Front of the head dark yellow. Eyes large, and situated near together. Thorax dirty green. Abdomen round; and in some appears to have been of a yellow, in others of a blue, colour. Wings reticulated and transparent; the superior (being narrowest) have only a small dark spot on the anterior edge of each near the extremity; all the remaining part being transparent. The inferior have also a small dark spot on each, like the superior; but close to the abdominal edge they have a large dark {118}cloud on each, which reaches from the anterior edge almost to the posterior. At this part the wings are much broader than is generally observed in any of this genus; gradually widening from the extremity to the abdominal edge. AGRION VIRGINICA. Plate XLVIII. fig. 2. ORDER: Neuroptera. SECTION: Subulicornes. FAMILY: Libellulidæ, _Leach_. GENUS. AGRION, _Fabr._ Libellula, _Linn._ Calepteryx, _Leach_. AGRION VIRGINICA. Aureo-viridis, abdomine nigro, alis fusco-luteis apice nigricantibus, stigmate ([female]) albo. (Expans. Alar. 2 unc. 9 lin.) SYN. Libellula virgo var. Gamma, _Drury, App. vol._ 2. (Exclus. Syn. _Linn._) HABITAT: Virginia. Head beautiful golden green. Eyes round, black, not so large as those in the other figures, and placed at a distance from each other. Thorax golden green. Abdomen black, long, and slender. Legs black, very spinose. Wings reticulated, and of a fine shining brown, somewhat inclining to dark blue, with a remarkable white oval spot near the tips of each, which part is much darker than the rest; but in the males is the same, the wings there being of a deep mazarine blue, almost black, and without the white spots. Drury observes of this insect, that "it is somewhat like one we have in England, but distinctly different, and soon to be discovered by comparing them together." He nevertheless applied to it the name of the English species, which I have been consequently obliged to reject. LIBELLULA BERENICE. Plate XLVIII. fig. 3. ORDER: Neuroptera. SECTION: Subulicornes.
