Text-figure 17 
Fore wing: length, as preserved, 20 mm. width, 7 mm.; estimated 
complete length, 30 mm. Venation so far as known like that of 
recta, except that the main veins are almost consistently forked at 
the wing margin, the branching of R is less, the main veins are thicker, 
and the cross veins are thinner and more irregular. In addition the 
wing has several distinct maculations, as shown in the photograph, 
plate 4. The wing of recta shows no signs of markings of any kind. 
Holotype: No. 5873ab, Museum of Comparative Zoology (Col- 
lected by F. M. Carpenter) , in the lower layer of the Elmo lime- 
stone ; this consists of a distal two-thirds of a wing, which is somewhat 
wringled along the posterior border but otherwise very well preserved. 
Family Permelcanidae Sharov 
Permelcanidae Sharov, 1962, p. 112. 
Fore wing: membranous or very weakly coriaceous. Precostal 
area well developed but not forming a prominent bulge, extending 
about one-fourth wing length from base ; Sc extending slightly be- 
yond mid-wing; R distinct from Sc basally; Rs arising near or just 
beyond mid-wing, usually anastomosing with a branch of MA for 
at least a short distance; Rs and M with at least two terminal 
branches ; CuA as in the Oedischiidae, with several terminal branches ; 
CuP close to iA; iA with several veinlets leading to the hind mar- 
gin ; 2A and 3A much shorter. Cross veins much fewer than in the 
Oedischiidae, not forming a true reticulation. 
Specimens showing both fore and hind wings have not been found, 
but isolated portions of hind wings, consisting mainly of the remi- 
gium in each case and probably belonging to this family, have been 
described by Sharov. In these hind wings the costa is short and 
submarginal; Sc, Ri, Rs and M are essentially as in the fore wing; 
an anal area was presumably present although only a suggestion of 
one is visible in the fossils. The body structure is unknown. 
Three previously described genera belong here: Promartynovia 
Tillyard, from the Elmo limestone, Kansas; and Permelcana Sharov 
and Proelcana Sharov, from upper and lower Permian, deposits, re- 
spectively, in the USSR.
