as wide as the costal space; Ri usually slightly sigmoidal; Rs usually 
arising at about one-quarter of the wing length from Ri and giving 
rise to several branches either dichotomously or pectinately; M ap- 
parently independent of R at the base, although very close to it in 
some species; M almost always with at least two terminal branches; 
CuAi apparently anastomosed with the stem of M for a considerable 
distance, diverging posteriorly from it just before the level of the 
origin of Rs, then coalescing for a variable distance with G.1A2; 
CuP arising from the stem of Cu near the base of the wing and 
continuing as a nearly straight, strongly concave vein; the posterior 
margin of the wing is usually strongly indented at the termination 
of CuP; 1 A usually very close to CuP and in some species apparently 
anastomosed with it; usually at least two other distinct anal veins 
present; cross veins highly variable in form, usually numerous and 
often forming a reticulation over the central and posterior portions 
of the wing; a curved transverse line, starting from Ri at about the 
level of the end of Sc and terminating on CuA at about the level of 
the first definite fork of CuA, is visible on the wings of most mem- 
bers of the family. 
The hind wings and body of the blattinopsids are almost entirely 
unknown ; a short, stout ovipositor apparently existed in some species 
(Kukalova, 1959). A fragmentary wing, probably a hind wing, is 
the basis of the description of Blattinopsis elegans Handlirsch (1906, 
p. 160), from the Upper Carboniferous of Germany; however, since 
this wing is not associated with a fore wing and since the venation 
of the remigium is distinctly different from that of the fore wing, 
there is no real basis for considering this to be a member of Blat- 
tinopsis. Laurentiaux (1950, p. 66) has established Blattinopsis in- 
certa (Upper Carboniferous of France) for a specimen consisting of
