heap. In some instances the female was seen to separate the eggs by 
carefully passing her proboscis between them, and then drag them 
away or scatter them with her legs. In cases where the eggs were laid 
during extremis the female generally died on tin* spot, and made no 
attempt to scatter them. Counts were made of seven batches, the 
maximum being 71, the minimum 48; the actual counts were 48,48, 
54 * 57 . 59 . 62, 71. The incubation period, at an average temperature 
of 72 0 F. in the day and 65° F. at night, was two to three days 
Time of Appearance. They are ibundant during 
August and September ; but gradually diminish in numbers during 
the early part of October ;* and few examples are seen after a spell of 
cold wet weather. 
The Egg. Coriaceous; white at first, but changing to creamy 
white. Those which were laid on faeces, fully exposed to the sun 
had the exposed portions tinged with pinkish-brown, but this colour 
eventually disappeared. Form very elongate, shaped somewhat like 
a banana, being curved on one side and almost straight on the other 
du straight side with a broad deep groove which widens at the 
anterior end giving it a spatuloid form. Surface with faint polygonal 
reticulations. The larva effects its escape by Splitting the broad end 
of the groove, leaving it slightly raised (see PI. v. fig. 4). and apparent!) 
intact on the opposite side.
