The army worm in Rhode Island, C. O. Flagg and G. W. Field (Rhode Inland 

 Sta. Rpt. 1S96, pp, 319-326, fig. 1). — Twenty-eight replies received in response to a 

 circular showed that the army worm was present and doing more or less damage in 

 5 counties. The crops reported damaged were oats in 9 cases, barley 5, Hungarian 

 grass 4, corn 3, and grass 2. Hungarian grass sown late was reported as entirely 

 destroyed. A brief account of the life history of the insect is given and the follow- 

 ing destructive agencies noted : Robin, bluebird, blackbird, bobolink, meadow lark, 

 pigeon woodpecker (Colaptes auratus), a black predaceous ground beetle, Tachina 

 and Ichneumon Hies, spiders' webs, electric lights, and a large ground spider (Epeira) 

 that feeds on caterpillars. It is also noted that the insects seemed to be attacked by 

 an infectious disease that carried them oft' in great numbers. To these natural 

 checks the rapid disappearance of the pest is attributed. 



The preventive measure noted is the ordinary one of furrowing and the use of 

 lines of tar.

 1897, pp. 233-258, pis. 2, figs. 8). —A. reprint of Bulletin 133 of the station (E. S. R.,.9, 

 p. 365). 



Some of the injurious insects of Pennsylvania, C. W. Johnson (Pennsylvania

 peruiciosus), the cotton maple scale (Pulvinaria innumeraMlis) , the rose scale (Diaspis 

 rosw), the bag or basket worm ( Thyridopteryx ephemerceformis), the white marked 

 tussock moth {Noiolophns [Orgyia~\ leucostigma), the oak carpenter worm or borer 

 (PrionoTtjstus rohinios), locust borer (Cyllene robinio'), the broad uecked prion us 

 (Prionus laticollis), stag beetles (Lncanns dama), May beetles (Lachnosterna spp.), 

 rose beetle (Macrodactylus subsplnosnx), asparagus beetle (Crioceris asparagi), the new 

 asparagus beetle (Crioceris 1 .'-punctata), the fruit bark hectic (Scolytus rugulosus), the 

 hickory bark borer (Scolytus 4-spinosus), the pine bark beetle ( Tomieus cacograpluis), 

 the potato stalk borer (Trichobaris trinoiata), the thick thigh ed walking stick 

 (IHapheromerafemorata), as well as the remedies against each. 



A chapter is given on the subject of sparing the insectivorous birds, and on impris- 

 oning and lining the snarer. 



Contributions from the New Mexico Biological Station No. 2 on a collec- 

 tion of Diptera from the lowlands of the Rio Nantla in the State of Vera 

 Cruz, II, C. H. T. Townsend (Ann. Mag. Xat. His., 6. ser., 20 (1897), 117. pp. 

 172-291). — This paper takes up the Trichopoda, some 22 species and varieties of 

 which are tabularly distinguished, and the new varieties, T. histrio indivisa and 

 T. lanipes tropicalis and the new species T. phatiana described. The last is distin- 

 guished by its wings, being black only on the costal third, and by its black abdomen 

 with two basal yellow spots. 



Pennapoda is described as a new subgenus which is distinguished by the abdomen 

 being nearly of the same shape in both sexes, rounded at the tip and narrowed 

 slightly at the base. It is connected with Trichopoda proper by the forms of 

 T. histrio. 



A new variety of Lipoptena depressa of the Hippoboscida>, namely, L. mexicana, is 

 also described. X. depressa breeds at times and probably always on deer, and the 

 author thinks it is always wingless.
