MONOGRAPH OF THE 
Tlie examination of the structure of tlio mouth of Platyrhopalus, 
which I have detailed in my former article, has produced a result at 
variance with Dr, Burmeister’s views, and from an investigation of 
the characters afforded by the wing veins of the Coleoptera, I 
believe it will be found that this ingenious relationship is equally 
unfounded ; for it is to be observed that not only is the form of the 
wing of the Paussidse quite unlike that of the Carabidae and 
Dyticidse, but that the arrangement of the wing-veins is much less 
complicated, and the part of the wing where the fold takes place 
is much further removed from the extremity of the organ in the 
Paussidse; it is true that like those families it possesses a small 
cell at the recurved extremity of the radial vein, but this can 
scarcely be entitled to the weight which Dr. Burmeister would 
give to it, since it is wanting in all the Cicindelidso which I have 
examined,* and yet the relationship of these with the Carabidm is 
infinitely more decided than that of Carabus and Paussus. It is 
to be observed, how^ever, that the genera Rhj'sodes, Catogenus, 
Passandra, &c., which I have hitherto regarded as the nearest 
allies of the present family, differ entirely in the arrangement of 
their wing-veins, the extremities being entirely destitute of longi¬ 
tudinal veins. The texture and general appearance of the body, 
the dilated antennm having (as in the Cerapteri, &c.) no appear¬ 
ance of clavation at their extremities, the form and insertion of 
the feet and the anomalous sti'ucture of the mouth are, however, 
characters which I am still disposed to regard as of equal importance 
with those insisted upon by Burmeister. The Paussidm, in fact, 
are an isolated and extremely anomalous group, and which every 
fresh discovery renders more perplexing to the entomologist. 
The species of the genus Paussus may, for convenience, bo 
arranged in the following divisions and subdivisions: 
Skctjon a. Prothorax quasi bipartilua, 
a. Antcnuarum clava postico liaud cxcavata, 
b. Antennarum clava postice excavata. 
* Species Indict. 
* * Species Africans. 
,, B. Prolhorax subcoatinuus. 
a. Species Africanas. 
b. Species Indicjs. 
Section A. Protborax quasi bipartitus. 
SuB-BECTioN a. Antcanaruni clava postico baud excavata. 
* This ch.'u-acter, hitherto unuoticed, will at once distinguish the family Cicindelida* from 
the Uiiiiisean Caiabi, since all the sub-'arailies of the latter group possess this little cell.
