et inter carinas laeves. Maxillae angustae, leviter curvatae, apice 

 obtusae, inermes. Frons acute bisulcata. Thorax valde trans- 

 versus, lateribus fortiter dentatus , lobo basali sat producto, 

 margine inter lobum et dentem lateralem subsinuato. Ely- 

 tra relative brevia et angusta, humeri valde dentati, inter- 

 stitio 7nio alte carinato prope basin intra dentem humera- 

 lem iucurvato. Tarsi , praecipue articulo 5to cum unguiculis 

 elongati: tibiae intermediae extus unispinosae. Episterna me- 

 tathoracica brevia subquadrata. Abdominis segmenta 3 — 5 

 basi transversim sulculata, 2 — 6 foveolata. 



The obtuse aud wholly unarmed apex of the maxillae and 

 dentate sides of the thorax bring this genus into the neigh- 

 bourhood of Haplogaster and allies , but it has certainly a 

 close affinity with Tamiolobus , with which genus it is con- 

 nected by several Tropical African species having, like 

 Tceniolobus, the maxillas produced at their inner apex, but 

 with the deeply bisulcate forehead and facies of Aulacillus. 

 In the rather long and robust claw-joints and claws it 

 indicates also an affinity with the very different-looking genus 

 Ochyropus.
