SOME MEXICAN PHALANGIDA. 
By Nathan Banks. 
Cynorta mexicana, sp. nov. 
Length body, 6.5 mm.; breadth, 4.5 mm. ; femur I, 2 mm.; femur II, 3.5 mm. 
Dull yellow brown, tibiae darker, last palpal joint black. Dorsum nearly smooth', 
eye tubercle low, smooth; tibia of palpus very broadcast joint ending in a fine 
curved claw; legs I, II and III nearly smooth, with fine hairs; venter smooth; 
dorsum of abdomen with low tubercles along each side to the hind femora, on hind 
part of middle a pair of very small tubercles, scarcely evident, and behind them a 
transverse row of four minute tubercles, the hind border of the shield and of the 
next two segments with a row of small tubercles; hind leg spinulate on femur, patella 
and tibia, rather more strongly on last two, on inner side of femur near tip is a larger, 
prominent, blunt spine. Readily known from our forms by larger size, absence of 
markings, small tubercles, and armature of hind leg. 
Erginus mexicana, sp. nov. 
Length, 3.9 mm.; femur I, 1.7 mm.; femur II, 3.1 mm. Body almost uniform 
pale yellowish, legs paler, nearly white. Dorsal surface evenly and rather roughly 
granulate, eye-tubercle broad, low;'basal joint of mandibles swollen above mid 
prominent, distinctly granulate; palpi appressed to mandibles, the femur broad, den¬ 
ticulate above, below on inner margin with six blunt teeth, tibia very broad, concave 
within, margins with bristles, tarsus slender, one half length of the tibia, ending in a 
long, fine, curved claw; venter and coxae granulate; the margins of the very much 
retracted segments denticulate; legs slender, finely granulate, fourth pair nearly as 
long as second, but the fourth tarsus shorter than that of second leg. 
One specimen; readily known by the blunt teeth under the femur 
of palpus. 
Liobunum mexicanum, sp. nov. 
Length body 4 mm., femur I, 11 mm., femur II, 18 mm. Dark brown above, 
■nearly uniform, but faintly showing a chocolate brown vase-mark on basal part of 
■abdomen; beneath wholly pale; palpi pale, brownish on base of the femora, above 
•on patellae, and at base and tip of the tibiae; mandibles pale ; legs brown, with scat¬ 
tered pale dots on basal joints, often arranged in groups, coxae pale, trochanters brown¬ 
ish, extreme tip of tibiae pale. Dorsum above quite finely and regularly granulate; 
«ye-tubercle quite high, smooth, the eyes prominent; last joint of palpus as long as 
tibia and patella together, scarcely curved, each of the coxae I, II and III terminate 
above next to the body in a small white spine. 
Amecameca [Barrett]. The specimen has but three legs on the right 
side, leg II being absent and its coxa is rudimentary. 
Liobunum albipalpe, sp. nov. 
Length body 5 mm., femur I, 12 mm., femur II, 20 mm. Palpi white, basal 
joints rather yellowish, mandibles pale yellowish; cephalothorax black in center,
