ENTOMOLOGY. 1067 



figs. 4). — The article contains a notice of the unusual ravages of this 

 insect in 1898, together with notes on the life history, habits, natural 

 enemies, and approved artificial remedies, and a synoptic table for the 

 determination of the larvae of the species of Xotolophus. 



Apple-tree tent caterpillar (GUsiocampa americana) (pp. 177-190, figs. 

 3). — A resume is given of the food plants, habits, and distribution of 

 the insect, and an account of the well-known remedies for controlling it. 



Forest tent caterpillar (Clisiocampa disstria) (pp. 191-201, figs. 2). — 

 The insect is said to have been unusually destructive to forest and fruit 

 trees iu Xew York State for the past 2 years. The food plants and 

 natural enemies of the insect are given and the usual remedies 

 recommended. 



Zebra caterpillar (Mamestra picta) (pp. 201-207, fig. 1). — This insect 

 is reported as having caused great destruction to timothy hay and oats. 

 A description of the insect is given, together with notes on the natural 

 enemies and the remedies to be recommended. 



Xylina antennata (pp. 207-213, fig. 1). — The caterpillar of this insect 

 is recorded as feeding on soft maples, upon which it was very injurious. 

 A good description of the insect is added. The author reared from the 

 insect a parasite tachina fly ( Winthemia 4-pustulata). As remedies he 

 recommends spraying with the arsenites, or "many of the descending 

 caterpillars can be killed by inclosing the trunks of the infested trees 

 with a low, overhanging barricade and then treating the collected 

 larvae with hot water." 



The author records biological and economic notes on the following 

 insects: Lecanium tuUpiferw, Lepisma domestica, Eurypelma hentzii, 

 Eriocampoides limacina, Silvanus surinamensis, Elaphidion rillosum, 

 Galerucella hiteola, G. cavicollis, an elm-leaf miner, Lecanium armenia- 

 cum, L. cerasifex, and the San Jose scale. 



Under the caption "Hints about insecticides," the author gives a 

 general account of the substances used for destroying insects and the 

 rationale of spraying. 



The report is supplemented with a list of the publications of the 

 entomologist for the year and an exhaustive index. 



Report of the entomologist, A.D.Hopkins (West Virginia Sta. 

 Rpt. 1897, pp. 42-57).— The special lines of work carried on by the 

 author are reviewed, and attention is called to certain of the more 

 important features. Special study was made of the scolytid family of 

 beetles, which family contains the most destructive and dangerous 

 enemies of forest and shade trees, as well as of fruit trees, and one 

 of the worst enemies of the red clover. The collection of these insects 

 made under the author's supervision is said to be one of the most com- 

 plete in existence. 



The series of experiments begun in 1895 to determine the best time 

 to fell timber have been continued and some remarkable results have 

 been obtained, but the author states that in order to verify them and
