The subbasal and antemedial fasciae are wavy and the postmedial fascia is slightly incurved from the costa to vein 2 with a point on the proximal edge at vein 7, acutely angled at vein 2, then arched and inwardly oblique to the inner margin at one third, from the top of the arched portion there is a band, rising to the subcosta, bent and arched toward the base and terminating on the median nervure.

The more constant cross-veins are the humeral cross-vein ( h ) between costa and subcosta, the radial cross-vein ( r ) between R and the first fork of Rs, the sectorial cross-vein ( s ) between the two forks of R8, the median cross-vein ( m m ) between M2 and M3, and the mediocubital cross-vein ( m-cu ) between media and cubitus.
