[October 
the ferruginous basal patches are cliaracteristic of ur.mla. Except for the latter 
] should unhesitatingly say it was a suffused form of archippus. Taken at Sherborn, 
hlass., by the late A. L. Babcock in 1895 and presented to me by A. P. Morse. There 
is in the Academy of Arts and Sciences, Brooklyn, N. Y., a similar specimen taken 
by Ernest Shoemaker at Washington, D. C. 
All of the above diiirnals are in my collection. 
L., Ursula var. alhojasciata new. (Plate II, figs. 7 and 8). A dimorphic form of Ursula hav- 
ing a mesial white band, of varying width, extending across all the wings from near the middle 
of the costa to the inner margin of the hind wings about one-third the distance from the anal 
angle and reappearing on the under surface. Outside the white band, on the upper .side of the 
secondaries, there is a row of light blue spots sometimes merging into a continuous streak. 
These are replaced below by the usual ferruginous spots of Ursula. There is very little, if any, 
red on the secondaries above as on the arthemis cj’ . 
Habitat, so far as reported, Mass., eastern N. Y., and vicinity of Jersey City. 
Types, 2 c? c? and 2 $ 9 in my collection. 
Co-types Ic? and 19, Maseum of Comparative Zoology, Cambridge, Mass., 
and 1 9, collection of Henry Wormsbacher. 
This variety is readily ilistinguishable from the species it closely resendtles, 
L. arthemis Drury, by one familiar with both insects. On fresh specimens the ground 
color of the wings above in the basal area has a very different tone. On Ursula and 
its varieties there is a bluish cast while on arthemis the same dark or nearly black 
region has a brownish hue. Other points to be considered are size, habitat, width 
and position of the wdiite band, the amount and shade of the blue on the secondaries 
above and as before indicated the presence or absence of red on males. 
Proserpina Edw. is generally conceded to be a variety of arthemis (a view which 
I take), although some writers have suggested that it might be a hybrid with Ursula. 
The strongest argument to support this theory is the fact that the ranges of the two 
species overlap. No such claim can be made with regard to alhojasciata, however, 
as it has been taken in localities where arthemis is unknown, such as Staten Island, 
Long Island, N. Y., and Jersey City. It has also been taken near Boston. Has 
arthemisl It seems very doubtful. All the recorded captures I have been able to 
trace have turned out to be albofasciata. There are several such specimens in the 
Museum of Comparative Zoology at Caml.)ridge — one from Maklen, another from 
Wollaston, etc., wrongly identified as arthemis. We must, then, revise our records. 
If albofasciata is a sport we should expect to find intergrades; and we do find 
them in abundance, from those having the merest trace of a white band across the
