at points in the middle of the segments there appear minute cones of 
secretion, which form transverse lines across the dorsum. 
In boihng NaOH the colour becomes reddish but the liquid remains 
practically colourless. When stained and mounted the dermis is almost 
clear, but exhibits two " eye-shaped cicatrices " between the antennae and 
the position of legs I., and two others about an equal distance from the 
posterior extremity. The gland-pores of the venter are small and few 
in number. Those of the dorsum are about three times the size of the 
ventral ones, and are most numerous in transverse rows across the 
segments. There are a few scattered hairs ; some situated between 
the antennae being long (70 fi). The eyes are prominent, conical, and 
retain the stain. 
The marginal spine areas comprise 2 spines and 5- to 8-grouped gland- 
pores (Fig. 33). 
The mentum is about 105 long. 
The antennae are uniformly 9-jointed, the measurements of the 
segments varying but slightly as indicated by the following range in fx: — 
(1) 34-40; (2) 68-74; (3) 61-68; (4) 34-38; (5) 40-46; (6) 34-40; 
(7) 30-34 ; (8) 30-34 ; (9) 56-62.
