Pedinaspis marie var. antennalis var. nov. 
Colored in general like typical P. marie; the thorax reddish, abdomen 
mostly reddish, basal segment rather darker, second with dark tip, 
third and fourth mostly black, pale on base, fifth and sixth with silvery 
sericeous hair; venter pale on base, black toward tip; wings marked as in 
P. marie, but the pale band broader and more distinct. It differs from 
P. marie in having the first and second joints of the antennz reddish, 
and in the reddish clypeus; the legs are almost wholly black as in P. 
marie. The posterior face of the metanotum is transversely rugose, 
more than in P. marie. Smaller than that species.

antenne (except basal joints) yellowish; wings colored as in P. chry- 
sothemis, broad basal and apical dark bands, no pale tips, middle 
yellowish, but not very bright. The fourth ventral segment has two 
oblique rows of long curved bristles (as in P. elegans), and on fifth 
segment lateral rows of erect hair, between these hair combs the surface 
of the fourth and fifth segments is polished and slightly depressed. 
The subgenital plate is elongate, somewhat hairy towards tip, and with 
a faint basal median carina. The metanotum is transversely wrinkled, 
no ridge separating the posterior slope, which is also partly wrinkled, 
the lateral angles fairly prominent, but dentate. Third cubital cell 
fully as broad as long. Size of P. mildei.
