Tunabo,! gen. nov. 
Cephalothorax longer than broad, moderately convex, the posterior 
declivity abrupt; thoracic stria long. 
The anterior row of eyes weakly procurved; median eyes farther 
from each other than from the laterals, a little larger than the laterals. 
Posterior eyes in two distinct rows as in Lycosa, much larger than 
those of the anterior row. Area of median eyes decidedly wider than 
long and much wider behind than in front. Clypeus much narrower 
than area of median eyes, only a little exceeding the diameter of an 
anterior median eye; subvertical. 
Labium wider than long. 
Lower margin of furrow of chelicera with four teeth. 
All tarsi, and the anterior metatarsi at least in part, scopulate. 
Anterior tibiae armed beneath with five pairs of spines, the distal 
pair small and the others very long; the met&tarsi armed beneath 
with three pairs of spines. 
Genotype.— Tunabo peruvianus sp. nov. 
Easily distinguished from Trechalea, the preceding genus, in having 
the anterior eyes in a procurved row, and from Hygropoda, also 
occurring in the Andean region and a closely related genus, in the 
relatively much larger posterior eyes, in the much narrower clypeus, 
and in having leg IV longer than leg I. 
TUNABO PERUVIANUS, sp. nov. 
Plate 22, fig. 7-9. 
A sharply defined median longitudinal stripe over entire length of 
carapace and abdomen, this limited on each side on the carapace by a 
black stripe below which is a testaceous stripe of about the same 
width, this enclosing some dark dots, the margins darker; on the 
abdomen the median stripe is limited on each side by a dark brown 
stripe, the sides and venter of abdomen pale, brownish grey with 
numerous small dark dots. Sternum yellow or dilute light brown 
minutely spotted with black and with a median longitudinal black 
line on caudal half. Labium and endites yellow or testaceous. 
Legs brown, the coxae and the femora beneath paler; femora marked 
above with longitudinal blackish lines and the legs elsewhere minutely 
spotted and streaked with dark. Chelicera each with a black longi- 
tudinal stripe down its front face. 
' Gosiute tuna, straight, and nabo, a mark.
