fitles) we are obliged to that very Inqulfulve and In-- 
genious Gentleman, Mr. J, Auhrey^ S. R. S. who received 
them fome Years rint:e from Tangier. As yet I have but 
one fent me out of Wales, which you may Command if 
you pleafe, for 1 expedi (hortly niore of them. 
This Pilgrim-Locuft I call, Locufla erratica^ alis ich- 
ihyocoll^ adinjlar pellucUis, retkulatis maculis conjperfis. 
It is in length ( from the Head to the tips of the Wmgs) 
three Inches and |, of a reddifh colour all over, except 
the Wings. As to the Head and Caputium^ it refembles 
the Fourth Figure of Moufetus. The Eyes are promi- 
nent and very large, fomewhatof the form and bignefs 
of Gromwel-feeds, of a reddifti colour,elegantly ftreaked. 
The Antennce broken fo that I can fay nothing of 
the length of them : They are about the bignefs of a 
Hog's bridle, and curioufly genknlated. As to the 
tegs, the firft pair are not quite an Inch long ; the fe- 
Dond, fomewhat above that length ; but the third two 
Inches and \. Thefe hind-legs are very beautiful ; for 
the Thighs are hexangular, and elegantly fcaled on the 
cutfide, witha black Lift extended lengthways through, 
the raidft of them. The lhaaks are of a lively red co-»- 
lour, adorned on the hind^part with two orders of fmall 
fliarp prickles, placed not oppofite to each others, but 
alternately. The Wings are about three Inches longj 
reftrabling very much thofe of the larger Lihella^ or 
Dragon-flies, but all over garniflied ( the outer Wings- 
at leaft ) with reticulated black fpots. 
I fee not much reafon to doubt but that thefe are the 
very specks q{ Locufls, fo Famous in Hiftory for 
their wandring over, and depopulating whole Regions.
