Inhabits Madeira proper, oecurring in the dung of cattle at low 
and intermediate elevations. The sexes of this insect would appear 
to differ slightly in the structure of their antenne, which in the 
males (?) is rather longer and slenderer than in the females; and, 
according to Erichson, it was to the former that Mannerheim gave 
the name of exigua.

O. a little smaller, narrower, and more linear than the O. inflata ; 
also generally somewhat darker (or of a less brownish-piceous hue), 
and not quite so coarsely pubescent. Prothoraw rather less 
narrowed anteriorly than in that species. lytra with the sides 
a little more parallel than in the O, inflata, and about as broad as 
(instead of, as there, a trifle broader than) the prothorax ; con- 
jointly a good deal scooped-out behind (considerably more so than 
in that insect). Abdomen less perceptibly dilated at its apex than 
in the O. inflata. Antenne a little shorter, and more compact, 
than in that species, and with their apical three joints forming 
a rather more decided club; ferruginous: their base, and the legs, 
diluted-testaceous, 
Whilst compiling the Insecta Maderensia, I overlooked the present 
species amongst specimens of the following one. It is, I believe, 
rightly referred to the pusillima of Gravenhorst, as its ally is to the
