GRAPTOCLEPTES.—ATRACHELUS. 283 
Temax in N. Yucatan (Gaumer); GuaTeMaLa, San Juan in Vera Paz (Champion); 
Panama, Bugaba (Champion). 
We possess eleven specimens of this species and four others belonging to the Vienna 
Museum have been seen, including one of the (2) types. It varies a good deal in size, 
and some examples have a large sanguineous patch on the disc of the posterior lobe of 
the pronotum. The femora usually have each a narrow pale median annulus, but this 
is sometimes present on the hind pair only. The males (unknown to Stal) have large 
and prominent eyes, the third joint of the antenne thickened to beyond the middle, 
and the terminal genital segment somewhat broadly produced in the centre at the 
apex. 
AMAUROSPHODRUES. . 
Amaurosphodrus, Stal, Ofv. Vet.-Ak. Férh. xxiii. p. 295 (1866) ; Enum. Hemipt. ii. pp. 69, 82. 
A Tropical-American genus, including two species, one of which extends to the State 
of Panama. — 
1. Amaurosphodrus alboannulatus. (Tab. XVII. figg. 15, 15a, 2.) 
Zelus alboannulatus, Stal, Ofv. Vet.-Ak. Forh. 1855, p. 189’.

Hab. Panama, Bugaba, Tolé (Champion).—CotomBia, Los Remedios ! 3, Bogota. 
Seven examples, all females, like the type. This species is very like Graptocleptes 
sanguineiventris, but has stouter and more hairy legs, the posterior tibia are unequally 
incrassate, and the head is armed with two moderately long spines, the post-ocular 
portion being thickly pilose above and beneath. It is shining black, with the basal 
half of the venter bright sanguineous ; the femora have each a narrow pale annulus at 
the middle. 
ATRACHELUS. 
Atrachelus, Amyot et Serville, Hist. Nat. Ins. Hémipt. p. 374 (1848); Stal, Ofv. Vet.-Ak. Foérh. 
XXill. p. 293 (1866); Enum. Hemipt. ii. pp. 68, 78. 
The two described species of this genus are from the Southern United States and 
the Argentine Republic respectively ; the first mentioned extends southwards to Mexico 
and Guatemala. A third is now added from Panama. Atrachelus is very imperfectly 
characterized by Amyot and Serville, and their figure is a bad one. The genus is easily 
separable from Acholla and Sinea by the unarmed anterior femora. Phorobura, Stal, 
including three species from Tropical South America, seems only to differ from 
Atrachelus in having the post-ocular portion of the head relatively longer.
