one (see Howard, Mosquitoes, pp. 83 to 90, and Ent. News, XII, 93, 

 125, 189, 220 and 254), but they were at first incorrectly identified as 

 Culex puns;efis. I am indebted to Prof. Smith for examples of the 

 larvje. The other species were found and bred by myself. 



Aedes smithii Coquilleft. (Plate X, Fig. i.) 



Head rounded, pentagonal, flattened ; eyes very small, round, 

 black ; * mouth brushes large, but not long ; antennae small, slender, 

 the tuft imperceptible, end hairs small ; pale brown, weakly but dis- 

 tinctly and uniformly colored; widest part of the head just behind the 

 eyes, then gradually narrowing to antennse ; colorless, transparent, the 

 thicker parts brownish. Thorax quadrate, a little wider than long, 

 rather squarely angled, the three segments incised roundedly and 

 equal ; lateral hairs long, equal, the anterior and dorsal ones very 

 small. Abdomen slender, submoniliform, segments equal ; lateral 

 hairs long on all the segments, the hairs diminishing in number, but 

 not in length posteriorly; subdorsal tufts short, of three or four hairs. 

 Lateral comb of the eighth segment a single row of stout teeth. Air- 

 tube shorter than two abdominal segments, moderate, narrowed at the 

 tip, with two rows of hairs on the upper and two on the lower aspect. 

 Anal segment short, funnel-shaped, with two large inflated processes 

 as clear as glass, reaching as far as the end of the tube and containing 

 fine tracheal branches ; subdorsal, lateral and subventral tufts of long 

 hair terminally; no ventral brush. 



Larvae from the leaves of the pitcher-plant {^Sarracenia'), New 

 Jersey. 



Culex territans Walker. (Plate X, Fig. 2.) 



Head large, flattened, squarely rounded, broad ; antennte large, 

 long, the tuft at the outer third and well developed ; distinctly white 

 centrally, blackish at base and tip, appearing banded ; eyes black, 

 large, transverse, pointed inwardly; translucent, pale luteous ; mouth 

 broadly brown. In some a shade or distinct black band across vertex 

 of head. Thorax short, wide, at maturity swollen like a thick ring, 

 green or greenish ; abdomen slender, uniform ; anal segment as long 

 as the seventh abdominal, with four slender finger-like processes ; dor- 

 sal paired tuft and ventral brush normal, long ; air-tube very long and 



* In some specimens, a brown-black dotted shade extends from before the eye 

 upward and backward, making the eye look to be transverse.
