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



crenulate. Cuba. [TypQ N'osodci-ina dupofic/ieli So\.'\. 



* 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 Nosodernia ; pro- 

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

 elytra elongate; scutellum circular, tumescent, densely scaly and 

 conspicuous; hind coxae much more approximate than usual. 

 Brazil. [Type A'^. anmdatipes n. sp.] * Noserinus 



Apex of the prothorax broadly emarginate, the sides granulose or 

 finely tuberculate, never coarsely crenulate. Mexico 6 



6 — Mentum very small, obliquely narrowed at apex, exposing the 



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

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

 isolated tubercles on and above the apical declivit}', none of which 

 is marginal. [T^y^e. JEziryckora 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 coxaj less widely separated; 

 elytra subconical at tip between the two large subapical marginal 

 tuberosities. [T3'pe JV. 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 ; antennie 

 submoniliform, the eleventh joint enclosed by the tenth, which is 

 very large and truncate at tip. [Type Nosoderma (xqualis 

 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- 

 illae 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. Sesaspts (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." Afcralius (n. gen.) represents a t3^pe 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. Noser/nns (n. gen.) is
