 Tt/pe. — Gonibreynintus cumiwiii, Newport. 



The known charaeters of tliis genus are so remarkable that others 

 equally interesting are to be expected from an examination of the 

 mouth parts. 



ORYIDtE, new family. 



Antennae attenuate or subfiliform; frontal lamina coalesced or dis- 

 tinct; cephalic lamina concealing the prehensors; prebasal lamina ob- 

 solete; basal lamina broad; labium entirely coalesced; mandibles with 

 several pectinate Limelke; no dentate lamellne; labial sternum entire,

 verse indefinite areas; last sternum broad; the pleur;e not inflated,
