Mr. S. Stevens also exhibited a number of oak-spangles, the work of Cynips 
longipennis, which had recently been found in profusion by Mr. Hewitson at Oat- 
lands. 
Mr. S. Stevens announced the death of Mr. P. Bouchard at Santa Martha, whither 
he had gone to collect; and read a letter from Mr. Plant, dated Tamatavi, September 
2, 1865, in which the writer recounted some of his entomological experiences in Mada- 
gascar. 
The President called attention to the account published in that morning’s news- 
papers of the wreck of the “* Duncan Dunbar” on the reef Las Roceas, in long. 83°45! 
W., and lat. 3° 52’ S., on the 7th of October. The vessel struck the reef at high water, 
and became fixed upon the rock upon a small spot of which the passengers were landed. 
“On landing it was found that the little islet 6r bank of sand was covered with pig- 
weed, but there were no signs of water. . . . The island seemed quite covered 
with birds, which from their very wildness took no more notice of men or women than 
to move a few feet out of our way. The ground swarmed with a large species of earwig, 
and was in many places honeycombed by the holes of land-crabs.” He was curious 
to know what pig-weed was, and whether the so-called earwigs were really Forficule : 
the reef was probabiy a recently-raised coral reef, and it would be very interesting to 
learn what were the first insect-forms which effected a settlement upon the newly- 
formed island. 
The President read the following :-— 
Note on Calamobius and Hippopsis.—When M. James Thomson, in his ‘ Essai, &c.,’ 
referred Stenidea to Blabinotus, he was immediately followed by Schaum, Grenier 
and de Marseul in their respective Catalogues. I directly called attention to that 
mistake, and it is now admitted. In his more recently published ‘ Systema Ceramby- 
cidarum,’ M. Thomson refers Calamobius (Guérin) to Hippopsis (Serville), and in this 
I am surprised to see that he has been followed by M. Léon Fairmaire in the ‘ Genera 
des Coléoptéres.’ The two genera agree, it is true, in their slender habit, but they 
are perfectly distinct, and do not belong even to the same sub-family. Calamobius 
has 12-jointed antennz, with antennary tubers non-approximate and nearly obsolete, 
small facets to the eyes, and small claw-joints; Hippopsis has 11-jointed antenne, 
with well-developed tubers contiguous at the base and neatly erect, coarsely granulated 
eyes, and large claw-joints, as long as the three other joints of the tarsus taken together, 
whilst in Calamobius they scarcely form more than one-third of its length—a structure 
indicating different habits of life.” 
Mr. Hewitson communicated the following note :— . 
“Tt is interesting and worthy of notice that, in the second part of the Annals of 
the Entomological Society of France for this year, there is a tigure of a variety of Chry- 
sophanus virgauree from Zerniatt, upwards of 5000 feet high in the Swiss Alps, which 
has a row of pale blue spots on the posterior wing, exactly resembling specimens of 
Chrysophanus Phlozas which we have lately received from the northern highlands of 
India. This variety of C. Phloeas is figured in Cramer, pl. 186, under the name of 
Timeus.” 
The Secretary announced the receipt of a communication from Mr. G. J. Bowles, 
Sec. Ent. Soc. of Canada, Quebec Branch, dated September 1, 1865, “ On the occur-
