hitherto confounded under the Name of Mant'n, ^ 



would have been as claflical as that for which wc are indebted to 

 him on the Rhynchota. He would thus have thrown light on all 

 the Heirtiptera of Linnc, and have done as much as a fyftematic writer 

 for this order of infedts, as Pallas has for the unguiculated quadrupeds 

 among the mammalia. No one will deny, unlefs from an abfurd 

 prejudice he defpifc every thing that is Dutch without further ex- 

 amination, that the late StoU was a very diligent and fortunate ob- 

 ferver. His penetrating eye, incredibly experienced and ready ia 

 diftinguifhing objeflsat firft fight, comprehended the whole habit fo 

 happily in one fixed point of view, that he difcriminated the natural 

 genera as if by intea-nal feeling. The coUedion of Holthuyfen, which 

 he had chiefly arranged, was divided almoft univerfally into the fame 

 genera which Fabricius has adopted in his 'Eniomologia Syflematica, 

 btoll died before this work was publiflied, and Fabricius faw that 

 coUeftion only curforily in Hamburgh, when his book was all com- 

 pleted but the appendix- This agreement, therefore, between two 

 perfons thinking quite independently of each other, fliows clearly 

 that entomology is not fo uncertain and inconftant as many be- 

 lieve ; and that both of thefe gentlemen were in fearch of truth, and 

 knew how to find it. Syflematical order, indeed, is not to be ex- 

 pefted in the writings of StoUy for, as he had no learned education, 

 he was totally unprovided with that artificial logic which is more 

 ufeful to men of letters in general than they often think proper to 

 alk)W. Although the idea of this monograph was borrowed from 

 StoU, yet one acquainted with the fubjeft will foon discover that I 

 have not copied from him, but that I have bellowed much labour of 

 my own on this diflertation. 



I fhall, in the firft place, fliow that the Spetflre of Stoll, or the 

 Phafma, is truly different from the Mantis, and muft be feparated from 

 it as a diftincl genus; in the next place, treat of both in general, gbins; 

 fyftematically through their fpecies, and afceitaiuing the fyaonyms;
