metasternum and the epipleura strongly and closely 
vermiculate-striate. Each abdominal segment has at 
the sides a band of strong hair-bearing punctures. 
Hab. Colombia. 
B. Claws of the anterior tarsi not bifid, but with a 
small tooth at the base; the larger claw of the four 
posterior tarsi bifid. 
6. Thyridium punctatissimun, 0. 8. 
Obovatum, viridi-olivaceum ; elytris creberrime punc- 
tatis, pygidio corporeque subtus olivaceis, fulvo-hirtis, 
pedibus cyaneo-olivaceis, tarsis cyaneis. Long. 12 lin. 
Antenne and parts of the mouth bluish black. Head 
in parts finely punctured, the front margin of the clypeus 
rugulose. Thorax 7$ millimetres long, 12 millimetres 
broad across the middle, rounded anteriorly at the sides, 
gently sinuate behind the middle; sparingly and deli- 
cately punctured, except at the base, where the punc- 
tures become more frequent; the surface within the 
margin is closely (and almost rugulosely) punctured, but 
not at the hind angles; the incrassated margin is darker 
olive than the rest of the thorax ; the basal lobe is broad 
and not very prominent, and gently arcuate, with scarcely 
any sinuosity on each side of it. Scutellum a curvi- 
linear triangle, 4 millimetres broad, 33 millimetres long. 
Elytra very thickly punctured, with a mixture of larger 
and small punctures; there is a distinct sutural stria 
(the suture nearly smooth), and there are two pairs of 
impressed lines on each elytron ; the margin below the 
shoulder is slightly incrassate. Pygidium moderately 
strongly vermiculate-striolate. Sternal process rather 
strong, moderately inflated and obtusely rounded at the 
apex. Sides of the metasternum and epipleura densely 
vermiculate-striolate, the areas thus formed very small, 
and each having in the centre a small puncture. Sides 
of the abdomen rather strongly punctured. _
