Brazilian Barin/e 177 



of Eiidialomia, for which I would propose the name Dialomiaspis 

 (n. subgen.). The thoracic lobe, distinct in remota and altogether 

 wanting in longida, the type of Eudialomia, together with the undu- 

 lated elytra of longula and complete absence of this character in 

 remota, would seem to warrant this distinction. 



Leptoladustes n. gen. 



The body in this genus is elongate-oval, convex and very densely 

 sculptured, with a mixture of darker and pale squamules somewhat 

 loosely distributed. The beak is slender, evenly and feebly tapering 

 throughout, arcuate and strongly sculptured, separated from the 

 head by a moderate depression, the mandibles rather small, bifid 

 and decussate. The antennae are rather long and slender, medial, 

 the funicular joints loosely joined, not increasing much in width 

 distally, the first as long as the next two, the second not quite as 

 long as the succeeding two, although three times as long as wide, 

 the club very moderate, narrowly oval and as long as the four 

 preceding joints, with its first segment about half of the mass. 

 The prosternum is narrowly canaliculate and, in the male, has two 

 long slender porrect processes, separated by a very deep rounded 

 well, the coxae separated by nearly their own width. The legs are 

 rather long, the femora not distinctly inflated, mutic, the tibiae 

 very slender and the claw-joint of the tarsi not as long as the first 

 three joints, the claws long and widely diverging. The prothorax 

 is strongly tubulate at tip. The type is as follows: 



Leptoladustes densus n. sp. — Elongate-oval, opaque, uniform piceous-brown 

 in color, with strong dense, longitudinally confluent pronotal, and dense confused, 

 irregular and not very deep interstitial, punctuation, the entire under surface 

 with dense but not very coarse punctures, each having a small hair-like squamule; 

 on the pronotum the yellowish and rather long squamules are sparse and unevenly 

 distributed, more visible at the sides; on the elytra they are widely scattered, 

 with condensation at each side of the scutellum and on the humeri, also less 

 marked on the second interval near the middle; beak very evenly but moderately 

 arcuate and fully half as long as the body; prothorax as long as wide, the parallel 

 sides broadly arcuate, gradually more rounding and converging beyond the 

 middle to the tubulation, which is truncate and three-sevenths as wide as the base; 

 basal lobe rather small, rounded, with a cluster of pale squamules, the median line 

 smooth and slightly tumid but not evidently cariniform, almost nude; scutellum 

 subquadrate, impressed and nude; elytra evenly ogival, with narrowly rounded 

 tip, only slightly wider than the prothorax and four-fifths longer, the humeri not 

 prominent, oblique to the base; striae somewhat coarse, deep, groove-like but 

 not very smooth, a third as wide as the intervals; abdomen strongly, evenly 

 convex, finely, very evenly punctulate and with small slender squamules through- 

 out, not in the least impressed at base in the male. Length 4.1 mm.; width 

 1.85 mm. Brazil (Rio de Janeiro). November. One specimen. 



Readily recognizable by the narrowly oval form, dense sculpture,
