ENTOMOLOGICAL SYSTEMS. — FABRICIUS. 189 
wingless insects ; but, like him, he had a most imperfect 
conception of the latter group. His departure from the 
orders established by Linneus will, by many, be ex- 
tolled as the commencement of all the good that has been 
since matured ; while, by others, it will be designated 
as the first commencement of those erroneous theories 
which, in modern times, have led us astray from nature. 
(241.) Fabricius was the great systematist of his 
day ; but his classification, once so prevalent, has long 
been abandoned. He published two systems; one in 
1775, and the other in 1798. The primary groups of 
the latter, as drawn up by Messrs. Kirby and Spence, 
are here subjoined ; chiefly for the purpose of showing 
the passion for new names, which now began to arise 
among the continental naturalists, and to illustrate the 
different conceptions of entomological groups entertained 
by our author from those of Aristotle, Linneus, and 
De Geer : —
