Plate 2 shows a lateral and a dorsal view of the allo- 
type, male, of Notiothauma reedi, McL., from photo- 
graphs made by Professor Davis, of the Department 
of Botany, M. A. C. In these photographs the Blat- 
toid appearance of Notiothauma is well shown. Note 
particularly the flat incumbent wings, which are unlike 
those of any other living Mecopteron, in this respect. 
The figures of Notiothauma, with wings outstretched, 
do not give a correct idea of the remarkable appear- 
ance of this peculiar insect, as may be seen by com- 
paring them with the photographs here given. The 
photographs are larger than “life size,” in order to 
show the intricate venation.
