Mr. J. S. Baly on the Classification of the Eumolpide. 157 
Piomera brachialis, Baly. 
P. elongate, subcylindrical, fulvous, subnitidous, covered witlt pale fulvous 
curved adpressed scales; thorax rugose-punctate ; elytra deeply punc- 
tate-striate, scales on their surface arranged in irregular patches.—Long 
13 lin. 
Hab. Borneo. Collected by Mr. Wallace. 
Head short, triangular, upper portion of face and vertex covered with 
adpressed scales; antennz two-thirds the length of the body, pale 
fulvous, their outer half fuscous. Thorax rather longer than broad, 
cylindrical, narrowed at base and apex, middle portion above thickened. 
Elytra oblong, much broader than the thorax, sides parallel, apex regu- 
larly rounded, surface closely and deeply punctured, the punctures ar- 
ranged in irregular striz, interspaces on the outer disk subcostate. 
Anterior thighs greatly swollen, inner edge of anterior tibiz obliquely 
cut towards their apex. 
Genus Meraxis, Baly. 
Body oblong, subcylindrical, clothed above with regular scales, intermixed 
on the elytra with short rigid erect hairs. Head moderately exserted, 
perpendicular ; antenne slender, filiform, nearly equal to the body in 
length, first joint incrassate, second very short, moderately thickened, 
third slender, equal in length to the two preceding united, the rest each 
nearly equal in length to the third, the four or five terminal joints being 
very slightly shorter and thickened; eyes entire, prominent; epistome 
triangular, wedge-shaped ; mentum angulate-emarginate ; terminal joint 
of maxillary palpi narrow, lanceolate-ovate. Thorax subcylindrical, its 
lateral border obsolete. Hlytra much broader than the thorax, deeply 
punctate-striate, surface covered with regular adpressed scales, mingled 
with which are a few rigid erect hairs. Zegs moderate in length; 
thighs toothed beneath, incrassate, the intermediate pair being much 
less thickened than the first and third, which are nearly equal; inter- 
mediate pair of éébie notched at their apex ; claws bifid. Prosternum 
elongate, broad, somewhat wedge-shaped, its anterior margin con- 
tinuous with that of the epistenum. Mesosternum oblong. 
Type, Metazis sellata, Baly. Borneo. 
This genus is distinguished from Piomera by the form of its epi- 
stome, and also by its mesofemora—these latter, although somewhat 
thickened, being more slender than either the pro- or meta-femora, 
which are nearly equal in size. 
Metaais sellata, Baly. 
M. oblong, subcylindrical, fulvo-fuscous, closely covered with concolorous 
scales, apex of antennz and an oblong patch on the elytra, extending
