Of the above, not mentioned before, the first transverse 

 cubital separates this cell from the areolet. The disco-cubital 

 nervure which separates it from the third discoidal cell has quite 

 a prominent stump of a vein near its middle known as an abbre- 

 viated cubital nervure which extends into the cell. About half- 

 way from this stump, to the triangular areolet is a short bulla. 

 This cell is separated from the second discoidal cell by the dis- 

 coidal nervure and receives but one recurrent nervure at the 

 ])oint where the disco-cubital and discoidal nervures meet. 

 There is but one completely enclosed sub-marginal cell which is 

 regarded as the second or areolet. It is small, approximately 

 triangular and in all the specimens I have examined, the second 

 transverse cubital nervure which separates this cell from the 

 third sub-marginal coll has a bulla extending half way from the 

 base to the apex of the triangle, beyond which the vein bends 

 slightly, taking a straight line to the apex of the triangle. 



The third sub-marginal cell is separated posteriorly from the 

 second apical cell by the cubital nervure, and extends to the 

 margin of the wing. Its other bounding lines have already been 

 described. Submedian or internomedial cell is quite long and 

 narrow, the externo-medial nervure separating it from the 

 median in front, and the first abscessa of the anal nervure from 

 the anal cell behind. Outwardly it is separated from the second 

 discoidal cell by the transverse medial nervure which joins the 

 externo-medial nervure just beyond the origin of the basal 

 nervure, thus making it post fercal. The second discoidal cell 

 is separated posteriorly from the an^il cell by the second abscessa 

 of the anal nervure which is about one-half the length of the 

 first abscessa. Outwardly it is separated from the third dis- 

 coidal cell anteriorlx- and first apical cvW ])osteriorly by the first 

 recurrent nervure. that i^ortion of this nervure however sej)- 

 arating it from the formcT is nuich shorter than the latter. The 

 first recurrent nervure has a small bulla ])atch where it joins the 

 margin of the wing. The third discoidal cell is separated pos- 

 teriorly from the first apical cell by the first abscessa of the 

 subdiscoidal nervure and outwardly from the second apical 

 cell by the second recurrent nervure, at the center of which 

 is a distinct bulla ])atch, while at its anterior extremity just 

 below the areolet is another small bulla. The second apical 

 cell is separated posteriorly from the first apical cell by the 

 second abscessa of the sub-discoidal nervure which is much
