304 Grays Synopsis of the Phasmidcc. 



Gray, George Robert, M.E.SS. of London and France, and 

 Author of " Entomology of Australia:" Synopsis of the 

 Species of Insects belonging to the Family of Phasmidse. 

 8vo, 48 pages. London, Longman and Co., 1835. 



Technical, elaborate, and doubtless of very high value to 

 scientific entomology. 126 species are described or indi- 

 cated; and, out of these, several new genera are instituted. 

 " In forming my table of divisions," and in characterising the 

 genera and species, " I have used only external characters. 

 The cibarian organs of species belonging to distinct divisions 

 bear so great a similarity to each other, that it is impossible to 

 make use of them as divisional characters." 50° n. and s. of 

 the equator bounds " the geographical extension of these in- 

 sects." Of them N. America has 3 ; W. Indies 8 ; S. Europe 

 3 ; Africa 2, and, probably, many more yet to be discovered ; 

 India, China, and Malay Islands, 4 1 ; Polynesian Islands 3 ; 

 S. America 29; N. Holland 27, doubtful 10. They who 

 would preserve specimens of Phasmidae, in the colours respec- 

 tive to them when alive, should open a longitudinal slit on 

 the under surface of the abdomen, and take out the entrails ; 

 stuff the cavity with soft cotton ; and allow the insect to dry 

 in an airy situation. " A milky fluid exudes from the thorax, 

 when the pin is passed through it, which is capable of staining 

 the adjacent parts yellow and other colours."
