pools. In a])i)oarance it is rather sliort and thick-set, the l)reathing 

 tube is stout, about two and one-lialf times as long as broad, and 

 almost black in color. The spines on the tul^e are curved and 

 slender, and bear from two to three teeth at the base and are thirteen 

 to eighteen in a row. The scales on the eighth abdominal segment 

 are spatulate in shape and bear a long spine at the tip and a row of 

 small spines on each side. They are placed in two irregular rows. 

 We ha\e taken the adults of this species at Uni^'ersity Farm, 

 June 23, 19U), and at Fergus Falls. August 21, 1912. Apparently it 

 is widely distributed throtigh the State. 



Anopheles punctipennis Say. — The Mottled-Winged Anopheles. 



This Anopheles is fairly common in many i)arts of Minnesota. 

 In the autumn of I'U? adults entered winter quarters in the base- 

 ment of the Insectary building at the University Farm, but the 

 severe winter seemed to kill them, for they could not be found 

 toward spring. On August 20, 1*'13. larvae were found in the 

 shallow margins of a large swamp at Savage, Minnesota. Again 

 in July. l'H5. larvae were fotuid in large numbers in the lagoon 

 in Langford Park, St. Paul, and in swamps near the University 

 Farm. In the former place they were above large masses of algae 

 in three or four feet of water. Except on this one occasion we 

 have always found them in shallow water at the edges of swamps 

 among water plants and often where there was considerable decay- 

 ing i)lant material in the water. The species has an extensive 

 range, being reported from New Jersey and New York south to 

 Texas, west to Oregon, and north to Canada. The adults may 

 become quite numerous, but rarely so as to become a serious 

 annoyance. 



The adult can be (|uickly distinguished from the other Minne- 

 sota anophelinc by the somewhat smaller size; wings more densely 

 clothed with darker scales, giving it a gray or blackish appearance ; 

 large yellowish sjiot near the apical fourth of the wing on the 

 cephalic margin and a second yellow s]:)ot on the extreme apical 

 margin. 



The larva differs from the ordinary culicine larva by lacking 

 the long breathing tul)e. It lies parallel to the surface of the water 

 and close to the surface him instead of hanging downward at a sharp 

 angle to the surface. The body is usually mottled with brown or 

 grey in such a way as to make it hard to distinguish. Often the 

 Screen alsrae taken in as food show through the bodv, adding to
