XYLOPHILUS. 17 
7, Xylophilus lacertosus. (Tab. VIII. figg. 7,3; 7a, hind leg.) 
Moderately elongate, subparallel, broad, very robust, opaque, very densely clothed with rather long, semierect 
pubescence ; the head and prothorax black or brownish-black, the former more or less ferruginous in 
front, and the latter, in one example, indeterminately lighter at the sides; the elytra reddish- or piceous- 
brown, or piceous with the base and shoulders brownish, with a rather broad, blackish stripe on either side 
of the suture extending from the base to far beyond the middle, this stripe limited posteriorly by a 
common triangular, ashy-pubescent, fusco-testaceous subapical patch, from which a line of ashy 
pubescence runs up the suture, and another (but interruptedly) along the outer edge of the sutural stripe, 
a similar streak of ashy pubescence extending from the shoulders downwards, and more or less confluent 
with the triangular patch. Head large and broad, very densely and roughly punctured ; eyes very hairy, 
moderately large, narrowly separated in the male, more distant in the female, coarsely granulated, deeply 
emarginate, the head in both sexes somewhat broadly extended on either side behind them and rounded 
externally ; antenne ferruginous, the apical joint usually darker, very hairy, in both sexes exceedingly 
stout from the base—( ¢ ) very long, widening a little outwardly, joint 2 more than half the length of, 
and a little stouter than, 3, 3-8 much longer than broad, subequal, 9 and 10 a little shorter, 10 as 
broad as long, 11 fully three and a half times as long as 10, slightly curved—{ @ ) shorter, more widened 
outwardly, the apical joint ovate, nearly twice as long as the tenth ; prothorax narrower than the head, 
rather convex, as long as broad (a little longer in the male than in the female), the sides rounded and 
narrowing in front and almost straight behind, the surface punctured like that of the head ; elytra broad, 
parallel to about the middle, with a broad, shallow, oblique depression extending from the shoulders 
downwards, the suture also depressed at the base, the surface densely, coarsely, and rather shallowly 
punctured ; legs densely pubescent, moderately long, reddish-testaceous, the apical halves of the tibie 
(and sometimes the femora in the middle) piceous, the tarsi flavo-testaceous ; the four anterior tibie 
sinuously curved in both sexes, strongly so in the male, the front pair with a long sharp tooth on the 
inner side at the apex in the male, the hind pair with a matted tuft of coarse fulvous hairs at the outer 
apical angle in the female ; the femora rather slender, the hind pair in the male very broadly widened, 
grooved on their inner side, and the concavity filled with a dense row of short fulvous hairs. 
Length 3-34 millim. (3 9.) 
Had. Guatemata, San Lucas Toliman 5000 feet, San Gerdnimo 3000 feet (Champion). 
One male and three female examples. The large size, robust build, exceedingly 
stout antennee, the apical joint of which is very elongate and subcylindrical in the male, 
peculiar elytral markings, &c., distinguish this remarkable species from all others of 
the genus here enumerated. In the excavate and densely ciliate inner margin of the 
hind femora in the male it resembles the following, X. forticornis. The four anterior 
tibiee are sinuously curved in both sexes, very strongly so in the male, the hind pair 
having a thick tuft of fulvous hairs at the outer apical angle in the female. ‘The apical 
joint of the antenne is ovate in the female and elongate and a little curved in the 
male. This is one of a group of species somewhat numerously represented in Central 
America, and, like the following, possesses very peculiar sexual characters. 
8. Xylophilus forticornis. (Tab. VIII. figg. 8, ¢ ; 8a, hind leg.) 
Rather short, subparallel, broad, robust, opaque, very densely clothed with rather long, semierect, silky pube- 
scence ; the head and prothorax brownish-black, or ferruginous much stained with piceous, the anterior 
part of the head always ferruginous ; the elytra brownish- or fusco-testaceous, with a broad, ill-defined 
piceous-brown fascia before, and a rather narrower one below the middle, the pubescence between and 
beyond these fasciz yellowish or ashy, and forming a more or less distinct transverse median band and 
an apical patch (this latter sometimes showing a tendency to form a common triangular spot just below
