becoming abruptly rather coarse and longitudinally ruguliform at the sides; 

 scutellum transversely oval; elytra nearly one-half longer than wide, a fifth 

 wider than the prothorax and three-fourths longer, the oblique sides broadly 

 and feebly arcuate, the apex rather strongly, evenly rounded; humeri very 

 broadly, moderately tumid; grooves narrow, very coarse posteriorly; inter- 

 vals near base about five times as wide as the grooves, finely, sparsely punctu- 

 late along their median line, confusedly toward the humeri; abdomen (cf ) 

 convex, feebly impressed medio-basally; prosternal spines not quite half as 

 long as the prothorax; inner fringe of the anterior tibiae very short, and 

 inconspicuous. Length 8.0 mm.; width 3.85 mm. Brazil (Amazon Valley). 

 Two specimens valens n. sp. 



Prothorax not inflated, the sides gradually converging and evenly, very moder- 

 ately arcuate from base to constriction; body narrower, similar in color, 

 lustre and in the fine brown elytral set ae; beak (c?) fully as long, but some- 

 what thinner and more arcuate, especially beyond the middle, almost simi- 

 larly sculptured, the piceous antennae evidently beyond basal third; pro- 

 thorax about as long as wide, the tubulation and sculpture almost similar; 

 basal lobe narrower and more strongly rounded, the lateral impressions 

 almost similar; scutellum less transverse; elytra narrower, but otherwise 

 almost similar throughout, rather less than a fifth wider than the prothorax, 

 about two-thirds longer, the humeri less obtuse but not quite so prominent; 

 sculpture nearly similar, but with the interstitial punctures not more con- 

 fused toward the humeri; under surface in the male subsimilar, the prosternal 

 spines in the type a little less than half as long as the prothorax but, in a 

 second smaller specimen with somewhat shorter beak, they have the form 

 of short conical tubercles; inner fulvous fringe of the anterior tibiae very 

 long, dense and conspicuous, gradually diminishing toward base; anterior 

 tarsi with long and loose inner fringe. Length 5.9-7.0 mm.; width 2.75- 

 3.2 mm. Brazil (Amazon Valley). Two specimens exarata n. sp. 



Prothorax with more strongly arcuate sides than in the preceding, but less in- 

 flated than in valens, the body shorter and relatively stouter than in exarata, 

 the color and fine setae similar; beak (cf ) strongly arcuate and longer than 

 the elytra, sculptured as in valens, the blackish antennae a little behind the 

 middle; prothorax evidently shorter than wide, the distinctly and evenly 

 arcuate sides not becoming quite parallel at base, the lobe, sculpture and 

 tubulation nearly as in valens, the medio-apical sinus feebler; scutellum 

 smaller, transversely oval ; elytra as in exarata; abdomen similar; prosternal 

 spines a third as long as the prothorax; inner fulvous tibial fringe as in 

 exarata and very different from that of valens; tarsal claws similarly very 

 long and conspicuous. Length 7.3 mm.; width 3.35 mm. Brazil (Amazon 

 Valley) lobata n. sp. 



All of the above four specimens were received from Desbrochers 

 des Loges, without further indication of locality; one of them bore 

 the legend " Dactylocrepis n. sp., ex Jekel." There may be two 

 species united above under exarata, but so closely allied that no 

 definitive separation can be made at present, the material being 

 very scanty. The female is unknown to me in this genus.

Limnobaroides Chmp. 



The species of this genus are small, oval, rather convex, coarsely 

 sculptured and with more or less abundant slender squamules,
