having merely a rather narrower form of body, with stouter beak, 

 larger antennal club, transversely sublunate scutellum and larger 

 pygidium. The body is glabrous and polished, the beak rather 

 short, not tapering, arcuate, subcylindric and moderately punctate, 

 the mandibles very strongly, acutely dentate and decussate, and it 

 is separated from the head by a rather distinct sulcus. The an- 

 tennae are submedial (o 71 ) or post-medial ( 9 ), with short scape and 

 stem and large oval club, the first funicular joint as long as the 

 next three, the others increasing in width, very transverse and 

 compact. The fiat prosternum separates the anterior coxae by 

 scarcely their own width. The prothorax is not or very faintly 

 tubulate at apex, the basal lobe prominent and abruptly formed, 

 rounded at apex, the scutellum moderate in size, transversely 

 lunate, the elytra abruptly grooved and the pygidium vertical, 

 scarcely wider than long and coarsely punctate. The type species 

 is as follows : 



Parasolaria lobata n. sp. — Oblong-suboval, deep black, polished and glabrous 

 throughout; beak (o 71 ) feebly, evenly arcuate, not tapering, distinctly shorter 

 than the prothorax and somewhat strongly punctured, or ( 9 ) longer and even 

 somewhat thicker, but more tapering distally, more arcuate and a fourth longer 

 than the head and prothorax, finely and sparsely punctate, the antennae piceous, 

 near basal third; prothorax two-fifths to one-half wider than long, the sides, 

 feebly converging and nearly straight, rapidly rounding beyond two-thirds, 

 oblique and feebly sinuate to the apex, which is prominently lobed medially, 

 less so in the female and much more than half as wide as the base; punctures 

 strong but well separated, gradually smaller and sparser medially, with rather 

 wide smooth median line; elytra oval, nearly one-half (cf ), but only a fifth ( 9 ), 

 longer than wide, evidently wider than the prothorax and two-thirds (o 71 ) to 

 one-half (9) longer; grooves deep, punctate, a third as wide as the intervals, 

 which become slightly carinulate laterally, the interstitial punctulation uniserial 

 and infinitesimal; first ventral suture wholly obsolete throughout; male ventral 

 characters not evident. Length 2.7-3.0 mm.; width 1.3-1.5 mm. Brazil 

 (Chapada — forest). Two specimens. 



If the two specimens representing this species are correctly 

 assigned, there is a rather unusual amount of sexual divergence, but 

 on the whole, partaking of the nature of these differences in Cono- 

 proctus and others, where the male is notably larger than' the female; 

 but here, the female beak is distinctly longer than that of the male; 

 it is somewhat flattened distally in both sexes and very much 

 broader than in Solaria. 



Solaria Chmp. 



In this genus the body is more broadly oblong-oval, with more 

 developed prothorax, small antennal club, more gradually formed 

 and rounded thoracic lobe, smaller and equilatero-triangular scu- 

 tellum, smaller pygidium and distinctly denticulate femora. There 

 seems to be but little sexual difference, the beak in the male smaller
