4 SYNOPSIS OF l'HASMID.E. 



Latreille refers to the above arrangement in a note, ' Regne 

 Animal,' v. p. 178, but has altered it to the following plan: 



" I. Le prothorax beaucoup plus court que le mesotborax; le 

 corps et les pattes longs, lineaiies. 



1. Apteres. 



* Antennes tres courtes, grenues, en forme d'alene. 



Bacillus. 



** Antennes notablement plus longues que la tete et en forme de 



soie. 



Bacteria. 



2. Des elytres et des ailes du moins dans Tun des sexes. 



A. Points d'yeux lisses. 

 * Pieds egalement espaces. 



Cladoxerus. 

 ** Les quatre derniers pieds plus rapproches. 

 Cyphocrana. 



B. Yeux lisses. 



Phasma. 



II. Corps plus ou moins ovalaire ou oblong, aplati, mais point 

 lineaire. 



1. Prothorax plus court que le mesotborax ; des elytres et des 

 ailes aux deux sexes. 



Prisopus. 



2. Prothorax presque aussi long que le mesothorax ; femelles 

 privees d'ailes ; males avec des elytres tres courtes. 



Phyllium." 



M. Serville has since remodelled the arrangement mentioned as 

 given by him in the ' Encyclopedie Methodique'; which alteration 

 he publisbed in the ' Annales des Sciences Naturelles' for January 

 1831. It differs but little from the former, except in the introduc- 

 tion of a new genus, Xerosoma, and in the transposition of his 

 sections of the winged and unocellated forms. 



In a notice of my monograph of the Australian species of Phasma, 

 inserted in the ' Entomological Magazine' for October 1833, the 

 reviewer has proposed, on what appear to me very insufficient 

 grounds, to subdivide two decided families (those of which Mantis 

 and Phasma may be regarded as the types,) into four ; which, with 

 the addition of a fifth for the reception of Mantispa, are made 

 to compose the Stirps (Tribe) Phasmina of MacLeay. The 

 difference between Mantidcs and Empusidce, which is made to de- 

 pend solely on the prolongation or non-prolongation of the head in 

 the shape of a horn, (a character that can have no appreciable influ- 

 ence on the habits of the two groups, which are known to be iden- 

 tical,) is too trivial, as well as too artificial, to form the basis of a
