Brazilian Baring 493 



Anterior femora simple, never even denticulate beneath, the others also mutic.3 



3 — Body glabrous above 4 



Body squamose, exactly and rectilinearly parallel, the prothorax subquadrate; 

 antennal scape long; prosternum rather short, flat, truncate behind 5 



4 — Antennal scape very short. Body parallel, coarsely sculptured; beak short, 

 somewhat thick, cylindric and arcuate; antennae behind the middle, moder- 

 ately long, the club small; prosternum rather short, flat, moderately sepa- 

 rating the coxae, the entire hind margin truncate; prothorax not tubulate, 

 the basal lobe subobsolete; scutellum small; elytra deeply grooved; legs 

 short, the claws free. [Type P. rubricollis nov.] Paralichnus 



Antennal scape long. Body parallel but with conical prothorax, feebly sculptured; 

 beak short or moderate, more or less thick; antennae beyond the middle, 

 more or less short, the club narrowly oval as a rule; prosternum unmodified, 

 the coxae almost contiguous; hind margin feebly arcuate at the middle; 

 scutellum moderate; elytra very feebly or obsoletely striate; legs long and 

 very slender, the claws free. [Type M. talpa Gyll.] Madopterus 



5 — Beak slender, nearly straight, cylindric, not tapering and not separated from 

 the head by an impression; antennae submedial, slender, the first funicular 

 joint as long as the next three, the club small, oval; prosternum narrowly 

 separating the coxae, its surface tumid at the middle behind them; prothorax 

 subquadrate, not tubulate, the basal lobe small and almost obsolete; elytra 

 coarsely striate; pygidium notably short; tarsi rather inflated, the claws 

 connate. [Type S. lemniscatus Boh.] Strongylotes 



Beak not so slender, perfectly straight and less vertical, feebly tapering from 

 base to apex; antennae nearly similar; prosternum separating the coxae by 

 fully half their width, flat and not at all tumid medially posteriad; prothorax 

 sometimes very briefly and feebly tubulate at apex, transversely truncate at 

 base and somewhat conspicuously inflated at the sides beyond the middle; 

 elytra nearly similar, the pygidium larger, twice as wide as long and circularly 

 rounded; anterior tarsi more dilated, the claws free but close. [Type A T . 

 amplitarsis nov.] Neobaridia 



6 — Body very slender, parallel and linear, squamose above; beak short, slender, 

 cylindric and slightly arcuate, not separated by an impression; antennae 

 somewhat behind the middle, the first funicular joint as long as the next 

 three, the club small, narrowly oval; prosternum flat, narrowly separating 

 the coxae; prothorax elongate, truncate at apex and with small and feeble 

 basal lobe; elytra nearly as in Strongylotes: tarsi moderate, the claws free. 

 [Type C. cylindrica nov.] Camopis 



Body rather broad, oblong, parallel, nearly glabrous above; beak straight, longer, 

 more slender and dorsally bisulcate basally (9), less slender and simply 

 cylindric (o 71 ); antennae submedial, slender, the first two funicular joints 

 elongate, the club small and narrowly oval; prosternum evenly and feebly 

 convex, separating the coxae by more than half their width, truncate behind; 

 prothorax non-tubulate, with very small basal lobe; elytra strongly striate; 

 tarsi rather slender, the claws free. [Type C. rectirostris nov.]. . .Canopinus 



Canopinus seems at first to be very inharmonious among the 

 other genera, because of its much more abbreviated form of body, 

 but its structural characters place it in the present tribe, where it 

 may perhaps be compared, in some features at least, with Parallel- 

 osomus. Sexual divergencies appear to be very slight in most of 

 the genera, though very evident in the beak of Canopinus.
