REDESCRIPTION OF LITHOPHOTINA FLOCCOSA 
COCK. (MANTEODEA) WITH SOME NOTES ON 
THE MANTEOD WING VENATION 
By A. G. Sharov 
Paleontological Institute, Academy of Sciences, USSR, Moscow 
Dr. G. M. Byers recently sent to me for study the wing of an 
insect from the Miocene deposits of Colorado. I determined this wing 
to be the hind wing of a manteod, close to Lithophotina floccosa 
Cock., which Cockerell described in 1908 from the same deposits. At 
my request and with the approval of Dr. Hugo Rodeck (University 
of Colorado Museum) Professor F. M. Carpenter brought the 
holotype of L. floccosa to Moscow with him at the time of his visit 
to the Paleontological Institute. A study of the holotype led me to 
the conclusion that the hind wing which Dr. G. M. Byers sent most 
probably belongs to the same species, i.e. L. floccosa. A comparison 
with the venation of the fore and hind wings of the living manteod 
Chaeteesa filata Burm., which belongs to the primitive relict family 
Chaeteesidae, confirms this. L. floccosa also ought to be referred to 
this family. Since the description of L. floccosa given by Cockerell 
is very short, and since drawings are lacking and the photograph in 
the article is poorly reproduced, a redescription of L. floccosa , with 
a description of the hind wing of this species, is given below.

The fore wing of this species (Figure iA) was found in the 
Miocene deposits of Colorado (Florissant) at Station No. 14. The 
length of the wing is 21.5 mm, the width 7 mm. The wing is 
narrowed at the base. Sc is long, taking up more than two-thirds 
the length of the wing, ending at its widest portion. The branches 
of Sc close to the base of the wing have the character of cross-veins; 
in the center, together with the cross-veins which join them, they 
form a double row of cells; and close to the apex they take on the 
character of gently curving branches. At the apical portion of the

to Miss Helen V aitaitis for the English translation of the article.
