194 MADEIRAN COLEOPTERA. 
L. testaceo-rufous, slightly shining, and clothed (at any rate on the 
elytra) with a decumbent griseous pubescence. Head and pro- 
thorax faintly alutaceous, when viewed beneath the microscope : 
the former large and subquadrate; very remotely, but deeply 
punctured ; with a minute and obscure black spot on either side 
of the forehead ; and with the eyes small, and scarcely at all pro- 
minent: the latter subquadrate, and broad anteriorly ; more finely, 
and more closely, punctured than the head ; the punctures shallow 
and ill-defined. lytra much abbreviated. Abdomen blackish 
towards its base, but paler posteriorly. Antenne brownish-ferru- 
ginous, with their apical and two basal joints rufo-testaceous. Legs 
robust, and testaceous. 
A most distinct and interesting Lithocharis, and truly indigenous 
to these islands,—the single specimen which has hitherto come under 
my observation having been captured by myself, from beneath a 
stone, in the upland forest-region of the Cruzinhas (nearly 5000 feet 
above the sea) during July 1855. Its greatly abbreviated elytra, 
anteriorly widened prothorax, and almost rufous hue, will, apart 
from its peculiarities of sculpture, &c., at once distinguish it from its 
allies.

Inhabits all the islands of the Madeira group, except the Northern 
Dezerta (on which, at least, it has not yet been detected) ; occurring 
beneath stones, in grassy spots, at intermediate elevations. 
552. Lithocharis debilicornis, n. sp. 
L. rufo-testacea subnitida, capite magno quadrato pubescente, pro- 
funde sed remote punctato, oculis parvis prominentibus, prothorace 
densius sed minus profunde subpunctato, subrotundato-quadrato, 
abdomine paulo obscuriore, elytris, antennis (brevissimis) pedi- 
busque testaceis. 
Long. corp. lin. 11. 
L. rufo-testaceous, slightly shining, and less pubescent (except on 
the head, which is more so) than any of the other species. Head 
and prothorax subalutaceous: the former quadrate, being suddenly 
- and greatly truncated behind; remotely, but rather deeply pune- 
tured ; with a very minute, and hardly distinguishable, black spot 
on either side of the forehead; and with the eyes small, and very 
prominent: the /atter roundish-quadrate; more finely, and more 
closely, punctured than the head; the punctures shallow, and 
exceedingly ill-defined. H/ytra paler than the head and prothorax,
