A Fossil Raphidia (Neur., Planip.). 
By T. D. A. CocKEerELL, Boulder, Colorado. 
A well-preserved anterior wing of Raphidia was found by my 
wife in the Miocene shales of Florissant, Colorado, at Station 
23. It is about 12.75 mm. long and 3.75 broad. On comparing 
it with the type of R. exhumata CkIl., I find that it corresponds 
very closely in appearance and structure, but in Rohwer’s ta- 
ble (Amer. Journ. Science, xxviii, 534) it runs to R. mortua 
Roh., from which it differs by the larger size, darker venation, 
the greater number (nine) of cross-veins in the costal area, 
subcosta joining costa much less than length of stigma from 
stigma, and some other details. It differs from R. exhumata 
principally as follows: 
(a.) Only two cells on costa beyond stigma (three in e+- 
humata.) 
(b.) Second cross-vein connecting radial sector with media 
a considerable distance basad of forking of sector, as in R. 
mortua (jointing base of fork in exhumata). 
R. txhumata 
TYPE- 
(c.) Fifth branch of radius forked at end, though fourth 
is simple (both simple in exrhumata). 
Thus the new fossil seems intermediate between R. exhu- 
mata and R. mortua; it may be known as FR. exhumata var. a,
