JORDAN—COLEOPTERA: ANTHRIBIDA 263 
The prothorax and elytra are almost perfectly cylindrical. The former is slightly 
wider than long and rounded-angustate from the middle to the apex, the whole upper 
surface very densely reticulate-punctate; the carina is dorsally almost straight, being 
very faintly incurved thrice, its lateral angle is obtuse, but not rounded off, and the 
lateral carina does not extend to the centre of the sides. 
The elytra are not broader than the prothorax, but more than half as long again. 
They are clothed, like the pronotum, with a very sparse pubescence which is only 
visible under a strong lens, and regularly punctate-striate, the punctures being large ; 
the base of the sutural interspace is much widened and bears a short stripe of punctures. 
The anterior luteous patch expands between stripes 2 and 8 and reaches the basal 
margin between 4 and 8, whereas the subapical patch expands between stripes 1 and 8, 
the suture being here pitchy. 
The prosternum is as convex as the pronotum and has the same surface-structure.

Long. (cap. excl) 2—2°5 mm. 
One ¢# and one 3. 
The present insect is clothed with short stiff appressed hairs, which, however, do 
not conceal the derm anywhere and are not condensed into markings. The head is 
coarsely rugate-punctate. The pronotum is minutely coriaceous and very densely 
covered with shallow punctiform pits which form a net; it is a little broader than 
it is long, with the sides rotundate in the centre, narrowed towards the apex and 
faintly incurved in front of the carina; the disc is slightly depressed before the carina. 
The angle of the carina is rounded, and the lateral carina does not reach to the 
middle of the sides. The elytra are more strongly convex than the pronotum, and 
almost twice as long, being broadest before the centre and thence to apex nearly 
evenly rotundate-angustate. The punctures of the stripes are very large and deep. 
The pygidium bears a smooth groove at the base, as a continuation of the central 
groove of the propygidium. The sterna are studded with large deep punctures and 
the abdominal segments bear a row of similar punctures at their bases. The tarsal 
segments 2 and 3 are narrower than in any species of Scortetinus. 
A second specimen, a f with the antennz missing except for the basal segments, 
doubtless belongs to this species. It is larger than the 3, being 2°5 mm. long. The 
pygidium, which is granulose in the ?, is more rugose in the §. The abdomen of 
this ¢ is medianly flattened and the last sternite distinctly swollen at each side. 
The underwings are large in both specimens. The anal area is narrower than 
the apex of the cell; there is a small basal anal lobe separated from the anal area
