192 DRAGONFLIES OF NORTH AMERICA 
home in brooks flowing through the bushy open woods or through deep woods, 
provided the stream is wide enough to admit the sunlight. 
They fly over the brook and alight in the grass occasionally, but are usually 
balanced over the pools, as wary as hawks, requiring a very swift swing of the 
net and a sure aim. 
155. Somatochlora walshi Scudder 
Scud. ’66, p. 217: Mtk. Cat. p. 183: Walk. ’25, p. 55: Garm. ’27, p. 223. 
Length 47 mm. Expanse 66 mm. Alta. and Mich. to Que., Me. and N. Y. 
Face brownish yellow with black labrum and black markings on the post- 
clypeus and front of frons. Vertex black. Occiput brownish or black. Thorax 
brassy green. Lateral pale stripes sometimes obscured; the first long and straight, 
the second rather ovoid. Legs streaked with reddish brown. Wings hyaline with 
an amber tinge, darker about the bases. Second abdominal segment yellow on 
sides, the paired lateral spots sometimes confluent and continuous with the apical 
annulus; segment 3 with dorsal and ventral lateral spots anteriorly, and pos- 
teriorly with lateral pale streaks; 5, 6 and 7 with small lateral spots; 8 and 9 
sometimes with incomplete apical annuli; 10 black, sometimes with a dorsal 
yellowish spot. 
This species inhabits the small quiet streams of boggy places. Walker 
reports it flying very actively in all parts of the marsh but particularly 
on the main channel. They flew on the average about waist high, 
poising frequently in the air with the abdomen slightly flexed, but dart- 
ing back and forth very rapidly and dodging the net well.
