setting forth, however, beforehand a few remarks. 
Balzan’s subgenera are entirely omitted, as I believe 
them to be correctly referred to genus. The differences 
between Garypus, Minniza and Olpium, being very 
closely connected in the essential structural features, 
are not taken into consideration. Of his sub-family 
Chthontide I only know Chthonius, but Megathis Steck. 
and Lechytia Balz. do not appear to present differences 
of any importance, and I find grounds to believe that 
the same is the case with the genus Heterolophus Tom. 
which by Balzan is placed between Megathis and 
Chthonius. According to the description of Balzan I 
suppose that his subf Mirerocreagrine does not differ 
in any capital character from Pseudobisünc, and | 
believe his family Tridenchthontide to be a Chthonius 
with a most remarkable galea. 
I divide the order into 2 sub-orders (I make use of 
the name introduced by Balzan, though in this case | 
believe that it says a little too much) answering al- 
thogether to those of Balzan, and I use his names, 
though, indeed, they are rather long. 
I. Panctenodactyli. 
The mandibles small, the distance between their 
exterior hind corner hardly more than half as large as 
the breath of the posterior margin of the cephalothorax 
and mostly much shorter. 
Serrula on the movable finger grown fast the whole 
length and posteriorly broader than anteriorly. 
The immovable finger of the mandibles with lamina 
exterior, lamina interior plate-formed, at most with 
slight incisions. 
The lower side of the maxille lying in the same 
plane as the coxz of the legs.
