into the club without trace of differentiation of the latter, except 

 in its dense gray vestiture and deep sutures; the basal joint of the 

 funicle is not quite half as long as the remaining joints, which are 

 strongly transverse and compactly connected. The beak is thick 

 and arcuate, the prothorax broad and scarcely at all constricted 

 at apex, the flat scutellum in close and even contact with the 

 thoracic lobe and elytra, the prosternum feebly impressed and the 

 coxae well separated. The type is as follows: 



Spolatia gradata n. sp. — Body faintly subrhombic-oval, very smooth, polished, 

 glabrous and deep black throughout; beak as long as the prothorax, thick, 

 subcylindric and arcuate, minutely and loosely punctulate and polished through- 

 out, separated by a moderate transverse impressed line; antennae blackish, 

 medial, with short scape, the club a little longer than the preceding three joints; 

 prothorax a fourth wider than long, the sides slightly converging and almost 

 straight to about the middle, there rounding, becoming more converging but 

 scarcely arcuate to the broad and feeble apical sinuses; apex truncate, four- 

 sevenths as wide as the base; surface extremely smooth and devoid of any kind 

 of sculpture throughout, the basal lobe short and gradual, with truncate apex 

 and minute feeble lateral impressions; scutellum somewhat wider than long, 

 broadly ogival, truncate at base, very smooth and flat; elytra a fifth longer 

 than wide, evidently wider than the prothorax and two-thirds longer, the oblique 

 sides only feebly arcuate, rapidly rounding at apex, the latter broadly obtuse; 

 humeri broadly rounded, only slightly prominent; striae extremely fine, feeble 

 and impunctate, the sutural but little more marked and remotely subpunctulate; 

 sterna rather strongly but loosely punctate, the abdomen minutely and sparsely 

 so, smooth, not modified at base in the type; femora slender, finely, sparsely 

 punctulate, the anterior with a very small obtuse tooth beneath. Length 3.3 

 mm.; width 1.8 mm. Brazil (Santarem). One specimen. 



The antennae in this genus, with their remarkably compact 

 form and completely undifferentiated club, constitute one of the 

 exceptional developments in the subfamily. 



Linogarnia n. gen. 



This is another genus, which, although monotypic, is rendered 

 necessary by a different form of scutellum, this being widely sepa- 

 rated from the surrounding elytra and thoracic lobe, or what 

 might be termed free. The beak is rather long, feebly tapering 

 and subcompressed at the sides basally, not separated from the 

 head by a sharply marked reentrant angle, the antennae submedial, 

 the funicular joints broader distally but not very compact, the 

 first longer than the next two, the second twice as long as wide, 

 the club oval, clearly segmented, somewhat abruptly formed and 

 nearly as long as the preceding four joints. The prosternum is 

 narrowly and shallowly channeled, the coxae only very moderately 

 separated, the femora rather thick but subparallel and unarmed, 

 and the tarsal claws are somewhat long and strongly connate at
