18 THE entomologist's RECORD, 



evidently come to grief in crossing. They have often been observed 

 migrating at a great distance from the land. Darwin states that a 

 large species of Anidimn flew on board the Beagle, when the ship was 

 to windward of the Cape de Verd Islands, and when the nearest 

 point of land, not directly opposed to the trade wind, was Cape 

 JUanco, on the coast of Africa, 870 miles distant. Scudder records 

 that on November 2nd, 1H65, a ship, making the voyage from 

 Bordeaux to Boston, when 1,200 miles from the nearest land was 

 invaded by a swarm of ScMstoccira perenrina, the air and the sails of 

 the ship being filled with them for two days. 



Sloane in his " History of Jamaica " states that, in 1619, locusts 

 devastated the Island of Teneriffe, that they were seen to come from 

 Africa when the wind was blowing thence, that they flew as far as 

 they could, then alighted on the water, one on the other, till they 

 made a heap as big as the greatest ship, and that the next day, being 

 refreshed by the sun, they took flight again and landed in clouds at 

 Tenerift'e. 



De Saussure considers that the great oceans are, as a rule, impass- 

 able barriers and that not a species of the (Kdipodidcs has passed from 

 the Old World to the New. Sharp, on the other hand, thinks it 

 possible that sSvhistorcrca ftcrci/rina, one of the Acruliodea, may have 

 been, originally, an inhabitant of America, and that it passed from 

 thence to the Old World. 



As we have already stated, the true migratory locusts are not at 

 all numerous. The most abundant and widely distributed is Facluj- 

 t>/liis rincrosrcHs which has invaded a large part of the Old World 

 from the western shores of Europe to China. It is the commonest of 

 the migratory locusts in Europe. A nearly allied species, P. miiira- 

 toriKs, appears to limit its migrations to Turkestan and eastern 

 Europe, whilst 1\ manuoratHH has almost as wide a range in the Old 

 World as P. cinerasrcns. It is, however, more distinctly confined to 

 tropical districts. All these species belong to the tribe (Kdipodidoi.

Three New Species of Platycleis from Herzegovina. 



By MALCOLM BURll, F.E.S., F.Z.S. 

 In my trip in south-eastern Europe during last summer, I took 

 three new species of Orthoptera in the great Prenj group of mountains 

 in northern Herzegovina. It is a curious fact that they are all of the 

 same genus, namely, VlaUjiicia, Fieb., and, further, two of them are very 

 closely allied, and fall into the same division of the genus, which 

 includes also P. saus.^iorana, Frey, and I', fiixra, Br. The first of these 

 occurs in the mountains of Central Europe, while the latter has been, 

 so far, only recorded from Taygetes. The third of my species is very 

 distinct in possessing a well marked central carinula on the disc of the 

 pronotum. No other described species of the genus has this character, 

 the carinula usually being only visible on the posterior part. Brunner 

 informs me, in lift., that he possesses a female of an undescribed 

 species from the Caucasus, showing the same peculiarity. It falls 

 into the group containing 1\ n'ttata, Charp., and 1\ tessellata, Charp.,
