distal part forming a fine reticulation; area between CuA and CuP 
with numerous oblique, parallel branches, mostly slanted towards the 
posterior margin and parallel to CuP ; anal area with numerous 
cross veins forming a reticulation. 
Generic limits of Blattinopsis are very difficult to make because 
of the obvious variation in the venation within species. I consider 
it advisable to treat this genus broadly, as was done by Kukalova. 
The type-species, Blattina reticulata Giebel, is not so well known as 
several others, but there is no question about its basic venation. The 
genus has been recorded from Upper Carboniferous and Lower Per- 
mian strata of both Europe and North America. The probable 
generic synonomy has been discussed by Kukalova (1965). 
Blattinopsis kukalovae, n. sp. 
Text-figure 7 
Fore wing: incompletely known; estimated length, 22 mm.; h@lo- 
type (basal half of wing), 12 mm.; width 7 mm. Costal margin 
nearly straight, not conspicuously arched; costal area narrowed at 
wing base; venation typical of the genus; Rs arising from a single 
stem; M (in holotype and paratypes) with a deep fork; cross veins 
in costal area and between Ri and Sc, and Ri and Rs very close 
together and parallel, almost without cellules; reticulation between 
branches of Rs, M and CuA. 
Plolotype: No. 630 lab, Museum of Comparative Zoology; con- 
sisting of basal half of a wing; collected by F. M. Carpenter in the 
upper layer of the Elmo limestone. 
Paratype: No. 6302ab, Museum of Comparative Zoology; con- 
sisting of a more distal portion of the wing, lacking the apex; para- 
type No. I5582ab, Peabody Museum, Yale University; collected by 
C. O. Dunbar; middle portion of the wing, not so well preserved. 
A third specimen, No. 15633b, Peabody Museum, is a small frag- 
ment which probably belongs to this species. 
This species has the wing form and size of the type-species of the 
genus, but it lacks the reticulation in the area between Ri and Sc, 
and the subcosta is considerably shorter than in reticulata. It differs 
from most of the species described by Kukalova from the Permian 
of Czechoslovakia in having ( 1 ) the costal margin smoothly curved, 
(2) less reticulation of the cross veins and (3) a much less con- 
spicuous lobation of the anal area. 
The species is named for Dr. Jarmila Kukalova of Charles Uni- 
versity in Prague, in recognition of her achievements in both collect- 
ing and studying the Permian insects of Moravia.
