LIBELLULA LYDIA.

Plate XLVII. fig. 4.

Order: Neuroptera. Section: Subulicornes. Family: LibellulidÆ, Leach.

Genus. Libellula, Linn. &c.

Libellula Lydia. SubÆnea, abdomine (?) coeruleo lateribus luteis, alis hyalinis, singul strig parv basali fasciÂque lat transvers pone medium, fusco-chalybeis. (Expans. Alar. 2 unc. 9 lin.)

Syn. Libellula Lydia, Drury, App. vol. 2.

Habitat: Virginia.

Front of the head green. Eyes dark brown, very large, and placed near each other. Thorax green, having on each side two transverse yellow stripes. Abdomen of the male blue, with small yellow indented marks on the sides; that of the female yellow; the former having two little horny substances like tails at the extremity, which are wanting in the female. Wings reticulated and transparent; the middle of each being of a very dark blue colour, occupying about a third part, and crossing them from the anterior to the posterior edges, which by the reflection of white paper becomes dark brown. A dark brown stripe also, about a quarter of an inch in length, issues from the base of each wing, almost joining to the anterior edge; below which the males have a white patch placed on their inferior wings.

ÆSHNA JUNIA.

Plate XLVII. fig. 5.

Order: Neuroptera. Section: Subulicornes. Family: LibellulidÆ, Leach.

Genus. Æshna, Fabr. Libellula, Linn. &c.

Æshna Junia. Fuscescens, unicolor (in vivis virescens?), alis hyalinis, cost pallidÈ infuscatÂ, stigmate oblongo, nigro. (Expans. Alar. 4 unc. 3 lin.)

Syn. Libellula Junia, Drury, App. vol. 2.

Habitat: New York.

Head large, and in front of a brown yellow. Eyes brown, almost black, large, and placed close together. Thorax, when the insect was living, apparently green. The abdomen is now brown, but was probably green also; for these kind of insects are very subject to lose the gay colours they exhibited when alive. Wings reticulated and transparent, appearing of a brownish colour along the anterior edges; having a small slender black stripe, about a quarter of an inch long, placed thereon near the tips, and a small angular white spot at the base of each next the body.

"This insect is very much like one we have in England, but not entirely so, differing in some circumstances from ours; and is introduced rather as a subject for illustrating the history of these insects, than as a specimen meriting a place in this work."—Drury.
