right. 



8. Phwocyma exhausta, terminal segments of female abdomen from be- 



neath.

10. Phwocyma lunata, terminal segments of female abdomen from beneath; 



the bursa copulatrix is shown at the right, connected with the ringed 

 opening. 



11. Phwocyma s<ili<-is, terminal segments of female abdomen from beneath. 



12. Phwocyma edusina, terminal segment of female abdomen from beneath;

Plate XXXIV. 



Fig. 1. Phwocyma undularis, terminal segments of female abdomen from be- 

 neath, with opening to bursa copulatrix at the upper angle of righl 

 plate. On the other figures the opening is indicated in a similar way 

 and approximately it is near the upper junction of the two plates 

 lint always from the right plate. 



2. Phwocyma umbripenniS, same as the preceding and shows about the 

 extent of the variation found within specific limits. 



:;. Phwocyma wruginosa, terminal segments of female abdomen from be- 

 neath. 



I. Phwocyma insuda, terminal segments of female abdomen from beneath. 



5. Phwocyma norda, terminal segments of female abdomen from beneath. 



6. Phwocyma minerea, terminal segments of female abdomen from be- 



neath; practically like the preceding. 



7. Phwocyma lunifi /■». terminal segments of female abdomen from beneath.
