DIPLOPODA. 
ONISCOMORPHA. 
Glomeridz. 
ZYGETHOMERIS, gen. nov. 
Resembling Rhopalomeris, Verhoeff, based upon Wood’s 
species bicolor from the Malayan peninsula, in the peculiar 
sixth article of the antenna, which is greatly enlarged, 
somewhat curved, and obviously compressed from side to 
side. Unlike Rhopalomeris, however, the seventh article is 
less flattened and obliquely extended against the sixth, 
being clearly set off and possessing only four well- 
separated sensory cones instead of numerous ones. The 
body is strongly pigmented. 
Genotype, Z. lamprus, sp. n. 
Zygethomeris lamprus, sp. 0. 
Differing from Glomeris concolor, Pocock, also from 
Borneo, strikingly in coloration. In the present species the 
dorsum is deep chocolate-brown, with the keels and caudal 
borders flavous. Head flavous below, also in a narrow 
transverse stripe across vertex, below which is an A-shaped 
pattern extending to the antenne. Venter and legs fulvous. 
Head with transverse ridge above well marked. Antenne 
short ; the sixth article much longest and stoutest, clavately 
widening distad with dorsal surface concave and ventral 
convex, strongly flattened from side to side; third article 
second in length; seventh article short, attached by an 
oblique base, with four (or on one side five) sensory 
cones. Ocelli on each side seven in a single row. 
Collum crossed in front by two distinct transverse sulci. 
Second tergite behind front margin with nine or ten much 
finer transverse sulci on each side, most of these con- 
tinuing also across the mid-dorsal region. 
The anal tergite of the male as viewed from above 
is convex from side to side ; in caudal view the edge is 
nearly horizontal, being only very slightly obtusely emar- 
ginate or indented after the middle. 
In the male the seventeenth and eighteenth pairs of legs 
are much reduced, the eighteenth exceeding the seventeenth, 
though not greatly so; first joint on mesal side with an 
acute vertical process, and on outer side giving rise to a thin 
plate, against the anterior face of which the leg lies. The
