Fig. 7. — Male. As this insect was four days travel- 

 ling by post it probably is somewhat drier and shorter 

 t han those taken immediatelyfrom the vine. The insect, 

 however, was quite lively when drawn, e represents 

 the size it bears relatively to the perfect female below. 



Fig. 8. — The female with her single fecundated egg. 

 Those two figures are drawn to the scale of the larvae 

 in Plate CXXV.
