cubital vein; distad of posterior extension of brachial vein, the 
membrane is bordered by a narrow reticulate area; membrane 
with four spur veins, only one of which, the third from apex, 
appears to be a direct continuation of one of the other elytral 
veins (the cubital). 
Elytra, in brachypterous specimens, everywhere coarsely punc- 
tate, the claval suture obliterated and claval area solidly fused 
with remainder of elytron; the claval vein and upper part of 
brachial vein join, enclosing a distinct area additional to those 
observable in the macropterous elytron. Because of the absence 
of a membrane, the longitudinal veins are lengthened; further- 
more all the veins are more prominent than in macropterous 
specimens. For descriptive purposes, names of the elytral areas 
have been needed and those adopted are indicated in one of the 
accompanying figures. 
Fic. 1—A, macropterous elytron of Piesma, membrane stippled; B, 
brachypterous elytron of Piesma, elytral areas are named as follows: I, 
costal; 2, subcostal; 3, cubital; 4, claval; 5, interstitial; 6, brachial, and 7, 
sutural. 
Venter: fifth abdominal segment narrowed in middle, fifth 
and sixth each terminating at their postero-lateral angles in
