Spilaptera packardi Brongniart, 1885: 63, pi. 5, fig 1 ; Brongniart, 1893: 338, 
pi. 20, fig. 7; Handlirsch, 1906: 102, pi. 11, fig. 16. 
This species is based by Brongniart upon specimen 20-7, which is 
a well preserved fore wing with a perfect color pattern. 
Fore wing: length 53 mm, width 16.5 mm, broadest at midwing. 
Light spots, mostly oval in shape, occur between the cross veins as 
shown in figure 10. Anterior margin concave. Posterior margin 
parallel in the proximal half with anterior, then concave. Apical 
part abruptly narrowing, the apex pointed and located about on the 
wing axis. Postcostal area, with two simple veins originating on Sc. 
Subcostal area broad in the proximal third, very narrow distally. 
R-Rs area with only about 4-5 strong cross veins in its distal half ; 
Rs with about five very oblique simple branches ; MA with four short 
branches; MP forked about three times; CuA with a series of about 
six branches; CuP simple; anal area relatively large, with about 
eight branches, sometimes forked. Cross veins very few, strong, 
mostly curved, forming rows. 
S. packardi differs from Ubelluloides in its color pattern, the shape 
of the fore wing, the simple CuP, and the presence of fewer cross 
veins.

Spilaptera Ubelluloides Brongniart, 1885 : 63; Brongniart, 1893 : 339 pi. 20, 
fig. 8; Handlirsch, 1906: 103, pi. 11, fig. 17. 
This species is based upon specimen 20-8, originally consisting of 
part of the fore wing and a small fragment of the hind wing. After 
I had removed more of the matrix, all four wings, with almost 
complete venation, could be seen. The body, which was partially 
described by Brongniart (1893: 340) is insufficiently preserved for 
study. 
Wings of equal length, with narrow dark bands, about seven in 
number, irregular and more concentrated in the apical part of the 
wing, as shown in figure 11. Anterior margin concave, the posterior 
margin as a whole is moderately concave and very slightly undulated. 
Fore wing: length 57 mm, width 21 mm, broadest at the end of the 
proximal third ; apical part abruptly narrowing and short, the apex 
pointed and located on the wing axis. Subcostal area not markedly 
broad in the proximal third. R-Rs area with about 5-6 strong cross 
veins, surrounded by color markings in the distal half of the wing;
