428 THE ZOOLOGIST. 
Gr., captured at Weybridge on July 25; and Lissonota anomala, Holmgr., 
captured at West Wickham Wood on May 7th. The handsome Pezomachus 
aylochophilus had also been taken at Blundall, near Norwich, by Mr. 
Bridgman. 
Mr. C. O. Waterhouse exhibited the larva of an Gistrus which had been 
taken from the side of a specimen of our common domestic mouse (Mus 
musculus), received from Peru, which was also exhibited. The Mstrus 
larva measured one inch by five lines broad at its widest part, and occupied 
almost the whole of one side of the mouse; when extracted its head was 
found towards the posterior legs of the mouse. Specimens of Holochilus 
apicalis, Peters, Hesperomys caliginosus, ‘Tomes, and Hesperomys olivaceus, 
G. R. Waterh., all received in the same collection from Peru, were similarly 
attacked and one specimen of Mus musculus coutained two larvee of the 
Estrus. 
Mr. G. H. Verrall remarked that in Brauer’s ‘Monographie der 
Qistriden’ there was no mention of any species living on the Murida (mice), 
but that in a later paper (Verh. z.-b. Ges. Wien. xiv. 891, pl. xxi. B) Brauer 
had referred to and figured a species of G?stromyia? whose larva had been 
found on a field mouse (Arvicola arvalis, Pallas), at Langenberg (Wurtem- 
berg) by Prof. Hering, occupying quite a different position, however, to the 
specimen now exhibited. 
Mr. H. ‘I’. Stainton exhibited two specimens of Char@as graminis, bred 
from the grass-feeding larvee from Clitheroe by Mr. F. 8. Mitchell, thus 
surely identifying the lepidopterous larvee which occurred in such great 
numbers (cf. p. 349 ante). Mr. Fitch said C. graminis had also occurred as 
a “plague” in the Thuringian Forest this year, Herr Gutheil recording 
that from twenty-five to thirty specimens of the larvee or pupe were found 
to the square foot, making about seventy millions to the ninety acres 
affected (Ent. Nach. vii. 253). 
Sir Sidney S. Saunders exhibited specimens of Sarcophaga lineata, Fall., 
another dipterous parasite on locusts in the Troad, whose larve, feeding 
internally ou the adipose tissues of their victims, had powerfully contributed 
to clear a considerable tract of country from those which had escaped previous 
destruction in the egg by the Callostoma. Also specimens of Chaleis 
minuta, Fabr., which were bred from the Sarcophaga pups. The locust 
proved to be Cidipoda cruciata, Charp, several specimens of which were 
exhibited. 
The President read a letter from the Colonial Office acknowledging the 
receipt of the report on the insect attacking locust-eggs in the Troad, and 
requesting that “ Lord Kimberley’s thanks be conveyed to the Society for 
this valuable report.” 
Mr. C. O. Waterhouse read the “ Descriptions of some new Coleoptera 
from Sumatra.” Anomala (Spilota?) Curtisii (Rutelidw), Macronota anceps
