^S Dr. Lichtenstein's Di/feriation on two Natural Genera 



and longer; the thumb rounder and longer. The females are pro- 

 portionately the reverfe in all thefe refpects, that is, the whole form 

 i§ heavier, broader, flatter, and firmer. The proper organs of gene- 

 ration of the Mantes do not, in dried fpecimens, admit of exami- 

 nation. 



From this digreffion on the fexual differences in both genera, I 

 return to the account which I propofed to give. 



In Gmelin's thirteenth edition of the Syjlema Nature^ the Phafmata 

 ftand as in Linne, intermixed with the Mantes* But we find fome 

 enumerated amongft them that Fabricius has not. The M, cylindrica., 

 n. 54. is doubtlefs the male of M. necydaloldes, I have united both 

 under Ph, naviimi, M, phthijica is probably the male of my Ph, edule, 

 M. labiata is alfo a Phafma^ but I can fay nothing further of it, 

 M. gigantea IS our Ph» angulatum, as I rather choofe to call it after 

 Fabricius; it is this fpecies defcribed from a female. 



I now come to the proper Mantes, I muft- here enumerate the 

 following from Fabricius, which I have been obliged to omit, not 

 being able to afcertaiii to which family they belong, i. M. fuper^ 

 Jl'itiofa of that author, n. 27. appears to belong to the Mantes with a 

 liattened body, rounded lieet, and round, eyes, and in my feries to 

 come in between M.Jlrumaria and precaria, 2. M.fcnejlrata, n. 38. 

 appears to claim a place in the fame family and party. 3. M, bldens^ 

 n, 39. belongs to my arthritic divifion with round eyes, between 

 labipes and mendlca, 4. M. rujlica^ n, 43. muft, according to analogy, 

 be alfo arthritical; and in that caie it follows M. pedtinicorms, 

 ^.M.faufici, Fabr. n, 47. is fcarcely a fpecier. cfTenti-illy different from 

 the M. cculata. 6. M. perjpicua muii be placed dire6ily after my 

 neuroptera. 



The following Mantes of Gmelin I am quite at a lofs to arrange, 

 as I have no fufficient accounts to enable me to afcertain their fa- 

 mily and lelationlhip with any certainty, i. M, maculata^ n. 45-.
