580 GEOLOGl^CAL SUEVEY OF THE TERRITORIES. 



Length, 19 millimeters; alar expansion, 42 millimeters; setce (broken), 

 about 12 millimeters. 



Eahitat. — New York, by Osten Sacken. 



This is the female Eph. sp. uov., quoted in Proceed. Ent. Soc. Philad., 

 1863, 177, as resembling jB. Banica of Europe, and by Mr. Eaton in his 

 Monograph 71 as a probable variety of U. myops, a statement refuted by 

 me in Trans. Ent. Soc. Lond., 1873, 393. 



I am now convinced that this female belongs to E. guUulata, Pict. The 

 long anterior feet prove Pictet's specimen to be a male imago ; the 

 other feet and the abdomen are wanting. The colors and the pattern 

 described by Pictet agree well, except the anal part of the fore-wings, 

 nearly hyaline in the described females, faintly spotted in Pictet's type. 

 The bright-yellow anterior feet in Pictet's description and figure (the 

 number of joints is erroneous) represent very well this species, and are 

 not to be seen in any other species. Pictet gives no dimensions, but the 

 figure is without doubt of natural size, the alar expansion 36 millimeters. 

 The locality of the type is not known ; it was presented by Mr. Conlon, 

 and may be, as many other species, communicated by this naturalist from 

 the Western Hemisphere. In my Synopsis 38, 1 supposed U. guUulata to 

 belong probably to E. natata, and Mr. Eaton, Monogr. 69, gives both 

 species as synonymous. The type was not in Pictet's collection ; at least, 

 it is not among the species seen by Mr. Eaton in the collection 

 (Monogr., p. 11). 



The resemblance to E. Banica consists in the yellow-colored abdomen. 

 The wings of E. guUulata are more spotted, the abdomen less so or not at 

 all. The colors of the abdomen feet, setee, and wings are very different 

 from those in E. natata. 



E. natata.

 E. vatata, Hagen, Syn., 39, 4. 

 E. simulans, Hagen, Syn., 38, 2. 

 E. guUulata, Eaton, Monogr., partim. 



Male imago. — Dark-brown ; prothorax each side with a black band ; 

 abdomen brown, above with large, serrated, black spots; set£e pale-brown ; 

 articulations of the basal joints faintly marked with darker rings (partly 

 broken); anterior feet brown; tip of joints darker; femora blackish; 

 the other feet paler brown ; appendages pale-brown, joint 2d and 3d darker 

 on tip; 2d joint arcuated, not twice as long as 3d and 4th together; 4th half 

 the length of 3d; wings hyaline; costal margin rather smoky; most 

 of the transversal veins, except in the hind part of the wing, clouded 

 with black ; several larger quadrangular black spots in the middle of 

 the wing and near to the base; hind-wings with the apical margin 

 smoky ; many transversal veins clouded with black, and several small 

 spots blackish. 



Female imago. — Similar to the male ; thorax brighter brown ; wings 

 hyaline on the costal margin, except on the base, not so strongly clouded 

 T^ith black. 



3Iale and female suMmago. — Colors more dull ; wings grayish; anten- 

 nae black ; setse dark-grayish.
