Kirkaldy separates this genus and Aneono from the other genera he 

 includes in the Eupterygidae by their having the second and third sectors 

 of the tegmen united in a stalk apically. His figures of the venation of 

 Aneono bear out his characterization for that genus, but further show so 

 extremely anomalous a venation as to exclude the group from this 

 family. 



In Dialecticopteryx the case is not so clear, however. From his figure 

 it is seen that the 2nd and 3rd sectors are united near the base, but this 

 is not a surprising departure for an Eupterygid. Theoretically all the 

 sectors join near or at the base, although usually they are visible nowhere 

 near that point. Now as to the other point of peculiarity claimed by 

 Kirkaldy his figure does not bear out his statement. The union of the 

 second and third sectors in an apical fork is merely their connection by 

 the usual crossvein. There is really nothing strikingly peculiar about 

 the venation of the apical part of the tegmen. The venation of the wing 

 in this genus is unknown and for that reason assignment to its proper 

 place in the family (if it really belongs here) is impossible.

 The chief character advanced for this genus, the large, elliptical swell- 

 ing on costa, is, I suspect, nothing but a pronounced costal plaque such as 

 I have discussed on pp. 110-111. The genus deserves recognition however 

 because the veins of the elytra are thickened and conspicuous basally, 

 something true of no other Eupterygid.

Aidola seems to be very closely related to Erythroneura, from which 

 the chief character advanced for distinguishing it is the presence of
