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

 portionately the reverfe in all thefe refpe6ts, that is, the whole form 

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

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

 nation. 



From this digrefllon on the fexaal differences in both genera, I 

 return to the account which I propofed to give. 



In Gmelin's thirteenth edition oi t\\c Syjlema Nature the Phafmaia 

 fland as in Linne, intermixed with the Mantes. But we find fome 

 enumerated amongft them that Fabricius has not. The M. cylindrical 

 n. 54. is doubtlefs the male-of jVf. necydakides. I have united both 

 under Ph. navium. M. phthiftca is probably the male of my Ph. edulc. 

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

 M, gigantea '\.s our Ph. angulatum, as I rather choofe to call it after 

 Fabricius; it js diis 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 afcertain to which family they belong, i. M. fuper- 

 Jlitiofa of that author, n. 27. appears to belong to the Mantes with a 

 flattened body^ rounded feet, and round eyes, and in my feries to 

 come in between M.Jlrumaria and precaria. 1. M.fcnejlrata, n. 38. 

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

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

 lobipes and mendica. 4. M..ru/}iai, n. 43, mufl:, according to analogy, 

 .be alfo arthritical; and in that cafe it follows M. pedlinicomis. 

 5. M^faujla, Fabr. n. 47. is fcarcely a fpecies eflfentinlly different from 

 the M. Gculata. 6. M. perfpicua muft be placed diredly 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 relationlliip with any certainty, i. M. nmculata, n. 45.
