POLYPRIA. 97 
The following genera are provisionally referred to the Melandryide. They are in 
some respects intermediate between the Melandryide and the Pythide; but they do 
not agree in several of their characters with either of these families as defined by 
most authors. The coarsely granulated eyes, which are deeply emarginate in front 
in Polypria and entire in the others, and immarginate thorax, the latter narrower than 
the elytra, bring these genera near to some of the heterogeneous forms (Boros &c.) at 
present included in the Pythide, from which they differ in the more or less broadly 
lobed penultimate joint of the tarsi. Hurypus, Kirby, a genus overlooked by Lacor- 
daire, is one of these intermediate forms; and Ischyomius, Chevr., would, as already 
stated, doubtless, be better placed here.

This interesting genus contains a single species, and is apparently peculiar.to Central 
America. Polypriawas referred by its describer to the Othniide, and stated to resemble 
Derestenus, a genus of Cleride. It cannot be included in the Othniide owing to the 
widely open anterior coxal cavities (not mentioned by Chevrolat) and other important 
differences of structure. The genus seems best placed in the Melandryide. The 
anterior coxe are contiguous; the eyes are exceedingly large, deeply emarginate in 
front, and very coarsely granulated; the thorax is immarginate at the sides; the tarsi 
are heteromerous (not five-jointed, as stated by Chevrolat), the outer joints broad and 
lobed beneath, the penultimate one very broadly so, the claws appendiculate; and the 
antenne with joints 4-10 strongly serrate. Polypria is closely allied to Hurypus, 
Kirby, a heteromerous genus doubtfully included in the Cleride by Spinola*; in the 
latter, however, the eyes are not emarginate in front.
