 

 217. The second time of its recognition in New York, 217. The life- 

 history in brief and habits and remedy for it, 218. The eye-spotted 

 bud-moth associated with the preceding, 218. Its increase in New 

 York, 218. The apple-leaf Bucculatrix from Malcom, N. Y., 218. 

 May be killed by arsenical spraying, 219. Of insects received from 

 Lincoln, N. Y., a small gray moth frequenting apple-tree in May, is 

 (wrongly) identified as the eye-spotted bud- moth, 219. A "small 

 green louse" occurring on the buds is accepted as the pear-tree Psy 11a, 

 219. It had also been recently received on blossom buds of apples, 

 from Ghent, N. Y., 219. The presence of the insect indicated by the 

 "honey-dew," 220. Its previous occurrence on apple recorded, 220. 

 When and how to attack the Psylla, 220. Subsequent studies have
