Brazilian Baring 357 



similar; male abdomen finely, densely punctate throughout, the meta- 

 sternum less coarsely and more densely punctate than in the preceding; 

 sexual modifications not noticeable; pygidium similarly small, vertical and 

 transversely suboval. Length 4.2 mm.; width 1.7 mm. Brazil (Santarem). 

 One male specimen thoracicus n. sp. 



3— Body much smaller than in either of the preceding, but nearly similar in 

 general form, color and lustre; beak very thick, barely arcuate, compressed, 

 shining and distinctly shorter than the prothorax, which is not quite as long 

 as wide, the parallel sides evenly and feebly arcuate, gradually rounding in 

 about apical third to the distinct tubulation, which is more than half as wide 

 as the base; punctures fine but not quite so minute, sparse, gradually very 

 little less fine, slightly closer and longitudinally ruguliform laterally; elytra 

 about one-half longer than wide, parallel, obtusely and circularly rounding 

 behind, with almost obsolete humeri, not wider than the prothorax and 

 three-fourths longer; grooves throughout nearly as in femoralis; first ab- 

 dominal segment coarsely but shallowly punctate, the second more finely, 

 the last three finely and still more densely punctate, the sterna somewhat 

 coarsely punctate, the inferior thoracic flanks more deeply, longitudinally 

 rugulose than in either of the preceding; abdomen feebly impressed at the 

 middle of the base in the type. Length 3.0 mm.; width 1.18 mm. Brazil 

 (Santarem). One male specimen parvulus n. sp. 



4— Form elongate-subparallel or feebly ovulate, rather more convex, similar in 

 color and lustre; beak (d") rather less thick and more arcuate, fully as long 

 as the prothorax, less compressed and with the antennae but little beyond 

 the middle and blackish; prothorax a fifth wider than long, the sides parallel 

 or nearly so, and straight beyond the middle, gradually more strongly 

 rounding to the tubulation, which is somewhat more than half as wide as 

 the base; punctures minute and sparse, gradually more distinct and longi- 

 tudinally rugulose toward the sides, but not at all dense; elytra three-fifths 

 longer than wide, with just visibly oblique and very feebly arcuate sides, 

 gradually rounded apex and distinctly tumid humeri, very slightly wider 

 than the prothorax and nearly twice as long, the grooves throughout nearly 

 as in femoralis, except that the inner ones become basally simple series of 

 well spaced punctures; male abdomen without sexual modification, very 

 gradually more finely and densely punctate from base to apex. Length 

 365-39 mm.; width 1.4-1.6 mm. Brazil (Santarem). Two male speci- 

 mens parallels n. sp. 



No information is recorded concerning the habits of these species, 

 which, though adhering to a common external habitus, are clearly 

 distinct among themselves. 



Anazalinus n. gen. 

 The type of this genus is a very small, exactly parallel and 

 subcylindric, polished black and glabrous species, allied to the 

 preceding in many features, but differing quite radically in others. 

 The beak is short, rather thick, feebly arcuate and evenly cylindric, 

 not at all compressed, smooth and not separated from the front by 

 a distinct impression, although there is a median puncture as in 

 Zalinus, and the mandibles are also similar. Antenna? medial, short 

 and rather thick, the first funicular joint as long as the next two,
