Article II. — Notes on a Collection of Erythroneura and Hvmetta 

 (Eit[>tcr\gkl(ic) chiefly from Illinois, ivith Descriptions of Nezv Forms. 

 By W. L. McAtee. 



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.

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
