 associated with the typical form. This variety — which may be distinguished 

 as var. verecunda — occupies the small glandular pits at the base of the veins of 

 the leaf, the anterior half of the insect being concealed within them. The 

 female puparium and contained insects are usually contracted and considerably 

 contorted by this habit.
