Chair. Proceedings of Natural History Collectors in Foreign Countries—Letter 
from W. A. R. Wallace, dated Borneo, 8th April, 1855. Mr. Wallace, in writing 
about the capabilities of St. Munjon coal works as an entomological collecting 
ground, says— u I here met with the beautiful longicornis of the genera Astathes, 
Glenea, and Clytus, the elegant Anthribidse ; the Buprestidas are very fine ; one of 
the most beautiful is, I think, the Belionota sumptuosa, about one inch long, and 
of the richest golden copper colour; it flies with the greatest rapidity, making a 
loud, bee-like hum, and settles on timber only in the hottest sunshine.” How ex¬ 
citing must be the pursuit of entomology in these tropical climes after the, in this 
respect, less favoured lands of Britain \ 
No. 155, September:—(E. H. Rodd) Occurrence of the Honey Buzzard; (H. 
Stevenson) Occurrence of the Roller ; (T. J. Bold) Occurrence of the Pectoral 
Sandpiper ; (G. Norman) Occurrence of large flocks of Crossbills, near Hull; (J. J. 
Briggs) Note on the Destruction of Swallows by the severity of the Weather ; (T. L. 
Powys) Occurrence of Buonaparte’s Gull, on the Irish Coast; Child and Snakes ; 
Gonepteryx Rhamni double-brooded? remarks on this subject by H. Doubleday, 
J. W. Douglas, and H. T. Stainton. This query is here made the subject of 
several interesting communications from some of the best entomologists in Britain. 
Mr. Doubleday says the insect is not double-brooded. Messrs. Hawker and Bree 
say that it is. Mr. Stainton wonders that no one has yet made out such an 
apparently easy problem; and Mr. Douglas, in our opinion, is the only one who 
sets about settling the question in a fair and legitimate manner. (S. Price) Occur¬

No. 78, July:—(R. Spruce) Note on the India-rubber of the Amazon. The 
mode of obtaining the caouchouc from the various species of Siphonia, is almost 
universally by tapping. Some used to cut down the trees, but found that, in this 
way, they obtained much less milk than by successive tappings of the same tree, 
the work, besides, being harder, and causing'them to shift their sphere of operations 
continually. It is dried by smoke, the milk being applied in successive coatings 
to a mould. In the year 1849, the caouchouc fetched, in the Para market, only 
£1 3s. 4d. per 32 lbs. (an arroba), but when the demand began to exceed the 
supply it reached the very high price of £4 8s. 8d. the arroba ; it now sells from 
£1 15s. to £2. (G. H. K. Thwaites) Description of some new genera and species
