Dr. Cooper Curtice ou the Cattle Tick.— We have just received from the 

 author reprints of two papers entitled, respectively, "The Biology of 

 the Cattle Tick " and " Ab(mt (battle Ticks," from the .lournal of Com- 

 parative Medicine and Veterinary Archives, July, 1891, and January, 

 1892. In the first of these papers, which was originally read before the 

 Biological Society of Washington February 3, 1890, Dr. Curtice gives 

 a full account of certain careful observations which lie made while con- 

 nected with the Bureau of Animal Industry of this Department on the 

 life-history of the common Cattle Tick {Ixodea hoeis Kiley) for which he 

 has erected the new genus Boophilus. Dates of egg-laying, hatching, 

 molting, and coupling are given, with careful descriptions of the difter- 

 ent stages. In the second i)aper the life-history of the insect is completed 

 and a careful account of its habits is given. The author shows that 

 cattle should be ke])t in good condition in order to resist the pest, 

 and as an actual aitplication he recommends the kerosene emulsion, 

 which is reported by Dr. Francis, of Texas, as " working to a charm." 

 The author touches briefly upon the supi)Osed connection between the 

 Cattle Tick and the Texas fever, and states that it has been thoroughly 

 demonstrated that the fever may be si)read by these creatures. 



Dr. Curtice on the Ox "Warble.'— We have also received from Dr. Curtice 

 an author's extra of his valuable paper upon the Ox Warble of the 

 United States, an advance item from which we published in Insect 

 Life, Vol. ii, pj). 207-8. In this paper Dr. Curtice announces his "on- 

 chision, that the Ox Warble Fly of the United States is Hypoderma 

 lineata Villers and not Hypoderma bovis Linn., as was formerly sup- 

 posed. In sui>i)ort of the conclusion he adduces the results of his ex- 

 amination of the material in adults from the United States National 

 Museum collection and of a very large series of larva? in the collection 

 of the Bureau of Animal Industry of this Department. lie lias adopted 

 the diagrammatic method of representation of the armature of Hypo- 

 derma larvfe, invented by Brauer, and shows by an original diagram 

 the correspondence of the armature of American larva* with H. lineata 

 and not with H. boris. We have already (A"ol. iii, p. 432,) indicated 

 and confirmed these conclusions in a paper before the Entomological 

 Society of Washington last May, and later before the Society for the 

 I'romotion of Agricultural Science. He reiterates his revolutionary
