a new subfamily of Scolytide. 431 
angulately flexed, so that the anal opening is dorsal and not 
terminal. Anterior coxe remote, large, quadrate and flattened, 
in the females produced externally into a short lobe over base of 
femora; trochanters applied to whole base of femora, which are 
short, stout and compressed, with the lower internal border lobed 
at apex; the lobe small in the male, very large in the female, and 
covering the base of the tibia, so that the femora appear as broad 
as long when seen on their inner aspect. Anterior tibiz curved, 
dilated gradually in male, strongly in female, their outer border 
spined to near apex, then strongly excavate, the excavation limited 
below by an outwardly directed spine; in the female scabrous 
externally with transverse rows of coarse tuberculation, which are 
nearly obsolete in the male. Middle cox rounded, remote, pos- 
terior, transverse, pointed, nearly contiguous ; middle and posterior 
femora oblong, tibie curved, slightly dilated, flattened and 
grooved for tarsi, with the outer edge crenate with fine teeth. Tarsi 
not longer than tibie ; first joint at most less than twice as long as 
second, which is equal to or slightly shorter than third, fourth 
very small, hardly discernible, fifth elongate; all joints simple, 
the first three with slight vertical flattening.
