typical sqicaniiger, since they have been so determined by Mr. D. W. 

 Coquillett, and were taken a few miles up the bay from where the original 

 sqiiamige?' was obtained, and which was described by Mr. Coquillett. 



However, it is the habits I wish to speak, about here. Larvae of this 

 species were found without exception in the salt water pools, and almost 

 invariably with Ciirriei, which is a strictly salt-marsh mosquito in this 

 territory. Larvae first appeared on February 20th, and none were seen 

 later than April 20th. Adults from this brood made their way to the hills 

 opposite, and while they were not found to have the migratory habit so 

 well developed as Ciirriei, which was observed to migrate ten miles, they 

 were found at least three or four miles from their breeding ground. No 

 adults were seen to emerge after March 25th, due to our control work, and 

 none were found flying about on the marsh after the middle of May, 

 although adults were found in the hills u]) to July 2nd. We may infer, 

 therefore, that the maximum adult life may be three months, and this agrees 

 with the New Jersey observations. It was found there, however, tliat the 

 species is single brooded, but in 1904 a brood was observed to emerge on 

 the San Francisco Bay marsh in September, making at least two in this 

 section, but, of course, climatic conditions may explain this difference. 



Negative evidence points to the fact that this species passes the v,^inter 



in the t^g stage, the eggs hatching as already mentioned, very early in tlie 



following season. Since the adults were seen in the hills nearly two months 



after their disappearance on the marsh, it is evident that at least the 



majority do not make their way back to the marsh for egg-laying. Of 

 those that migrated, three or four were found with eggs early in the season, 

 but the great majority had no eggs developed. Further evidence, however, 

 is necessary to establish or disprove the fact that the migratory forms are 

 barren. Besides Cjilex Ciirriei., this is the only marsh species found in 

 this territory, and because of the fact that it is fewer brooded it is not so 

 abundant.
