METOPODONTUS SPECTABILIS. 183 
NOTE XXXIII. 
A CLADOGNATHID WITH FIVE PUBESCENT 
LEAFLETS IN THE CLAVA OF THE ANTENNAE 
(Coleoptera: Liucanidae) 
DESCRIBED BY 
C. RITSEMA Cz. 
The Stagbeetle described in the following lines and be- 
longing to the genus Metopodontus of the subfamily Clado- 
gnathinae is very interesting by having five pubescent 
leaflets in the clava of the antennae. In all other known 
species of this subfamily the number of these leaflets is three. 
This is, as far as I know, the second example of an in- 
constant number of leaflets in the species of one and the 
same genus of the Lucanidae (Lucanus and Metopodontus). 
In coloration as well as in general form the new species, 
for which I propose the specific title spectabilis, resembles 
Metopodontus cinctus Montr. 
Metopodontus spectabilis, nov. spec. 
Length of the two males which I have before me and 
which are of different development: 35 mm. and 26 mm. 
(without mandibles); length of the mandibles resp. 7 mm. 
and 4,5 mm. — Mandibles, head and prothorax dull black, 
the latter laterally with a longitudinal fulvous spot which 
is constricted about the middle of its length. Elytra glossy 
black, surrounded (except at the base) by a broad yellow 
vitta which does not invade the extreme rim and which 
obliquely narrows towards the shoulders; a dark chestnut 
streak (only visible under certain lights) runs along the 
middle and is divided by the suture. Underneath and legs 
black, the metasternum on both sides with a large reddish 
brown spot, all the femora with a red spot, 
The mandibles are nearly straight, slightly curved near
