$10 MODERN CLASSIFICATION OF INSECTS. 
Tke number of these insects is very great, nearly equalling any of 
the other orders, with the exception of the Coleoptera; thus, Dr 
Burmeister supposes them to amount to not fewer than 12,000, or 
nearly one sixth of the whole of the insect tribes ; and Stephens de- 
scribes nearly 2000 species, or nearly one fifth of our indigenous 
insects. The number of exotic species is probably even greater, con- 
sidering the greater share of investigation which has been given to 
the more minute species of the order in this country* than on the Con- 
tinent, whence we may infer that much still remains to be done. Ama- 
teurs enough are to be found, both at home and abroad, who content 
themselves with collecting and describing the more showy and larger

* A recent continental reviewer has expressed his astonishment that so great a 
proportion of Wood’s Index Entomologicus should be occupied with the minute 
Lepidoptera. ** Vorzuglich die Microlepidopteren sind mit Vorliebe und Geschick- 
lichkeit behandelt, und sie allein fullen uber die Halfte des Werke, da sie von den 
Pyraliden ab mit dem eilften Hefte beginnen.” Germar’s Zeitschr fiir die Entom.
