 burneth." {Joel, chap. ii. verse 3.) 



The follovifing synonymes of the three families may be serviceably 

 introduced, so as to show, at a glance, the views which have been 

 entertained respecting their nomenclature.

The Linnaan name Bulla has been entirely dropped, having been 

 previously employed for a genus of shells; but that of Acrida, and its 

 diminutive Acrydium, have been as much confused in their application 

 as the other Linnaean names ; Fabricius, Leach, Stephens, &c., giving 

 the latter to some of the Linnaean Bullae ; Latreille to the true locusts ; 

 and Kirby to the grasshoppers with long antennae. I have shown 

 above that it ought either to be dropped, or employed instead of 

 the modern generic name Truxalis. The Linnaean Bullte will still, 

 however, require a different name ; and, in order to avoid all further 

 confusion, it will be evidently most advisable to employ Latreille's 

 name Tetrix for some of them, instead of Acrydium, and that of 

 Pneumora for others. 



The first of these three families, Achetid^ *, comprises the 

 insects ordinarily called crickets f {Jig. 54. 1. Acheta domestica ? .,

■f- The English name cricket, and the French name cri-cri, given to these in- 

 sects, is an imitation of the sound which they produce. It is surprising, tlicre- 

 fore. that in French works which furnish us with the latter name, we sliould 

 find the French synonymous name criquet given to a distinct family, namely, that 

 of the migratory locusts.
