fore wing described under the name thevenini. This statement is 
not correct as thevenini has an unusual type of archedictyon, with 
elongate cells, and it also has a deeply concave anterior margin. 
Hind wing: probable length 80 mm, width 18 mm. Anterior 
margin slightly convex proximally and slightly concave just beyond 
the midwing; posterior margin convex at the end of 2A. Apical 
part of wing narrow and elongate. R-rs area broad; Rs originating 
well before mid-wing, with about five branches. MP and CuA 
giving rise to one irregular branch, probably secondarily formed 
by the archedictyon. Cubital area very narrow; course of CuP 
irregular. Anal area large with side branches^ sometimes forked. 
S. arnaudi differs from all other species by the irregular course 
of MP and CuP (which, of course, may be an individual trait 
only). It is similar to S. oustaleti in having a large anal area with 
1 A forked.

Mdcrodictya klehsi Meunier, 1908: 154; Meunier, 1908: 38, fig. 2; Meunier, 
1908: 135, pi. 2, fig. 1. 
Stenodictya klehsi Handlirsch, 1919: 6, fig. 7. 
This species was based by Meunier on a complete hind wing. 
Unfortunately, I could not find the type specimen in the collection 
at the Institut. The accompanying figure was made from a very 
good photograph which Dr. Carpenter made in 1938 and in which 
all features are clearly visible. 
Hind wing: length 72 mm, width 21 mm. Anterior margin slightly 
convex proximally, then straight. Posterior margin with only a 
small convex curvature at iA. Apical part short and broadly 
rounded. Rs originating shortly before mid-wing, with 5 branches. 
Anal area large, with 4 veins, iA forking. Archedictyon with a 
tendency to form additional twigs. 
S. klehsi has the broadest hind wing of all related species, especially 
in the apical part. Its outline resembles that of laurenticcuxi sp. nov. 
and parisiana sp. nov. 
Stenodictya parisiana sp. nov.

This species is based on a complete hind wing in the Institut 
collection. Its position is remote from the other species by the more 
advanced modification of the archedictyon into cross veins, which
