and with their exterior angle a good deal prominent) have a curved 
and powerful inner spur,—usually very evident. In their habits the 
species are either subcortical or granivorous, possessing a good deal 
in common with Tribolium and Cerandria,—and even with the 
Necrophagous Trogosite and Lycti. 
437. Hypophleus ambiguus, n. sp. 
H. lineari-elongatus rufo-ferrugineus nitidus, capite prothoraceque 
subtiliter punctatis, elytris subfusiformibus basi truncatis, leviter 
punctato-striatis, interstitiis minutissime uni-seriatim punctulatis. 
Long. corp. lin, 11. 
H. linear-elongate and narrow, bright rufo-ferruginous, and shining. 
Head and prothorax less closely and coarsely punctured than in 
Tribolium ferrugineum ; the former with the forehead rounded and 
elevated along its anterior edge, but very much less expanded be- 
fore the eyes than in that insect,—scarcely indeed projecting so 
far as them; and with the clypeus well defined and semicircular, 
being raised anteriorly (which is not the case in Tribelium) con- 
tinuously with the rest of the forehead at its edges: the latter 
quadrate, slightly widened in front, and with its posterior angles 
almost right angles. /ytra subfusiform, and truncated at the 
base,—being rather broader a little before the middle than else- 
where; lightly punctate-striated, and each of the interstices with 
a longitudinal row of very minutely impressed points. Legs, and 
the apical joint of the antenne, a trifle paler than the rest of the 
surface. 
Two examples of the present Hypophleus were detected by Mr. 
Mason during 1856, but in what part of the island I am not able to 
state,—further than that they were mixed up with insects from the 
upland region of the Fanal. Being thus however associated, I should 
not hesitate to regard them as natives of that elevated district, did I 
not feel it possible that (if there obtained) they may have been acci- 
dentally conveyed thither, amongst provisions, from Funchal,—and 
especially so since the European H. depressus, to which the ambiguus 
is closely allied, is eminently granivorous in its habits, attaching 
itself to granaries and such-like spots: and I am further confirmed 
in this hypothesis by finding in the same bottle specimens of the 
Sitophilus Oryze, which clearly must have been captured either im or 
around his tent. It differs from the H. depressus, Fab., in being a 
good deal smaller, somewhat narrower in proportion, and in its pro- 
thorax being less expanded in front.
