XYLOPHILUS. 179 
The eyes are very coarsely granulated, the head very narrowly extended on either side 
behind them : 
18. Xylophilus quadrisignatus. (Tab. VIII. fig. 13, 3.) 
Rather short, convex, shining, thickly clothed with long, semierect, ashy pubescence ; black, the elytra each with 
two large testaceous spots, one at the shoulder and the other near the apex, the latter not quite reaching 
the suture (in one example still larger and extending to the apex). Head large and broad, thickly and 
somewhat coarsely punctured ; eyes (3) very hairy, deeply emarginate, very coarsely granulated, large, 
narrowly separated, the head narrowly extended on either side behind them and with rather prominent 
hind angles ; antenne ( ) moderately long, rather stout, thickly pubescent, ferruginous, the basal joint 
black, joint 2 only a little shorter than 3, 3-10 very gradually increasing in width, longer than broad, 
10 nearly as broad as long, 11 much stouter than, and fully twice as long-as, 10, ovate, acuminate ; pro- 
thorax considerably narrower than the head, convex, as long as broad, the sides rounded and converging 
in front, almost straight behind, the surface thickly and somewhat coarsely punctured ; elytra at the base 
about one half broader than the prothorax, moderately long, rather convex, a little rounded at the sides, 
widest at the middle, obliquely depressed on either side below the shoulders, thickly and coarsely punc- 
tured ; legs stout, piceous, the base and apex of the tibize-and the tarsi testaceous; the hind femora (¢ ) 
much thickened and subangularly dilated on the outer side beyond the middle; the anterior tibie (3) 
slightly curved without, sinuous within, and with a short tooth on the inner side at the apex. 
Length 2 millim. (¢.) 
Hab. Panama, Bugaba, Volcan de Chiriqui (Champion). 
Three male examples. Less parallel and more convex than X. cinctipennis, black, 
the elytra with a large testaceous spot at the shoulder and another near the apex. The 
pubescence is long, semierect, and rather coarse. The hind femora in the male are 
much thickened and somewhat angularly dilated on the outer side beyond the middle, 
the inner side being slightly sinuate. 
19. Xylophilus cinctipennis. 
Moderately elongate, subparallel, shining, thickly clothed with long, semierect, ashy pubescence ; the head and 
prothorax black, the latter sometimes reddish ; the elytra testaceous, with a transverse more or less curved. 
black or piceous fascia on either side at the middle, the fascia not reaching the suture and extending 
upwards along the lateral margin, and sometimes with the scutellar region, apex, or the suture, very 
narrowly, infuscate. Head large and broad, finely and somewhat thickly punctured; eyes very large, 
very coarsely granulated, deeply emarginate, thickly clothed with long erect pubescence, narrowly separated 
in the male, more distant in the female, the head extended on either side behind them and with prominent 
hind angles ; antenne variable in colour, varying from black with the apical joint ferruginous to ferru- 
ginous with the two basal joints black—( ¢ ) rather stout, moderately long, joint 2 a little more than half 
the length of 3, 3-10 differing very little in length or width, longer than broad, 11 twice as long as 10, 
ovate, acuminate—(  ) much shorter, joints 4-10 transverse; prothorax convex, narrower than the head, 
about as long as broad, shorter in the female, the sides rounded and converging in front, straight behind, 
the surface closely and somewhat coarsely punctured ; elytra very much wider than the prothorax, sub- 
parallel in their basal half, with an oblique depression extending downwards from the shoulders towards 
the suture, closely and somewhat coarsely punctured ; legs moderately long, rather stout, variable in 
colour—testaceous with the tibiee (except at the base and apex) black and the outer halves of the femora 
darker, or entirely testaceous; the hind femora clavate in both sexes; the anterior tibie a little curved 
without, slightly sinuous within, and furnished with a short fine tooth on the inner side at the apex, in 
the male. 
Length 2-23 millim. (¢ 2.)
