The whole insect is of a very deep blue-violet colour. The cuticle is finely 

 rugose, and bears numerous bristles, many of which, especially on the terminal 

 alxluinmal segments, arc elongate, but none are feathered. The general aspect of the 

 species and the form of the foot are suggestive <f a Xmi/lla. 



Feelers. The feelers (figs. 1, 2) have characteristic sense-organs both on the 

 third and fourth segments. On the dorsal aspect of the extremity of the third 

 segment is a group of four short, sharp spines arising from large circular depressions in 

 the cuticle, and surrounded by a sinuous ridge (fig. 1, d). The two outer spine* of 

 this organ are stronger than the two central. At the tip of the fourth segment is ft 

 long tapering sensory bristle (fig. 1, b), and near it is a 8ul>-apical sense-organ (fig. 1, a) 

 consisting of an oval depression within which is placed a slender bristle. Close to this 

 are two small rounded papillae with a bristle at the tip of each. At the apex of the 

 fourth segment and directed ventral wards, a bladder-like protrusible organ (fig. 2, c) 

 can be seen in two specimens. 



Cephalic sense-organs. The most careful search has failed to discover any 

 trace of ocelli, and I believe that they are absent. In every specimen, however, the 

 poet-antennal organ (fig. 1, e) is prominent a simple chitinous ridge of oval or heart- 

 shaped form, varying in the details of its outline in different specimens <' "). Ik-hind 

 this is a structure, which appears to lie a sense-organ, hitherto undescribed, as I !.<];, -\ .-.
