 large, the propygidium well developed; prosternum deeply canalate 33 



21 — Prosternum flat or but feebly and indefinitely impressed 22 



Prosternum canalate, very shallowly in Zathanius and Euzathanius, and some- 

 what so in Dalcesia; body small in size, much larger in some species of 

 Baptobaris 28 



22 — Body large or very large in size, comprising some of the largest of the sub- 

 family; scutellum free as usual 23 



Body small or very moderate in size 27 



23 — Posterior end of the prosternum proper, that is, at the intercoxal suture, 

 prominent or apparently free 24 



Posterior end not prominent or free, the suture fine 25 



24 — Beak cylindric, moderately slender and partially almost smooth; antenna? 

 not very thick, the club small, barely longer than wide; body subrhombic- 

 oval; scutellum with three transverse excavations; elytral striae fine, very 

 coarsely and catenulately foveate. [Type M. resplendens nov.]. Megalobaris 



Beak short, thick and strongly punctured throughout; antennae (o 71 ) short, very 

 thick, subcylindric, the funicular joints close and very transverse, the club 

 small, almost globular; body parallel; scutellum quadrate-oval, smooth; 

 elytral striae coarse, with relatively smaller catenulate punctures; propy- 

 gidium well developed in the female. [Type D. oblongus nov.] . . Dissopygus 



25 — Antennal club large, oval, as long as the five or six preceding joints. Body 

 oblong-oval, with somewhat prominent humeri; beak rather long, arcuate; 

 scutellum subquadrate; elytral striae moderate, with relatively moderate 

 catenulate foveae; propygidium somewhat visible in the female. [Type 5. 

 regalis nov.] Sclerobaris 



Antennal club small, conoidal 26 



26 — Elytra not exarate distally and with moderate subapical umbones, moderately 

 undulated, the striae having conspicuous elongate-oval catenulate foveae; 

 beak cylindric, moderate in length, smoother distally; scutellum subquad- 

 rate-oval or elongate, variously impressed; pygidium very prominently, 

 longitudinally tumid in the male. [Type Baridius metallicus Boh.] 



Stereobaris 



Elytra conspicuously and deeply undulated, coarsely exarate at apex and with 

 very prominent umbones, the striae finely and smoothly grooved, elongate- 

 foveate at base; pygidium flat and finely carinate; scutellum transversely 

 quadrate; beak very short, thick and strongly, densely punctate. [Type 

 Baris monstrosa Germ.] Cymatobaris 



27 — Beak thick, separated from the head by a fine abrupt sulcus and about as 

 long as the prothorax; basal segment of the antennal club half the mass and 

 glabrous; body stout, oblong, herissate with stiff bristles; claw-joint un- 

 usually long and with very distinct basal node. [Type G. hystrix nov.] 



Glyptobaridia 



Beak thick, always shorter than the prothorax, separated from the head by a 

 more or less sharply marked reentrant angle; basal segment of the antennal 

 dub large and glabrous; body oblong-oval, never with more than slender 

 inclined squamules, which are evenly distributed in typical forms, but
