THE WING VENATION OP THE CONIOPTERYGIM1. 



By C. L. Withycombe, B.So., F.E.S. 



In my last note on the Coniopterygid® I described the vena- 

 tion of the forms under consideration in terms of Comstock's 

 system, applying such names to the wing veins as are given in 

 his book The Wings of Insects. This was done for the sake of 

 simplicity, while realising full well that some of the implied 



Conwentzia psocifortnis.— Fig. 1 fore wing, fig. 2 hind wing of pupa x 66 ; 

 fig. 3 fore wing, fig. 4 hind wing of imago x 26. 



homologies were not exactly correct. Strictly, the venation is 

 not so simple as at first sight appears. \ 



I had then worked out the papal venation of Conwentzia psoci- 

 formis, Curt., and was hoping to complete my study with that of 

 Semidalis, given by Comstock as typical of the Coniopterygid®. 

 Unfortunately my larv® of Semidalis, bred in captivity, are, 1 

 fear, not going to emerge this year as a second brood, probably 

 as a result of the cold season. Therefore the venation of Semi- 

 dalis cannot be settled this year, 



The fore wing of Conwentzia is of fairly normal type, but the 

 hind wing is strongly reduced, with correspondingly interesting 

 results in the venation.
