I have seen no specimens of this insect, but include here 
a drawing of the fore wing made from the type (<?, Rio de 
Janeiro, Brazil) by Mr. D. E. Kimmins, of the British 
Museum (Natural History). Photographs of the wings

wings of type ( $ ) in the Museum of Comparative Zoology. 
of prestoni are reproduced in Professor Da Costa Lima’s 
Insectos do Brasil , tome 4 (1943), figures 54 and 55. As 
shown in figure 1, there are seven short cross-veins in the 
subcostal space, and five main branches of the radial sec- 
tor (not including MA). The posterior branch of MP is 
not anastomosed with CuA. Mr. Kimmins also kindly 
sent me a drawing of the terminal abdominal structures, 
which closely resemble those of N. americanus (Carpen- 
ter, 1940, fig. 74).
