COLEOPTERA a

Coelosterna Stolzi, nov. spec. Q. 
Length from the frontborder of the antennary tubers to 
the apex of the sutural spine at the end of the elytra 
32,5 mm.; length of the elytra 24,5 mm., breadth of the 
elytra at the shoulders 11,5 mm. 
Of a rather broad form in this genus, the elytra being 
almost parallelsided and at the apices but slightly convex. 
Black, covered with a dense cinnamon coloured pubes- 
cence which is somewhat yellowish on the legs and on 
the undersurface and greyish on the tarsi above; the 
pubescence is very thin along the middle of the face and 
between the antennary tubers; it is absent on the space 
between the underlobe of the eyes and the base of the 
mandibles and on the declivous portion of the elytra in 
front of the shoulders; opposite to the last-named bare 
spot a small spot of a grey pubescence is visible on the 
base of the pronotum just behind the lateral spines; the 
antennae, which are incomplete in my specimen as in both 
the four apical joints are wanting, are sooty black above 
and covered below with a delicate greyish pubescence which 
forms a narrow ring at the extreme base of the joints;
