i9, 5 Heller: New Philippine Coleoptera 531 
lindrico, palpi labiales articulo ultimo perlongo, cylindrico, 
acuminate. Oculi transversi, reniformes. Prothorax latitudine 
baud longior, globosus, basi fortiter constrictus. Tibiae anticae 
rectae, posticae tumidae. Unguiculi in dimidia parte basali 
dentato-dilatati. 
Diplophorus Fairm. has similar, but much shorter bipectinate 
antennse; nothwithstanding this the new genus is more closely 
allied to Cladiscus. It is distinguished from Cladiscus by the long 
bipectinate antennae, as well as by the very long apical joint of 
labial palpi, which is six times longer than thick; the medially 
subtransversely spheric thorax; the thickened hind tibiae; and 
the broadly dentate unguiculi. 
Biplopherusa tumidipes sp. nov. Plate 1, fig. 6. 
Nigro-cyanea, antennis atris, articulis 3 ad 10 subter longe 
biramosis, elytris palpisque testaceis ; prothorace margine basali 
sanguineo, creberrime punctate, margine antico leviusculo, parte 
basali constricto transverse subrugoso; elytris crebre seriato- 
punctatis, in dimidia parte, minore, apicali, dense punctulatis; 
tibiis posticis fortiter clavatis. 
Long. 11 mm., lat. 2.2. 
Luzon, Mount Banahao. 
Body dark steel blue, thorax coarsely and densely punctate, 
in the apical part with fine and scattered punctures, on the 
contracted basal part transversely wrinkled, the basal margin 
dark red ; elytra pale cinnamon in color, in the basal two-thirds 
coarsely and subtransversely seriate-punctate, on the posterior 
third with irregular fine and dense punctures ; hind tibise 
strongly clavate. 
Cladiscus bacillus sp. nov. Plate 1, fig. 7. 
C. strangulate affinis, niger capite prothoraceque parte ante- 
riore subrufescentibus, hoc parte basali longiore; antennis ser- 
ratis, articulis duobus basalibus testaceis; prothorace fortius 
punctato; elytris latitudine basali 4.5 partibus longioribus, striis 
punctatis omnibus spatiis latioribus. 
Long. 6.5 mm., lat. 0.7. 
Luzon, Mountain Province, Baguio. 
A unicolored black, cylindric species similar to C. strangulatus, 
but with serrate antennae, the two basal joints fulvous, joints 
8 to 10 hardly longer than broad, the last elliptic, not quite twice 
as long as thick; front between eyes distinctly convex, moder- 
ately densely but rather strongly punctate; constricted basal 
part of prothorax less transverse, trapeziform, strongly strigose
