MADEIRAN COLEOPTERA. 187 
developed state of the O. Jansoni, peculiar to the loftier portions of 
the sylvan regions; nevertheless since it is exceedingly distinct from 
the normal phasis of that insect, I imagine that it would be scarcely 
safe to identify it therewith; and I would regard it therefore as a 
nearly allied species of the same (geographical) type. Three speci- 
mens were captured by myself in the north of Madeira proper, during 
the summer of 1855,—namely, one at the Lombo dos Pecegueiros, 
and two from amongst damp moss growing on the trunks of the trees 
at the Cruzinhas (more than 4000 feet above the sea): and another 
has been recently communicated by Mr. Mason. 
530, Othius Jansoni. 
Othius Jansoni, Woll., Ins, Mad. 576 (1854). 
Inhabits Madeira proper; occurring in the moist ravines of inter- 
mediate altitudes, and having apparently a rather lower range than 
the O..vestitus. As already implied, itis rather smaller and narrower 
than that insect ; its head is a trifle less robust ; and its elytra, which 
are occasionally (var. 3) quite pale, are a little more piceous (or less 
strictly fuscescent), not quite so much developed, and, together with 
the abdomen (which is rather less expanded behind the middle, and 
more acuminated at its apex), less densely pubescent. 
531. Othius brevicornis, n. sp. 
O. piceo-niger angustulus nitidus, capite prothoraceque politissimis 
(illo parvusculo), elytris parvis picescentibus, antennis pedibusque 
pallido-ferrugineis, illis brevibus. 
Long. corp. lin. 44. 
O. similar to the O. Jansoni, but a trifle narrower, with its head a 
little less developed and just perceptibly more ovate, its elytra 
even still more abbreviated, its legs a shade paler, and its antenne 
distinctly shorter. 
Were it not for the slight structural differences, in the elytra and 
antenne, of this insect (which are distinctly shorter), I should have 
regarded it as the Dezertan state of the O. Jansoni,—which, in gene- 
ral aspect, it very much resembles; but since such a concession 
would perhaps be scarcely consistent with other conclusions, else- 
where arrived at, I have been compelled to regard it as another ex- 
ponent of the Madeiran (Othius) type. A single example (now in 
the British Museum) was captured by myself, beneath a stone, at the 
roots of the coarse grass, on the extreme summit of one of the loftiest 
peaks of the Dezerta Grande (towards the south of the island), early 
in June 1855,
