 9 and 10 of tlie last volume. He also exposes the fallacy of tlie state- 

 ment that Tveeviled peas can be detected by throwing the seed into 

 water. The note upon the oat weevil is especially interesting, al- 

 though the author states that the insect shows a greater preference for 

 a wild grass {Pamciun criis-galU) than for oats. He does not anticipate 

 that it will ever become a serious pest. This species and Entomoscelis 

 adonidis are here mentioned for the first time as injuring cultivated 

 crops in this country. The latter is a ckcumpolar species, common to 

 northern Europe and Asia, and occurs in Montana and Utah, as well 

 as in the Northwest Territories and Manitoba. It was also destructive 

 during the past season to radishes and cabbages. 



"Wheat Insects in Maryland — Prof. Dorau has iDublished. as indicated 

 in our foot-note,=* a short illustrated account of the insects noticed as 

 damaging the grain of wheat during his residence at the Maryland 

 Agricultural College. The species treated are the Angoumois Grain- 

 moth [GelecMa cerealeUa), the Eed G-rain-beetle [Silvamis cassice), the 

 Lesser Grain-beetle {S. siinnamensis), and the ''Black Weevil" {Calan- 

 dra oryzce)^ the latter being more commonly known as the Eice Weevil. 

 Prof. Doran has experimented with remedies against the Angoumois 

 Grain-moth and finds that naphthaline is an admirable preventive. It 

 acts more slowly than bisulphide of carbon, but its effects are more 

 lasting. Bisulphide of carbon is recommended for the beetles, but in 

 the only test made, the germination of wheat "was apparently affected 

 unfavorably " by the treatment. An interesting observation on the 

 rise in temperatui^e of middlings infested hy SUvamis casske is men- 

 tioned, but the details of this cimous fact will be given in fall in Xo.

The American Bot-flies -whose Larvae live in the Skin of Man.t — In a recent 

 paper bearing this title Dr. Blanchard has given us a most valuable 

 critical summary of the literature of the subject. He quotes verbatim 

 the x)ertinent accounts of thirty-one authors, ranging from He La Con- 

 damine, 1749, to GonneUe, 1889 ; compares carefully all of the larval 

 descriptions, reproducing nearly all figiu-es ever published, and arrives 

 at the conclusion that four distinct species have been found infesting 

 man.
