XYLOPHILUS. . 177 
the elytra with an ashy-pubescent, testaceous, common, triangular patch towards the 
apex (much as in X. lacertosus) and a transverse median band of ashy pubescence, the 
latter connected externally with a stripe of similarly-coloured pubescence which extends 
from the base to the apex. The hind tibia have a matted spine-like tuft of fulvous 
hairs at the outer apical angle as in the female of X. flavitarsis. 
14. Xylophilus laticeps. 
Moderately elongate, convex, black, shining, thickly clothed with long, semierect, ashy pubescence. Head very 
large and broad, thickly and not very finely punctured ; eyes ( ¢) very hairy, coarsely granulated, very 
deeply emarginate, large, somewhat widely separated, the head rather broadly and subangularly extended 
on either side behind them; palpi piceous; antenne (¢) very pubescent, moderately long, stout, black, 
the tip of the last joint ferruginous, joint 2 rather more than half the length of 3, 3-10 about equal in 
length, longer than broad, 5-10 scarcely differing in width, 11 a little stouter and much longer than 10, 
ovate, acuminate; prothorax convex, much narrower than the head, nearly as long as broad, the sides 
rounded and converging in front, almost straight behind, the surface thickly and somewhat coarsely 
punctured ; elytra rather short, much wider than the prothorax, convex, somewhat rounded at the sides, 
widest a little below the base, thickly and rather coarsely punctured ; legs ( ¢ ) stout, brownish-black, the 
tarsi fusco-testaceous, the hind femora moderately clavate, the anterior tibize curved without, sinuous 
within, and with a short tooth on the inner side at the apex. 
Length 2-24 millim. (¢.) 
Hab. Mexico, Teapa in Tabasco (H. H. Smith) ; Guatemata, El Reposo 800 feet 
(Champion). 
Two examples from the Pacific slope of Guatemala and one from the Atlantic slope 
of Southern Mexico, all males. These differ from the same sex of the following 
similarly-coloured species in their very large and broad head, somewhat widely-separated 
eyes, and stout antenne. ‘The head is rather broadly and somewhat angularly extended 
on either side behind the eyes. 
15. Xylophilus atricolor. 
Rather short, convex, black, shining, thickly clothed with long, semierect, ashy pubescence. Head moderately 
large, finely and not very closely punctured; eyes very hairy, coarsely granulated, large, deeply emarginate, 
narrowly separated in the male, more distant in the female, the head narrowly extended on either side 
behind them and with slightly prominent hind angles ; palpi testaceous; antenne very pubescent, rather 
slender, black, the last joint ferruginous at the tip—( ¢) moderately long, joint 2 considerably shorter 
than 3, 3-10 increasing a little in width but about equal in length, longer than broad, 11 stouter than, and 
more than twice as long as, 10, ovate, acuminate—( Q ) much shorter, joints 6-10 transverse ; prothorax 
convex, a little narrower than the head, about as long as broad, the sides rounded and converging in front, 
nearly straight behind, the surface thickly and somewhat coarsely punctured, the disc obsoletely canali- 
culate behind ; elytra convex, rather short, at the base about one half broader than the prothorax, a little 
rounded at the sides, widest at the middle, thickly and rather coarsely punctured ; legs stout, black, the 
tarsi entirely flavo-testaceous, the hind femora moderately clavate in both sexes; the anterior tibie on 
the outer side curved to beyond the middle and then abruptly bent inwards, on the inner side a little 
sinuate and at the apex furnished with a sharp tooth, in the male. 
Length 13-2 millim. (¢ Q.) 
Hab. Panama, Bugaba (Champion). 
Two examples. ‘The more slender antenne, narrower head, more approximate eyes,
