change. The real estate agent talks about new land, ''where no old 

 bugs have reared their little buglets," but the settler must class his 

 statement with the other fiction propagated by the promoter. Even 

 the one-time desert, has its insect life, and weeds spring up to replace 

 the sage, even if the settler is careful not to introduce the worst 

 varieties. The persistent Russian thistle rolls for miles across the 

 plains and distributes its seed, and, use all the care you may, the 

 insect pests soon follow the production of crops and planting of trees. 

 I have wondered what desert plants the Leaf-cutter bees used to 

 line their tunnels before the coming of the settler with trees, but have 

 not been able to find their former upholstering materials. ARTHUR J. 

 SNYDER, Springfield, Idaho.

Under the above head it is intended to note papers received at the Academy of 

 Natural Sciences of Philadelphia pertaining to the Entomology, excluding Araci- 

 hida and Myripoda, of the Americas (North and South). Articles irrelevant to 

 American entomology, unless treating of new genera, will not be noted. Contri- 

 butions to anatomy, physiology and embryology of insects, however, whether re- 

 lating to American or exotic species, will be recorded. The numbers in heavyfaced 

 type refer to the journals, as numbered in the following list, in which the papers 

 are published, and are all dated 1909, unless otherwise noted.
