54 -C^^' Lighten stein's Differ tat ion on two Natural Gemra- 



This may be fufficient for the nomenclature of the two gcnersi 

 which I have taken the liberty to name in German Blattfchrecke^ or 

 Laubfcl:}recJze, and Fang/chrecke, It is unneceffary to repeat here all 

 that I have faid in Latin; I will only make a few general remarks,, 

 efpecially on the fpecies omitted" by Fabricius. In the Entomologia- 

 Syjlematica we find in all 51 Mantes \ I here defcribe 25 Pioafinata-: 

 and 43 Mantes^ together 68 fpecies; hence it might be concluded,, 

 that 1 had 17 new fpecies; but this mode of reckoning is not per- 

 fectly furc : it may be, and is, indeed, the fa6t, that 1 hav^e added.' 

 more than 17 fpecies. The defcriptions of Fabricius are very good 

 and corred, but they are frequently infufficient to determine to whicH 

 family a Mantis belongs, and, therefore, I cannot always be certain^ 

 whether this or that fpecies delineated by Stoll, where I do not cite 

 Fabricius, may not yet be found in the Entomologia Sj^ematica- 

 But this will be very rarely the cafe, and nearly all the fpecies of 

 Fabricius, which I pafs over in the monograph, are. certainly want— 

 inc; in Stoll. 



Every one acquainted with the fubje6l will obferve,, that the firft 

 15 Mantes of Fabricius are one and all Phafmata, A certain proof 

 that the difference of the habit (Iruck alfo the attention of this 

 fharp-fighted entomologift. The Phafma citrifolium alone has gone 

 aftray among the Mantes, under the name of M.ftccifolia, n. 24. 

 This has been occafioned partly by its belonging to a peculiar fa- 

 mily, which has rather more refemblance to the Mantes than the 

 other Phafmata, and partly from this circumftance, that Fabricius was 

 acquainted only with the female, and not with the male, which bears 

 much ftronger marks of a Phaftha than the female. Three fpecies 

 of Phafma occur in Fabricius which Stoll has not, and which I 

 have hefitated to number in the order of fpecies. Not that I doubt 

 their exiftence, but becaufe they are males, and I cannot be cer- 

 tain tJiat the female is not already reckoned among the fpecies. They
