EXTRACTS FROM PROFESSOR BURMEISTER’S 
MEMOIR ON THE PAUSSIDE. 
(Mag. DE Zoot. 1841.) 
After remarking upon the insufficiency of the characters derived 
from the tarsi for the natural distribution of the Coleoptera into pri- 
mary groups, and noticing that the structure of the wings has been 
hitherto unemployed in characterizing the higher groups of beetles, 
Professor Burmeister considers that in the latter character he has 
discovered the true grounds for removing the Pausside from all 
the various families with which they have been associated, and 
bringing them into the neighbourhood of the Carabide. Consi- 
dering the great service which has been long obtained by employing 
the variation in the structure and position of the wing-veins in the 
Diptera and Hymenoptera, and which has recently been extended 
to the Lepidoptera by Boisduval, Lefebvre, and more especially 
Milne Edwards (from whom we may shortly expect a most elabo- 
rate memoir upon the subject), to the Orthoptera by De Haan, to 
the Homoptera by myself, and to a portion of the Neuroptera by 
Rambur ; it is surprising that this character should have received 
so little attention amongst the Coleoptera ; and, without assigning 
to it the primary importance attached to it by Burmeister, I 
cannot regard his employment of it (as well as of the number of 
segments of the abdomen, both in this memoir and in his Handbuch 
der Entomologie, vol. 4) otherwise than as proofs of a deep and 
philosophic spirit of inquiry.
