{105}EUPTILON ORNATUM. Plate XLVI. fig. 2. ORDER: Neuroptera. SECTION: Filicornes. FAMILY: Myrmeleonidæ, _Leach_. GENUS. EUPTILON, _Westw. Gen. Nov._ Hemerobius, _Linn. Drury._ EUPTILON ORNATUM. Viride, thoracis puncto antico abdomineque lineâ dorsali nigris, alis hyalinis venis numerosissimis, strigisque duabus obliquis obscuris. (Expans. Alar. circ. 3 unc.) SYN. Hemerobius ornatus, _Drury, App. vol._ 2. HABITAT: Dinwiddie, in Virginia. Head dark green. Antennæ pectinated or combed. Eyes black. Thorax dark green, with a black patch next the head. Abdomen dark green, with small rings of yellow, and a small black line running along the upper side from the thorax to the extremity. Wings membranaceous and pellucid, or transparent, of equal length; the superior ones having two small transverse black stripes placed near their posterior edges, at about half an inch distance from each other. Latreille, in his Genera Crustaceorum et Insectorum, Vol. 3. p. 199, after describing the genus Chauliodes belonging to the family Hemerobiidæ, observes, "Congenerica videntur insecta a Dom. Drury iconibus vivis expressa, tom. 1. Pl. 46. Fig. 2. 3." I have never seen the present species, but from the admirable accuracy of Moses Harris (by whom the figures were drawn) it is evident that the neuration of the wings of this species is identical with that of Myrmeleon, agreeing especially with the insect represented at Fig. 4. of this plate, and exhibiting the irregular longitudinal nerve below the subcostal nerve and the strong furcate nerve running along the middle of the wing; whilst, at the same time, the neuration is quite unlike that of Fig. 3. Hence I have no hesitation in placing this insect in the family Myrmeleonidæ. It however disagrees with the genera of which that family is composed, viz. Myrmeleon, Linn. (Myrmecoleon, Burm.) Ascalaphus, Fabr. and Nymphes, Leach, in having bipectinated antennæ, so that I have been compelled to establish a new genus for its reception. Can it be possible that, according to the not uncommon practice of the time, the specimen had been mended, and that pectinated antennæ had been substituted in the stead of the ordinary ones of a Myrmeleon?
