tera,” by Ericlison, Schaum, Kraatz,Von Kiesenwetter, 
Reitter, Weise, &c. : still iu progress.

teren,” by Reitter and others : Berlin : still in pro- 
gress. 
“ Skandinaviens Coleoptera,” by 0. G. Thomson : 
Lund, 1859 — 1808. 10 vols. 
The works of Lacordaire (continued by Chapuis) and 
Duval are also of the greatest service, especially on 
account of their plates. 
The following works are necessary to students 
studying the life history of the Coleoptera : — 
“ Do Metamorpliosi Eleutlieratorum Obscrvationes,” 
by J. C. Scliiodte, 1861 — 1883 : for accuracy of obser- 
vation and delicacy of plates this work has no equal. 
“ Larves des Coleopteres,” by E. Perris : Paris, 
1877. 
“ Catalogue des Larves des Coleopteres,” by Chapuis 
and Candeze : Liege, 1853. 
As regards classification, the most valuable work 
now iu course of progress is the “ Biologia Centrali- 
Americana, Coleoptera,” by Sharp, Bates, Gorham, 
Champion, Matthews, Jacoby, &c. ; this splendid pub- 
lication is, however, far beyond the ordinary student, 
but must be consulted by any persons who intend to 
write on the groups there referred to : the Classifica- 
tion of the Coleoptera of North America, by Leconte 
and Horn (Washington, 1883), will also be found of 
very great assistance in many points. 
The Transactions of the various Entomological 
Societies that have boon formed in different countries 
(notably the French “ Annales ”) contain a large 
number of monographs and descriptions.
