130. Gryllus migratorfus: thorax fubcarinate, of a 
Tingle fegment; mandibles blue. Inhabits Tartary, and 
migrates in incredible fwarms into various parts of Eu¬ 
rope. The mifchief thefe voracious creatures do, when 
they appear in vait legions, far exceeds the calamities 
occalioned by any other tribe of animals. By fuddenly 
deftroying all vegetation, they change the 1110ft fertile 
provinces into barren deferts, leaving behind them defo- 
Jation, and famine, and difeafes. They have occafion- 
ally appeared in fra,all flights in England, but have pe¬ 
ri filed in a Ihort time. This was probably the fpecies 1 
which conftituted one,of the plagues of Egypt. Numbers , 
til. x. Niebuhr fpeaks of them as follows : “ In Egypt 
I faw once a cloud of locufts, which was brought by a 
fouth wind from the deferts of Lybia ; the locufts fell 
Vol. IX.-No. 565. 
[i L U S. 
in prodigious quantities on the roofs of the houfes, and 
in the ftreets of Kahira. I faw no more of them,^ till 
at Jidda, in November 1762, a large cloud of locufts 
was driven over the city by a weft wind. The cloud 
came from the other fide of the Arabic Gulf; and, there¬ 
fore, many of the infedls mult have been drowned in their 
pafiage. In the month of July following, we found a 
final! quantity near mount Sumara, which feemed to 
have fp.ent the feafon in Arabia. Thefe fwa-fms often 
crofs the Red Sea a fecond time, and return to Egypt, 
the upper part of which, adjoining to the deferts of Ly¬ 
bia, feems to be the cradle of thefe animals. I faw 
clouds of them in Perfia,. and Syria ; where, in the 
quarter of MoJfu- 1 , I found nefts of thefe infedts, which 
a careful police might in a great degree deftroy. Small 
locufts, of the fize of a fly, grow with amazing rapidity , 
and attain their natural fize within a few days. There 
are undoubtedly various fpecies of this infeft, which 
have not as yet been fufficiently difcriminated. Mr, 
Forfkal calls the locuft which infefts Arabia gryllus gre- 
garius, and thinks it to be different from that which is 
:Called by Linnasus gryllus migratorius, and which is a. 
.native of the deferts of Tartary, from which it paffes 
through the neighbouring countries, into Poland and 
Germany. The gregarius merits this denomination ; for 
the locufts of this fpecies appear to a£t in qoncert, and 
to live and travel.in fociety. Thofe which remain after 
the departure of the great body are only irregular ftrag- 
glers. The Arabians diftinguifh feveral feparate fpecies 
of this infedt, to which they give particular names. But 
thefe names are not exprefiive of any qualities in the 
nature of the animal; as they refpedt only the delicacy 
afcribed to its flefli. They give the name muken to the 
red locuft, which is efteemed fatter and more fucculent 
than any of the others; they likewife eat the light lo¬ 
cuft ; but abftain from another, called dubbe, becaufe it 
has a tendency to produce diarrhoea. All Arabians, 
whether living in their native country, or in Perfia, Sy¬ 
ria, and Africa, are accuftomed*’to eat locufts. The 
Turks, on the contrary, have an averfion for this fort 
of food. If the Europeans exprefs any thing of the fame 
averfion, the Arabians then remind 11s of our foiidnels 
for oyfters, crabs, and lobfters. A German, who had 
long refided in Barbary, affured 11s, that the flefh ot this 
infedt tailed like the fmall fardine of the Baltic Sea, 
which is dried in fome towns of Holftein. We faw locufts 
caught, and put into bags, or on firings, to be dried, in 
feveral parts of Arabia. In Barbary, they are boiled, 
and then dried upon the roofs of the houfes. The Be¬ 
douins of Egypt roaft them alive, and devour them with 
the utmoft voracity. We faw no inftance of unwhole- 
fomenefs in this article of food ; Mr. Forlkal was indeed 
told, that it had a tendency to thicken the blood, and 
to bring on melancholy habits. The Jews in Arabia 
are convinced, that the fowls, of which the Ifraelites 
ate fo largely in the defert, were only clouds of locufts; 
and laugh at our tranflators, who have fuppcded that 
that they found quails where quails never were. The 
fwarrps of thefe infedls darken the air, and appear at a 
diftance like clouds of fmoke. The noife they make in 
flying is frightful and ftunning, like that of a water-fall. 
When fueh a fwarm alights upon a field, it is wafted, - 
and defpoiled of its^verdure. The pulfe and date-trees 
buffer greatly from the locufts; but corn, either ripe or 
nearly fo, is too hard for their ufe, and they are obliged 
to fpare it.” This definitive infect is reprefented at
