168 MADEIRAN COLEOPTERA. 
The genus Huplectus is mainly distinguished by the elongated, 
narrow, and depressed bodies, and the fusiform terminal articulation 
of the maxillary palpi, of the species which it embraces,—and which 
have their (11-jointed) antenne inserted in a groove under the 
margin of the forehead, and their tarsal ungues single. 
480. Euplectus intermedius, n. sp. 
E. rufo-testaceus nitidus pubescens vix punctatus, capite lato antice 
leviter transversim impresso necnon in fronte bifoveolato, pro- 
thorace in disco foveola impresso, basi profundius trifoveolato, 
elytris brevissimis, antennis pedibusque testaceis. 
Long. corp. lin, #3. 
E. narrow, rather depressed, rufo-testaceous, slightly shining, pubes- 
cent, and almost impunctate,—some rather large but shallow 
punctures being alone perceptible at the sides of the head. Head 
wide; truncated, and rather convex, behind; with a lightly im- 
pressed transverse line between the antenne, and two longitudinal 
impressions on the forehead,—which are suddenly shallower an- 
teriorly, but deeply and abruptly commenced, causing two. small 
rounded fovez to appear on its disk. Prothorav with a narrow, 
abbreviated, central foveolet in front, and with three larger and 
deeper ones (which are joined by a transversely impressed line) 
behind. lytra very short, with a line on each alongside the 
suture, and a longitudinal depression at either shoulder,—dcep at 
its commencement, but beeeming gradually evanescent about the 
middle. Abdomen with the first three segments broadly margined, 
and reflexed, at the sides. Limbs testaceous. 
The present Huplectus combines, to a certain extent, the characters 
of the #. Karstenw and signatus of more northern latitudes, agreeing 
with the former in its broad head and more lightly impressed fovee, 
but in its less parallel shoulders and almost unpunctured surface, 
with the latter. Its elytra, however, are rather shorter than in 
either of those species, and its frontal foyeolets are rounder and more 
minute. Its head, although broad, is not quite so wide as that of the 
Karstenii ; and its frontal foveolets, although smaller than in that 
insect, are better defined. From the signatus, on the other hand 
(with which it better agrees in general contour), it may be at once 
recognized by its larger and differently shaped head, by its fovee 
being very much shallower, its pubescence a little less silvery, its’ 
surface somewhat duller, and by its antenne being perhaps not quite 
so robust. A single specimen was detected, by myself, beneath the 
bark of a dead tree in the damp forest-district of the Lombo dos 
Pecegueiros (in the north of Madeira proper), during July 1855; 
and three more have been subsequently captured by Mr. Bewicke, at 
Campanario.
