Shape. — Prothoras and 9t.h abdominal segments very much reduced, being very 

 much smaller than the segments between them. Middle segments are the largest. 



Structure dorsaUy, under 1 inch objective. — Head covered with an almost 

 countless number of elevated dark tubercles of various sizes, each with a single hair, 

 they appear to be arranged in definite transverse series. The suture of the lobes is 

 free from tubercles of any kind. The minute white tubercles are very numerous. 

 Prothorax, much reduced, appears more like a subsegment of the mesothorax ; it 

 has dark sublateral tubercles with single hairs and minute white tubercles, none on 

 mid-dorsal line. Meso- and post-thorax have sublateral spiny tubercles, one each 

 side, seven or eight bristles on one base, numerous white tubercles, none on mid- 

 dorsal line. First and each succeeding abdominal segment (except 8, 9 and 10) 

 have a spiny tubercle on mid-dorsal line, anterior to the sublateral spiny tubercles ; 

 8 has a kind of hump with small hairs instead of elevated bristles ; 9 is without the 

 mid-dorsal spiny tubercle, but has the sublateral spiny tubercles (one each side), 

 these are not so well developed as the sublateral spiny tubercles on lu. 



Structure laterally.- -Head : the ocelli are very prominent, elevated, round and 

 dark ; antennse comparatively small, terminated by a bristle, two small points, and 

 a minute jointed process. Prothorax with an anterior transverse series of single 

 haired tubercles. The spiracle is placed well down the segment just above (?) supra- 

 spiraeular line ; below the spiracle are several tubercles larger than the majority of 

 single haired tubercles, and above the base of the legs is an elevated spiny tubercle. 

 Mesothorax : there are three spiny tubercles on anterior edge (one above the other) 

 above the pale spiracular area, below are several rather prominent single haired 

 tubercles arranged longitudinally on the second spiracular line, and below these is 

 the spiny tubercle above the legs. Post-thorax as mesothorax except that the spiny 

 tubercles are more central than anterior. On the first abdominal segment the mid- 

 dorsal spiny tubercle being anterior to the posterior trapezoidal spiny tubercle, the 

 supra-spiracular spiny tubercle is below the latter, and immediately above the 

 spiracle ; below is a dark round scar, and a subventral tubercle with three or four 

 hairs (not so distinctly an elevated spiny tubercle) ; 2nd, the round scar is here a 

 spiny elevated tubercle ; 3, 4, 5, 6 have abdominal feet, with the subventral tubercle 

 on base ; 7, 8 correspond to 1 and 2 ; 9 is very much reduced, and appears more 

 like a subsegment of 10, it has only the sublateral spiny tubercles already mentioned 

 (of course numerous secondary tubercles are present as elsewhere), 10 has in addition 

 to the sublateral spiny tubercles a great many tubercles of various size. The spiny 

 tubercle below spiracle is really the anterior subspiracular, as in the smallest specimen 

 examined the posterior subspiracular was present on each abdominal segment, being 

 a rather large black tubercle (not elevated) witli apparently only one hair, this was 

 the only perceptible difference between large and small, as this posterior subspira- 

 cular tubercle could not be traced in the large one. 



Structure ventraUy (under i inch). — Hooks of the abdominal feet consist of 

 about three alternate rows of hooks on inner side only, representing a rough cres- 

 cent. The claspers have two or three hooks only on posterior edge. 



The pup88 are attached to the under-side of one of the leaves 

 which form part of the tent, sometimes the leaves forming the tent 

 are severed at the stalk end, and sometimes none are severed, being
