338 FIRST ANNUAL REPORT OF THE STATE ENTOMOLOGIST. 



[From the Canadian Entomologist, April, 1881, xiii, pp. 63-65.] 



DESCRIPTION OP A NEW SPECIES OF EUDAMUS. 



EuDAMUS Electra, n. sp. 



Size of small Nisoniad^ Jwvenalis. Primaries narrower than in Endamus 

 Pylades Scudder ? , more rounded on the costa, and more oblique on the hind 

 margin. Secondaries rounded, not prolonged at the anal angle as in E. Pylades^ 

 nor excavated opposite the cell as in most of the Nisoniades. 



General color dark brown, approaching that of E. Pylades ; the fringe con- 

 colorous with the terminal portion of the wings, a little paler at their tips. 



Primaries with eleven transparent white spots, upon which an ordinary lens 

 shows regular rows of small black scales — the spots, as follows : Near the end 

 of the cell (apparently open) are two spots, separated by the cellular fold and 

 extending to the enclosing veins (subdorsal and median) — the upper one twice 

 as large as the lower and prolonged backward superiorly in one or two teeth — 

 the lower one subtriangular in shape ; above and in line with these two, in cell 

 10, is a small elongated spot — the smallest on the wing, while beneath them and 

 in range, in cell 2, extending from vein 2 to vein 3, is the largest spot on the 

 wing, enlarged superiorly and excavated inwardly. Outside of this discal band 

 of four spots, are seven others, bordered by dark brown, and arranged in an ir- 

 regular curve, as follows : in cells 9, 8 and 7, three costo-apical spots, oblique 

 to the costa; outside of these, in cell 6, a spot ; in cell 5, still nearer the margin, 

 another; in cell 4, a little farther removed from the margin, another — these last 

 three subtriangular in shape ; in cell 3, extending from vein to vein, a subquad- 

 rate spot, placed farther from the margin, about equidistant with the lower 

 costo-apical spot ; these seven spots, commencing at the costa and omitting the 

 fifth, show a regular increase in size. Outside of these transparent spots, is a 

 series of obscure dark brown intranervular subterminal spots which merge into 

 the dark brown shade of the margin. Inside of these spots, the wing shows by 

 oblique light a purplish reflection approaching a grape bloom but more vivid, 

 with the exception of the internal margin and two brown bands of the color of 

 the outer margin and posterior wings; the bands extend from the subcostal to 

 the internal vein ; the outer and broader embraces the discal band of transparent 

 spots in its outer margin, and the other crosses the median vein at its inter- 

 section by vein 2 ; a brown shade rests also on the base of the wing. 



Secondaries traversed at about their outer third by a narrow obscure brown 

 band, inside of which the wing is dark brown ; outside of this band, the subter- 

 minal series of brown spots of the primaries is continued. 



Beneath, the purplish reflection of the upper surface appears only at the tip of 

 the wing — the median and basal portions being dark brown, concolorous with 

 the secondaries inside of the paler brown band; the obscure intranervular brown 

 spots of the upper surface are repeated, and continued on the secondaries ; the 

 Lransparent spots are without the lines of brown scales. 



The costal vein of the primaries intersects the costa nearly opposite the end of 

 the cell ; vein 8 reaches the margin at the extreme apex — not below it. 



Antennae about one-half the length of the anterior wings, dark reddish-brown, 

 marked inwardly with white at the joints, expanding rapidly into the club (the 

 terminal half of the club lost).
