tubercles, from each of which issues a transparent and colorless 
straight or slightly curved cylindrical waxy rod. 
When first deposited these larvee are of a reddish-brown color, the 
antenne and legs paler, and the eyes dark purplish, which soon changes, 
however, excepting the under side of the body, to a beautiful, brilliant 
dark metallic blue or green, while others change to bluish-green, pur- 
plish, or to a brassy or coppery reflection. The antennz are short, 
four-jointed, and inserted on the under side of the head. The first 
joint-is shortest, stoutest, and slightly conical; joint two is somewhat 
longer and slightly clavate; the third is longest, cylindrical and about 
one-third longer than the second, while the last is a little shorter than 
the third and bears the usual sensorial thumb near the apex, the tip 
being surrounded with a few short hairs. The rostrum is stout and 
reaches beyond the median coxe. 
Legs stout; the tarsal digitules are 
long, capitate and curved; those of 
the claws are much finer, straight, 
and only about half as long as the 
others. There are also two or three 
long and stout, backward curved 
bristles near the end of the hind 
tibie, and two similar ones on the 
hind tarsi.

though they do not reach to the 
lateral margin. The surface of the body is now finely rugose and its 
lateral margin surrounded by a very short fringe of waxy secretion, 
issuing from closely set secretory tubercles. The antennz are now 
much shorter than before and only three-jointed; the two basal joints 
are short and subequal in length, while the third is about as long as 
the two basal joints together, slightly tapering and truncate at the 
tip. The rostrum has become shorter and reaches only to the median 
coxee. The legs are also shorter, while the anterior and median legs 
have lost their tarsi, which sometimes are indicated by a minute, knob- 
like swelling; the posterior pair of tarsi are still present, though rather 
short, irregular in outline and have lost the claws; the digitules are 
still present, though rather short and fine. The color of the insect is 
now of a dull black or dark brown.
