Psyche 
[Sept. 
The fifth segment of male is prolonged about as in fla- 
vescens , but not such a broad tip ; the last section of the 
genital prongs is long, but not quite as long as flavescens, 
and without any little spinules ; last section longer than in 
tristis. 
Length of body, 12 mm. ; of fore wing 13 mm. 
Three males from Antrim Co., Mich., 6 July (Dreis- 
bach). 
Type M.C.Z. no. 27719. 
Harrisiola annulipes Hag. 
The head has a broad black mark from occipital line to 
front margin, broken by pale between each hind ocellus 
and the lateral boss and the arms of the Y-mark are rather 
broadly pale. The femora have a broad band across basal 
half and a narrow band at tip, the upper and lower edges 
between are pale. The setae are pale on several basal 
joints. 
The genital prongs are long, the apical section swollen 
at base and then slightly constricted beyond from where 
it tapers to the pointed tip, from above this part is seen 
to be compressed, the preapical part has fairly large spi- 
nules above. In the female the ventral plate is rather 
strongly rounded, on each side is a rounded dark spot and 
the outer half of the marginal part is dark, the preceding 
segment has a dark spot in the middle. 
It is not uncommon in the vicinity of Washington, D. C. 
Also occurs at Easton, Pa., and in Montgomery Co., Pa. 
Type M.C.Z. no. 249. 
Harrisiola tristis Hag. 
This was based on two males from Trenton Falls, New 
York. I have seen no other males like them. The femora 
are dark along upper edge as in marginipes , but the lower 
edge pale; the setae are almost entirely pale; there is 
black between the hind ocelli and bosses. It is a small 
species, and a female from the Delaware Water Gap is of 
the same size and may belong to it, with the femora dark 
above and pale below and pale setae. The last section of 
the genital prongs has the upper edge more strongly
