and usually found mixed with punctipennis. He had found only 

 one place where it occurred by itself. He also noted that some 

 were green and that they varied all the way from this color to 

 black. Green larvae were usually found in marshes where there 

 was a good deal of surface vegetation or where the larvae were 

 above the surface of submerged leaves. He also found it, in one 

 place, in brackish water, this being the only record of this kind 

 in the United States, though it has been reported breeding in salt 

 ish water in Europe. Culex pipicns larvae, he said, when full 

 grown, will stay under ice as long as eight hours without a chance 

 of coming to the surface. C. canadensis is a woodland species 

 found in cold springs. C. sollicitans is the commonest species 

 in Southern New Jersey, and the only one observed in some locali 

 ties. This species is sometimes carried a distance of at least forty 

 miles from its breeding places. Aedes smithii, he thought, did 

 not bite in New Jersey, though Dr. Howard said that the gentle 

 man who collected it in Florida reported its biting badly. It lays 

 its eggs in the leaves of the pitcher plant as they are just opening 

 and when- no water has yet been deposited. 



Dr. Howard congratulated Dr. Dyar upon his contribution to 

 the life-history of the mosquitoes. He was much interested in 

 the larval differences shown, especially as between the various 

 species of Culex. He alluded to the immense increase in the 

 knowledge of these insects which had recently been gained, and 

 the many important discoveries made during the past few months 

 especially, many of them since the publication of his book on 

 mosquitoes. He spoke of the important generic differences in the 

 mouth-parts ; these were not mentioned by Dr. Dyar, but he 

 thought they would prove useful in a table. Dr. Fernald gave 

 an account of his experience with Corethra larvae. Many hydras 

 were found in the jars where he had them breeding. They seemed 

 to momentarily paralyze the larvae. 



As too short a time remained for the other papers to be read before 

 the hour for adjournment, it was voted that Prof. Smith be invited 

 to continue his remarks on the subject of mosquitoes. Doing so 

 he explained how he knew that C. sollicitans is carried a distance 

 of forty miles. Their appearance at certain places away from the 

 salt water is dependent upon the direction of the wind, and the 

 species has been found at least forty miles from its nearest breed-
