432 Memoirs on the Coleoptera 



15 — Tibiae angulate and more or less prominent externally at base; presternum 

 evenly and deeply canalate, the posterior lobe broad but short; body oblong- 

 oval, strongly, densely sculptured and with coarsely grooved elytra, glabrous; 

 beak rather short and thick; prothorax with short and gradually formed 

 basal lobe, the scutellum free, rounded-subquadrate; pygidium small, simple; 

 tarsi small. [Type A. tibialis nov.] Anagivenius 



Tibiae simple, not angulate externally 16 



16 — Beak short, oval, scarcely over twice as long as wide and very thick; antenna? 

 short, the first segment of the club polished; body stout, oval, very coarsely, 

 densely sculptured, the elytral grooves broad and deep; pygidium small, 

 simple; scutellum free, transversely subquadrate; presternum very shallowly 

 canaliculate, the lobe very short; legs short, the tarsi slender. [Type P. 

 ovirostris nov.] Prantisus 



Beak of normal form, moderate in length; body narrower, more or less small in 

 size; pygidium small, simple 17 



17 — Presternum with a posteriorly bifurcate excavation, the dividing projection 

 sometimes obsolete, the posterior lobe prominent, extending well over the 

 mesosternum, but not so closely continuous as in the Madarini, and often 

 medially excavated; body small, sometimes notably minute in size, always 

 rather strongly, sometimes very densely punctured, the scutellum small and 

 rounded as a rule, more or less closely fitted; tarsi short and slender; first 

 abdominal suture obliterated medially. [Type H. carbo Kirsch] 



Heterosternus 



Presternum with apparently simple canal; body narrower and more elongate, 

 less strongly sculptured, especially the abdomen, where the first suture, 

 though fine, is entire; beak somewhat long and slender; prothorax distinctly 

 more tubulate at apex; tarsi much longer, the claws widely divergent, though 

 in close contact at the extreme base. [Type N. cylindroides nov.] 



Neogivenius 



Presternum with a simple and more parallel canal 18 



18 — Body very small, slender and cylindric, densely sculptured and glabrous; 

 prosternal lobe short; scutellum free, rounded; elytra moderately grooved, 

 the intervals with imbricate sculpture; pygidium transversely prominent 

 near the apex; legs short, slender, the tarsi small, with very small claws; 

 antennal club rather small, elongate-oval and moderately pubescent. [Type 

 A. cylindrica nov.] Anathaniops 



Body not cylindric; scutellum free 19 



19 — Beak thick; antennal club narrow, elongate, subequally divided by the 

 sutures and fully as long as the preceding six joints; body glabrous; pro- 

 thorax not evidently tubulate at apex, the small basal lobe emarginate; 

 scutellum obtriangular, impressed; elytra with basally coarser, catenulately 

 punctate grooves; pygidium very feebly, transversely swollen near the base; 

 presternum broadly and shallowly canalate, the lobe short; legs simple, the 

 tarsi slender, with very small claws. [Type L. santaremica nov.]. .Lupulina 



Beak moderate, arcuate, the antennal club large, evenly oval, abrupt and as long 

 as the preceding six joints; body very small in size, glabrous and shining, 

 less strongly sculptured; prothorax not evidently tubulate, the small feeble 

 basal lobe very abruptly and deeply sinuate; scutellum small, free, sub- 

 quadrate and narrowly canaliculate; elytra smoothly grooved; pygidium 

 small, simple; prosternum very feebly, longitudinally impressed, the lobe 

 narrow, extending to the mesocoxal tangent; legs short, the tarsi very 

 slender. [Type B. clavigera nov.] Brachylinoma 



Beak moderate, the antennal club small, stout and evenly oval, with much larger 

 basal segment; body very small and with distinct setiform squamules; 

 prothorax scarcely at all tubulate at apex and with small rounded basal
