mens of that species, the absence of any light edging to the cleft, and 
in being devoid of any light colonr upon the terminal joints of the 
legs ; — from Ft. hipunctidactyhis in its smaller size, more yellowish 
ashy-colour and lighter coloured legs, and from the spurs being of the 
same colour as the legs, whereas in hi])unctidactylus the spurs are lighter 
than the legs. 
While in company with my friend J. B. Hodgkinson, this species 
was first discovered in a small pasture-field at Witherslack, on the road 
from the Inn to the Moss, early in June, about the year 1860. Sub- 
sequently Mr. Hodgkinson met with three specimens on the juniper 
field, one of which he kindly gave to me to make up my pair, one he 
presented to Mr. Doubleday, and one went to Mr. Burney. Since 
then he has taken one or two more specimens, and these are all I know 
of. That the species is nearly allied to Ft. Lowei is self-evident ; 
indeed, none but a practised eye would detect the differences ; but this 
may be said of other species in this very peculiar group, wherein larv33 
without the most remote apparent relationship in form, markings, or 
habits, produce entomological puzzles. 
This description of Ft. SodgJcinsonii was read in a paper upon 
the British Fterophor ides before the Northern Entomological Society, but 
was kept out of their Transactions to make room for other matter.

Notes on Sterrlia sacraria. — I am sorry I can report no better success than Mr. 
Llewelyn with this species. The lavvaa he so generously sent me fed up well, and 
all began to spin ; two died without becoming pupae, while the rest completed the 
change ; and, had they behaved as satisfactorily as the famous half-dozen in 1865, 
they would have appeared in the perfect state during the latter half of October ; 
but up to this date not an imago has emerged. I have examined two of my 
cocoons, and found dead pupso in them ; most likely there is nothing better in the 
rest, but with a lingering, desperate hope T am keeping them on in a room with a 
fire, unwilling to destroy the least chance there may yet exist of seeing a moth. 
Mr. Llewelyn's brood were hatched two or three days earlier in August than 
the '65 brood ; but on reference to a daily register of the temperature here in 
Exeter, I iind they did not enjoy such a favourable time for their development. 
Throughout September and October, 1865, the thermometer stood several degrees 
higher than in the same months of this year, with the exception of one frosty night 
in October ; and, as sacraria is believed to have its head-quarters in climates much 
warmer than our own, we may suppose that the greater success of the former brood 
is thus accounted for. At the same, if we allow that cold is so fatal to sacraria, we 
are met by the question— How then can it establish itself at all in this country ? 
For we can scarcely suppose that the specimens taken year by year are fresh 
immigrants, or that their offspring are produced during the warmer months.
