MEASUREMENTS.—Males form A, 22-73 mm.; males form B, 36, | 
46 mm.; females, 18-53 mm.; ovig. females, 42-56 mm.; juvs., 9-18 © 
mm. 
Remarks.—Form A males have a relatively long ultimate segment 
of the male abdomen (almost as long as penultimate) with sides 
straight rather than concave (fig. 26a). In form B the ultimate 
abdominal segment is shorter (about four-fifths the length of penulti- 
mate) with sides markedly concave (fig. 26c). In this concavity it 
resembles T. foresti, but this species is distinguished by the broader, 
distally swollen penultimate segment, and the more elongate ultimate 
segment (fig. 26d).
