JORDAN—COLEOPTERA: ANTHRIBIDA 249 
the base and a small excision on the distal side of this tooth. The labium is narrow, being 
divided into two slender divergent lobes from the apex halfway down to the insertion of 
the palpi. 
The antennee resemble to some extent those of Sintor and Ischnocerus ; they reach 
about to the centre of the elytra in the $ and to the basal fourth of the same in the ?, 
being clothed with very thin hairs, which form a longer pile on the three segments of the 
club than in the allied genera, the club and the distal segments of the shaft bearing also 
some bristles. Segments 1 and 2 are short and somewhat incrassate, 3—8 long and 
slender, 3 being the longest, 9—11 flat, elongate-ovate, nearly the same in length, 9 rather 
more triangular, 9 and 10 slightly truncate at the apex, 10 and 11 joined to the previous 
segment with a very narrow base. The antennal groove is situated close to and partly 
upon the dilated apical portion of the rostrum, being halfmoon-shaped. 
The frons narrows considerably towards the rostrum, but remains nevertheless very 
broad in both sexes. 
The prothorax is slightly broader than it is long; the anterior carina is slightly 
undulate and extends in an almost even curve to the middle of the sides; the basal 
carina is distinct, but there is no subbasal one, whereas the lateral basal longitudinal 
carina is indicated by a line composed of a few granules, the line forming an acute angle 
with the lateral carina. 
The scutellum is small and semicircular. The elytra are only a very little wider 
than the prothorax, slightly narrowing from the shoulders, being twice as long as they are 
broad together. The pygidium has the apex obtusely pointed and upturned in the 3, and 
subtruncate in the 2. 
The pro- and mesosternal intercoxal processes are narrow. The metasternum bears 
posteriorly a carina at each side of the median line, and the antecoxal sclerite of this 
sternite is completely divided in the centre. 
The legs are nearly the same in. the sexes, excepting the rather greater lengths of the 
d-legs. The tarsi are somewhat over half the lengths of the tibize, the anterior tibia and 
tarsus being the longest. The first segment is longer than the claw-segment in the fore 
tarsus and as long as that segment in the hind tarsus. The second and third tarsal 
segments are rather broader than they are long in both sexes, the lobes of the third being 
rounded-ovate and very conspicuous. The teeth at the inside of the claws are large, flat 
and convergent. 
The ovipositor of the ? is very remarkable for its structure. The two halves are very 
flat and thin (in a dorso-ventral sense) and diverge distally, each tapering to a sharp 
point, the free apical portions being a little longer than the two gonapophyses are broad at 
the point where they commence to diverge and each bearing at the outer edge a tooth 
pointing frontad and the vestige of a second tooth. The eighth abdominal tergite of the 
d (concealed under the pygidium) is deeply cleft. There is only one median vein in the 
hind wing between the cell and the submedian (or anal veins), this median vein not 
reaching to the short hook-like vein emanating from the cell.
