ERYTHRUS ROTUNDICOLLIS, sp. n. (Plate XXIII. fig. 6, ¢.) 
Niger, elytris a bast usque paullo pone medium rufis: antennis 
quam corpore a quarta parte brevioribus, articulis 5° ad \Qv™ 
ad apicem antice dentatis ; prothorace lateraliter rotundato, 
latitudine maximo ad medium, disco tuberculis duobus parvis 
nigro-pilosis vix ante medium positis instructo ; elytris postice 
rotundatim attenuatis, utrisque ad suturam breviter dentatis. 
Long. 17; lat. 4 mm. 
Hab. Mt. Santubong, 2600 ft., February 4, 1900. One male 
specimen. 
Black, with rather more than the basal half of the elytra red. 
Antenne about three-fourths the length of the body, with the 
joints from the fifth to the tenth produced into a tooth at the 
antero-distal angle. Prothorax rather strongly rounded at the 
sides and widest about the middle; the disk with two small 
velvety tubercles placed barely in front of the middle. Elytra 
slightly widening from the base up to about the posterior third 
or fourth, and thence narrowing towards the apex, where each 
ends in a small sutural spme; the disk of each with a rather 
feeble costa extending from the base to a little beyond the middle. 
This species most resembles #. atricollis Pase., but in the latter 
the dark apical area of the elytra is less extensive ; the prothorax 
is less rounded, 1s widest behind the middle, and on the disk has 
but a single median cariniform tubercle. 
ERYTHRUS STERNALIS, sp.n. (Plate XXIII. fig. 7, 3.) 
Niger, elytris a basi usque pone medium rufis : prothoracis disco 
tuberculo mediano inter medium basinque, et utringue tuberculo 
parvo paullo ante basin posito, instructo; elytris postice 
rotundatim attenuatis, utrisque ad suturam sat valde spinosis ; 
prosterno inter coxas tuberculato, mesosterno postice minus 
fortiter tuberculato.

each of the succeeding joints up to the tenth strongly toothed in 
front at the apex. Prothorax strongly and thickly punctured, 
with a median cariniform tubercle between the middle and the 
base, and a small blunt tubercle on each side of the disk nearer to 
the base. Elytra rather strongly punctured; the disk of each 
with a well-marked costa reaching from the base to within about 
tS?
