tubercles, and the pair on the first abdominal segment is often of fair 

 size and swollen at the distal extremity (fig. 5). In other speci- 

 mens, however, this pair is short like the other pairs. The thoracic 

 suture is very distinct and curved and extends to the margin of the 

 case. The ''eye spots," which are present as in T-signatus, resemble 

 quite closely those of that species. The margin (fig. 6) is armed 

 with very prominent teeth, a space of 0.1 mm. being occupied by 6 

 or 7 of them. These teeth are rather long; are rounded at the tip 

 and covered with numerous distinct serrations (fig. 7). At the 

 base of each tooth there is a semicircular nearly transparent area, and 

 there is an indication of the separation of the submarginal area from 

 the dorsal disk. Caudal margin armed with a pair of long spine-like 

 hairs. Vasifonn orifice (fig. 8) situated on a prominent projection, 

 subcircular in outfine and almost filled by the operculum; lingula 

 not observable through the operculum. 



On the leaf the case is shiny black. There is a broad white lateral 

 fringe composed of a closely appressed series of wax rods, radiating 

 outward upon the leaf. The dorsum is more or less covered with a 

 similar secretion, which, however, is of a more imiform texture, no 

 visible rod structure being present.

Larva. — (fig. 14). — The larva is broadly elliptical; size 0.6 mm. by 

 0.46 mm. The median area is evident, but not distinctly elevated. 

 There are a number of prominent spines present, the position of 

 which is shown in the figure. The margin is dentate, with the teeth 

 evenly rounded; the thoracic tracheal folds are well defined (fig. 15). 



Pupa. — (fig. 10). — The pupa case is broadly elliptical with indenta- 

 tions marking the thoracic and caudal tracheal folds. Its size is 2 by 

 1.6 mm. Color yellowish with a shght brownish shade. The median 

 and subdorsal areas are evenly arched and sHghtly darker in color 

 than the submarginal area, which is very flat. There is no distinct 

 median ridge, and the vasiform orifice is but slightly elevated. The 

 submarginal area is armed with a row of usually 50 rather long spines, 

 arranged about the case as sho\vn in the figure. These are about 0.2 

 mm. long and each is spHt into segments at the tip (fig. 12). On 

 the submarginal area, between the marginal row of spines and the 

 raised central area, there are two more pairs of spines present. The 

 most caudal pair situated about opposite the vasiform orifice and the
