Caput verticale, tlioraci profunde insertum, supra oculos profun- 

 dius areuatim impressum, desuper haud conspicuum. OcuU ob- 



" longi, intus leviter sinuati. Antenncs ad angulum oculorum 

 infero-interiorem sitae, corpore dimidio breviores, 12-articu- 

 latse; articulus 1"" subglobosus, 2"° quintuple minor, brevissi- 

 mus ; 3"^ oblongus, compressus, duobus prsecedentibus longitu- 

 dine sequalis; 4-6*""" longitudine decrescentes, latitudine in- 

 crescentes, compressi ; 6*"^ subtriangularis ; 7-10°""" latissimi, 

 valde compressi, cum 11"° et 12"° clavam 5-7-articulatam spa- 

 tuliformem constituentes ; 7-9^""" subtriangulares, latere ex- 

 terno emarginato, angulo interiore rotundato ; 12""' 11""° fere 

 absconditus§, arete cum eo conjunctus, extus late rotundatus. 

 Ziabrum oblongum, apice obtuse rotundatum, subito deflexum, 

 utrinque hirtum. Palpi maxillares articulis ultimis duobus 

 crassioribus, ultimo apice truncate. Mandihulw obtuse biden- 

 tatse. Thorax cylindricus, antice subito fornicatus, plus minus 

 angustatus, genas arete complectens, post oculos utrinque 

 sinuatus, longior quam latior, lateribus subrectis. Presternum 

 antice subrectum, lateribus oblique deflexis ; postice utrinque 

 late sinuatum, lobo posteriore angusto. Metasternum angus- 

 tum, antice 3-sinuatum angulis truncatis ; lateribus subrectis, 

 angulis posterioribus subacute productis. Antepectoris pro- 

 cessus antero-lateralis scaleno-triangularis, apice ab humero 

 suam ipsius longitudinem remote. Scutellum parvum, semi- 

 ellipticum. JElytra thorace latiora, oblonga, convexa, lateri- 

 bus parallelis, lentius ad apicem conjunctim clausa, angulis 

 anticis obtusis aut nullis. Pedes robusti, tibiis extus apice 

 dilatatis, canaliculatis ; tarsorum articulis subsequalibus ; un- 

 guium appendiculis variis. 



Type of the genus, Oorynodes compressicomis, Fab. 



I have some ^ffidence in proposing this genus in its present 



§ For the sake of convenience we shall for the future regard the antennae as 

 ll-jointed, reckoning the two last joints as one.
