XYLOPHILUS. 183 
Hab. Mexico, Amula in Guerrero 6000 feet (H. H. Smith). 
One male example. This peculiar little species is not very closely allied to any 
other here described; the short and rather broad form, shining surface, comparatively 
small head, small eyes, and peculiar coloration distinguish it easily. The usual oblique 
post-humeral impression on the elytra is scarcely indicated. The hind femora are 
grooved on the inner edge, somewhat as in the same sex of X. fragilis. 
25. Xylophilus unifasciatus. (Tab. VIII. fig. 19, 3.) 
Short and rather broad, opaque, clothed with fine silky appressed pubescence; the head black, the prothorax 
ferruginous, the scutellum piceous, the elytra brownish-testaceous, with a rather narrow, transverse, 
piceous band about the middle, this band extending to the lateral margin and continued along it to the 
base. Head large and broad, densely and very finely punctured, very opaque; eyes (¢) large, slightly 
pubescent, coarsely granulated, occupying the whole of the side of the head, the head not extended behind 
them, widely separated (the intraocular space as broad as the diameter of the eye seen from above), not 
very deeply emarginate ; antenne (3) short, slender, thickening outwardly, testaceous, joint 2 stouter 
and a little shorter than 3, 3 and 4 equal in length, 5-10 gradually increasing in width, 10 about as long 
as broad, 11 twice as long as, and broader than, 10, ovate, acuminate ; prothorax considerably narrower than 
the head, rather convex, nearly as long as broad, the sides straight behind and rounded and converging in 
front, the surface very opaque and punctured like that of the head; elytra broad, widest at the middle, 
feebly transversely depressed below the base, the sides straight in front, the surface finely, densely, and 
shallowly punctured (the punctuation a little coarser than that of the prothorax); beneath, the prothorax 
excepted, piceous; legs (¢) moderately long, testaceous; the femora rather slender, the hind pair 
very little stouter than the others and grooved on the inner edge, the part of the femur on either side of 
this a little extended and piceous in colour; all the tibie slender and almost straight. 
Length 2 millim. (¢.) 
Hab. Muxico, Teapa in Tabasco (H. H. Smith). 
One male example. In this small species the head and thorax are scabrous; the 
former is cut off behind in a line with the hinder portion of the eyes (the head being 
not at all extended behind them), very broad, and opaque; the eyes are large and very 
widely separated; the elytra are not so dull as the head and thorax, and have a 
transverse fascia at the middle extending completely across. In the form of the hind 
femora in the male it approaches X. dzcolor. 
26. Xylophilus inflatus. (Tab. VIII. fig. 20, ¢.) 
Short and broad, convex, finely pubescent ; the head black, opaque; the prothorax fusco-ferruginous, opaque ; 
the scutellum black; the elytra black, with the base broadly, a large oblique spot a little below the middle 
(not quite reaching the suture and distant from the lateral margin), and the apices brownish-testaceous. 
Head large and broad, densely punctured ; eyes( 4) slightly pubescent, rather coarsely granulated, large, 
occupying the whole of the side of the head (the head not at all extended behind them), very widely 
separated (the intraocular space considerably broader than the diameter of the eye seen from above), 
somewhat feebly emarginate; antenne (¢ ) short, slender, widening a little outwardly, testaceous, joint 2 
very little shorter than 3, 3 and 4 subequal, 5-10 very gradually increasing in width, 9 as broad as long, 
10 transverse, 11 about twice as long as, anda little stouter than, 10, ovate ; prothorax at the base scarcely 
narrower than the head, broader than long, rather convex, the sides converging almost from the base, 
the surface densely and finely punctured ; elytra about one half broader than the prothorax, comparatively 
short and broad, widest about the middle, the sides a little rounded, the surface very closely and finely
