of the legs and under surface, the two examples agree almost exactly with each other. 
The species is not very closely allied to any other here enumerated. 
11. Oxacis pictipennis, (Tab. VII. fig. 13.) 
Elongate, narrow, thickly and finely pubescent; the head and prothorax shining, flavo-testaceous ; the elytra 
very opaque, luteous, each with a brownish-black spot at the middle of the base and a similarly-coloured 
longitudinal streak on the lateral margin just below the shoulder (not visible from above) and another on 
the middle of the disc. Head broad, finely and sparsely punctured, a longitudinal space in the middle 
between the eyes and the epistoma smooth, the tips of the mandibles, the last two joints of the maxillary 
palpi, and the eyes black; antenna rather slender, extending to beyond the middle of the elytra, piceous, 
the basal joint fusco-testaceous, the third joint shorter than the first, the eleventh constricted at the 
middle; prothorax much longer than broad, the sides strongly rounded anteriorly, abruptly constricted at 
the middle, and thence to the base parallel, the disc feebly canaliculate in the middle behind, the surface finely 
and thickly punctured; elytra subparallel, densely and minutely punctured, and with two fine raised 
lines on the disc; beneath densely and finely punctured, entirely testaceous ; legs testaceous, the tibia 
and tarsi piceous. 
Length 84 millim. 
Hab. Guatemata, Teleman (Champion). 
One specimen, apparently a male, captured by myself in the lower part of the 
Polochic Valley. The peculiar coloration and other particulars mentioned above 
distinguish this species at once from all the allied forms. 
12. Oxacis bilineata. (Tab. VII. fig. 14, 2.) 
Elongate, thickly pubescent; the head and prothorax shining, pale flavo-testaceous; the elytra opaque, 
stramineous, each with a very narrow blackish-brown stripe along the lateral margin, extending from 
just below the shoulder nearly to the middle and not visible from above, and a similarly-coloured very 
narrow stripe on the disc, the latter extending three-fourths of the elytral length. Head finely and 
sparsely punctured at the sides and behind, smooth along the middle and in front, the eyes and the tips of 
the mandibles black, the apical joint of the maxillary palpi infuscate at the base; antenna ( 3) very long, 
extending far beyond the middle of the elytra, slender, testaceous, joints 2-4 a little darker, 3 shorter 
than 1, 11 constricted at the middle; prothorax much longer than broad, narrow, the sides moderately 
rounded anteriorly, constricted at the middle, and thence to the base almost parallel, the dise shallowly 
depressed in the middle behind and with a smooth median line, the surface closely and finely punctured ; 
elytra subparallel, closely and minutely punctured and with one fine raised line on the disc (the usual 
second line obsolete) ; beneath densely and finely punctured, pallid testaceous, the metasternum a little 
darker ; legs slender, pallid testaceous, the tibiee and tarsi piceous-brown. 
Length 74 millim. (¢.) 
Hab. Panama, Bugaba (Champion). 
One example. This species is closely allied to O. pictipennis, from which its narrower 
head and thorax (the latter much less rounded at the sides anteriorly), more slender 
limbs, and different elytral markings sufficiently distinguish it. The apical joint of the 
maxillary palpi, as in O. pictipennis, is long and cultriform. The narrow lateral stripe 
of the elytra is completely invisible from above. 
13. Oxacis pilosa. (Tab. VII. fig. 15.) 
Elongate, slightly shining, testaceous or fusco-testaceous, thickly clothed with long coarse decumbent hairs, 
-Head coarsely and closely punctured, the tips of the mandibles piceous, the eyes scarcely darker ; antenne
