hovering, cither, for Mr. Grossbeck found them as vicious as Mr. 

 Brakeley did at Lahaway in former years. Where this aurlfer 

 occurred it was the only species and prohably bred close by, 

 although no breeding place could then be identified as such. The 

 records made by Mr. Brakeley prove that this is one of the single- 

 brooded species, maturing in April, but that the adults may live 

 until midsummer, ready to bite viciously to the end. Mr. Brake- 

 ley's observations further prove that the species does not occur 

 each year in notable numbers, but that in some seasons neither 

 larvae nor adults can be found in places where the year before both 

 were abundant, even where the conditions of moisture are ap- 

 proximately identical. 



"In another section, an open swampy area, C. triviUaius flocked 

 about me while walking, and they l)it readily. Xumbers were dis- 

 turbed in and rose froiii the grass, alighting on the lower part of 

 my clotliing. This is the smallest mosquito that I have ever found 

 in numbers in the field eager to bite, so it attracted attention at 

 once. All the specimens were badly rubbed." This is the earliest 

 record that we have for this species, and indications now point tO' 

 successive broods throughout the summer. That it bites readily is 

 now also established, but thus far no examples have been found in 

 or about dwellings. 



In yet other parts of the woods C. canians were found commonly, 

 and they bit ravenously. The specimens were very nnich worn, as 

 if they had been on the wnng for some time, and it is possible that 

 there may have been an admixture of one of the other species that ' 

 are closely allied in the adult stage. On the porch of the hotel a 

 few aurifer, one canadensis ajid two perkirhons were takeii at dusk, 

 showing that these may become nuisances. 



July 7th, another visit Avas made, this time to the southern end, 

 and with the especial object of determining whether one of the 

 smaller lakes or ponds, on the edge of which a club-house was con- 

 templated, was a mosquito breeder. It was found that it was not ; 

 that the pond had clean edges ; was without shallows or vegetation 

 rising above the surface, and was well stocked with fish. In the 

 woods around about C. cantans was still found in considerable 

 numbers, and there were also found the pot holes, some yet con- 

 taining water, from which these specimens had been bred earlier 

 in the vear. No larvae of any kind were found in the pot holes
