pronounced convex curvature along the posterior margin between 
CuA and CuP; subcostal area narrow; Sc long; Ri without terminal 
branches; Rs long, originating in the basal third, with 2-3 branches; 
MA forked several times, MP somewhat more extensively branched; 
CuA giving rise to several branches; CuP forked several times; anal 
area with many forked branches. 
Lamproptilia differs from all other spilapterid genera in the very 
broad and short wings, and in having the prominent anal-cup lobe 
in the hind wing. The venation, characterized by numerous cross 
veins, is suggestive of that of Tectoptilus , Palaeoptilus , etc.

This species was based on a single specimen (19-8), consisting of 
an exceptionally well preserved fore and hind wing with striking 
color pattern. Unfortunately, only the reverse half of the fossil 
could be found in the collection of the Museum; this shows the color 
much less clearly than the obverse, as is often the case with the 
Commcntry insects. Fortunately, the color markings are very well 
shown in a photograph of the obverse made by Professor Carpenter 
in 1938. A drawing of the wings of this species, based on both ob- 
verse and reverse, has been published by Laurentiaux (1953, fig. 20). 
The following account is based upon the reverse of the type specimen. 
Fore wing: length 75 mm, width 23 mm; almost oval in shape, 
broadest at about midwing; membrane dark, the veins and cross veins 
light; several oval light spots framed by dark pigmentation are dis- 
tributed as shown in figure 19; anterior margin slightly concave at 
its middle; posterior margin undulated; apex broadly rounded. Sc 
long, Ri without terminal branches; R-Rs area only a little broad- 
ened with a dense series of oblique cross veins; R with only three 
branches, two of them forked ; MA forked three times, MP six 
times; anal area with about ten branches, mostly forked. Cross veins 
mostly regular, bordered by irregular, white stripes; anastomosis of 
cross veins in the anal area very rare. Hind wing: length 70 mm, 
width 33 mm ; light oval spots concentrated in the distal half and
