on the field experiments will be published later. In the cage experiments 70 

 per cent of the weevils present were destroyed by applying powdered arsenate 

 of lead just before the squares were formed, at the rate of 1% pounds per 

 acre. The use of this substance also proved cheaper and more effective than 

 Paris Green in controlling the cotton caterpillar, Alabama argillacea. The 

 circular sets forth that the application of poison can be considered as only 

 one of the methods of controlling the boll weevil. The results secured should 

 be of great value to the cotton planters of Louisiana and the South.

The Mound-Building Prairie Ant, by T. J. Headlee and George 

 A. Dean. Kansas Agricultural Experiment Station Bui. 154, 1908, 

 p. 165-80. 



This bulletin makes substantial additions to our knowledge of the life his- 

 tory and habits of this ant, Pogonomyrmex occidentalis Cress., a species 

 which has proved of some economic importance because of its injuries to 

 grain fields and also on account of the annoyance Inflicted upon man and 

 domestic animals. Experiments have resulted in perfecting a modification of 

 the usual treatment with carbon Insulfid, in that an inverted tub is used to 

 confine the volatile insecticide. There are a number of excellent illustrations, 

 but unfortunately they and the general appearance of an otherwise most ex- 

 cellent bulletin are somewhat marred by the illustrations being on a poor 

 grade of paper.

State Crop Pest Commission of Louisiana, Second Biennial Re- 

 port of the Secretary for the years 1906-1907, by Wilmon New- 

 ell, 1908. p. 1-31. 



This summarized account of two years' work shows that much has been 

 accomplished. The major portion of the time has been given to the study 

 of the more important pests, such as the cattle tick, boll weevil, white fly 

 and Argentine ant. Nursery inspection is another very important line of 

 work. The report shows that the entomologist has at his disposal the ser- 

 vices of five assistant entomologists, in addition to a clerical staff. These 

 men, in cooperation with the United States Department of Agriculture, have 

 done much toward bettering entomological conditions in the southern states. 

 The report, together with the fourteen circulars bound therewith, as an 

 appendix, are well printed, excellently illustrated and most ((immendahle on 

 account of the clear, succinct style.

A Record of Results from Rearings and Dissections of Tachi- 

 nidae, by Charles H. T. Townsend, U. S. Dept. Agric, Bur. Ent. 

 Tec-h. S. 12, Prt. 6. 1908, p. 95-118. 



This bulletin is an extremely important addition to our knowledge of the 

 Tachinidae, a compact group which many entomologists have tacitly assumed 

 to possess much similarity in habit. Mr. Townsend's investigations show 

 such to be very far from the case. A most striking result is his confirmation
