larva; they are much compressed from before backwards, 
this being most marked in front. Though nearly plain a 
the actual dorsal, ventral, and lateral lines, the segments are 
very deeply incised in front and sometimes behind, though 
this is not marked behind in a plump larva: these segments 
have an indication of dorsal tubercles. The twelfth segment 
is smaller than the others, and is very narrow in front, as the 
last segments curve forwards and upwards; the thirteenth, 
still smaller, appears to be divided into two, and there is, in 
addition, a very distinct rounded anal tubercle. The dorsal 
vessel is a straight hiatus between the masses of white fat, 
and, though it is not so, looks not unlike a groove; and in a 
larva preserved in spirit the skin might readily shrink into it 
and actually make it one. Except the tubercles, dorsal vessel, 
and some of the intervals between the segments, the body is 
full of white fat disposed in small rounded convoluted masses. 
The spiracles are eight in number on each side: the first is 
near the anterior border of the third segment, about halfway 
between the dorsal and leg tubercles; the second is just above 
and in front of the lateral tubercle of the fifth segment ; the 
others are in the six following segments, in a little hollow , 
behind the lateral projection, and near the anterior part of the 
segment. The twelfth segment has a similar hollow, but no 
spiracle. In the third and fourth segments there are seen very 
early a pair of trachez on the side of each, which indicate the 
the Andrene &c. are by those of Meloé. In determining the
