made some approximation to it in size), and he should have been inclined to resort to 
the theory that it was an immature larval form, but for the observations of the Presi- 
dent, which seemed to be conclusive on that head. 
The Secretary exhibited, on bchalf of Mr. W. Rogers, a singularly pale variety of 
the female of Hipparchia Janira, captured at Tooting on the 6th of September; anda 
specimen of Rumia crategata, bred from a pupa found in an old fence at Tooting 
during the present year, in which the left fore wing and the right hind wing (with the 
exception ofa slight tinge at their outer margins) were pure white, whilst the body 
and the other two wings were of the ordinary yellow, and of not less than the usual 
brightness and depth of colour. The specimen could be regarded only as a mon- 
strosity, or dusus nature ; it was as if Nature had fallen short of colouring matter, and 
had determined that such matter as she had should be employed as far as it would go 
in the perfect colouring of certain parts, and should not be equably diffused over the 
whole surface so as to produce an insect faint and pale throughout; the transverse or 
cruciform fashion, however, in which the colouring of the parts had been completed 
was curious. 
- The Secretary exhibited some Egyptian beans, sent “from a Greek firm,” which 
on the outside appeared perfectly sound, whilst in the inside of many there was “a 
peculiar worm,’ some of which were found alive and were forwarded “ for the use of 
the Society.” The “peculiar worm” proved to be the perfect form of a species of 
Bruchus. 
The Secretary read a letter from Mr. Henry Reeks, dated “Cow Head, New- 
foundland, 13th Sept. 1866’; though but recently landed, the writer had already 
found that the Diptera, in the shape of mosquitoes, black flies and sand flies, pre- 
dominated far beyond his requirements for obtaining specimens; Lepidoptera seemed 
scarce on that portion of the island; of Hymenoptera he had seen only one species of 
Vespa, and that not V. Germanica, which he saw in Canada. 
The Rev. Douglas Timins communicated the following “‘ Note on the appearance 
of Argynnis Lathonia”:— 
“T observe that at p. 115 of the ‘ Proceedings’ for 1865, the appearance of 
Argynnis Lathonia late in September is mentioned as ‘unusual.’ As I have been for 
many years in the habit of taking that species in fine condition regularly from about 
September 25th to October Sth, and as information respecting its other periods of 
flight may be acceptable to English entomologists, I subjoin a note on this subject. 
arly in March hybernated specimens appear. The first fresh individuals emerge from 
the pupa late in May or early in June; they remain on the wing for some time, but 
are soon wasted. The second brood appears early in August, and lasts until 
September. Then, lastly, after this brood is almost over, and represented only by a 
few very tattered specimens, a small number of fine fresh specimens appear, a sort of 
third brood, in fact, late in September or early in October. These are generally 
smaller, and nearly always darker than the preceding broods; and they occasionally 
hybernate. These remarks apply only to the North of France, where the climate is 
similar to our own. In the South fresh Lathonias may always be seen, at least in 
October, November, December, February, April and May. I have even known this 
species emerge from the pupa in January (not being forced by heat). The third 
brood is so regular in its appearance that I used always, when residing in the North
