342 Dr. ee Buwrmeister’s Description, §c. 
The genus belongs, according to the arrangement of 
M. Putzeys, repeated by Lacordaire (Genr. d. Coleopt., 
i., 190), to the section with arcuate and acuminate man- 
dibles, and takes its place alongside of the two genera 
Lachenus and Cryptomma, uniting in 
some respects the peculiar configuration 
of both. But from these two genera 
Obadius is especially distinguished by 
the form of the mentum with its three 
equal acute apical teeth, and also from 
Cryptomma by the prominent eyes. The 
fine transverse striation of the pronotum, 
which, as far as I know, is unique in the 
whole family of Scaritide, seems to be a 
very singular character of this insect. 
The accompanying figure shows this 
fine striation and also the peculiar con- 
figuration of the head; indicating the lateral production 
near the clypeus, and the mandibles crossing, one over the 
other, when closed. All the other organs are less remark- 
able, resembling those of Clivina and other genera of the 
family, and therefore I have not thought it necessary to 
figure them.
