This species differs from those of Florissant by the more 
slender wings and narrower costal area. The holotype, No. 
3639 ab in the Museum of Comparative Zoology, is the best 
preserved fossil snake-fly which has been found, apart from 
those in amber. The members of the Raphidiodea are ex- 
ceedingly rare in the Florissant shales, and the presence of 
even one in the relatively small Creede collection at hand is 
another indication of the biotic differences represented. 
Like the Florissant Raphidiodea, this Creede species belongs 
to a genus now restricted to the Old World. 3

The single fossil wing sent to me for identification proves 
to represent a species of Reticulitermes new to science. Five 
fossil species of this genus are already known — four from 
Baltic amber and one from the Miocene shale of Florissant, 
Colorado. Reticulitermes is confined to the temperate re- 
gions of the world. A living species (R. tibialis Banks) 
occurs in localities in Colorado, but nowhere in the state at 
an elevation of over 7,000 feet. The wing of tibialis is larger 
than in this fossil.

Raphidiodea is contained in my revision of the Nearctic species (Proc. 
Amer. Acad. Arts Sci., 70: 89-157, 1936).
