Group HEBESTOLINI. 
This group corresponds with Lacordaire’s “Groupe” Hébestolides. It forms the 
connecting link between such genera as Hstola among the Pogonocherini and the 
Phyteeciini, having the toothed tarsal claws of the latter and all the other characters 
and facies of the former. According to Lacordaire, the Hebestolini are distinguished 
from the other groups having toothed tarsal claws by the closure of their intermediate 
acetabula. ‘This is a character of extremely doubtful application ; and the difference 
in the form of the acetabula between Ewmathes of this group and Drycothea of 
the group Calliine is so slight that, the great resemblance between the species of the 
two being considered, it seems in the highest degree artificial to place the two genera 
- In separate groups. 
EUMATHES. 
Eumathes, Pascoe, Journal of Entom. i. p. 354; Bates, Ann. & Mag. Nat. Hist. ser. 3, xvii. p. 296 ; 
Lacordaire, Gen. Col. ix. p. 914. 
Four species of this genus have been described, all 'Tropical-American. 
1. Eumathes cuprascens. (Tab. XV. fig. 17.) 
Eumathes cuprascens, Bates, Trans. Ent. Soc. 1873, p. 238. 
Hab. Nicaracva, Chontales (Belt). 
The middle acetabula are slightly more open externally than in Humathes undatus, 
and, in fact, are of the same form as in Drycothea salle. ‘This species ought therefore, 
according to Lacordaire’s views, to be removed from the Hebestolini to the Calliini 
group. But, on the other hand, the middle tibize are notched and grooved, and the 
mesosternum convex and keeled, as in Eumathes. 
CYMATONYCHA. 
Cymatonycha, Bates, Trans. Ent. Soc. 1873, p. 234. 
The following is the only known species. The tarsal claws in this genus have only a 
rudiment of dentiform projection at their base.
