495. Homalota Philonthoides. 
Tlomalota Philonthoides, Woll., Ins. Mad. 551. (1854). 
Inhabits Madeira proper, occurring in sylvan spots of a lofty ele- 
vation. It approaches very closely, in size, outline, and sculpture, 
to the H. gregaria, which is so abundant along the edges of the 
streams in Porto Santo; nevertheless it is a little less shining and 
depressed than that species, its head and prothorax are a trifle 
smaller, its antenne are slenderer (especially at the base, where they 
are distinctly rufo-ferruginous), its pubescence is somewhat coarser, 
its elytra are scarcely more diluted in colouring than the rest of the 
surface, and its legs are usually entirely pale,—whereas in the gre- 
garia the femora are more or less infuscated.

Inhabits Madeira proper; abounding at the edges of the streams, 
and in other damp spots, at intermediate elevations. Since the pub- 
lication of the Jnsecta Maderensia I have forwarded specimens to 
Berlin, for examination by Dr. Kraatz; and since they appear to be 
specifically coincident with the palustris of Kiesenwetter, the name 
of currens has to be suppressed. 
497. Homalota Thinobioides. 
H. angusto-linearis valde depressa nigra subnitida pubescens sub- 
tilissime confertissimeque alutacea, capite confertim subpunctato, 
prothorace subquadrato profunde canaliculato, antennis gracilibus 
fuscis, pedibus brevibus saturate testaceis.

H. narrow and linear (the sides being almost parallel), exceedingly 
depressed, black, and densely clothed with a short and fine pubes- 
eence. Head, prothorax, and elytra but very slightly shining, and 
(appearing beneath the microscope) most closely and delicately 
alutaceous all over,—the head alone (which is rather large and 
subquadrate) being, in addition, densely (though lightly) pune- 
tulated. Prothoraxv about as wide as the head, subquadrate (being 
but slightly narrowed behind), and broadly channeled down the 
disk. Hlytra generally a trifle paler (or more fuscescent) than. the 
head and prothorax. Abdomen comparatively shining, and densely
