This species was erected by Brongniart on specimen 21-9, a 
hind wing lacking the base and most of the posterior margin. The 
following account was completed after exposing additional features 
following the removal of substantial matrix. 
Hind wing: length 65 mm; preserved width 26.5 mm. Anterior 
margin straight, strongly curved towards apex; apex broadly round- 
ed. Sc terminating at the end of the second third of the length of 
the wing on R ; Rs with 3 branches, first of them forked ; MA 
slightly concave soon after its origin with a small fork at the end; 
MP probably with 2 branches extending anteriorly; CuA slightly 
concave in the first third of its course, CuP twice forked; anal 
area with 6 widely spaced branches. Cross venation dense, some- 
times the cross veins connected, forming a network in the rs area. 
Strong, regular cross veins present in anal area. Long hairs occur 
in two clusters in the subcostal and sc-r areas, arising in circular, 
cuticular thickenings in cua-cup area and bordering the posterior 
margin. Small rounded cuticular thickenings forming rows between 
some branches. 
Breyeria lachlani (Brongniart) differs from boulei in its denser 
and more reticulated cross venation and in the widely spaced anal- 
veins, resembling those of the fore wing. It is similar to many 
other species, such as delruei, vrankeni, rappi t etc.

Breyeria ( Borrea ) lachlani Laurentiaux and F. Laurentiaux-Vieira, 1951: 
590. 
This species was erected by Meunier upon a nearly complete 
hind wing. In comparison with all other hind wings of the genus, 
boulei does not have a very broad anal area and consequently it lacks 
the typical triangular shape. 
Hind wing: length 59 mm, width 25 mm, broadest at about 
the first third of the wing length. Anterior margin, strongly 
curved towards the apex. Apex directed posteriorly, slightly pointed. 
Posterior margin as a whole convex, slightly concave in the cua-cup
