102 Mr. T. V. Wollaston on Additions to Madeiran Coleoptera. 
towards the lateral margins. Antenne brownish-piceous, being 
a little brighter at their base. Legs piceo-testaceous, with their 
tarsi pale. 
Except in its comparatively diminutive size, the present insect 
bears a considerable primd facie resemblance, in its general con- 
tour and posteriorly-truncated head, to the Xantholinus punctu- 
latus. Nevertheless, apart from the great differences of its 
punctation (which may be gathered from the above diagnosis), 
the generic characters of the Leptacini will of course at once 
separate it; and amongst these, the subulated apical joint of 
the palpi is perhaps the most apparent. Its discovery in Ma- 
deira is due to Mr. Bewicke, who has recently forwarded me five 
specimens which he captured, during the past summer, beneath 
hay-stack rubbish, at 8. Antonio da Serra. I should add that 
one of the Madeiran examples has likewise been carefully exa- 
mined by Mr. Janson, who agrees with me in referring it to the 
Staphylinus linearis, Grav.

Philonthus thermarum, Aubé, Ann. de la Soc. Ent. de France (2ime série), 
viii. 316 (1850). 
P. small, narrow, and black. Head and prothorax highly 
polished ; the former rather long and subquadrate, being straightly 
truncated behind ; the /atter more piceous than the head, and 
with a longitudinal series of four (or sometimes, apparently, 
five) punctures down either side of its disk, and with a few scat- 
tered ones between them and the edges. H/ytra paler than the 
head and prothorax, being more or less testaceo-piceous, and 
paler behind than in front; sparingly, but distinctly, punctu- 
lated. Antenne brown; their base and the legs testaceous. 
Two examples of the P. thermarum, Aubé, which agree pre- 
cisely with British ones in my possession, were captured by my- 
self, beneath vegetable refuse, near Funchal, during the spring 
of 1859. Their minute size, narrow outline, subquadrate head, 
and diluted elytra, in conjunction with the four (or sometimes
