198 MADEIRAN COLEOPTERA. 
Ribeira da Janella and Porto Moniz. It is evidently a truly in- 
digenous insect, and would appear to reside in the dampest spots, 
exposed to the constant spray of the waterfalls,—a circumstance 
which has suggested its specific name. It is closely related to the 
European SS, cicindeloides, of which it may be regarded as the 
Madciran representative. Nearly as it approaches that species, how- 
ever, in general aspect, it cannot be looked upon, I think, as a 
geographical modification. of it,—presenting too many characters 
(however small) which could scarcely, in conjunction, be the result of 
local influences of any kind. Thus, it is rather smaller and narrower 
than its European ally, zts elytra are (in proportion) distinctly shorter 
and a little more ventricose, 1ts abdomen is rather more acuminated, 
and its antennee are entirely pale. 
561. Stenus fulvescens, n. sp. 
Stenus Heeri, var, 8, Woll., Ins. Mad. 600 (1854). 
Inhabits the mountains of Madeira proper, occurring beneath stones 
in the damp sylvan districts of a high elevation: rare. In the _ 
Insecta Maderensia I regarded this species as a large state, or variety, 
of the S. Heert; but a further acquaintance with it has convinced me 
that it is truly distinct therefrom. Thus, it is not only (on the 
average) “rather larger, and with the antenne, palpi and legs pro- 
portionably a little longer, and of an altogether paler hue,’’ but it is 
also more densely clothed with fulvescent pubescence, its punctuation 
is a little rougher, and the surface of its elytra is somewhat more — 
uneven. 
562. Stenus Heeri. 
Stenus Heeri, Woll., Ins. Mad. 600 (1854). 
Inhabits Madeira proper; occurring in similar spots as the last 
species, and often in company with it. Rare.
