176 HETEROMERA. 
straight behind, the surface punctured like that of the head ; elytra nearly twice as wide as the pro- 
thorax, parallel to about the middle, densely and coarsely punctured, with a shallow oblique depression 
extending from the shoulders downwards ; legs ( 2 ) moderately long, rather slender (the femora included), 
black, the tarsi entirely flavo-testaceous, the tibie almost straight, the hind pair with a matted spine-like 
tuft of fulvous hairs at the outer apical angle. 
Length 23 millim. ( 9.) 
Hab. Guatemaua, Cerro Zunil 4000 feet (Champion). 
Two examples, both females; the male doubtless has the hind femora incrassate. 
Allied to X. humeralis, but smaller and shorter; the elytra black, with a transverse 
median band (not reaching the suture) of ashy pubescence, the suture also clothed 
with similarly-coloured pubescence ; the tarsi entirely flavo-testaceous. 
12. Xylophilus v-notatus. (Tab. VIII. fig. 12, 2.) 
Moderately elongate, subparallel, rather broad and robust, opaque, thickly clothed with fine, semierect 
pubescence; brownish-black, the elytra each with a long narrow V-shaped mark (forming together a 
perfect W) of whitish silky pubescence towards the suture about the middle, this mark connected internally 
with a similarly-coloured streak of pubescence extending along the suture and externally with a large sub- 
triangular lateral patch (the latter extended along the lateral margin to the apex), the base narrowly and the 
apex more broadly clothed with whitish pubescence, for the rest clothed with dark brownish pubescence, the 
prothorax also with whitish pubescence at the sides. Head moderately large, densely and finely punctured ; 
eyes ( 2 ) hairy, rather large, coarsely granulated, deeply emarginate, narrowly separated, the head broadly 
extended on either side behind them and rounded externally ; antenne ( ? ) piceo-ferruginous, the apical 
three joints darker, densely pubescent, about reaching the middle of the elytra, exceedingly stout, widening 
outwardly, joints 2 and 3 subequal, 4 a little longer than 3, 4-10 gradually becoming shorter and wider, 
7 and 8 about as broad as long, 9 and 10 transverse, 10 strongly so, 11 a little narrower than, and nearly 
twice as long as, 10, short, ovate; prothorax narrower than the head, rather convex, as long as broad, the 
sides rounded and converging in front, straight behind, the surface punctured like that of the head ; elytra 
.about twice as wide as the prothorax, parallel in their basal half, with an oblique depression extending 
from the shoulders downwards, densely and coarsely punctured; legs ( 2 ) moderately long, rather slender 
(the femora included), piceous, the four anterior femora fusco-ferruginous, the tarsi entirely testaceous, 
the tibie almost straight, the hind pair with a matted spine-like tuft of fulvous hairs at the outer apical 
angle. 
Length 2? millim. ( 2.) 
Hab. Guatemata, Cerro Zunil 4000 feet (Champion). 
One female example only of this very distinct species was obtained. Allied tp 
X. fiavitarsis ; but larger and rather more elongate, the elytra with a very acutely 
angulated median fascia of silky whitish pubescence and the apex and lateral margins 
also clothed with similarly-coloured pubescence. The North-American X. nedulosus, 
Lec., seems to be an allied species; but it differs from X. v-notatus in having the 
base of the elytra reddish-brown. 
13. Xylophilus 2 
Hab. Guatemata, San Gerénimo (Champion). 
A single female example of a species closely allied to X. flavitarsis and X. v-notatus, 
the head of which is unfortunately missing. The insect is blackish-brown in colour;
