air but keeping close to the water along the shore line or fluttering un- 
seen between the stems of the sedges.”

These are damselflies of moderate size and rather unique coloration. 
The bright yellow of the rear of the thorax beneath will at once dis- 
tinguish them from all the others. The legs are rather long but their 
spines are short. 
The nymphs (Ndm. ’03, p. 247) are climbers amid the submerged 
vegetation of sheltered pools. The gills are long and rather narrow 
and rather aburptly tapered at their tips. 
There is but one species. 
301. Chromagrion conditum Hagen 
Hag. ’76, p. 1805: Mtk. Cat. p. 67: Garm. 717, p. 565 and ’27, p. 46. 
Length 35 mm. Expanse 48 mm. Me. and N. J. toInd. and Que. 
These are damselflies of blue and yellow coloration. The face is pale, cross 
striped with black on postclypeus and base of labrum. Top of head black. Front 
of thorax is well covered by a broad black stripe that is widest in the middle and 
notched each side above. The sides are pale with only traces of stripes in the 
depths of the sutures; yellow below the third lateral suture (or higher in the 
female); becoming a robin’s egg blue above. Legs blackish externally on the 
femora and internally on the tibiae, becoming pruinose white basally, as in the 
whole under surface of the thorax. Wings hyaline with rather long quadrangular 
stigma surmounting a single cell. Abdomen blackish above with the blue of the 
yellow of the sides, on its basal half, extending upward almost to the middorsal 
line at the front of the segments. 6 and 7 wholly black; 8 and 9 in the male with 
a dorsal pair of round spots on a blue ground, and an intervening, interrupted 
middorsal blue line. Appendages black. 
The imagoes appear to keep rather close to the shelter of their native 
pool, spending but little time on the wing. Transformation takes place 
for the most part in the morning or early forenoon, and the place 
selected is but a few inches above the water. The species is of wide 
distribution, but is every where quite local. 
70. TELEALLAGMA KENNEDY 
(Kndy. ’20, p. 87 for Telagrion daeckit) 
These are very long and slender and pale-hued damselflies in which 
the wings are stalked, generally as far out as the anal crossing. Within 
our range is found a single species. 
The nymph (Ndm. ’04, p. 715) is likewise elongate, but otherwise 
similar to Enallagma.
