bearing three setae. The maxilla (Fig-. 10) is composed dis- 

 tally of the maxillary palpus (b) and the maxillar lobe (Fig. 

 10, a; Fig. 11). The conical maxillary palpus is four-seg- 

 mented, the tip of the last segment being somewhat blunt 

 and with a slight depression. The maxillar lobe terminates 

 in a finger-like sensory organ (Fig. lie), which is attached 

 to a rather stout basal portion. Surrounding this organ 

 are eight or more spines, which appear to be for the protec- 

 tion of the central organ. The labium is typical, bearing two- 

 segmented labial palpi ; the tip of the last joint of each labial 

 palpus is blunt and with a slight depression, similar to that 

 of the end segment of the maxillary palpus. 



The thoracic segments are concolorous with the abdomen 

 and bear numerouus tubercles, excepting, however, the pro- 

 thorax. The cervical shield is bare of tubercles, but the 

 prothorax bears a large tubercle just below, on each side 

 of the shield and above the anterior pair of legs. On each 

 of the second and third thoracic segments there are eight pairs 

 of tubercles above the legs, and each of these tubercles is 

 abundantly supplied with setae. On the ventral side of each 

 thoracic segment is a pair of rather large tubercles situated 

 in the middle of the segment and coalescing more or less 

 into one large oblong tubercle. Posterior to these ventral 

 tubercles and slightly farther apart is a pair of very small 

 sub-tubercular areas, with a single seta arising from each. 

 The more dorsal tubercles fall into four longitudinal rows. 

 Legs rather short and stout; the femur and tibia are well 

 developed, but the tarsus is small and bears a single claw. 



Abdomen nine-segmented, with many setiferous tubercles 

 arising from all the segments, except the ninth ; color dark 

 brown or almost black; spiracles are present on all abdominal 

 segments, except the ninth ; there are no abdominal legs. The 

 tubercles are similarly situated on the first eight abdominal 

 segments, but the dorsal tubercles differ from those of the 

 thorax in that they do not fall into four longitudinal rows; 

 the four anterior dorsal tubercles of each segment are more 

 widely separated than the four posterior dorsal ones (Fig. 

 12). Besides these eight dorsal tubercles there is another
