576 Mr. Harold Powell on the Hesperia sidae, Esp. 
ground. The glazed eye was quite black and the antennae 
cases dark. The butterfly should have emerged about this 
time, but after May 22 I concluded that it was dead. The 
abdomen had then shrunk considerably in length and 
girth. When I left Hyeres for Algeria early in May, I 
had to remove the pupa from the tent in which it lay 
ou the growing plant, and on the journey it probably 
suffered from want of moisture. The imago, as I found 
later, had fully formed but had died and dried up within 
the pupa case.
