762 MOSQUITOES OF NORTH AMERICA 



rounded, wider than long ; hairs abundant, moderate, subdorsal prothoracic ones 

 single. Abdomen moderately long, anterior segments shorter; lateral hairs 

 triple on first segment, double on second and third, single on fourth to sixth ; 

 tracheal tubes rather broad, band-shaped. Air-tube stout, gradually tapered on 

 outer two-thirds, about three and one-half times as long as wide ; pecten reaching 

 three-fourths the length of tube, the teeth beyond basal third widely detached ; 

 single spine long, but little widened at base, smooth or with a short branch ; a 

 long hair-tuft within the pecten near middle of tube ; four other small tufts 

 along the ventral line above the |)ecten; four or five tufts on dorsal sur- 

 face. Lateral comb of eighth segment of few scales in a partly double row; 

 single scale thorn-shaped with pointed base, terminal spinule very stout, the 

 sides fringed with short spinules. Anal segment about as long as wide, the 

 plate dorsal, extending well down the sides ; dorsal tuft a brush and hair on each 

 side ; a small double lateral hair ; ventral brush well developed, extending basally 

 beyond barred area ; anal gills moderate, ensiform, longer than the segment. 



The larvEe develop in the early spring pools from overwintering eggs. There 

 is but a single generation in the year, the females living two or three months in 

 the woods, but not frequenting open places nor houses. The habits are the same 

 as those of the other early spring species, with which this occurs mixed.

The names trichurus and cinereohorenlis, proposed for this species, are simul- 

 taneous, as the respective publications were mailed on the same day, as we learn 

 from the printers. We therefore depend upon the dates printed on the numbers 

 of the publications, and give precedence to the former name.
