OF WASHINGTON. 141 



able size in partly cleared woods and, as usual, from nearly 

 every kind of water examined, but in no great abundance. 



Anopheles maculipennis Meig. 



This species was rare. Curiously enough, all the larvae found 

 were alike and of a peculiar, striking coloration. They were at 

 once separable from punctipennis by being black with a straight, 

 narrow, white dorsal line, furcate on thorax. The white-spotted 

 punctipennis were never marked w r ith such a uniform line. 



Culex canadensis Theob. 



Very common at first, gradually decreasing in numbers, but 

 continuing all summer. Larvae occurred in a cold spring-pool 

 in woods late in June, but they were not abundant, apparently 

 most having completed their transformations. Others were taken 

 in road-side puddles. A few stragglers occurred till the middle 

 of July, but after that few more were found. Eggs were ob 

 tained from females confined in jars; I did not find them in 

 nature, though larvae in the first stage were several times collec 

 ted. The eggs are probably laid in places where water is liable 

 to collect, or in pools. In the latter case they sink and would be 

 very difficult to find. The eggs from the females in jars were 

 kept in water. One hatched immediately, two more in about a 

 week, and another in two* weeks, but most of them remain un- 

 hatched yet, apparently hibernating. They are laid singly. 



Culex reptans Meig. 



Perhaps about half as abundant as the preceding species. The 

 occurrence was the same, principally a woodland species and 

 only troublesome about the house at the period of greatest abund 

 ance. No larvae were found, and I think that the species had 

 ceased breeding before June 2Oth, when I arrived. The decline 

 in numbers of the adults was even more marked than with C. 

 canadensis, scarcely any being taken with the net after July 

 i5th, though so common at first. The last ones taken had be 

 come much worn. This is probably a truly single-brooded 

 mosquito with the principal time of flight in June and without 

 the continuous addition of a few fresh specimens as with C. 

 canadensis. The fall and winter are probably passed in the 

 egg stage. I neglected this species, having gotten the idea that 

 it was common, and so failed to secure eggs. 



Culex cantans Meig. 



Rare in my usual collecting ground, a pine woods near the 

 lake, but rather common about two miles distant in the low land 

 between Lake Winnepesaukee and Lake Squam. Only adults 

 were taken and these became much worn as the season advanced. 

 This is another strictly single-brooded species with hibernation 

 in the egg stage. No larvae were seen. Eggs were obtained 

 from females confined in jars, but they all remained unhatched 

 till the present time.
