NOTES ON ZELURUS—LENT AND WYGODZINSKY 345 
lobe smooth, posterior lobe irregularly wrinkled. Median longitudi- 
nal groove occupying almost the whole anterior lobe of pronotum, 
originating at level of bases of discal spines and thus also occupying 
the anterior three-fourths of the posterior lobe. Distal spine of 
scutellum strong, acute, being the longest of all thoracic spines. Pro- 
sternal processes not very prominent. 
Legs of medium length. Femora ventrally without any traces of 
denticles. Spongy fossa occupying one-third of the total length of 
the anterior tibia. Femora and tibiae with few bristles, the length 
of which is not greater than the diameter of the respective structures. 
Microhemelytra not reaching posterior margin of second tergite; 
length, 2.5 mm. Dorsal gland openings conspicuous at posterior bor- 
der of third, fourth, and fifth segments; a small median tubercle pos- 
teriorly on sixth segment. Connexivum inconspicuous dorsally, dis- 
tinct ventrally. Median longitudinal keel and sutures between ven- 
tral segments inconspicuous. 
Locality.—Cérdoba, Argentina (W. M. Davis). 
The specimen differs from Z. bergrothi Lent and Wygodzinsky in 
pronotal and abdominal characters (these may be the result of its 
brachypterous condition), but chiefly in its pointed jugae, which are 
similar to those found in Z. femoralis (Stal, 1854). However, it seems 
to us to be more closely related to the former, and therefore we con- 
sider it tentatively as the female of Z. bergrothi. 
ZELURUS SALYAVATOIDES, new species 
Priate 5, Figures 10-12; Pirate 6, Figure 26 
Female.—Length to apex of hemelytra, 12.5 mm.; distance between 
points of humeral spines, 4.5 mm.; maximum width of abdomen, 4.0 
mm. 
General color of body pale yellow, partly orange-yellow, with dark 
piceous design on its surface, as in plate 6, figure 26; only the antennae 
and the third segment of rostrum uniformly dark piceous. 
General form of head as in plate 5, figures 10 and 11; distance 
between eyes dorsally 114 times the width of one eye, as viewed in this 
plane. Anteocular and postocular region separated dorsally by a deep 
transverse groove. From the center of this groove there arises another 
short groove directed anteriorly. Jugae and genae rounded apically, 
not very protruding. Color of head dorsally, yellowish; base of 
ocelli and the above-mentioned grooves dark brown; laterally with 
dark-brown stripes before and behind the eyes; the bristles are long, 
delicate, and erect. 
Length of first segment of anterinae, 1.0 mm.; proportion of seg- 
ments one to four, 1:3:2.8:2.4. Rostrum as in plate 5, figure 11; basal 
half of first segment yellow, apical half dark piceous; the apical two-
