ally not present and that he omitted one. The one which he omitted 
is located between CuP and iA; the one which he shows most distally 
is, I believe, only an irregularity in the rock, not part of the wing; 
its appearance is very different from that of the others. 
Diaphanoptera vetusta Brongniart 
Plate 28, B 
Diaphanoptera vetusta Brongniart, 1893, Recherches Hist. Ins. Fiss.:311; pi. 
17, fig. 9; Lameere, 1917, Mus. Nat. Hist. Natur., Bull. 23:147. 
This species was based on a well-preserved specimen, consisting of 
about the distal third of the wing, 20 mm. long and 10 mm. wide; 
the shape of the apex suggests a fore wing. Brongniart’s drawing is 
essentially correct, except that the first branch of Rs has an additional 
fork, which he did not show. The species is probably distinct from 
munieri on the basis of the reduced (i.e., forked) MP and the less 
extensive Rs. Of particular interest are the wing spots, some of which 
differ in location from those of munieri: there are two between R3 
and R4 + 5 and two between MPi and MP2, instead of only one, as 
in munieri. 
Diaphanoptera scudderi (Brongniart)

Diaphanoptera scudderi Lameere, 1917, Mus. Nat. Hist. Natur., Bull. 23 :149. 
This species was based on a poorly preserved fossil, representing a 
whole insect, the wings (33 mm. long and 11 mm. wide) resting 
obliquely along the abdomen and the cerci extending fully twice the 
length of the body ; suggestions of the thorax and two legs are present 
but are too vague to have morphological meaning. Brongniart’s figure 
is essentially correct. The wing venation is so obscure that no satis- 
factory description or drawing of it can be made; however, the pattern, 
so far as it can be seen, is consistent with that of Diaphanoptera. There 
are faint indications of the wing spots but their disposition is not clear 
because of the confused venation. 
Brongniart, not recognizing the affinities of this fossil with his 
Diaphanoptera , placed it in Scudder’s genus Anthracothremma , which 
had been established for an “orthopteroid” species from North Ameri- 
ca. Brongniart assigned Anthracothremtna to the “protephemerides”, 
along with Triplosoba. Handlirsch (1906) correctly removed scudderi 
from Anthracothremma, erecting a new genus, Pseud anthracothrem- 
ma, which he placed (1922) in Insecta incertae sedis. In the mean- 
time, however, Lameere (1917), during his examination of the 
Commentry fossils in Paris, had noted the similarity of the specimen
