Mr. T. V. Wollaston on Additions to Madeiran Coleoptera. 51 
January 1859, in abundance, beneath stones, close to the shingly 
beach of the low calcareous promontory at Porto da Cruz, in the 
east of Madeira proper; and I have great pleasure in dedicating 
it to my excellent friend the Bardo do Castello de Paiva, to whose 
kindness I am indebted for much valuable assistance in procur- 
ing for me, at various times, specimens of Madeiran Coleoptera, 
and whose botanical researches, both in Madeira and the Cana- 
ries, are already well known. 
Fam. Staphylinide. 
(Subfam. ALEOCHARIDEs.) 
Genus Tacuyvsa. 
Erichson, Kaf. der Mark Brand. i. 307 (1837). 
Tachyusa maritima, n. sp. 
T. depressa, minute punctulata, subopaca, nigra et dense cinereo- 
ubescens ; capite transversim subquadrato ; prothorace late cana- 
iculato, postice angustiore ; elytris vix picescentioribus ; antennis 
pedibusque dilute testaceis, illis gracilibus, apicem versus vix 
obscurioribus. 
- corp. lin. 14. 
Habitat Maderam, rarissima; in salinis lapidosis juxta mare ad 
Sanctum Vincentium, inter lapillos velocissime cursitantia, duo 
- Specimina mense Decembri a.p. 1858 collegi. 
Tf. depressed, dull-black, minutely punctulated, subopake, 
_ and densely clothed with cinereous pubescence. Head trans- 
versely subquadrate, being straightly truncated behind, and with 
the forehead slightly channeled down the centre. Prothorar a 
little narrowed posteriorly, and with a wide, but not very deep, 
channel down its disk. Elytra just perceptibly more picescent 
than the head and prothorax. Abdomen rather more shining. 
Antenne slender, and a little longer than the head and pro- 
thorax ; testaceous, being but very slightly. more obscured to- 
wards their apex. Legs diluted testaceous. 
Two specimens of the present very distinct Tachyusa were 
captured by myself, during December 1858, below high-water 
mark, on the shingly beach at Sao Vicente, at the exact point 
(close to the chapel-rock) where the stream empties itself into 
the sea. It would appear to be the representative of the 7. 
uvida of more northern latitudes, being somewhat intermediate 
between that species and the 7. sulcata. It is, however, rather 
smaller than the former, with its antenne shorter, more slender, 
and (together with the legs) paler, and its head is not quite so 
long ; whilst from the latter it recedes (inter alia) in being con- 
siderably larger and with altogether longer limbs,—the antennal
