Brazilian Barin/e 189 



suboval, the beak long, thin, separated from the head by a rather 

 abrupt, deep and conspicuous sulcus, and with slightly dentate 

 mandibles, prominent when closed, the antennae slender, submedial, 

 with moderate narrowly oval club and notably elongate first 

 funicular joint. The prosternum is slightly excavated anteriorly, 

 and the coxae are well separated, the femora unarmed and not 

 inflated and the tarsal claws free and widely diverging. The elytra 

 always have dense pale vestiture, sharply confined to one or two of 

 the discal strial intervals— three for a short distance medially in 

 volximi— the pronotum with dense oblique lateral pale vittae, and 

 the under surface is unequally clothed, the met-episterna and apical 

 part of the prosternum generally more densely. The genus includes 

 four groups as follows: 



Elytra with the third and fourth intervals densely clothed with pale scales at 

 least in part, the eighth and ninth, also, in longirostns; male with long 

 conspicuous, apically upturned ante-coxal processes, the beak very long 

 slender and strongly arcuate ,"."," ,' " " * "/ " 



Elytra with intervals 2-4 densely clothed with pale scales in a little less than 

 median third of the length, the lateral pronotal vittae as in the preceding. . II 



Elytra with only the fourth interval densely and pallidly squamose, but not 

 quite to the apex; beak very long; prosternum (c?) with two very long 

 porrect ante-coxal processes, turned downward at apex; lateral pale pronotal 

 vitta more separated from the margin • • ■ • ■ } li 



Elytra similarly with only the fourth discal interspace densely and pallidly 

 squamose and likewise not quite to the apex, but, in addition, with the 

 sutural interval also narrowly and less densely pallido-squamose; lateral 

 pronotal vitta also remote from the margin, though dilated to the latter at 

 base; beak not so long and less arcuate, the prosternum unarmed in the 

 male ,;.' ' ' ' . . - ■ ■ ••'.'. 



I— Elytra with the eighth and ninth intervals densely pallido-squamose, in addition 

 to the third and fourth; beak extremely slender and arcuate and much 

 longer than the elytra in the female. Body very elongate, rhombic-oval, 

 moderately convex, all the pale scales above and beneath whitish, the dense 

 lateral pronotal vittae slightly separated from the sides, except at base, the 

 vitta of the third interval meeting the lateral double vitta at apex on each 

 elytron, that of the fourth interval slightly abbreviated near the apex; on 

 the under surface the pale scales are dense toward the sides almost throughout 

 and uniform, finer on the prosternum and with a large oval denuded lateral 

 space; beak as long as the elytra (cT), almost as long as the body and very 

 slender ( 9 ), and strongly arcuate in both sexes but especially in the female; 

 antennae obscure rufous, very long and slender, the narrow club much shorter 

 than the first funicular joint, the second three times as long as wide; prothorax 

 one-half (<?) to three-fifths (9) wider than long, the converging sides sub- 

 evenly arcuate to the tubulation, which is less than half as wide as the base; 

 punctures moderate and distinctly separated, almost nude the impunctate 

 median line well defined, fiat; basal lobe distinct, rounded, the scutellum 

 glabrous, subquadrate, sinuato-truncate ; elytra one-half ( c? ) to three-sevenths 

 ( 9 ) longer than wide, parabolic, wider than the prothorax and almost two 

 and one-half times as long; grooves deep, a third to fourth as wide as the 

 intervals, which are densely clothed with smaller dark brown scales; abdomen 

 (o") acutely impressed medio-basally, the prosternal processes long, evenly
