generally of the warm brownish grey shade that Mr. Tutt 
describes ; sometimes distinctly banded. I quite agree with him 
that these may be readily separated from 7’. biundularia ; but the 
offspring of the summer brood, which emerge at about the same 
time as these, appear to me to come very much closer to 
T’. biundularia in general appearance; and although the lines 
are, as Mr. Tutt suggests, perhaps not quite so sharply defined 
as in that species and somewhat darker in shade, the similarity 
is so great, even in bred specimens, that this character could 
hardly be relied upon, much less so in examples that had flown. 
The ova of 7’. biwndularia are deposited from the middle to the 
end of May; the larve are not full-fed until the end of July, when 
they descend to the surface of the earth, and remain in pupe until 
the following May, thus giving only one brood in the year. 
Unfortunately I have no notes of the markings of the larve of 
either species, but, as far as I remember, there is no great 
difference between them in this respect; but it may be worthy 
of mention that whereas 7’. bwwndularia fed readily on birch, 
T. crepuscularia would eat it only when reduced to the last 
extremity, and then very sparingly, and showed a decided 
preference to wild plum over all other foods offered to them. 
Whether our two species under discussion are of common origin 
—surrounding circumstances having induced an intermediate 
brood which became perpetuated, or, as would appear more 
probable from the comparatively restricted range of distribution 
of 7’. biundularia, local influences prevented, and in course of 
time altogether extinguished, the summer emergence—is a 
question upon which it is unnecessary to enter here; and, 
be that as it may, I see no reason at the present time for 
considering Tephrosia crepuscularia and T’. biwndularia other 
than distinct species. —R. Apxin; Lewisham, S.E., May, 1886. 
TEPHROSIA CREPUSCULARIA AND ‘I’. BIUNDULARIA. — I quite 
agree with the Rey. G. A. Smallwood (Entom. 39), that until more 
light is thrown upon the subject 7’. crepuscularia and 7’. biundu- 
laria cannot be definitely distinguished. I was told some years 
ago, by an entomologist of some authority, that we did not take 
T’. crepuscularia in this locality, as it was a southern insect. Yet 
the concluding remarks of Mr. South (Kntom. 101), point to the 
fact that both species usually occur in the same localities. My. 
Tutt gives March aud April as southern dates for the appearance
