Vol. Ill, Mo. 1] INSECT LIFE. [August, 1§90. 



SPECIAL NOTES. 



Index to Vol. II— Date of Publication — We send out with this number 

 the index and table of contents to Volume II. Their preparation was 

 delayed beyond the publication of the final numbers of the last volume 

 by press of other work. In view of the difficulty experienced during 

 the past year in promptly issuing a monthly number, owing to circum- 

 stances beyond control and connected with the very nature of Govern- 

 ment work, we shall revert to the plan originally announced in Vol. I, 

 Xo. 1, of issuing twelve numbers to a volume, with no attempt to pub- 

 lish one for each month, as we have endeavored to in the past. 



Bulletin 22, Division of Entomology — Bulletin 22 of the Division of En- 

 tomology has just been issued from the press. It is entitled "Reports 

 of Observations and Experiments in the Practical Work of the Division," 

 and comprises articles by Messrs. Ooquillett, Webster, Osborn, Koebele, 

 Bruuer, and Miss Murtfeldt, being in the main their reports of observa- 

 tions for the season 1889, omitted from the Annual Eei)ort for want of 

 space. 



Mr. Coquillett reports upon the destruction of the Red Scale of Cali- 

 fornia {Aonidia aurantii) by the use of washes. 



Professor Osborn reports principally upon the leaf-hoppers injuring 

 forage plants, and Professor Webster upon grain insects and certain 

 points connected with the economy of a few well-known pests to other 

 crops. 



Miss Murtfeldt sends in a general report on the insects of Missouri 

 for the season. Mr. Koebele reports upon some injurious California in- 

 sects, and i:>articularly upon the Pacific Slope parasites of the Codling 

 Moth. Professor Bruner treats of insects of the year and begins the 

 consideration of the insects detrimental to tbe growth of young trees 

 on tree claims in Nebraska and other portions of the ATest, an important 

 subject which has not before received treatment.
