Tephrosia Crepuscularia. — Guenee 
gives the synouymes of this species thus, 
T. Crepuscularia, De Geer , W. V., Hub. 
158, &c. 
= Strigularia, Stephens, Wood. 
= Cousonaria, Wood. 
RACES OR PERMANENT VARIETIES : 
(.4). T. Abietaria, Haw., Step/i., Wood. 
= Laricaria, H. D. Cat. 
( B ). T. Biundularia, Esp. 
■=■ Crepuscularia, Haw., Steph ., 
Wood, 517. 
He says, “ T. Crepuscularia is common 
in April and May, more rarely in July, 
and T. Biundularia common in England 
in May, among the oaks.” Which of 
these two is our typical species? The 
ligure of Wood, 517, is certainly in- 
tended for it; but then the very good 
figure of Hirbner, 158, is an equally good 
representation of it. In Doubleday’s 
Catalogue, Biundularia is given as a 
synonym of Crepuscularia, W. V., which 
is the same as Guenee’s type, though he 
has preferred De Geer’s name to that of 
the W. V. That the Crepuscularia of 
Guenee is the same as ours is rendered 
clear by his remark, “ Common in April 
and May, more rarely in July,” which is 
the habit of our insect. Mr. Burney, 
I think, has made a step in the right 
direction of the proof which alone can 
settle the question of identity or diffe- 
rence between Crepuscularia and Lari- 
caria. I think it is a pity that Guenee 
should have restored Haworth’s name of 
Abietaria for Laricaria. We have thus 
two closely allied insects having the 
same name. — C. R. Bree, Stricklands ;

Note on the Flying of Bembidia. — Did 
any of my brother “insect hunters” ob- 
serve how freely the Bembidia made use 
of their wings during the remarkably hot 
summer of 1857? I most particularly 
noticed this when in Cumberland, in 
June. Species that I never saw (ly before 
would, on being disturbed, run at once to 
the top of a stone, open their wings uud 
away. I lost many from another cause : 
not wishing to bottle any but the best I 
gave every individual a separate exami- 
nation; many escaped by slipping from 
my fingers, and, taking wing as they fell 
(after the manner of a Philonlhus), were 
soon out of danger. From this cause I 
missed a series of the rare prasinurn : I 
had, on a very hot day, hunted some 
miles of the banks of the Irthing, with 
poor success, when I came to a large 
muddy bank, where punclulalum was in 
plenty, with what I took for tibiale 
amongst them, but they were so very 
active that every one escaped before I 
could make out what species it was. I 
bottled a few promiscuously ; and when 
I came to set them out at night, I had 
the mortification to find that only three 
of prasinurn were to be found ; one of 
these, on trying to escape, flew into the 
water, and I now have him mounted, 
with the wings protruding. Having to 
return home next morning, I was unable 
to do more than hope to be more fortu- 
nate another time. — T. J. Bold, in the

PROBLEMS IN GEOMETRY. 
No. IV. 
In looking through the second volume of 
M. Guenee’s ‘ Geometric,’ I find that, in- 
dependently of the genus Eupilhccia, 
which of course I am saving till the last 
as a bonne bouche, that the larvae of the 
following six species, though they have 
been collected, have never been de- 
scribed : — 
Cabera rotundaria, 
Aleucis pictaria, 
Abraxas pautaria,
