368 RHYNCHOPHORA. 
near the apex, the broad basal portion very shallowly arcuate-marginate. Anterior coxe separated by 
nearly twice their own width. Legs rather elongate, comparatively slender ; anterior and intermediate 
femora feebly. dentate; anterior tibize subangularly dilated on the inner side near the base; anterior 
tarsi slightly dilated and hairy. 
Length 6, breadth 2! millim. ( 9.) 
Hab. Panama, Volcan de Chiriqui 3000 feet (Champion). 
One specimen, evidently a female, to judge from the form of the rostrum and of that 
of the last ventral segment. Narrower and less cuneiform than J. velatipes, Kirsch, 
from Bogota, the prothorax less abruptly narrowed in front, the elytra obsoletely 
striate to near the apex, the anterior tibie dilated on the inner side near the base. 
M. tarsalis, Kirsch, from Bogota, is yet another allied form, both these insects having 
long, dilated, and very hairy anterior tarsi in the male sex. 
6. Madarus clavipes, sp. n. (Tab. XVIII. figg. 30, 30a, 2.) 
Broad, subfusiform, glossy-black, glabrous. Head finely punctate, unimpressed between the eyes; rostrum 
curved, as long as or longer than the head and prothorax, the basal portion thickened and rather coarsely 
punctate laterally, the longer apical portion sparsely, finely punctate, the antenne inserted far behind 
the middle. Prothorax large, moderately convex, broader than long, rounded at the sides, rapidly 
narrowed from the middle forwards, feebly constricted in front, deeply sinuate at the base; sparsely, 
very finely punctate, faintly strigose on the flanks. Scutellum arcuate. Elytra rapidly narrowed from 
the base, transversely depressed anteriorly ; very finely lineato-punctate, striate at the sides and apex, 
the interstices each with a row of excessively minute punctures. Pygidium densely punctate, about as 
long as broad. Meso- and metasternum coarsely punctate atthe sides, the rest of the under surface more 
finely punctured, the ventral segments 2-5 still smoother. Prosternum feebly bifoveate near the apex, 
the very broad basal portion subtruncate behind. Femora clavate, each with a very small tooth. 
Length 675-62, breadth 3 millim. (@.) 
Hab. Guatema.a, Chiacam in Vera Paz (Champion); Panama, Bugaba (Champion). 
Three specimens, varying in the length of the rostrum, but evidently all females. 
This insect is of about the same size and shape as WV. witiosus; but it has a relatively 
larger, less constricted prothorax, more even elytra, a broader scutellum, a non-sulcate 
prosternum, and feebly toothed, clavate femora. 
7. Madarus mirandillg, sp. n. (Tab. XVIII. figg. 31, 31@, ¢.) 
Klongate, subfusiform, glossy-black, glabrous. Head sparsely, minutely punctate, transversely depressed 
between the eyes; rostrum a little longer than the head and prothorax, arcuate, moderately stout, 
slightly thickened towards the base, finely punctate, the antenne inserted at the middle. Prothorax 
distinctly broader than long, subconical, feebly constricted in front; very finely, somewhat closely 
punctate. Elytra gradually narrowing from the base, transversely depressed anteriorly ; very finely and 
shallowly punctate-striate, the strie becoming deeper at the sides, the interstices minutely, confusedly 
punctate. Pygidium closely punctate. Meso- and metasternum coarsel y punctate at the sides, the rest 
of the under surface very sparsely and finely punctured. Pronotum unimpressed behind the transverse 
subapical groove, the basal process truncate, foveate in the middle posteriorly. Anterior coxee separated 
by rather more than their own width. Femora clavate, unarmed. 
Length 54, breadth 21 millim. ( 9.) 
Hab. GuaTeMaLa, Mirandilla, Pacific slope (Champion).
