margin extremely narrowly and weakly fused to 3Ax. FM2 moderately short; oriented 

 proximad; acerose; separated from FM1 by a long, narrow section of membrane. 



Third Axillary (Fig. 146) 



Head weakly convex; normal length. Proximal margin shallowly concave. Anterior margin 

 weakly concave; broad; narrow, not enlarged ventrally; from the proximal angle it slopes 

 antero-distad. Antero -proximal margin not extended anteriad. Antero-distal margin weakly 

 extended anteriad. AXCu occupies the proximal one-fifth of head; convex. FCu normal 

 size; distinct; occupies the central three-fifths of the head; deltoid. FA moderately narrow; 

 occupies the distal one-fifth of head. Anterior margin entire. Suture line between FCu and 

 FA present. Suture line between FCu and AXCu present. Suture line between FA and FJ 

 absent. 



Neck elevated proximally and weakly so distally. FCu section of neck absent. AXCu forms 

 entire neck; extremely small. Proximal margin elevated as a very narrow and short ridge. 

 Ridge extends to median of the proximal margin of tail; very short. Dorsal surface of ridge 

 is weakly curved proximad; enlarged dorsally relative to AXA. Prong armed with a single 

 broad but short tooth; oriented postero-dorsad. Detached AXCu fragment saddle-shaped; 

 strongly curved ventrad both anteriorly and posteriorly; slender; moderately sclerotized. 



Tail reduced; deltoid. Dorsal surface oriented laterad. Proximal margin strongly elevated 

 dorsad to the dorsal plane of the neck; slopes distad along its entire length. Anterior to 

 antero-median concave. Antero-median to posterior convex; oriented dorso-distad. Window 

 absent. FJ+AXJ broad; extends close to the dorsal plane of the neck; occupies the anterior 

 half of the tail; moderately sclerotized; curved distad. Suture line between FJ and AXJ 

 absent. Suture line between FA+AXJ and AXA present. AXA extremely short and narrow; 

 more strongly sclerotized than FA+AXJ; occupies the posterior half of the tail; curved 

 postero-distad. Suture line between AXA and AXCu present. 



Hind Wing Base Description 



First Basal Plate (Fig. 147) 



Humeral Plate moderately broad and long. Anterior margin concave; strongly sclerotized; 

 adjacent to BScA. Apex rounded; moderately broad; curved ventrad. Dorsal margin 

 convex. Proximal margin convex; curved ventrad. Ventral margin concave. Suture line 

 between FPC+BPC and FC+BC absent. 



Anterior Subcostal Basivenale oriented distad; broadly ovoid; convex; strongly elevated 

 dorsad. Proximal and distal sections separated by a prominent suture. Proximal section 

 extended anteriorly and postero-proximally as a moderately broad convexity; larger than 

 the distal section. Distal section discontinuous with the ScA bulge; separated by a 

 moderately deep concavity. Apex broadly rounded; oriented distad. 



Subcosta Anterior moderately convex; moderately extended posteriorly. Bulge moderately 

 broad. - Radial Basivenale convex; open; discontinuous with radial stem; angled antero- 

 proximad; broadly rectangular. Proximal arch slenderly deltoid; curved postero-distad. 

 Anterior section strikingly reduced by a greatly enlarged br; discontinuous with the anterior
