Numerous examples. 
y. The elytral spots ochreous, larger, the scutellar patch obsolete ; the thorax without markings. 
Hab. Panama, Volcan de Chiriqui (Champion). 
One example. 
6. The elytral spots golden-yellow, ochreous, or fulvous, still larger—the anterior ones rounded or slightly 
oblong, the posterior ones showing a tendency to form a broad fascia interrupted at the suture,—the 
scutellar patch large; the thoracic markings larger and more distinct, the triangular mark at the base 
extending forwards and nearly meeting the anterior 1-shaped mark, so as to partly enclose a large spot 
of black pubescence. (Fig. 16.)

(Conradt) ; Nicaracua, Chontales (Belt); Panama, Chiriqui (7'ré¢sch). 
Obtained in plenty by myself on the Pacific slope of Guatemala.. 
e. The elytral spots ochreous or fulvous, exceedingly large—the anterior ones oblong, the posterior ones forming 
a very broad anteapical fascia narrowly interrupted at the suture,—the scutellar patch obsolete or very 
small; the thorax without markings. (Fig. 17.) 
Hab. Mexico, Yolotepec (Sallé), Cerro de Plumas (Hoge); Guatemaa, El Tumbador,

Six examples. 
Z. The elytral spots ochreous—the anterior ones minute, the posterior ones in the form of a broad anteapical 
fascia narrowly interrupted at the suture,—the scutellar patch obsolete; the thorax without markings. 
Hab. Guatemaa, Calderas, Capetillo (Champion). 
Two examples. 
yn. The elytral spots ochreous or fulvous—the anterior ones and the scutellar patch entirely obsolete, the

without markings, 
Hab. Guatemata, Capetillo, Duefias, San Gerénimo (Champion). 
Three examples. 
6. As in y, but with the posterior spots narrowing behind and extending nearly to the apex (occupying nearly

Three examples. 
This is one of the finest of the Central-American species of Mordellide. There can
