EXPEEIMENT STATION REPORT. GSr 



-worn ; four were C. sollicitans, very fresh, and two were C. can- 

 tans, very old. 



July 7th, the South Mountain Reservation was dry, no breeding 

 was going- on, the woods mosquitoes were not in evidence, and as 

 it was quite windy, few of any sort were flying. Xine old speci- 

 mens of cantator were taken, and there was no evidence that speci- 

 mens from brood 4 of the salt marsh had yet reached this place. 

 At Springfield everything was dry, and neither wrigglers nor 

 adults were found. 



July 14th, conditions at Springfield had not changed ; at Mill- 

 burn no larvae were found, but a number of fresh C. cantator were 

 taken, evidently recent arrivals from the marsh. At Short Hills 

 the woodland pools were free from larvje and mosquitoes were 

 much less in evidence. At South mountain no larvae were found, 

 but there were fourteen fresh and four old cantator and three fresh 

 sollicitans. The old migration from the salt marsh was almost 

 gone, and fresh specimens had arrived to take its place. 



July 18th, eiglit fresh examples of the house mosquito, C. 

 pipienSj were sent in by Mr. Renwick, the first of the season from 

 that source, and on the 21st Messrs. Brehme and Grossbeck made 

 another joint investigation. There had been frequent rains for 

 some days, and it was believed that conditions for local breeding 

 should be at their best. The Springfield avenue low area at ]\Iill- 

 bnni showed pools in the sireani beds, some with and some without 

 vegetation. In the more open pools C. pipiens, C. sylvestris and a 

 few jamaicensis were breeding, while in those with vegetation C. 

 territans and Anopheles ^vere found. There were plenty of a<lult 

 C. sylvestris near these pools, but none were found elsewhere on 

 the, meadow; they apparently reniained very close to home. The 

 area between ^Tillburn avenue, Morris turnpike and Short Hills 

 road was very wet, as usual, but absolutely no breeding was oIj- 

 served in any part of it. Xot a wriggler of any kind was found, 

 and only a few adults were found flj'ing — all sylvestris. The pot 

 holes in the woods were pretty generally filled with water, but 

 absolutely no wrigglers were found in any of them. Adults were 

 moderately abundant, four of them badly rubbed cantans, one C. 

 trlseriatns and the others all C. sylvestris. The latter gave very 

 little trouble, and was usually content to alight on the clothing, 

 making no attempt to bite. As the last sending from Mr. Renwick 

 was all C. pipiens, and his sendings had been pretty generally
