XYLOPHILUS. 189 
head, about as long as broad, the sides dilated in front, compressed behind this, and thence to the base 
parallel or very slightly converging, the base feebly sinuate on either side, the disc with a short, deep, 
oblique impression on each side near the base, the impressions confluent behind (in some specimens forming 
a deep transverse pit, and filled with whitish pubescence), the surface closely and finely punctured ; elytra 
long and subparallel, widest beyond the middle, about twice as wide as the prothorax, broadly transversely 
depressed below the base, very closely and finely punctured; beneath black, densely pubescent; legs 
varying in colour from piceous-brown to testaceous, long and slender, the tibie almost straight, the hind 
femora simple (but a little stouter in the male than in the female); the hind tibie feebly dilated on the 
inner side before the middle in the male. 
Length 23-23 millim. (¢ 9.) 
Hab. GUATEMALA, Quiche Mountains 7000 to 9000 feet (Champion). 
Numerous examples of both sexes of this handsome species were beaten from the 
branches of oak-trees on the mountain-slope above the village of Chimente, in the Los 
Altos region of Guatemala. Allied to X. argentatus and X. suturalis, but differing 
greatly from either. The species may be at once known from all others of the genus 
by the elytra each having an oblique white or yellowish-white streak on the disc and a 
large similarly-coloured oblique H-shaped mark near the apex, the inner portion of 
the latter curved inwards behind and confluent with the corresponding portion of the 
one on the opposite elytron at the suture. In one female specimen the brownish 
pubescence of the elytra is paler and the white marks are edged with dark brown. 
The colour of the legs and antenne is variable, as is also that of the darker portion of 
the elytral pubescence. The eyes are almost entire. In one abraded, apparently 
immature, example the head and thorax are quite black, the elytra, legs, and antenne 
are testaceous, and the head is shining, smooth, and almost impunctate. 
A. anthicoides much resembles an Anthicus. 
35. Xylophilus stigmosus. (Tab. VIII. fig. 27.) 
Broad, rather short, opaque, brownish-testaceous, densely clothed with fine, silky, closely appressed pubescence ; 
the head, except in front, piceous-brown, the eyes black; the prothorax with a narrowly separated reddish- 
brown triangular patch on each side of the middle of the disc, for the rest clothed with whitish pubes- 
cence ; the scutellum whitish; the elytra with a rather large oblong dark brown spot on either side of 
the suture at the base and a broad similarly-coloured zigzag fascia just below the middle (extending 
nearly to the lateral margin), for the rest clothed with whitish pubescence. Head large and broad, finely 
and rather sparsely punctured ; eyes small and prominent, entire, rather finely granulated, very widely 
separated, distant from the base of the head, the sides of the latter obliquely converging behind them ; 
antenne testaceous, clothed with long hairs, long and slender, the apical three joints stouter, joint 2 
stouter and only a little shorter than 3, 3-8 elongate and subequal, 9 and 10 wider, much longer than 
broad, 11 longer and stouter than 10, ovate, acuminate ; prothorax broader than long, a little narrower 
than the head, somewhat flattened on the disc, the sides dilated in front, compressed behind this, and 
thence to the base almost straight, the‘base feebly sinuate on either side, the surface closely and finely 
punctured; elytra at the base about one half broader than the prothorax, gradually widening to beyond 
the middle, the sides a little rounded behind but straight in front, broadly transversely depressed below 
the base, closely and finely punctured ; beneath piceous-brown, densely pubescent; legs long and slender, 
fusco-testaceous, the hind femora little darker, the tibie almost straight. 
Length 14 millim.
