432 Mr. Blandford on the Scolyto-platypini, 
Antenne short in both sexes, scape strongly clubbed in the 
males, funiculus short but variable in structure, in one form being 
in direct line with the scape, with the first joint clubbed as in the 
females, in the other being flexible, with the first joint produced 
internally so as to be transversely subcylindrical; club oval, acumi- 
nate, ciliated on its inner border and apex with a fringe of long 
hairs. In the females the antenna is of the type already described, 
with the first joint of the funiculus clubbed; the club is oval, and 
acuminate in the form where the male funiculus is flexible. 
Anterior border of the basilar piece of the head straight in the 
males, the mental peduncle narrow, transverse, with a median 
process for its attachment to the head; in the females the mentum 
is about 24 times longer than broad, narrow at base, and dilated 
towards apex, with the sides slightly concave. Prothorax sub- 
quadrate, base slightly bisinuate, not produced in middle, the 
posterior angles sharp, but not produced, lateral emarginations 
shallow, their anterior angles indistinct, so that the sides appear 
sinuate. LElytra cylindrical, scarcely visibly striate or non-striate, 
except at apical declivity, where the striz are distinct; interstices 
of declivity finely tuberculate in the male, or carinate at base. 
The anterior legs are somewhat slender in the males, and the 
inferior junction of trochanter and femur is not angulate; very 
robust in the females, with the inferior junction forming a distinct 
angle. 'Tarsi distinctly shorter than tibie, with 2nd and 38rd joints 
vertically flattened and triangular, 1st less distinctly so; 1st joint 
of middle and posterior pairs shorter than 2nd.

antice fusco-nigro vel omnino infuscato, elytris ferrugineis, striga 
media plus minusve infuscata, vel nigris, antennis pedibusque fer- 
rugineis; prothorace transyerso, lateribus sinuatis, antice rotundatis, 
subtilissime reticulato, punctato; elytris subtiliter striatis, inter- 
stitiis multi-punctatis; declivitate striis nonnihil profundioribus, 
interstitiis rugosis, mo et 3io tuberculatis. Long. 8°5—4 mm.
