length of the abdomen. Only one fpecies of this genus is entirely 

 without wings. 



The legs of the Fhafmaia are all formed for running, and like to 

 each other; the fore legs are placed fo near to the head that they are 

 excavated near the bafe to make room for the head between them. 

 This is a very certain natural diftinclion, by which one may know 

 whether even an imperfe6l fpecimen is a Phafmn or a Mantis, The 

 Fhafmata of the firfl family have very long and narrow fore feet, fre- 

 quently with triangular and thorny legs. Thofe of the fecond family 

 have ihorter fore legs, with broad margins. 



The Mantes have, inftead of fore legs, arms, with nearly fciffor- 

 formed hands j the upper arms and elbows are, according to the fa- 

 milies, either narrowly or widely dentated or fringed. The four hind 

 legs are for running; moflly plain, more rarely adorned with foh- 

 ated margins on the thighs, and dill more rarely on the tibice. 



This comparifon fhows fufficiently that the Phaftna and Mantis Tivo, 

 two very diftincl genera. 



Before I begin the fyftematic defcription in the manner of Fabri- 

 eius, I muft fpeak of the families or divifions of the genera. The 

 primary divifions I have taken from Stoll. They depend in both 

 genera on the rounded or more flattened {lru6ture of the whole body, 

 with which alfo the length of the fore legs agrees. The Pbafmata 

 of the firil family, that is the rounded ones^ I divide again into 

 winglefs and winged ; the flat Pbafmata require no further fub- 

 divifion. 



The Mantes of the firll: family, that is, (ioWowmz^ the fame order 

 as. in the Pbafmata^ although Stoll takes them lafb,) the rounded 

 ones, I divide into winglefs and winged. The lafl: again according 

 to their eyes, which are either angular or round. The family of the 

 flat Mantes may be feparated into two companies ; the gouty ones, 

 with leaves on their legs, and the round«legged ones, without them^
