1872, p. 146, t. 6. 
Type 7. nigricans, L. Koch. Colombia. 
Legs almost entirely without spines. Tibiw, protarsi, and tarsi of legs i. and ii. sometimes cuspulate, sometimes 
plain, beneath. Lower margin of mandibles with from 2-4 teeth. Posterior row of eyes much wider 
than the anterior row, or only slightly wider, recurved. Mazxille long, straight, concave on the outer 
side, dilate at the apex. Median spinners longitudinally compressed. Sternum produced into a square, 
or conical, projection between coxee iii. and iv. 
E. Simon quotes the presence of two teeth only on the lower margin of the mandible 
fang-groove as one of the chief distinguishing characters of the Trachelew as a group 
of the Corinnine. Several of the Central-American species, undoubtedly belonging to 
Trachelas, however, have 3-4 teeth. 
M. Simon has selected 7. minor, O. P.-Cambr., from Jericho, as the type of the 
genus, since Dr. L. Koch evidently acquiesced in the reference of this species to his 
genus T’rachelas. Both were described in the same year. The type of 7. nigricans is 
now before me. 
The species known to me may be tabulated thus :— 
Males. 
A. Maxille evenly rounded on the external apical margin, often dilate, but not 
definitely produced or denticulate. Femur, patella, tibia, and protarsus of 
leg ii. without any anterior marginal row of small tubercles. Lower 
margin of fang-groove with two stout teeth. Basal segment of mandible 
distinctly excavate on the inner margin beneath. 
I. Sternum distinctly granulose or rugulose-impunctate. 
i. Dorsal area of abdomen more or less scutulate. 
a. Tibia of palpus twice as long as broad. (Bulb terminating in a single 
broad, sinuous, lanceolate spur, its apex aculeate.) . 
b. Tibia of palpus not, or only slightly, longer than broad. 
1. Tibia of palpus, in profile from the outside, much broader at the 
apex than at the base, not longer than broad. Apical spur of 
tibia longer, stouter, and slightly curving upwards. Apex of bulb 
with a transverse oblong piece, its anterior outer angle produced 
into a stout spine . 
lanceolatus, sp. n. 
in Sth bs ee ee ee 8 4 transversus, sp. n. 
2. Tibia of palpus, in profile from outside, scarcely broader at the 
apex than at the base, only about one-quarter longer than broad.
