hold responsible. The remedies proposed are gathering; windfalls and 

 removing the surface earth under the infested trees. Another inter- 

 estuig article treats of the occurrence of one of the common mites {Ty- 

 roglyphus longlor) in great numbers in hay in stacks and Avhen stored 

 in lofts. Considerable attention is given to the use of l*aris green 

 against leaf-eating orchard caterpillars, and the advisability of mixing 

 Koftsoap with Paris green is considered at some lengtli. The ccmclu- 

 vsion reached is that a\ liatever arsenic is set free in the soap solution is 

 neutralized by the free alkali of the soap, but the mixture as a whole 

 is a tenacious, sticky mass, Avhich it is difficult to pi'operly dissolve in 

 water. The bulk of the report is occupied with a consideration of the 

 Diamond-back Moth {Plutella cruci/erarum) which, as we have already 

 stated, occurred in enormous numbers in certain parts of England last 

 summer. The article includes a great deal of interesting correspond- 

 ence with a number of Miss Ormerod's intelligent co-workers. Last 

 year's occurrence of this species was a very exceptional one, and accord- 

 ing to Miss Ormerod seems to have been due rather to the fact that moths 

 were borne in on easterly winds in the spring rather than that they bred 

 where first noticed. The remedies are those mentioned by Mr. White- 

 Lead, whose paper we reviewed in the last number of Insect Life. 



Bulletin No. 5 of the New Mexico Station.*— Mr. C. H. Tyler Townsend 

 is the author of a brief bulletin just received which treats of the Vine 

 Leaf-hopper, the Codling Moth, the Green June-beetle {AUorhina so- 

 brina), and Eoot-borers (Larvi« of Prionus spp.). He finds that the 

 kerosene emulsion is the only ijractical remedy for the Vine Leaf-hop- 

 per, and that it should be apijlied early in the season and directed 

 against the under sides of the leaves. After the insects have acquired 

 wings it is too late to do effective work. The Codling Moth, it seems, 

 has just been found for the first time in the Mesilla Valley, although it 

 has occurred abundantly in other portions of New Mexico for some 

 time. The Allorhiua here mentioned has previously been referred to 

 by the author in the current volume of Insect Life (p. 25) as A. nitida. 



A Bulletin on Spraying.— The Department has just published, as "Far- 

 mers' Bulletin Xo. 7," a short consideration of spraying fruits for insect 

 pests and fungous diseases, with a special consideration of the subject 

 in relation to the public health. This bulletin puts the reasons for 

 spraying and the best formula in condensed shape for the use of the 

 practical fruit-grower.
