184 RHYNCHOPHORA. 
6. Pantoteles dimidiatus, sp. n. (Tab. XI. fig. 2*, ¢-) 
Oblong-ovate, opaque, nigro-piceous, the antennae (the club excepted) ferruginous; the head, the prothorax 
with the sides, flanks, and a faint median line, the apical half of the elytra, the meso- and metasternum 
(except at the sides), and the ventral surface, thickly clothed with small flavo-cinereous scales; the rest 
of the upper and under surfaces sparsely set with brownish scales, appearing almost bare. Head densely, 
finely punctate, suleate between the eyes; rostrum almost straight, slender, a little longer than the 
prothorax, depressed at the base, sparsely finely punctate. Prothorax transverse, rather convex, 
constricted and much narrowed in front; densely, finely punctate. Elytra moderately long, a little wider 
than the prothorax, gradually narrowing from the base, the humeri somewhat swollen ; finely punctate- 
striate, the interstices flat, densely punctulate. Ventral segments 1 and 2 depressed down the middle. 
Legs comparatively short and stout ; tarsi rather broad, the anterior pair with a few projecting hairs, 
the claws small. 
Length 54, breadth 23 millim. (d.) 
Hab. Panama, Bugaba (Champion). 
One specimen, perhaps a little worn. Less elongate than P. tenuirostris, the apical 
half of the elytra densely, uniformly squamose (the scales coarser, a few of them 
extending forward along the edges of the striz), the legs shorter and stouter, the tarsal 
claws smaller. Ambates posticus, Kirsch, from Colombia, has the vestiture of the 
elytra somewhat similarly coloured. 
7. Pantoteles albocinctus, sp.n. (Tab. XI. figg. 3, 3a, 3.) 
Elongate-elliptic, dull, black; the prothorax with the sides broadly, the elytra with a very broad, common, 
transverse fascia below the base (extending downward on to the metasternum) and a large, common, 
somewhat heart-shaped, patch on the disc towards the apex, and the under surface (the mesothoracic 
side-pieces, a broad space at the sides of ventral segment 1, and a narrow space along the middle of 
segments 3-5, excepted), densely clothed with rather coarse whitish scales, the rest of the vestiture of the 
elytra sparser, blackish, the median third of the prothorax and the head and rostrum almost bare. 
Rostrum feebly arcuate, moderately stout, flattened at the tip, sparsely punctate at the base, and almost 
smooth thence to the apex, the scrobes lateral. Joint 1 of the funiculus longer than 2. Prothorax 
broader than long, rapidly narrowing from the base, the sides somewhat rounded; densely, finely, 
confluently punctate, with indications of a smooth median line. Elytra much wider than the prothorax, 
elongate-triangular; finely punctate-striate, the interstices rugulose. Prosternum feebly sulcate. 
Anterior coxse separated by a narrow lamella only. Ventral segment 1 depressed in the centre posteriorly, 
3 and 4 with a narrow smooth space down the middle, and 5 shallowly foveate at the apex. 
Length 74, breadth 31 millim. (¢.) 
Hab. Costa Rica, Caché (Rogers). 
One specimen, somewhat badly preserved. The broad, transverse, whitish fascia on 
the elytra is in this species continued round the metasternum, a common, large, heart- 
shaped patch on the disc towards the apex and the sides of the prothorax being also 
whitish. The elongate-elliptic shape, and the very narrowly separated anterior coxe, 
also help to distinguish P. albocinctus. ‘The rostrum is stouter and more curved than 
in the other species here referred to Pantoteles. 
* The insect is more elongate than represented by our artist on the Plate.
