of lachlani. After having removed much matrix on the specimen 
of bonlei I was able to see more details of its venation, including 
some which are specific differences and which eliminate the possi- 
bility of the synonymy with lachlani. 
Specimen 21-5, designated by Handlirsch (1906, p. 97) as 
Megaptiloides brodiei , is too fragmentary for definite classification. 
It shows dense cross veins, richly anastomosed and tending to form 
short intercalary sectors. The hairs along the margin are absent. 
Handlirsch's classification of brodiei into a separate genus is prob- 
ably justified. 
The following account is based mostly on the details already 
published by Laurentiaux, Laurentiaux and Laurentiaux-Vieira, 
Carpenter and Kukalova. 
Wings subequal, hind wing being somewhat shorter and broader. 
Hind wing sometimes very broad in the anal third and often of 
triangular shape. Postcostal area triangular, with several short 
branches. Sc terminating far before the apex, on R ; Rs with 3-6 
branches, the first of them often forked. Branches of M, Cu and 
the anals are curved sharply toward the posterior margin. MP 
with 1-5 broad forks; cua-cup area often markedly broad. CuP 
with 1-2 forks, seldom simple. Anal area either with a series of 
about 5 simple branches or with a series of simple long forks. 
Cross veins fine, irregular, rather dense, sometimes connected by 
irregular anastomoses. In the anal area, there are often present 
stronger and straighter cross veins (in addition to the finer ones) 
tending to be arranged in regular rows. Circular cuticular thicken- 
ings are often present in rows in the areas of m, rs and cu. 
Breyeria Borre differs from Stobbsia Handlirsch by having Sc 
ending on R and by the branches of M, Cu and the anals abruptly 
curving toward the posterior margin.
