i9 , 5 Heller: New Philippine Coleoptera 563 
Nearly allied to Colobocles fallax Faust, but besides the different 
color, distinguished by the oblong (in fallax quadrate) scutellum 
and the elytra which show in the intervals, except in the middle 
of the second interval, where there is a row of dense blackish 
bristles, a sparser accumulation of black, remote, seriate, per- 
pendicularly erect (not flat as in fallax) bristles, which form at 
the base of the second and fourth intervals a simple crestlike 
row, instead of a scaled pustule as in fallax Faust. Hind femora 
hardly reaching beyond the third sternite; claw-joint smooth 
as in fallax.
