 News, Vol. XXXIX, pp. 212-215 (1928). 

 The authors discuss the inconsistency of the use of this word to 

 indicate the hardening of the integument of insects when the term 

 was introduced by Odier to indicate the soft, colorless cuticula 

 after the hardening substances and pigment had been removed by 

 boiling in caustic potash solution. 

 Snodgrass, R. E. "Some further errors of body-wall nomenclature in entomol- 

 ogy." Entomological News, Vol. XL, pp. 150-154 (1929). 

 He emphasizes the objections of Ferris and Chamberlin for the use 

 of chitinize, etc., for hardening the cuticula, and makes some 

 suggestions for improvements.
