the agTicultnrist of tlie station, gives a six-page illustrated account of 

 Melanotus communis and Agriotes mancus, compiled mainly from Prof. 

 Comstock's account of these species. Of the wire- worms damaging 

 wheat the present spring- in Garfield County, Mr. Scobey identifies 

 90 per cent as belonging' to the former species and 10 per cent to the 

 latter. We doubt the specific accuracy of these determinations, since 

 up to the present time neither of these species has been found in the 

 State of Washington. 



Some Live-stock Pests in Louisiana.— lu the report of the veterinarian of 

 the Louisiana Agricultural Experiment Station for 1891 some attention 

 is paid to the Horse-bot Fly, Screw- worm Fly, and to the Ox Warble. 

 The notes are prepared from the remedial standpoint, and contain no new 

 facts regarding the life-history. For the Horse Bot it is recommended 

 to attend to the general health and condition of the animal by thor- 

 ough grooming and cleanliness, and by improving his ajjpetite and 

 digestion by the use of some mineral or vegetable tonic, such as gentian, 

 ginger, cinchona bark, or some of the salts of iron. Under the head of 

 the Screw-worm Fly an interesting case is given, in which the Screw- 

 worms rendered valuable assistance in removing a morbid growth in a 

 hoof crack of a mule brought to the infirmary of the station for treat- 

 ment. The worms removed the growth completely, and the veterina- 

 rian then removed the worms. Nothing is recommended for the Ox 

 Warble except the application of tobacco juice and a two per-cent solu- 

 tion of carbolic acid, to prevent the deposition of the eggs. 



Bulletin 30 of the South Dakota Station.— Messrs. I. H. Orcutt, Ento- 

 mologist, and J. M. Aldrich, Assistant Entomologist, have just pubUshed 

 atwenty-pagebulletiu, in which the newinsectary is described, and short 

 articles are given upon jiarasites of the large Willow Saw-fly; the food 

 habits of the Striped Gopher ; applying poison to potatoes; beekeep- 

 ing; soapsuds for cabbage lice; kerosene emulsion for lice on stock and 

 for sheep scab; a cheap spraying pump, and general recommendations. 

 Four Hymenopterous parasites are mentioned as affecting Cimheoe 

 americana, viz: Cryptus nuncius, Opheltes glaucopterus^ lAmneria ferru- 

 gineipes^ and Mesochoms melleus. Four Dipterous insects are also men- 

 tioned as parasites, viz, one species of Sarcophaga and three of Phora. 

 These, however, in our opinion, should not be considered as true para- 

 sites. The authors have concluded that a large proportion of the food 

 of the Striped Gopher {S2)ermo2)Mli(s 13-Uneatns) consists of insects, and 

 these are almost exclusively of injurious species, including principally 

 cut- worms, web-worms and caterpillars. The authors advise the use of 

 strong soapsuds ujdou cabbage for plant-lice in iireference to kerosene 

 emulsion, as they have found that a weak solution of the latter substance
