This species is based upon Brongniart’s specimen 19-5, a hind 
wing lacking the basal part. 
Wings dark, with broad, light veins and cross veins. Hind wing 
only moderately broadened, broadest at about the first third; length 
48 mm, width 16 mm; anterior margin almost straight, posterior 
margin undulated; apical part relatively broad, apex rounded, lo- 
cated at about the wing axis; r-rs area slightly broadened, with 
numerous, weak and somewhat oblique cross veins; Rs with seven 
branches, the first being forked twice; MA with five simple, long 
branches; MP with six forks; CuA with a series of four long simple 
branches; CuP forked four times. Anal area large, with nine anal 
veins, most of them forked ; cross veins numerous^ regular, less dense 
in the anal area, broader and forming rows. 
This species has a unique coloration among the Spilapteridae. The 
apparent width of the veins is probably due to the accompanying 
white strips along the veins, rather than to the veins themselves. 
Genus Tectoptilus gen. nov.* 
Type species: Becquerelia grehanti Brongniart. 
The type species of this genus, grehanti , is known only from a 
single specimen, number 20-4 of Brongniart’s 1893 monograph. Al- 
though he placed the species in Becquerelia , this assignment was ques- 
tioned by Handlirsch (1906) and Lameere (1917), who referred 
it to the genus Epitethe Handlirsch. In the course of my study of 
the fossil, I have noted additional features which separate the insect 
from all genera which have been established. In the Museum col- 
lection, I have also found an unfigured specimen which seems to be 
conspecific with grehanti (figure 17). This specimen, being much 
better preserved than the type, contributes much information about 
the fore wings and certain body structures, which have been used in 
the following account. 
Wings dark with a light pattern. Cuticular thickening Y-shaped, 
extending into the area of CuP and Ai. Anterior margin slightly 
concave. The termination of Ri unknown but Rs pectinate, with 
few branches; MA with several branches, MP richly branched; CuA 
pectinate, CuP with an unusual number of branches, extending over 
a large area. Anal area with many branches also. Cross veins nu-* 
merous, simple or rarely irregular and anastomosed; posterior mar- 
*This generic name is based on the Greek word (tekton) for a carpenter 
and is used in honor of Professor F. M. Carpenter, Harvard University.
