CHOLUS. 297 
unlike C. pretorius, Pasc., from Panama, but has a relatively narrower subconical 
prothorax, the squamosity is whitish and differently distributed, and part of the upper 
surface is bare and shining. The whitish scales, as in C. lacordairei, sometimes cover 
the greater part of the elytral surface. In one of the Chiriqui specimens the vestiture 
is yellowish. 
14. Cholus xanthospilus, sp.n. (Tab. XV. figg. 17, 174, b, 3.) 
Subrhomboidal, black, shining; the prothorax with a curved or oblong mark on each side at the base, and the 
elytra each with from 8-10 small spots on the basal third and various others at or beyond the middle, 
these latter sometimes aggregated into an irregular transverse fascia, densely clothed with oval, 
ochreous scales, the ventral segments also with similar ochreous spots at the sides, the vestiture of the 
rest of the under surface and the legs whitish and piliform. Head finely punctate, feebly foveate between 
the eyes; rostrum stout, curved, much longer than the prothorax, in the d rugulosely punctate at the 
sides, and smoother along the centre and towards the tip, in the 2 almost smooth throughout. Prothorax 
transverse, subconical, a little rounded at the sides behind and feebly constricted in front, sparsely, finely, 
irregularly punctate, the flanks obsoletely granulate. Scutellum subcordate. Elytra much wider than 
the prothorax, subcordate ; seriate-punctate, the interstices flat and faintly granulate, the granulation 
becoming more distinct at the apex. Mesosternum protuberant between the coxe. First and second 
ventral segments broadly depressed down the middle in the g. Intermediate and posterior femora each 
with an acute tooth, the anterior pair unarmed. Anterior tibie strongly ciliate at the apex within in 
the ¢. 
Length 143-164, breadth 63-74 millim. (dc 2.) 
Hab. Nicaragua, Chontales (Belt, Janson); Costa Rica, San Carlos (ex Mus. 
Dresd.). 
Three specimens. This is the only Central-American Cholus with sharply-defined 
ochreous spots on the elytra, these being mainly concentrated towards the base and on 
the apical third, where they sometimes form an irregular transverse fascia. 
15. Cholus conicicollis, sp.n. (Tab. XV. figg. 18, 184, 3.) 
Subrhomboidal, a little flattened above; black, shining, somewhat thickly clothed with very small, narrow 
scales, which are ochreous on the prothorax and flavo-cinereous on the elytra, the vestiture of the under 
surface and legs whitish and ochreous intermixed, the ventral segments almost bare. Head foveate and 
closely punctate between the eyes; rostrum stout, curved, longer than the prothorax, rugulosely punctate 
at the sides, smoother along the centre and at the apex. Prothorax transverse, subconical, constricted in 
front, subgranulate and minutely punctate. Scutellum rather large and somewhat convex. Elytra very 
much wider than the prothorax, subcordate ; seriato-granulate, the granules smooth, bare, and closely 
placed, the interstices each with an irregular row of less closely placed, similar elevations. Ventral 
segments very sparsely punctate, the first and second depressed down the middle in the ¢. Mesosternum 
protuberant between the cox. Intermediate and hind femora each with a sharp tooth, the anterior 
pair unarmed, Anterior tibie strongly ciliate on the inner side towards the apex. 
Length 16, breadth 73 millim. (¢.) 
Hab. Costa Rica (Van Patten). 
One specimen. Distinguishable by the conical prothorax, the subcordate, closely 
seriato-granulate elytra, the protuberant mesosternum, and the unarmed anterior 
femora. The granular elevatious on the elytra are small and flattened.
