humeris rude granulato-punctatis, dorso punctato ; corpore 
infra griseo plus minus flavido-variegato, sternis antice et 
postice lateribusque abdominis pallido-pilosis ; segmento

Synixais, nov. gen. 
(Niphoninse.) 
Oculi subdivisi. Metasternum mediocre, haud breve. 
Corpus undique pilosum. Tarsi postici tibiis haud lon- 
giores. Oculi minute granulati. Frons plana, paullum 
transversa, lata. Lobi inferiores oculorum subquadrati, 
genis multo (fere duplo) breviores. Antennae corpore bre- 
viores, infra usque a basi longe ciliatae; scapus obconicus vel 
elongato-pyriformis, medium prothoracis attingens; arti- 
culus Sms scapo vix longior, apice intus leviter incrassatus; 
articulus 4:us 3:o tertia parte brevior, apice paullulum 
incrassatus; articuli 5-11 breves, 3:o et 4:o simul sumtis 
breviores; ll:us valde curvatus apice spiniformis. Pro¬ 
thorax subquadratus, convexus, omnino inermis; sulcus
