elevatis vix conspicuis. Corpus subtus convexum pedesque den- 
sius et sequaliter griseo-pubescentia, femoribus posticis segmen-

14. Plo ccederus (J. Thoms.) pronus: oblongus, supra niger, sub¬ 
tus piceus, epistome, palpis antennisque fusco-ferrugineis, tho¬ 
race supra transversim plicato, lateribus unispinosis; elytris 
tenuissime griseo-sericeis, apice bispinosis, antennarum articulis 
3—5 aculeatis. Long. 19, lat. 5| millim. q 71 . 
Caput latitudine fere longius, vertice tenuiter granulato, 
fronte inter oculos distincte carinata, antice declivi et foveo-

corpore duplo longiores, apicem versus attenuatse, scapo sub- 
scabro, articulis 3—5 apice nodosis distinctiusque spinosis, 
6—10 denticulatim productis. Thorax latitudine baseos vix 
brevior, antice truncatus, basi medio leviter rotundato-lobatus, 
supra transversim, crebre at minus regulariter, plicato-rugosus, 
lateribus spina valida acuta armatis. Scutellum breve, apice 
subrotundatum, medio impressum. Elytra linearia, basi tho- 
racis fere duplo latiora latitudineque sua triplo longiora, apice 
conjunctim rotundata ibique spinulis duabus sat distinctis ar- 
mata, dorso sat convexa, obsolete coriacea, sequaliter griseo- 
sericea. Corpus subtus modice convexum, subcoriaceum, tenu¬ 
issime flavo-griseo-pubescens. Pedes longiusculi, subsimplices, 
coriacei, griseo-pilosi, picei, femoribus basi et nonnumquam ti- 
biis tarsisque plus minusve rufescentibus. 
15. Ploccederus frenatus: oblongus, niger, supra tenuissime, sub¬ 
tus densius giiseo-pubescens, antennis fusco-ferrugineis, articulis 
3—6 apice valide aculeatis; thorace supra irregulariter plicato, 
lateribus spinosis, antice callosis; elytris convexis, apice bispi¬ 
nosis. Long. 33—37, lat. 11—12 millim. 
O 71 PL prono in plurimis simillimus; praeter magnitudinem 
insigniorem, differt tantum antennis corpore triplo longioribus, 
apicem versus gracillimis, articulis 3—6 coriaceis, punctis spar- 
sis impressis, 7—10 apice indistincte modo angulatis; thorace 
supra temere plicato, plicis partim gyriformibus, lateribus medio 
spina acutissima armatis atque ad marginem apicis distinctius 
callosis; corpore subtus densius villoso pedibusque indeterminate
