ANOPHELES PUNCTIPENNIS 1013 



Pupa (plate 150, fig. 709). — Cephalothoracic mass subpyriform, the hairs 

 small and few ; air-tubes short, funnel-shaped, notched on one side. Abdomen 

 stout, thick, the distal segments depressed; hairs abundant but short, each 

 segment with a short stout pointed spine at apical angles ; anal paddles long, 

 with a terminal seta. 



Egg (plate 147, figs. 693, 694 *).-— Elongate fusiform, reticulate ventrally, 

 finely granular dorsally ; floats large, extending nearly to apices, closely approxi- 

 mated medianly on dorsal surface, arcuately produced at sides to apical fourths, 

 widely separated on ventral surface and showing only on middle third of sides. 



The eggs are laid singly or in small groups upon the surface of water. The 

 larvae are found in aU sorts of water in ground-pools and streams and occasion- 

 ally in artificial receptacles. The larvae are found all the season, breeding being 

 continuous until winter. The larvae occur most commonly in swamps containing 

 algae, but also in springs along the edges of streams and in rain puddles or even 

 artificial receptacles. Where very abundant they occur in almost any water. 

 Larvae have been found repeatedly and in numbers in rain-puddles, the water 

 muddy and without trace of algal growth ; rearings from these larvas gave ex- 

 clusively A. punctipennis. Associated with this species, the larvae of A. quad- 

 rimaculatus frequently occur, although usually in distinctly lesser numbers. 

 Jordan and Heiferan, in Michigan, found that the two species segregated accord- 

 ing to character of breeding-places, spring-fed pools being inhabited exclusively 

 by Anopheles punctipennis, while in the river, only a few feet away, the other 

 species was abundant. The females bite at dusk, seldom by day, and they are 

 less aggressive than other species. The female hibernates. Mr. Knab has 

 observed the mating habits of the adults and his description of them will be 

 found in the first volume, pages 136-138, of this work.
