mens of that species, the absence of any light edging to the cleft, and 

 in being devoid of any light colour upon the terminal joints of the 

 legs; — from Ft. hipunctidactylus 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 hipunctidactylus 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 difiereuces ; but this 

 may be said of other species in this very peculiar group, wherein larvae 

 without the most remote apparent relationship in form, markings, or 

 habits, produce entomological puzzles. 



This description of Ft. Hodgkinsonii was read in a paper upon 

 the British Fterophoridce before the Northern Entomological Society, but 

 was kept out of their Transactions to make room for other matter.

Notes on Sterrha sacraria. — I am sorry I can report no better success tlian Mr. 

 Llewelyn with this species. The larvre 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 pupte 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 find 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 gi'eater 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.
