light has a special attraction for gravid females it seems difficult to 

 determine. 



As to the bite, that is much like that of sollicitans and, like that 

 species, taeniorliynchus takes no long thought in reaching a proper 

 spot ; any exposed place will answer and it has the same ankle-seeking 

 propensity that its allies have. I have never taken it indoors, even along 

 shore. 



The egg laying habits are like those of sollicitans and the eggs them- 

 selves have not been found separable from those of its ally. In fact in 

 my first experiments I bred more taeniorliynchus than I did sollicitans 

 from the egg-filled sods collected. 



DESCRIPTION OF THE LARVA 



Scarcely distinguishable from A. sollicitans in outline and color, and 

 breeds in same pools. Seven to eight mm. (.28-32 inch) long to end of 

 ninth segment, dirty gray or yellowish, head one and one-half times as 

 broad as long and usually pale yellow; sides and front shaded with 

 brown; sometimes sides of vertex bisymmetrically marked. Faint 

 crescent-shaped mark, with black spot in advance and four others to 

 rear usually present, though one or more, or occasionally all, are com- 

 monly absent. On front of head four single hairs from individual pits, 

 each pair separated laterally. Small tuft of four or five hairs at base 

 of each antenna. Antenna short and slender, with only slight reverse 

 curve, apical half dark, light yellowish toward base ; surface with small 

 scattered spines. Tuft situated on shaft at about middle, has two or 

 three moderate sized hairs ; apex has few short bristles and one longer 

 one, besides small joint. Rotary mouth brushes have central hairs 

 pectinated at tip. Mandible and maxillary palpus similar to sollici- 

 tans, palpus shaped a little differently, with long apical tuft. Mentum 

 triangular, ten or twelve teeth on each side of apex, very little vari- 

 ation in form, differences chiefly in curve at sides. 



Thorax wider than long, transversely depressed on dorsal surface, 

 lateral hair tufts short, two very small tufts near anterior margin. 



Abdominal segments normal, four or five short hairs to lateral tuft 

 in anterior two segments, fewer in posterior. Eighth segment has small 

 lateral patches of from sixteen to twenty-two oval scales. 



Anal siphon grayish about one and one-half times as long as broad. 

 Two rows of spines, from twelve to sixteen in each row, extend beyond 

 middle with a small terminating tuft. Spines of moderate length, be- 

 coming short toward base and peculiar by being toothed on both sides. 

 The ninth segment square or broader than long, with hairs of double
