170 HETEROMERA. 
towards the suture, the suture also depressed at the base, the surface slightly shining, densely and 
coarsely punctured, the punctures finer at the extreme base; legs long and slender, the hind femora 
incrassate, testaceous, the hind femora towards the apex and the hind tibie infuscate, the tarsi flavous. 
Length 3 millim. (¢.) 
Hab. GUATEMALA, Quiche Mountains 8000 feet (Champion). 
One male example. Smaller and less elongate than X. /labellatus; the antennze 
considerably shorter and much paler in colour; the head smaller; the eyes not so 
large, more finely granulated, and separated by a narrow space on the vertex (in 
X. flabellatus they are contiguous); the thorax and elytra differently coloured; the 
legs and palpi in great part testaceous. 
8. Xylophilus sticticus. (Tab. VIII. fig. 2, ¢.) 
Moderately elongate, parallel ; head black; prothorax reddish-brown, the disc stained with piceous; elytra 
brownish-yellow, with an interrupted fascia immediately below the base, a longitudinal extension of 
which runs some distance down the suture, an angulated fascia a little below the middle (connected with 
basal one along the lateral margin and with three longitudinal branches extending upwards on the disc of 
each elytron), and a transverse streak near the suture some distance before the apex, piceous, the shoulders 
and the space in front of the basal fascia brown ; the pubescence long, that on the light parts of the elytra 
ashy. Head large and broad, densely and roughly punctured; eyes (¢') hairy, very coarsely granulated, 
exceedingly large, occupying the whole of the lateral portion of the head (the head very narrowly 
extended behind them), contiguous, very deeply emarginate ; antennse ( ¢ ) reaching to beyond the middle 
of the elytra, hairy, entirely testaceous, joint 3 about three and a half times as long as 2, 4 not half the length 
of 3, 4-10 gradually increasing in length, and each with an exceedingly long and slender ramus, 11 about 
three times as long as 10, much thickened beyond the middle and then abruptly constricted and narrow 
to the apex ; prothorax moderately convex, much narrower than the head, about as long as broad, the 
sides converging from the middle, straight behind, the surface densely and finely punctured; elytra 
moderately long, parallel, very much wider than the prothorax, a little flattened on the disc, and with an 
oblique depression extending from the shoulders downwards towards the suture, the suture also depressed 
at the base, the surface densely and coarsely punctured, the punctures finer at the extreme base; legs 
moderately long, the four anterior femora rather stout, the hind femora strongly incrassate, fusco-testa- 
ceous, the hind femora and tibia much stained with piceous, the anterior tibia with a short tooth on the . 
inner side at the apex. 
Length 3 millim. (¢.) 
Hab. Guatema.a, San Gerénimo (Champion). 
One male example. Closely allied to X. ramosus, but differing from it in its less 
elongate shape, shorter and stouter legs, much broader head, and larger, more coarsely 
granulated, and contiguous eyes. The markings of the elytra and the form and colour 
of the antenne are very similar in both species. The eyes are contiguous in the males 
of X. flabellatus and X. sticticus, distinctly separated in the same sex of X. ramosus. 
4. Xylophilus amule. (Tab. VIII. fig. 3, 2.) 
Moderately elongate, parallel; head black ; prothorax reddish-brown, the disc stained with piceous; elytra 
castaneous, with a small quadrangular patch on either side of the suture below the base, a short oblong 
patch a little below this on the outer portion of the disc, an elongate patch below and in a line with this, 
connected on its inner side with an elongate streak, and a common angulate fascia some distance before 
the apex (not reaching the lateral margin), black, a narrow, angulate, transverse space before and behind 
the anteapical fascia, an oblique space just below the first sublateral spot, and the shoulders (indetermi-
