5 — Apex of the prothorax broadly arcuate medially, the sides coarsely 

 crenulate. Cuba. \l^y'^Q. Nosoderma duponcheli ^o\.~\. 



* Meralius 



Apex of the prothorax broadly emarginate, approximately bituber- 

 culose on the disk at the middle, with the sides coarsely crenulate ; 

 elytra cristate and tuberculose somewhat as in Nosoderma ; pro- 

 thorax short, smooth and but slightly uneven on the disk, the 

 elytra elongate; scutellum circular, tumescent, densely scaly and 

 conspicuous; hind coxa; much more approximate than usual. 

 Brazil. [Type iV". annul atipes w. sp.] * Noserinus 



Apex of the prothorax broadly emarginate, the sides granulose or 

 finely tuberculate, never coarsely crenulate. Mexico 6 



6 — Mentum very small, obliquely narrov^ed at apex, exposing the 



entire ligula and the maxillas; last three joints of the maxillary 

 palpi subequal in length ; elytra rounded at tip, with some large 

 isolated tubercles on and above the apical declivity, none of which 

 is marginal. \^y^Q Eurychora incequalis Say] — * Nosoderma 



Mentum small, trapezoidal anteriorly, concealing the base of the 

 ligula; last joint of the maxillary palpi large, almost as long as 

 the two preceding combined ; middle coxte less widely separated ; 

 elytra subconical at tip between the two large subapical marginal 

 tuberosities. [Type N. squalidus n. sp.] * Noserodes 



Mentum small ; elytra rounded behind, without inequalities, the entire 

 surface of the body devoid of tubercles or ridges and merely finely 

 and equally granulated ; prothorax elongate, suboval ; antennas 

 submoniliform, the eleventh joint enclosed b}^ the tenth, which is 

 very large and truncate at tip. [Type Nosoderma cequalis 

 Champ.] *Verodes 



7 — Antennae free, the last three joints wider, forming a loose club, 



the sternal grooves wholly obsolete ; tarsi not grooved beneath 

 except the last joint, which is feebly impressed; mentum small, 

 transverse as usual, broadly rounded at apex, exposing the max- 

 illiE and ligula, the latter short, broad, tumid and densely chitinous ; 

 last three joints of the maxillary palpi subequal in length; elytra 

 ridged, strongly tuberculose at and near the apex. Nearctic 

 regions. [Type Boletophagus obcordatus Kirby] Phellopsis 



These genera, as indicated by the asterisks, are nearly all 

 foreign to our own territory. Sesaspis (n. gen.) is founded 

 upon a very remarkable species, which is well described by 

 Solier, but which was not rediscovered by the workers on the 

 " Biologia." Meralius {yv. gen.) represents a type peculiar to 

 the Caribbean fauna, and Verodes (n. gen.) is founded upon a 

 peculiar species recently made known by Mr. Champion in the 

 epoch-making publication referred to. Noserinus (n. gen.) is
