ZYGOPS. 27 
8. Zygops quadridentata, sp.n. (Tab. II. figg. 18, ¢; 184, hind leg.) 
Subelliptic, broad, flattened above, nigro-piceous, the antenne obscure ferruginous ; the vestiture dense and 
fine, fulvous-brown, the head with a line around the eyes, and the prothorax with a faint median line 
and a narrow, sinuous, oblique stripe on each side, whitish, the elytra with widely scattered black and 
whitish spots, a black excised patch near the suture at about the middle being larger than the rest, the 
pygidium with a whitish median line; beneath flavo-cinereous, slightly mottled with brown along 
the sides, the fifth ventral segment with a brown spot on each side; the legs flavo-cinereous, the 
posterior femora brown at the apex. Eyes narrowly separated ; rostrum arcuate, rugosely punctate 
and feebly tricarinate at the base; joint 2 of the funiculus about one-half longer than 3. Prothorax 
transverse, feebly bisinuate at the base, the sides sinuate and rapidly converging from the middle 
forwards ; densely, minutely punctate. Elytra much wider than the prothorax, transversely depressed 
below the base, slightly rounded at the sides, obtuse at the apex; finely punctate-striate, the interstices 
densely punctulate, flat, 1 granulate from the base to the apex. Ventral segments 1 and 2 broadly 
excavate down the middle. Legs rather short, the posterior femora extending slightly beyond the apex 
of the abdomen ; posterior femora 4- or 5-, and the others 2-, dentate, the former with a rather long, 
truncated plate at the outer apical angle. 
Length 93-10, breadth 47-5 millim. (<¢.) 
Hab. Mexico, Toxpam in Vera Cruz (Sallé). 
Two males. A rather large, broad, robust form, subelliptic in shape, with the legs 
comparatively short and the posterior femora armed with three or four small teeth 
exterior to the larger one, the outer lobe at the apex produced into a broad truncated 
plate. The elytra are marked somewhat as in Z. trivittata. Various nearly allied 
species occur in South America, but they want the long lamella at the apex of the 
posterior femora. 
9. Zygops amenula, sp. n. (Tab. II. figg. 19, 19a, 2.) 
Zygops amenula, Jekel, in litt. 
Elongate-ovate, rather convex, black, the antenne ferruginous at the base ; densely clothed with small scales : 
the head with a A-shaped fulvous or white mark between the eyes, the prothorax with a broad, transverse, 
arcuate fascia on the basal portion of the disc, and a broad oblique stripe behind the eyes, black, the 
intervening space fulvous, the outer and inner basal portions and the scutellum white, the elytra black, 
each with four or five fulvous, white-edged spots (the three larger ones placed in an irregular longitudinal 
series on the disc, the posterior one curved, the others small and exterior to the first), the pygidium 
black, white at the sides and along the middle; the vestiture of the under surface very dense, white, 
the mesothoracic episterna in part, a space between the middle and posterior cox, and the sides of the 
first ventral segment, black ; the anterior and intermediate femora, and a patch on the hind pair above, 
white, the rest of the vestiture of the legs in great part black. Eyes very large, almost contiguous in 
front; rostrum strongly arcuate, moderately long, unicarinate and rugulose at the base; joints 2 and 3 
of the funiculus elongate, 2 twice the length of 8. Prothorax transverse, subquadrate, narrowed in 
front, very feebly bisinuate at the base; densely, minutely punctate. Elytra oblong, slightly wider 
than the prothorax, truncate at the base and obtuse at the apex; finely and shallowly punctate-striate, 
the interstices densely punctulate, flat, 1 feebly granulate. Legs rather short ; posterior femora tri-, 
the others bi-, dentate, the posterior pair about reaching the apex of the abdomen. 
Length 63-63, breadth 24 millim. (92?) 
Hab. Nicaracta, Chontales (Belt).—Sourn America, Rio Janeiro, Paré (Mus. brit.). 
Three specimens of this species have been received from Chontales. The elongate 
shape, the black elytra, ornamented with large, fulvous, white-edged spots, the curved,
