Collum with its anterolateral angles quite salient, as in plate 5, 
figure 10; its color yellow, a median transverse spot dark brown. 
Anterior lobe of pronotum without lateral spines or tubercles; discal 
‘spines very long and slender (length, 1.5 mm.), almost vertical. Color 
of this lobe entirely yellow, only the discal spines and their base brown- 
ish. Posterior lobe yellow, with brownish design as in plate 6, figure 
26. Humeral angles directed upwardly and backwardly, approxi- 
mately as long as discal spines of anterior lobe, uniformly dark piceous. 
Median longitudinal impression occupying the whole anterior lobe of 
pronotum; the longitudinal carinae short, beginning behind the discal 
spines and terminating near the base of posterior lobe; the latter with 
very numerous transverse or irregular wrinkles. Prosternal processes 
distinct, not very long. Mesosternum with a median Y-shaped 
carina; metasternum with a transverse carina. Pleura very hairy; 
hairs long, delicate, and brightly colored. Sterna with similar 
pubescence. 
~ Seutellum yellow, with a large, median, longitudinal, dark-brown

is almost vertical, yellow on its distal two-thirds, and with a total 
length corresponding to that of the pronotal spines. 
Legs slender, not very long, the posterior ones the longest. Ventral 
face of anterior femora with two longitudinal parallel rows of small 
dentiform processes, a few noticeably larger than the majority; the 
rows begin near base and attain the apex; median femora similar. 
Anterior and median tibiae with numerous small dentiform processes ; 
spongy fossa occupying one-fourth of total length of anterior tibia. 
Tibia with strong dark bristles, the length of which is two to three times 
the diameter of said structure. Color of legs distinctly yellow or 
orange, with brownish annuli. Anterior and median femora with one 
median, one subapical, and one apical dark ring; posterior femora with 
one median and one apical ring; tibiae of all pairs with one submedian 
and one apical dark ring. 
Hemelytra attaining apex of abdomen; their design is shown in 
plate 6, figure 26. 
Median longitudinal keel on ventral face of abdomen attaining base 
of third segment. Connexival margin of second segment with a very 
small tooth. Delicate long hairs present, not very numerous. Gen- 
eral color of ventral face of abdomen pale yellow; sutures between 
third and fourth, fourth and. fifth, fifth and sixth, and sixth and
