The collection here reported upon was identified and descriptions of ;ne\v forms written several months ago, completion of the report being delayed by lack of time to trace out a few loose ends. As a new revision of the genus Erythroneura is under way it is thought best to put on record now these Illinois data. The Eupterygidae were long a favorite group with the late Charles A. Hart, who substantially assisted Gillette's revision (Proc. U. S. Nat. Mus. 20, 1898, pp. 750-773) with loans of material. He had sorted subsequent collections of the State Natural History Survey and had invented manuscript names for most of the undescribed forms. A number of these were independently named in the Key to the Nearctic Species and Varieties of Erythroneura (Trans, Am. Ent. Soc, 46, pp. •267-321, August, 1920) by the writer, who did not have Hart's material at hand at the time. Some of the others are here described and the writer is glad to adopt Hart's MS. names for three of them, namely liinata, ociilata and rnfomaculata. Many of the specimens of more recent date here recorded were collected by J. R. Malloch, and some of an inter- mediate period by J. D. Hood. Many records here given are the first since the original description of the forms involved. Genus Erythroxeura Fitch E. vulnerata var. vulnerata Fitch, red form.—Urbana, Jan. 11, 1908, Nov. 11, 1915; St. Joseph, Sept. 3, 1916; No. 25069; also Brownsville.

Erytiironeur.^ oculata, new species In outline as seen from above this species resembles £, vulnerata Fitch, the shape of the vertex being nearly the same ; the venation how- ever is as in my Group 2 (i. e. like that of E. obliqiuu Say). The ground color of the present species is pale greenish yellow, and the mf)st distinc- tive markings are: a jiair of rountl velvety black spots on the upi)er part of face near eyes, and a similar pair, closer together on vcrte.x just hack of apex; there are also four dark spots in a transverse row on anterior 40 disk of pronotiim, a spot on each anterior angle back of eye and a falcate vitta near middle of each lateral margin ; the basal triangles of scutellum are velvety black. There are no other dark markings above, but the apical cells and clearer parts of corium especially the long cells between the sectors are chiefly dusky fumose. Red markings are present as fol- lows: a broad, anteriorly convex lunate vitta on middle of pronotum, 3 blotches on each clavus, the middle one largest, "2 blotches between third sector and claval suture, and 2 short lines on second sector ; the wings are dusky fumose. Color below smoky-brown, a pale-yellow area about each velvety black spot on face and a top-shaped pale area on middle of front; antennae and legs pale yellowish. Length 3 mm. Holotype, 9 .

Color of head and thorax above, pale yellow ; sctitellum with basal triangles nearly black : tegmen with dusky streaks which occupy nearly all of its surface except inner base of clavus, base of corium. most of costa and distal parts of 3rd and -tth apical cells.

State Nat. Hist. Survey.) Erythroneura lunata, new species Belongs to Group 4 of my Key, having the vertex without dots and more pointed than in E. tecta and diverging greatly in coloration from any of the other species. Ground color somewhat opaque whitish, more or less tinged with reddish throughout and with the following distinct pinkish-red markings : fine irrorations tending to be grouped in a trans- verse band between anterior angles of eyes, and a short posterior median vitta on head, a spot in each anterior angle, more or less of front margin, and a median vitta on pronotum ; four posteriorly oblique red streaks from costa of tegmen, one at front of corium, one at each end of costal plaque and one more or less ramose overlying cross-veins. The scutellum has the base narrowly, the basal triangles, and apex dusky to black, and there are two triangular markings on middle of clavus, and two elongate [wsteriorly directed markings on the corii just outside these, dusky to black, that form when tegmina are folded a broken posteriorly open semi- circle ; a dusky band extends from hind edge of costal plaque to radial margin, leaving costa and most of the exceptionally long first apical cell clear ; this band is interrupted near radial margin by the paler veins ; first apical cell with a dark dot near apex, second nearly filled by a dusky mark- ing; fourth dusky at base. Face with an irregular cross-band and short median vitta reddish; genitalia tipped with black, and dorsum of abdomen with two broad dusky vittae. Length 3 mm.

Erythroneura comes var. reflecta, new varietv Much like E. comes var. rubra Gillette in connection with which it was mentioned in my Key, but the pale markings are more extensive, and the red ones instead of being a solid jasper-red as in that form are dilute bluish-red with carmine edgings ; the fact that all of the red vittae are of this compound character gives the variety the appearance of having the most complex pattern of any of the comes varieties.
