Head black. Eyes contiguous. Thorax and abdomen black; but when the insect was living, were probably mazarine blue. About three-fifths of the wings, next the body, are of a very dark brown; the remainder being grey, almost transparent, with a small streak on the anterior edges of each, near the tips.

[Illustration] LIBELLULA AXILENA. Plate XLVII. fig. 1. ORDER: Neuroptera. SECTION: Subulicornes. FAMILY: Libellulidæ, _Leach_. GENUS. LIBELLULA, _Auct._ LIBELLULA AXILENA. Capite maculis 5 albis, thoracis dorso lateribusque virescentibus, abdominè luteo dorso fusco; alis albis hyalinis strigâ parvâ subcostali basali, margineque tenui (pone medium) nigris stigmate albo. (Expans. Alar. 3 unc. 6 lin.) SYN. Libellula Lydia, _Drury_, _App. vol._ 2. (nec _vol._ 1. _pl._ 47. _fig._ 1.) HABITAT: Virginia. Mouth white. Eyes contiguous. Antennæ short and small, but distinct and plain when viewed through a microscope. On the back part of the head are situated five white spots. Thorax golden brown at top, the sides being of a pale green. Abdomen black at top, the sides being of a tawny orange; beneath pale green. Wings transparent; each having a very narrow dark brown border, beginning at the middle of the anterior edges and running round the tops, where it ends: a very narrow black streak also is placed near these edges, close to the body, from whence it seems to issue, being about a quarter of an inch in length. Our author having inadvertently applied the same name to this handsome species which he had given to that figured in vol. 1. pl. 47. fig. 1, I have been compelled to give this a new specific denomination.
