Segment 2. A circular posteropleural spot. The two sternal spots 

 confluent in a large semicircular spot. A narrow band around 

 posterior end of segment. 



Segment 3. Anteropleural spot large and elliptical. The two sternal 

 spots confluent in a large blotch covering the lower sides and sternum 

 of this segment. 



Segments 4 and 5. Pleural spots absent. Sternal spots confluent, 

 but much more restricted than in segment 3. 



Segments 6 and 7. A small, round, anteropleural spot present. 

 Sternal marking a narrow ventral stripe, as in segments 4 and 5. 



Segment 8. No pleural spots. Sternal marking as in segments 4-7. 



Segments 9 and 10. Entire sternal area yellow. Vulvar lamina 

 yellow. Appendages black. 



Pile on abdomen short, scanty, and yellow. 



Figures 44-57 show the abdominal markings of 14 females. Because 

 of the shape of the abdomen, the sternal stripe of segments 4-8 does 

 not show. It is m all specimens as described above. 



Figures 14-25 show the variations in the vulvar lamina in 12 

 females. On the base of the lamma there is a black spot, which 

 varies in size in the different specimens. Figure 20 is a ventral view 

 of the same lamma as is shown in figure 5. 



The following table gives the measurements of the 14 females: 



The following tables give variations in certain characters of wing 

 venation in the females :
