THE CANADIAN ENTOMOLOGIST. 65 



I 



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. 



Antennje 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). 



Palpi in length about equal to the diameter of the eyes, clothed with 

 thick, bristly, dark brown hairs, some of which are white tipped ; apical 

 joint short, conical, projecting a little beyond the hairs. 



Locklet black, curving about half way over the eyes. Front of head 

 dark brown. 



Thorax above and beneath clothed with long brown hairs, concolorous 

 with the posterior wings. 



Abdomen darker brown, reaching only to the pale band of the hind 

 wings. 



Legs dark brown ; the posterior pair have the femur and tibia of the 

 same length, bearing brown hairs which nearly equal them in length ; 

 tibiae armed with two pairs of spurs ; tarsi twice as long as the tibiae, 

 moderately spinose. 



Expanse of wings, 1.65 in.; length of body 0.55 in. 



Described from a single female received from Mr. W. H. Edwards. 

 The specimen was captured in Hamilton, Ontario, by Mr. J. Alston 

 Moffat, in 1877, in company with another like it, which escaped capture. 



In the Hesperidse the antennal club afitbrds excellent generic features. 

 It is unfortunate that in this unique specimen, the half of one antenna 

 and the terminal half of the club of the other, have been lost. It being 

 also of the female sex, Ave are without knowledge of the presence of a 

 costal fold in this species. In the absence of these characters, it is 

 referred, with some doubt, to the genus Eudamus, in which Dr. Herrich- 

 Schseffer, Dr. Speyer and others arrange species with rounded hind wings 

 and those in which they are greatly prolonged. Of the three groups in 

 which Dr. Speyer has divided the genus, viz., '''Hind wings on submedian 

 nervure little or not at all produced,— ■''* Prolonged in a lobe, — ***Caud- 

 ated, — E. Eledra falls in the first group. 



The detection of the above species is a very interesting discovery for 

 this portion of the United States.
