ENALLAGMA 327 
ring on 3; apical half of 4; apical two-thirds of 5; apical three-fourths of 6; almost 
all of 7; a narrow linear spot on each side of 8; dorsum of 10. Colored in general 
very much like hageni. Superior appendages like hageni, but with the tips re- 
curved, and the superiors and inferiors of almost equal length. 
The female cannot yet be distinguished from that of E. hagent.

Morse ’95, p. 274: Howe 717, p. 18: Mtk. Cat. p. 60: Garm. ’27, p. 77. 
Length 26 mm. Expanse 34 mm. Mass. 
A very rare bluet. In absence of specimens in our collection, the following 
description of the male has been taken from the original one by Morse: ‘‘Post- 
ocular spots of moderate size. Middorsal thoracic and humeral dark stripes of 
median width. Abdomen blue with the dorsum black as follows: apical half of 
2, fourth of 3, third of 4, half of 5, three-fourths of 6, all of 7 except an interrupted 
basal ring, a stripe each side on 8, all of 10. Dorsum of 10 emarginate. Superior 
appendages short, one-fourth to one-third as long as side of 10, in side view nearly 
as broad as long, directed caudad or slightly deflexed, sides parallel, apex bluntly 
emarginate..... Inferior appendages nearly twice as long as the superiors.”’ 
The female is unknown.

While no definite record is available of the capture of this species within the 
political bounds of the United States, it is found in the life zones that include 
Florida and the U. S.-Mexican boundary; so it is included here for completeness. 
In color it varies from yellow through orange to blue, and black. Face yellow, 
rear of head black. Postclypeus entirely yellow. Postocular spots separated. 
Prothorax marked as in £. basidens. Abdomen with dorsum of 2 with a horse 
shoe-shaped black mark, 8-9 blue, remainder black. 
The female has the postclypeus mainly black, abdominal segment 2 with a 
wide dorsal band, 8 blue with a dorsal black band, 9 black, 10 black at base only. 
Dr. C. H. Kennedy places this species in a genus by itself, which he 
calls Neoerythromma. 
318. Enallagma laurenti Calvert 
Calv. 719, p. 379: Byers ’27, p. 388. 
Length 36 mm. Expanse 44 mm. Fla. 
A long thin lemon yellow and black damselfly found about ponds in non- 
tropical Florida. Male. Face yellow with vestigial black streaks at the base of 
the labrum and postclypeus. The transverse frontal pale stripe reaches to or a 
little beyond the median ocellus. Base and the first two segments of the antennae 
pale yellow. Vertex black with a pair of yellow spots between the lateral and the 
median ocelli. Pale postocular spots linear joined together by the pale postocellar 
stripe, on the occipital margin of the head, also broadly joined with the pale 
color of the rear of the head, i.e., the occipital and postgeneal region. Prothorax
