ERIRHINUS Schonherr. 



This is an Old World type, the species from North America formerly 

 placed here being now regarded as distinct. It has been recognized as fossil 

 by Oustalet in a single species at Aix, and one has been indicated from amber 

 by Motschulsky, under the name Erirhinoides. 



The species here included in this genus is so placed onlv as typical of 

 the Erirhinini. Its much briefer rostrum, as well as the exceptional size of 

 the head, forbids its being classed here in any strict sense; Init as I can find 

 no genus to which it appears nearly allied among our Erirhinini (to wliicli 

 from its general characters it ap])ears to Ix-long, although tlic abdominal 

 segments are equal in length), it is provisionally placed here. 



Eriehinus dormitus.
