Comprising survey. 



The following conspectus is based on the standard- 

 works of I. C. Schi ødte (De raetaraorphosi eleutheratorum. 

 Pars III. Naturhist. Tidskrift. 3 R., vol 4, 1867 and Pars 

 VI. 3 R., vol 8, 1872). I am greatly indebted to the ex- 

 cellent descriptions by G. de Lapouge (Description des 

 larves de Carabus et de Calosoma. Bulletin de la société 

 scientifique et médicale de l'Ouest, Pars I., 1905; Pars IL, 

 1906; Pars 111., 1907; Pars IV., 1908); further to the im- 

 portant and admirably careful publication by George Dim- 

 mock and Frederik Knab (Springfield museum of na- 

 tural history. Bulletin No. 1. Early stages of Carabidæ, 

 with four plates; Springfield, Mass. 1904, publ. by the 

 Museum).
