CHOLUS. 301 
flattened between the coxe. Femora each with a short tooth. Tibize with the hook at the outer 
apical angle short and blunt (absent on two of the legs). 
Length 12, breadth 6 millim. (9 ?.) 
Hab. Muxico (Sallé, ea coll. Sturm). 
One specimen, abraded above, apparently female (the rostrum being almost smooth), 
though the abdomen is depressed at the base. Somewhat resembling the Nicaraguan 
C. viduatus, but with the elytra shorter and at the sides forming an almost continuous 
outline with the prothorax, the seriate punctuation much less interrupted, and the 
white spots absent, the rostrum very long and comparatively slender, the mesosternum 
flattened between the coxe, the hook at the outer apical angle of the tibiz short. The 
elytra are much less narrowed behind than in C. mudtiguttatus, the general shape being 
oval, not rhomboidal. 
22. Cholus foveolatus, sp.n. (Tab. XVI. figg. 1, 1a, ¢.) 
Elongate, rather narrow, subrhomboidal, black, shining, somewhat thickly clothed with oval, ochreous scales, 
which on the prothorax and elytra are condensed into spots in the depressions of the surface, the 
vestiture of the legs piliform. Head finely punctured and foveate between the eyes; rostrum stout, 
curved, slightly longer than the prothorax, rugulosely punctate at the sides, smoother along the centre 
and towards the apex. Prothorax nearly as long as broad, subconical, strongly constricted in front, 
the surface irregularly, confluently foveolate. Scutellum rather large and prominent. Elytra rapidly 
narrowing from the base, elongato-cordate, considerably wider than the prothorax; irregularly seriato- 
foveolate, the fovese here and there transversely or longitudinally confluent, the interstices smooth 
and uneven, becoming more regular and subcariniform towards the sides. First and second ventral 
segments deeply depressed down the middle in the g¢. Mesosternum flattened between the coxe. 
Femora each with an acute tooth. 
Length 15-16, breadth 64-63 millim. (¢ 9.) 
Hab. Costa Rica, Irazu, Rio Sucio (Rogers). 
In this insect the prothorax and elytra are foveolate and the fovee densely squamose, 
the rest of their surface being smooth, bare, and shining, a form of sculpture foreign 
to the other Central-American members of the genus. ‘Two specimens. 
23. Cholus confluens, sp. n. (Tab. XVI. figg. 2, 2a, ¢.) 
Subelliptic, narrow, black, shining; somewhat thickly clothed above and beneath with rather coarse, narrow, 
elongate, yellowish-white scales, which are condensed into a short transverse fascia at the sides before 
the middle and a common transverse fascia on the disc at about one-third from the apex, the vestiture ot 
the legs whitish and piliform. Head rugosely punctate between the eyes; rostrum stout, curved, longer 
than the prothorax, rugosely punctate and obsoletely carinate to about the middle and smoother thence 
to the apex. Prothorax transverse, rounded at the sides, much narrowed and feebly constricted in front, 
coarsely, confluently granulate. Scutellum transverse, squamose. Elytra considerably wider than the 
prothorax, elongato-cordate, the basal margin raised; coarsely, confluently granulate, the granular 
elevations becoming small, rounded, and separate towards the apex, the usual seriate punctuation deep 
and foveiform to beyond the middle. Beneath somewhat closely, finely punctate; first ventral segment 
depressed down the middle, and the fifth densely pubescent at the apex, in the ¢. Mesosternum 
flattened between the coxe. Femora each with an acute tooth. 
Length 11, breadth 43 millim. (¢.)
