 Legs same color as those of /. johnsoni." Several sketches accom- 

 pany the notes, making the identity even more positive. 



The small series of this species examined by us is sufficient to show 

 that its relationship is very close to /. deropeltiformis, the males also 

 looking like pale editions of /. johnsoni, from which, however, the 

 female can immediately be separated by the shape of the tegmina. 

 The only specimen we have examined with date was taken in April. 

 Specimens examined. — Six; five males, one female: 

 Jacksonville, Fla. Two males. (U. S. N. M. and Bruner Collection.) 

 St. Augustine, Fla. One male. (Morse Collection.)
