rales and urlicolw ; the former having the wings 
marked with obscure spots, the latter for the most 
part with transparent spots. 
In his earlier works, Mantissa and Species , Fa- 
bricius made no important change on the Linnasaii 
method ; but the many additional species which 
had come to his knowledge when he drew up his 
Systema glossatarum , led him to establish many new 
genera, and remodel the arrangement of the old 
ones. This method consists of forty-one genera, 
most of which have been adopted by subsequent 
authors ; but it is less complete than it might other- 
wise have been rendered, owing to the death of the 
author before it was finished. Latreille did not 
deviate materially from the Fabrician method, adopt- 
ing nearly all the genera ; but he did not derive the 
distinctive characters exclusively from the antennas 
and palpi, as the Danish entomologist had done, 
but had recourse to other parts of structure, and 
likewise judiciously took into account the peculiari- 
ties of the caterpillar and chrysalis. Several ar- 
rangements were proposed subsequent to or contem- 
poraneous with that of Latreille, such as those of 
Lamarck, Dumeril, Dalman, &c. but most of them 
are of little importance. The last mentioned indi- 
vidual, however, appears to have been the first to 
apply to actual practice, in his description of the 
lepidoptera of Sweden, characters derived from the 
neuration of the wings, the value of which were 
first pointed out by Mr. Jones, in a paper in the 
Linnsean Transactions, published in 1794. Godart.
