Prof. H. A. Surface also writes that he has seen this insect abundant 

 in IlHnois. 



Iowa.- — Prof. H. F. Wickham writes: "About the distribution of 

 Stomoxys calcitrans, I have no formal notes, but it is very common 

 here, though perhaps less so than during my ])oyhood when little 

 care was taken in the disposition of refuse." 



Prof. 0. A. Johannsen has also observed it personally at State Center, 

 Iowa. 



Kansas. — Bishopp ^ refers to this species as a pest of more or less 

 importance every year in the grain belt of this state. 



Kentucky. — Garman ^ speaks of Stomoxys calcitrans as extremely 

 abundant at St. Vincent, Ky., during August, 1895, and observed 

 the flies very commonly at Lexington, Ky., as late as October 20, 

 1890, sunning themselves in great numbers on the sides of buildings. 



Maine. ^ — Prof. 0. A. Johannsen writes that the stable fly occurs at 

 Orono. Me., where he has observed it personally. 



Maryland. — Mr. S. N. Cory has kindly furnished the following 

 notes on the occurrence of the stable fly in Maryland: "It is abun- 

 dant in this state where we have bred it from horse- and hog-manure. 

 In 1908 it was the species most abundantly bred out in the insectary 

 from this material collected late in the fall. 



Massachusetts. — Extensive observations, particularly in the eastern 

 portion of the state have revealed an abundance and seasonal dis- 

 tribution similar to that which exists in most of our other northern 

 states. The adults do not appear in noticeable numbers until the 

 early part of June. They are then to be seen very generally in locali- 

 ties where there are many domestic animals, but not in sufficient 

 numbers to annoy cattle or horses to any extent. At this time also 

 they are much more local in occurrence, for they do not appear to 

 wander far from barns, stables and pastured animals. In another 

 month they have increased greatly in numbers and begin to appear 

 quite generally in places quite removed from such animals, while 

 horses and cattle are considerably annoyed by them. During August 

 there is a still greater increase in their numbers, and it is during this 

 month that animals are most severely bitten by them. At this time 

 they can be seen in abundance almost anywhere, although as before 

 they are most numerous in places where they can find large animals 

 upon which to feed. During September they are scarcely less abun- 

 dant, until the latter part of the month when they become much 

 less active and are to be seen almost entirely on fences and walls.
