Genus Gnathomerium Ribaut. 

 GriathoDierium nmbraticnm (McNeill). 



Syn. Gnathomerium americanum Ribaut. 

 Locality. — Manitou, Colorado. 



This seems to be a southern species, occurring widely and abund- 

 antly throughout the Southern States. In favourable seasons it may be 

 found to be not rare in the present region, as Bollman reports it as com-

Subfamily Linoteniinre. 

 Genus Linotenia Koch. 

 Linotenia chiojiophila (Wood). 



Localities. — Devil's Lake and AslilanJ, Wis. 



Many specimens were taken at the former locality under leaves and 

 stones about the margin of the lake. This species is boreal, being 

 abundant, comparatively, in Alaska and adjacent islands. It was first

 North. It is very close to Linotenia acinnitiata (Leacii) of Europe, and 

 may have to be merged with it.

Localities. — Mongona, Boone, De^Vitt and Marshal! town, Iowa ;

Very much the commonest Linotenia in the Northern United States,
