report the author carries out the apparent intention of his predecessor. Doctor Lug- 

 ger, in publishing a monograph on the diptera of M innesota. Brief aotes are given 

 in a preliminary statement on the special features of. insect outbreaks during the j ear. 

 The Hessian fly and chinch bug occurred in much smaller numbers than ordinarily. 

 Alfalfa was greatly injured by the red-legged grasshopper. Various other species of 

 insects caused damage, particularly cotton) maj le scale, stalk borer, cotton boll- worm 

 in corn, white grubs, etc. 



As already indicated, the major pari of the report is occupied with a monograph 

 on the diptera of Minnesota. The author describes in considerable detail the biology 

 and anatomy of this order of insects, and presents notes on the habits, life history, 

 and means of combating all known injurious Hies in the State, together with short 



accounts of other diptera not of economic importance. The families which the author 



discussed include among others the Tipulidse, ( lulicidse, < Ihir imidse, ( iecidomyidae, 



Simuliidse, Syrphidae, Oscinidse, ( >estridae, Sarcophagidae, Muscidse, Hippoboscidse, etc.
