nately) brownish-yellow ; the pubescence long and variegate. Head moderately large, ensely and roughly 
punctured ; eyes (2) clothed with short, erect, pubescence, coarsely granulated, large, occupying almost 
the whole of the side of the head (the head very narrowly extended on either side behind them), rather 
narrowly separated, very deeply emarginate; antenne ( @ ) testaceous, slightly infuscate at the base, about 
reaching to the basal third of the elytra, moderately stout, thickening a little outwardly, joint 2 short and 
globose, 3 more slender than, and nearly twice as long as, 2, 4—10 decreasing gradually in length, 9 and 
10 as broad as long, 11 about twice as long as, and very much stouter than, 10, abruptly and obliquely 
constricted beyond the middle, and with the apical portion slender; prothorax about as long as broad, 
not very convex, narrower than the head, the sides obliquely converging from the middle, straight behind, 
the surface densely and finely punctured ; elytra moderately long, parallel, rather broad, a little flattened 
on the disc, and with a rather deep oblique depression extending from the shoulders downwards towards 
the suture, the suture also depressed at the base, the surface slightly shining, densely and coarsely punc- 
tured ; legs (2 ) moderately long, the hind femora incrassate, reddish-testaceous, the basal half of all the 
tibize and the hind femora beyond the middle piceous, the tarsi flavo-testaceous.

Hab. Mexico, Amula in Guerrero 6000 feet (1. H. Smith). 
One female example. This elegant insect, the male of which doubtless has flabellate 
antennee, is perhaps nearest allied to X. ramosus. ‘The less coarsely granulated eyes 
distinguish it from X. flabellatus and X. sticticus; the legs are formed as in the latter, 
but are less elongate than in the former. The pattern of the elytra is quite different 
from that of these three species, and the insect cannot possibly be the other sex of one 
of them. 
5. Xylophilus trifasciatus. (Tab. VIII. tig. 4, 2.) 
Rather short, parallel ; head black ; prothorax piceous, with the base and apex narrowly reddish-brown, or 
reddish-brown and more or less suffused with piceous; elytra brownish-testaceous, with two angulated 
fascize, one near the base and another below the middle, connected along the suture and at the sides,. 
and a narrower subangulated fascia some distance before the apex, black or piceous—in some exam- 
ples the fascize are broken up into spots, and do not reach the suture, in others the piceous colour is more’ 
extended ; the pubescence long, that on the elytral fasci# ashy. Head large, densely and roughly punc- 
tured; eyes hairy—in the male exceedingly large, occupying the whole of the lateral portion of the 
head (the head very narrowly extended behind them), very coarsely granulated, deeply emarginate 
—in the female smaller, separated by a space about equalling half the diameter of the eyes as seen 
from above, rather more finely granulated, and less deeply emarginate (the head a little more broadly 
extended on either side behind them); antennz hairy—( ¢) reaching to beyond the middle of the elytra, 
rather slender, joint 2 short and globose, 3 about three times as long as 2, 4 not half the length of 3, 
4-10 very distinctly increasing in length, and each with an exceedingly long and slender ramus, 11 
nearly three times as long as 10, much thickened beyond the middle, and then abruptly constricted and 
slender to the apex, 1 and 2, the rami in great part (the tip only of the lower one), and 11 (except at the 
base) piceous, the rest testaceous—( 9 )- reaching to about the basal fourth of the elytra, stouter, 
widening outwardly, joint 3 about twice as long as 2, 4 shorter than 3, 4—8 almost equal in length, 9 and 
- 10 a little shorter, 11 twice as long as, and much stouter than, 10, very obliquely truncate at the apex, the 
apex pointed, 1 and 2 and 10 and 11 piceous or infuscate, the rest testaceous ; prothorax about as long 
as broad, not very convex, narrower than the head, the sides converging from the middle, straight behind, 
the surface densely and finely punctured ; elytra short, parallel, rather convex, with a shallow oblique 
depression extending from the shoulders downwards, the suture also depressed at the base, the surface 
densely and coarsely punctured ; legs moderately long, reddish- or fusco-testaceous, the four anterior 
femora darker outwardly, the hind femora and hind tibie more or less piceous, all the tarsi flavo-testa- 
ceous ; the hind femora strongly incrassate in the male, moderately so in the female. 
Length 2-24 millim. (d 2.)
