STRONGYLIUM. 
S. terminatum Say. S. crenatum Makl. 
Crenatum is a rare and beautiful species. I have beaten speci- 
mens from the dead branches of Haw tree, June 22, 1900, and June 
26, I9Ol.

This was once a very rich locality for Mycetochara. I found 
them in numbers on the trunks of dead trees. They are brittle 
insects, breaking easily when handled. To get them perfect, they 
should be picked up gently, not an easy thing to do, as they run so 
rapidly and are not easily caught. They feed on fungus. I have 
a species which I believe to be new and for which I propose the 
name: 
Mycetochara horni n. sp. 
Color testaceus, head and thorax darker. Legs paler. Anterior 
coxz very large and approximate. Elytra slightly wider behind
