Brazilian Baring 295 



Form, sculpture and scanty vestiture nearly similar, except that on the elytra 

 the strial intervals are more feebly punctato-rugose, so that the individual 

 confused punctures, though smaller, are very much better defined and rather 

 well separated; color dissimilar, piceous-black, the legs longer; beak dis- 

 tinctly longer than the elytra, almost as in compacta, but the first funicular 

 joint of the antennae is longer; prothorax less abbreviated, only a fifth wider 

 than long, the sides feebly converging from the base and just visibly arcuate, 

 more rapidly rounding and oblique in apical third to the tubulation, which 

 is wider, nearly half as wide as the base; sculpture of dense longitudinal 

 ruga nearly similar; scutellum more narrowed from apex to base; elytra 

 similar in outline, but with rather more prominent, obtuse humeri and still 

 more distinctly wider than the prothorax, barely one-half longer; grooves 

 much less coarse than in either of the preceding; intervals strongly alter- 

 nating in width. Length 2.7 mm.; width 1.35 mm. Brazil (Santarem). 

 A single female example fusca n. sp. 



The two females that I have associated with the male type of 

 inflatula, are not quite so stout and have the elytra slightly though 

 obviously wider than the prothorax, the latter not inflated as it is 

 in the male. This is probably a genus confined to the Amazon 

 Valley. 



Ethelda n. gen. 



The small and narrow, densely squamose species forming the 

 type of this genus, greatly resembles an unusually densely clothed 

 Nicentrus to external view. The beak is short and thick, very 

 feebly arcuate and not separated from the head by any kind of an 

 impression. The antennae are slender, inserted at apical fourth of 

 the beak, the first funicular joint as long as the next three, the 

 club small, narrowly oval and rather abrupt, with its basal segment 

 somewhat more than half the length. The prosternum is nearly 

 flat, the coxae rather approximate, separated by scarcely a third 

 their width. The legs are somewhat slender and normal, the 

 prothorax subcylindric and not tubulate at apex, the basal lobe 

 small, the scutellum very densely squamose and the elytra with the 

 moderate striae almost concealed by the dense scaly covering. The 

 type is as follows: 



Ethelda squamosa n. sp. — Narrow, elongate-suboval and black, very densely 

 clothed with large and nearly white scales,, slightly separated on the metasternum 

 and abdomen; beak squamose, except at apex, and feebly sculptured, compressed, 

 feebly tapering and only four-fifths as long as the prothorax, the antennae dull 

 rufous; prothorax as long as wide, the parallel sides nearly straight, gradually 

 broadly arcuate beyond the middle; punctures moderate, dense; elytra almost 

 one-half longer than wide, elongate-elliptic, more than a fourth wider than the 

 prothorax and fully twice as long, the humeri not prominent, descending obliquely 

 upon the base; striae not fine, abruptly grooved, each of the small punctures along 

 the bottom of the grooves bearing a scale as large as those of the intervals and 

 almost exactly similar to them, so that, when perfect, the surface is homogeneously 

 squamose throughout; male abdomen feebly impressed and a little less squamose 

 medio-basally. Length 2.4 mm.; width 0.85 mm. Brazil (Uacarizal). Feb- 

 ruary. One specimen.
