cavities closed externally; prosternal episterna without well-defined suture in front, and not separated 
from the prosternum ; middle coxe separated by the mesosternum, the latter long and slightly keeled 
in front, the mesosternal epimera very sharply defined and extending to the cavities and closing them 
externally ; metasternum long; legs very long, the four hinder tarsi exceedingly elongate, the four hinder 
tibie with a series of coarse transverse ridges on their outer edge, the first joint of the posterior tarsi 
equal in length to the second and third joints united; front, middle, and hind tibie with spurs of unequal 
length (those of the hind pair only a little longer than those of the middle pair), one very long, the 
other considerably shorter, both strongly pectinate beneath ; anterior tarsi broadly dilated in the male, the 
penultimate joint of the anterior and intermediate pairs feebly lobed beneath (that of the anterior pair 
strongly so in the male), the corresponding joint of the hind pair simple; claws slender, slightly 
dilated at the base; body very elongate, narrow, and cuneiform, strongly compressed laterally beneath. 
This interesting new genus contains a single widely distributed species, which ranges 
from Mexico to the Amazons. In the structure of the maxillary palpi, Cuphosis very 
nearly agrees with Serropalpus, Dentipalpus, and Ctenoplectron, but differs from each of 
these in several important structural characters; in the pectinate tibial spurs it 
approaches Orchesia. Cuphosis may be at once identified from all these allied genera 
by its very elongate cuneiform shape, long and slender limbs, unequal and pectinate 
tibial spurs, and strongly transversely ridged tibie. ‘The inner lobe of the maxille 
is very narrow, much narrower than in Serropalpus. Closely allied forms inhabit 
Australia. ‘Though so widely distributed, the insect appears to be everywhere very rare.

_ Piceous- or ferruginous-brown, subopaque, densely clothed above and beneath with very fine, ashy, appressed, 
silky pubescence. Head very finely and closely punctured; antenne reaching to about the middle of the 
elytra, fusco-testaceous; prothorax a little rounded at the sides, slightly narrowed in front, the hind 
angles cbtusely rectangular, the sides finely margined from the base to a little before the middle, the disc 
usually canaliculate and with a large and very shallow impression on each side a little behind the middle, the 
surface very finely, densely, and uniformly punctured, the pubescence usually of a browner or more fulvous 
colour in places, in some examples of a unicolorous ashy tint; elytra with a sharp sutural stria and very 
shallow longitudinal grooves, in some examples with a longitudinal series of broad shallow transverse depres- 
sions across the disc, the surface very finely and densely punctured, the punctuation becoming a little coarser 
and more crowded at the base, on the shoulders assuming the form of transverse rugs, and more scattered 
towards the apex, the apices narrow and rounded; beneath very finely, densely, and uniformly punctured ; 
legs fusco-testaceous.
