Vol. Xxiv] ENTOMOLOGICAL NEWS. 29 



Those who make use of the Entomological Literature will 

 notice a few changes which the compilers thought to be ad- 

 vantageous. Beginning with this issue, papers treating of the 

 Arachnida and Myriopoda will be included, and further, the 

 papers of a purely or partially systematic nature will be group- 

 ed separately at the end of their respective classes civ orders. 

 These changes, we hope, will be to the advantage of those who 

 have use for this section of our journal.

ENTOMOLOGICAL GLEANINGS FROM ALL QUARTERS 

 OF THE GLOBE. 



Color of Hemiptera. 



The bright coloration of most Hemiptera is due to a fatty tissue 

 known as pseudovitellus, and this tissue invades the developing egg 

 at an early stage of maturation. . . . Dr. Buchner, "Studien an 

 intracellularen Symbionten" (part i., Archiv f. Protistenkunde, vol. 

 xxvi, 1912), has taken up the detailed study of the range and nature 

 of this form of symbiosis, and he gives a very interesting and well- 

 illustrated account of his recherches. (Nature, Oct. 17, 1912, p. 197.) 



The Insects' Homer. 



Under the heading of the "Insects' Homer" Mr. Maurice Maeter- 

 linck directs attention in the September issue of The Fortnightly Reviezi^ 

 to a little-known work by J. H. Fabre, in ten volumes, entitled "Sou- 

 venirs entomologiques." ... In these volumes, from which copius 

 extracts are given, Fabre recorded the results of fifty years of obser- 

 vations, study and experiment on a number of insects, including wasps 

 and wild bees, certain gnats, flies, beetles, and caterpillars.

Caterpillars and the Weather. 



[The Entomologist of the Utah Agricultural College Experiment 

 Station, Mr. E. G. Titus, sends the copy of the following letter re- 

 ceived in his Station correspondence.] 



"l Nov. 1912. I would like to know if in your opinion the presence 

 of a very unusual number of caterpillars this fall has any bearing on 

 the weather, either past or future. 



We have had a cold and wet spring and an early and wet fall here 

 this year. Do you think the presence of caterpillars is beneficial or 

 detrimental to the soil? G. M."
