Pupa. 
Yellow tinged with red. Legs short. Cornicles 
slightly clavate. 
Late in the month of August I captured, in company 
with the viviparous females, a number of small pupae 
having large heads, prominent red eyes, and abdomens 
thickly barred with dark green. The legs and wing- 
cases were nearly white. 
Although I could not succeed in breeding the 
winged forms from these diminutive pupae I regard 
them as belonging to the males. I did not detect the 
oviparous female in company.
