124 RHYNCHOPHORA. 
towards the suture ; rather coarsely punctate-striate, the interstices feebly convex and closely, minutely 
punctate. Tibi unguiculate. 
Length 6,1, breadth 23 millim. ( 9.) 
Hab. Guatemaa, Cerro Zunil (Champion). 
One specimen. Narrower than C. bisignatus, and with the darker scales so arranged 
as to form two irregular fasciz on the elytra, the rostrum elongate. Narrower and more 
shining than C. rujirostris, the rostrum and antenne less elongate, the scales of the 
upper surface differently coloured. 
3. Ceratopus mixtus, sp. n. 
Oblong, rather broad, shining, piceous, the basal half of the antennz, the femora, and tibize rufescent; some- 
what thickly clothed with small, narrow, intermixed, flavo-cinereous and brown scales, which give a 
mottled appearance to the elytra, the latter with a conspicuous pallid spot on the fifth interstice towards 
the apex. Head finely punctate; rostrum about as long as the head and prothorax, closely punctate and 
finely carinate in its basal two-thirds, smoother thence to the apex; antenne rather stout, inserted at 
about one-third from the apex of the rostrum, joint 1 of the funiculus one-half longer than 2, the club 
as long as joints 47 united. Prothorax transverse, much narrowed and feebly constricted in front, the 
sides rounded before the middle and straight and slightly converging behind, the base bisinuate ; closely, 
finely punctate, with an abbreviated smooth median line. LElytra broad, more than one-half wider than 
the prothorax, subparallel towards the base, which is sinuate; punctate-striate, the interstices closely, 
minutely punctate, flat, the fifth convex at its apex. ‘libe mucronate. 
Length 8}, breadth 33 millim. (92.) 
Hab. Nicaragua, Chontales (Belt). 
One mutilated specimen. Near C. bisignatus, but much broader, the elytra especially, 
the base of the latter sinuate, like that of the prothorax, the squamosity finer and 
more mottled, the third elytral interstice raised at its apex. The tibie are simply 
mucronate at the apex. 
4, Ceratopus dorytomoides, sp.n. (Tab. VIII. figg. 6, 64, ¢ .) 
Oblong-ovate, piceous, or fusco-testaceous with the apical half of the elytra darker, the antenne (the club 
excepted) rufescent ; thickly clothed with small, oblong, fuscous or tawny scales, the elytra with a few 
very small patches of pallid scales scattered across the middle of the disc. Head densely, rugulosely 
punctate; rostrum (¢) a little shorter than the head and prothorax, rugulosely punctate to near the tip, 
and also longitudinally wrinkled, (@) longer and smoother, the apical half sparsely punctate; antenne 
inserted near the apex of the rostrum in the ¢, and at about one-third from the tip in the @, joint 2 of the 
funiculus much shorter than 1, the club about as long as joints 3-7 united. Prothorax strongly trans- 
verse, narrowed and constricted in front, the sides almost parallel behind; densely, very finely punctate. 
Elytra moderately long, subovate, about one-half wider than the prothorax, narrowing from about the 
middle, subtruncate at the base; finely punctate-striate, the interstices flat and densely, minutely 
punctate. Tibie unguiculate. First ventral segment depressed in the middle in the g. 
Length 5-6, breadth 2;-2% millim. (¢ Q.) 
Hab. Guatemaa, Cerro Zunil (Champion). 
One pair. A typical Ceratopus, differing from C. bisignatus in its smaller size, the 
‘posteriorly narrowed elytra, without conspicuous pale spot at the apex of the fifth 
interstice, the duller surface, &c. The male is very like Boheman’s figure of Acantho-
