consist of an intermixture of Central Asiatic and Himalayan species, as 
might have been expected from the position of the country. Two species 
(a Bat and a Vole), apparently new to science, were named respectively

in the chair. 
Mr. F. P. Pascoe exhibited a large series of Arescus histrio, collected in 
Peru by Mr. Buckley, and interesting as showing the extreme variability of 
the markings on the elytra of this species. 
The Rey. H. 8. Gorham remarked that he had also observed this great 
variability, and that he possessed one specimen in which the markings were 
unsymmetrical on the two elytra. He stated that although the markings 
were so variable, the colour of the antenne appeared to be always constant. 
Mr. C. O. Waterhouse had also seen a specimen marked unsym- 
metrically, and had likewise observed the constancy in the colour of the 
antenne. 
Mr. T. R. Billups exhibited four species of Pezomachus new to Britain, 
viz., P. Miilleri, P. juvenilis, P. intermedius, and P. incertus. He also 
exhibited twenty species of Coleoptera found in a small parcel of corn-refuse 
from Mr. Fitch’s granaries at Maldon, viz., Calandra granaria, Linn., and 
C. oryz@, Linn.; Trogosita mauritanica, Linn.; Lemophlaus ferrugineus, 
Steph., and L. pusillus, Schén. (rare); Silvanus surinamensis, Linn. ; 
Monotoma quadrifoveolata, Aube (rare); Byphaa fumata, Linn.; Ptinus 
Sur, Linn.; Niptus hololeucus, Fald.; Gibbiwm scotias, Fab.; Rhizopertha 
pusilla, Fab. ; Alphitophagus 4-pustulatus, Steph. ; Tribolium ferrugineum, 
Fab., and 7’. confusum, Duval; Latheticus oryz@, C. O. Waterhouse (a new 
species); Hypophleus depressus, Fab. ; Alphitobius piceus, Oliv.; Tenebrio 
molitor, Linn., and 7’. obscurus, Fab. 
The President exhibited two specimens in alcohol of a species of 
Phasmide forwarded by a correspondent in St. Vincent. 
Mr. W. B. Cansdale exhibited a specimen of Tischeria gannacella, a 
species of Tineina, recently added to the British list, bred from Prunus 
spinosa in May, 1878; he also exhibited a remarkable variety of Cidaria 
russata. 
Mr. John Scott communicated a paper ‘‘ On a Collection of Hemiptera 
from Japan.” 
Mr. C. O. Waterhouse read a paper entitled “ Description of a new 
species of the anomalous genus Polyctenes,” and exhibited a diagram 
illustrating the structure of this insect."—R. Mexpoxa, Hon. Sec.
