coast. It occurs along- tho Now Jersey coast, the Long 

 Island coast, along Staten Island, at Virginia summer 

 resorts, and at Tybee Island, Ga., and Ht. Augustine 

 and Charlotte Harbor, Fla. Curiously enougli, Dr. A. D. 

 Hopkins states that what is probably this same species 

 apparently breeds in AVest Virginia in pools and small 

 streams fed from coal-mine drainage, the water of which 

 contains a large jiercentage of sulphate of iron. 



There is no doubt that this Culex breeds in great num- 

 bers in the pools left by the highest tides, which subse- 

 quently become freshened to some extent by rains or by 

 the entrance of spring water. It has been caught, how- 

 ever, considerable distances inland, and the question 

 arises, has it been carried to such spots by trains only, 

 or will it breed after being so carried for at least one or 

 two generations in fresh water? Mr. Benjamin S. Pas- 

 chall, of Newfield, N. J., caught this species in August, 

 1900, in his garden. They could be found anywhere in 

 the long grass, practically by the thousands. Newfield 

 has one of the highest altitudes in South Jersey, being 

 about 130 feet above the tide and over thirty miles from 

 the sea. In Mr. Paschall's opinion, the si)ecies must 

 breed there. There had been no wind for a long time 

 before their appearance and the microscope showed all 

 specimens to be freshly hatched. On Seiitember •4th, he 

 tried an experiment and placed a pail of water in a spot 

 where these insects were thickest. By the end of a week 

 he had procured many eggs, and September 14th he 

 succeeded in hatching out several hundred mosquitoes, 

 but not one single specimen of noUicitans; all were ^>?//j-
