Brazilian Baring 497 



and broadly rounded basal median lobe, the scutellum small, free, 

 quadrate and slightly impressed, the elytra strongly striate and the 

 pygidium small, flat, densely sculptured and semicircular. . The 

 legs are short and normal, the femora not inflated, the tarsi rather 

 narrow and the claws arcuate, free and moderate in size. The type 

 is the following: 



Paralichnus rubricollis n. sp. — Not very slender, parallel, convex and shining, 

 deep black throughout, with bright rufous prothorax above and beneath; beak 

 evenly arcuate, feebly tapering, rather finely but strongly, loosely punctate and 

 as long as the prothorax, the antennae obscure rufous; prothorax a fourth wider 

 than long, the sides parallel and straight basally, gradually evenly rounding 

 beyond the middle to the truncate apex, which is half as wide as the base; punc- 

 tures deep and conspicuous but rather widely separated even at the sides; median 

 smooth line flat and abbreviated; elytra not quite two and one-half times as long 

 as wide, with parallel straight sides, gradually arcuate toward the not very 

 obtuse apex, barely visibly wider than the prothorax and two and three-fourths 

 times as long, the humeral swelling feeble and notably small; striae very coarse, 

 approximately and strongly punctate, very coarse though sharply groove-like at 

 apex; intervals three times as wide as the striae, with uneven series of very small 

 and widely spaced punctures; surface feebly declivous at base and without sub- 

 apical umbones; first abdominal suture very fine and subobsolete, the others 

 coarse and deep, reflexed at the sides. Length 6.6-7.0 mm.; width 2.0-2.35 mm. 

 Paraguay. Rolle and Drake. Two specimens. 



No trace of any modifications significient of sex can be discovered 

 in either of the specimens at hand. 



Madopterus Schon. 



In this well known genus the body is glabrous, polished, cylindric, 

 with conical prothorax and short and transverse, inferiorly arcuate 

 and distinctly oblique pygidium. The beak is moderately slender 

 to rather thick, short or moderate in length, evenly cylindric, feebly 

 arcuate and not separated from the head by an impression. An- 

 tennae well beyond the middle, with long scape, almost attaining the 

 eye, the first funicular joint notably thick and rather longer than 

 the next two, and the club not abrupt, large, ovoidal, thick and 

 conically pointed. Prosternum flat or feebly convex, raised and 

 prominent along the middle behind the coxae, which are subcon- 

 tiguous, the truncate hind margin very obsoletely prominent at the 

 middle. The prothorax is not tubulate at apex, the basal margin 

 very gradually and feebly subcuspid at the middle and the scutellum 

 free, quadrate and feebly impressed. The elytra are very finely 

 and more or less obsoletely striate, not impressed at base, but 

 strongly and irregularly exarate at apex, the third and ninth inter- 

 vals becoming prominent subapically, united near the apex and 

 continued to the margin by a single elevation. The legs are long, 

 slender and simple, the tarsi rather narrow, the anterior moderately
