The day on which the foregoing observations were made was a 
delightfully bright and sunny one, and the hour from 3 to 3 45 in tin 
afternoon; later, when the sun had lost its power, the flies 
disappeared, in their usual way, to find some sheltered spot in which 
to pass the night. 
The eggs which were procured on this occasion were kept at a 
temperature varying between 64° and 67° F. ; under these conditions 
the larvae did not begin to hatch until the cighth day, thus the 
incubation period was greatly prolonged ; had they been left in the 
warm grass, where the temperature near the surface was 70 0 F., they 
would in all probability have hatched, as they .lid in til- summer 
months, on the second or third day. 
Whether the larvae of these autumn broods will pupate before 
»e w.nter is at present impossible to say, but judging from the higi
