A NEW SUMATRAN SPECIES 
OF THE RHYNCHOPHOROUS GENUS OMOTEMNUS 
DESCRIBED BY 
C. RITSEMA Cz. 
Omotemnus Stolzi, n. sp. co and Q. 
One { and three 99 from Solok (Highlands of Padang: 
West Sumatra) presented to the Leyden Museum by Mr. P. 
O. Stolz. 
Length (without rostrum): of the / 35 mm., of the 
QQ 38 and 32 mm.; length of the rostrum in the { 
10 mm., in the OQ resp. 12 and 10 mm.; greatest breadth 
(at the shoulders) in the © 14,5 mm., in the QQ resp. 
16 and 14 mm. 
Upper surface (the pygidium included, but with the 
exception of the head and rostrum) dull, velvetlike '). 
Under surface, antennae and legs glossy. 
Entirely black (included the pilosity on the legs and 
on the apex of the last abdominal segment) except the 
pronotum which is red, margined with black anteriorly, 
the basal lobe black and two ovate, slightly obliquely 
placed black spots just before the middle; these spots seem 
to be variable in size, as in one of my four specimens (a 9) 
they are much reduced, almost punctiform, so that perhaps 
specimens will be found in which these spots are entirely 
absent. The club of the antennae is more or less dark 
pitchy brown, and the opaque truncation pale fulvous. In 
one of the two smaller females (that with the reduced 
thoracical spots) a small red spot is. present just before 
the interocular pit. 
In the © the rostrum is (seen sideways) regularly 
1) In the female specimens a glossy, minutely punctured, narrow bifurcate 
streak is present along the middle of the anterior third of the pronotum.
