GONIADERA. 229 
Group GONIADERIDES. 
This group is represented in Central America by two genera only; the South- 
American Phymatestes (Phymatodes, Blanch.), Gamazxus, and Amymone contain as 
yet no representative in our country. Xanthicles is noteworthy on account of the 
completely divided eyes and Caraboid facies. The “Goniaderides” are connected 
with the ‘ Heterotarsides ” by several more or less intermediate forms. The group is 
almost confined to the tropical regions of the New World, though one genus, Mdia- 
torix, has been described from Java. 
GONIADERA. 
Goniadera, Perty, Del. anim. art. Brasil. p. 62 (1830); Blanchard, Hist. Nat. Ins. 11. p. 35 (1845) ; 
Lacordaire, Gen. Col. v. p. 391; F. Bates, Trans. Ent. Soc. London, 1868, p. 315, nota. 
Goniodera, Castelnau, Hist. Nat. Ins. Col. ii. p. 238 (1850) ; Gemm. & Har. Cat. vii. p. 1988. 
This genus contains numerous Tropical-American species, fully half of which are 
undescribed as yet; six species inhabit Central America. The nondescript species from 
Java mentioned by Lacordaire (op. cit. p. 392, nota) is probably an Adiatoriz. Most 
of the Goniadere captured by myself were found by beating the withered still-attached 
leaves of fallen forest-trees or beneath loose bark.

A wide-ranging species. The large number of specimens before me vary considerably 
in the shape and sculpture of the thorax, and also in the sculpture of the elytra, but I 
think they can only be regarded as representing one variable species. G. impressa, 
Er., from Peru, would appear to be closely allied to G. repanda, but has the thorax 
more acutely angled at the sides before the middle, and with three impressions before 
the base, the elytra costate, &c.
