34 Dr. Lichtenstein's D/fertaticn on two Nalural Genera' 



This may be fufficient for the nomenclature of the two genera 

 which I have taken tlic Uberty to name in German B/ai/fcbrecke, or 

 Laubfchiecke, and Fangfchrecke. It is unnecefTary 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 Entomologla- 

 Syjlematka we find in all 51 Mantes; I here defcribe 25 Phafmata 

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

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

 fectly fure: it may be, and is, indeed, the faift, that I have added 

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

 and corred, but they are frequently infufUcient 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 whether this or that fpecies delineated by Stoll, where I do not cite 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 Entomologla Syjlematka^ 

 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- 

 ing in StolK 



Every one acquainted with the fubjedl will obfervs, that the firft 

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

 that the difference of the habit ftruck alio the attention of this 

 fharp-fighted entomologlft. The Phafma cltrlfoltum alone has gone 

 aftray among the Manter, under the name of M.Jicclfolla, 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 Phafma 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 that the female is not already reckoned among the fpecies. They 



are
