eyes. One antenna (A) is preserved for a length of 6.5 mm but 
quite clearly this is not the complete antenna, since it ends abruptly 
in the matrix. The other antenna is preserved only for a short 
distance from the head. It is probable that the antennae were at 
least as long as the fore wings. 
The few body parts preserved in this specimen are consistent 
with those known in the Caloneurodea. 
Order Blattaria 
Two specimens of roaches were collected by Dr. Mamay in the 
Madera formation. One of these consists of an isolated fore wing 
and the other of a nearly complete insect, lacking the two fore 
wings. Because of the difficulty of making taxonomic assignments 
of Paleozoic roaches, I am not describing these specimens formally. 
The second specimen, however, is of interest because it shows
