292 Mr. T. Vernon Wollaston on 
(Sp. 1297) Homalota putrescens. 
According to Dr. Sharp, “ pretty close to the boletobia, 
Thoms., but really distinct; the male characters are very 
curious.” 
(Sp. 1299) Homalota Waterhousit. 
Dr. Sharp remarks of this Canarian Homalota, “a dis- 
tinct species, its nearest ally known to me being my 
subeenea.” Fauvel indeed, from a cursory examination 
of one of my types, has stated that it is identical with 
the eneicollis of Sharp. But in that conclusion I think 
that he was somewhat hasty; and I may mention that 
Mr. Rye is clearly of the same opinion,—adding “‘ The 
H. Waterhousii, Woll., is undoubtedly very close to 
Sharp’s eneicollis (= wanthoptera,* Kby.), but I am 
nevertheless convinced that it is a good species. It is 
more engine-turned in the punctation of its elytra, and it 
is also narrower and more convex; its prothorax is 
rather less transverse ; and the apical joint of its antenna 
(in both sexes) is much shorter.”

Genus Pracusa. 
Erichson, Kif. der Mark Brand. 1. 370 (1837). 
Nine or ten examples of a small Staphylinid which I 
captured, during February of 1870, beneath the bark of 
a felled Spanish-chestnut tree, at ‘‘ the Mount” (above 
Funchal), in Madeira, have been identified by Dr. Sharp 
with the British Placusa infima—which he informs me 
he has taken under precisely similar circumstances in 
England ; and I will therefore record the species, briefly, 
as follows :— 
Placusa impfima. 
P. depressiuscula, subopaca, densissime ruguloso-punc- 
tata, minute griseo-pubescens, nigra; elytris (praesertim 
* Nec merdaria, Kraatz,—erroneously identified in Waterhouse’s Ca- 
talogue with Kirby’s vanthoptera.
