113. Nitidula colon*. 
NV. oblongo-ovata fusco-nigra, prothorace antice profunde emarginato, 
in disco postico bifoveolato, ad latera late ferrugineo, elytris ubique 
sed preesertim pone medium testaceo-maculatis.

N. oblong-ovate, being of the same form as the NV. discoidea (though 
more pubescent, and a little more coarsely punctured) ; brownish- 
black. Prothorav deeply emarginated in front, short and trans- 
verse, the sides and the anterior margin generally broadly and 
brightly ferruginous ; its surface not quite so uneven as that of 
the last species, though with the two fovez on the centre of its 
hinder disk more rounded and deep. Elytra with several small 
and obscure spots towards the base and apex, and a larger, brighter 
and well-defined one on the hinder disk of each (and confluent at 
the suture, so as to form an irregular postmedial fascia), testaceous. 
Limbs brownish-ferruginous. 
A specimen of the common European J. colon (now in the British 
Museum) was detected by myself, during the summer of 1855, in a
