210 HETEROMERA. 
9. Notoxus crucifer. (Tab. IX. figg. 18, 18a, 2.) 
Moderately elongate, subparallel, piceous, shining, somewhat thickly clothed with fine decumbent hairs ; the 
prothorax with the extreme base and the horn reddish-testaceous; the elytra each with an oblique stripe 
extending from the shoulders nearly.to the middle, and a transverse band considerably beyond the middle, 
neither of which reaches the suture (the transverse band widening inwardly, obliquely cut off on its inner 
side, and extending to the lateral margin, the oblique stripe widening posteriorly and extending along the 
base), testaceous. Head finely and rather closely punctured, finely pubescent, with a few short erect hairs 
in front, the front concave ; prothorax rather broader than long, finely and somewhat closely punctured— 
the horn ( 2) long and parallel, moderately broad, feebly margined, the sides finely but distinctly serrate, 
the tip oval, the crest raised, subparallel, the sides finely margined and crenulate; elytra moderately long, 
subparallel, finely and closely punctured, the punctuation finer towards the apex, the usual oblique depres- 
sion below the shoulders shallow, the humeri distinct, the apices ( 2 ) conjointly rounded ; beneath entirely 
piceous; antenna ferruginous; legs reddish-testaceous, the femora darker. 
Length 3 millim. (92.) 
Hab. Guatemaa, San Gerénimo (Champion). 
One rather worn female example. Closely allied to V. fraternus, from which it differs 
in the thoracic horn being distinctly serrate at the sides and considerably longer (though 
of similar width), and the crest more parallel. The apices of the elytra are conjointly 
rounded, and very differently formed from those of the opposite sex of VV. fraternus or 
of the same sex of WV. truncatipennis. The elytral markings, as in the two last-mentioned 
species, are, no doubt, subject to considerable variation; the pubescence appears to 
partake of the colour of the surface, though it is whitish at the sides before the middle. 
10. Notoxus acuminatus. (Tab. IX. figg. 19, 194, 3.) 
Elongate, narrow, piceous, thickly clothed with fine decumbent pubescence and with scattered, serially arranged, 
long, erect hairs intermixed; the prothorax with the horn, and sometimes the sides and base, rufous; the 
elytra variable in colour—usually with an oblique stripe extending from the shoulders downwards (not 
reaching the middle, but continued along the base to the scutellum), an angulated fascia of variable 
width beyond the middle (separated from the oblique stripe by an angulated, broad, median fascia of the 
ground-colour), and the extreme apex (except in one specimen) testaceous, in one example testaceous with 
a large piceous median patch (not reaching the suture, but laterally extending upwards to the shoulders) 
and the scutellar and ante-apical regions infuscate. Head dull, finely and rather thickly punctured, the 
front concave ; prothorax as long as broad, oval, densely and finely punctured, opaque—the horn long, rather 
broad, a little narrower in the male, rounded at the tip, the sides serrate and rather feebly margined, the 
crest about half the width of the horn in both sexes, moderately raised, its margin indicated by a row of 
small tubercles ; elytra narrowing from the middle to the base, elongate-oval, closely and very finely 
punctured, the punctures still finer towards the apex, the usual oblique depression below the shoulders 
deep in both sexes, the humeri distinct, the apices produced and the sutural angles rather sharp in both 
sexes; beneath piceous; antenne and legs testaceous, the intermediate joints of the former and the 
femora and tibie often infuscate; fifth ventral segment broadly transversely concave and the apex trun- 
cate in the male. 
Length 23-3; millim. (¢ 2.) 
Hab. GuateMaua, Quezaltenango 7800 feet (Champion). 
Four male and two female examples. ‘This small narrow species differs from the 
allied forms in the subacuminate apices of the elytra in both sexes. The elytra are 
distinctly narrowed towards the base; the markings are variable, according to the
