296 RHYNCHOPHORA. 
12. Cholus limbatus, sp. n. (Tab. XV. figg. 14, 144, ¢ .) 
Subelliptic, flattened above, black ; the prothorax with the sides broadly, and the elytra with a broad vitta on 
the outer part of the disc, extending from the base to the apex, but not reaching the suture posteriorly, 
and the margins to about the middle, thickly clothed with oval or rounded, fulvous, shining scales, the 
upper surface also with scattered yellow scales, which are here and there condensed into small spots on 
the disc of the elytra; the vestiture of the legs sparse and yellow, that of the under surface coarser, 
scattered, fulvous and yellow intermixed. Head punctured and foveate between the eyes; rostrum stout, 
curved, rugulosely punctate at the sides, smoother towards the apex and along the centre. Prothorax 
transverse, rapidly narrowing from a little before the base to the apex, the sides rounded posteriorly, 
closely granulate laterally and at the base, the dise much smoother and faintly punctate. Scutellum 
cordate, flattened. Elytra at the base much wider than the prothorax, elongato-cordate, transversely 
depressed below the basal margin; seriate-punctate, the interstices and stric each seriate-granulate. 
Mesosternum strongly transversely swollen between the coxe. Legs long; intermediate and posterior 
femora each with an acute tooth, the anterior pair unarmed. 
Length 164, breadth 73 millim. (2.) 
Hab. Panama, Tolé (Champion). 
Narrower than C. cinctus (Drury), the vittee broader and fulvous in colour, the pro- 
thorax relatively narrower and with the disc smoother, the mesosternum protuberant, 
the anterior femora unarmed. One specimen. 
13. Cholus calvescens, sp. n. (Tab. XV. figg. 15, 15 a, 8, ¢; 16, 2, var.) 
Rhomboidal, black, shining ; the prothorax with a broad oblique vitta on the flanks running downwards from 
the base above, which sometimes has a branch extending forwards along the outer part of the disc, and 
the elytra—except the base, a large, common patch or transverse fascia at the middle (sometimes small 
and divided at the suture), a spot in a line with this at or near the margin, and a large oblong patch at 
the sides posteriorly—densely clothed with small, shining, oval, white or yellowish-white scales, these 
also extending across a broad space on the metasternum and on to the posterior angles of the ventral 
segments, the rest of the vestiture very sparse and piliform. Head rugulosely punctate and shallowly 
foveate between the eyes; rostrum stout, curved, longer than the prothorax, rugulosely punctate, 
smoother in the 9. Prothorax a little broader than long, subconical, slightly rounded at the sides behind, 
very minutely punctate and at most obsoletely granulate. Scutellum subcordate. Elytra very much 
broader than the prothorax, subcordate, the apices sometimes feebly caudate in the ¢; seriate-punctate, 
the punctures somewhat distant one from another, becoming coarser towards the base, and separated by 
flattened, rounded, almost obsolete granules, the interstices flat and each witha series of similar granules, 
which become more distinct at the apex. Ventral segments very sparsely punctate, 1 and 2 broadly 
depressed down the middlein the g¢. Mesosternum strongly protuberant between the coxe. Intermediate 
and posterior femora each with an acute tooth, the anterior pair unarmed in the ¢ and sometimes with 
a small tooth in the ? ; anterior and intermediate femora and tibie more or less ciliate within in 
the g. 
Length 135-18, breadth 61-83 millim. (¢ 2.) 
Hab. Panama, Volcan de Chiriqui (Champion, Trotsch). 
Var. costaricensis, n. 
The white squamosity of the elytra reduced to a sharply defined ante-median and a subapical fascia, the latter 
extending down the suture to near the apex. (Fig. 16.) 
Hab. Costa Rica (Van Patten), Caché (Rogers). 
Seven examples, three from Costa Rica and four from Chiriqui. This insect is not
