yellowish. Feet concolorous with the body. Length en exclusion from 

 the egg, 4. ^ mm. The larva builds a perch at the end of a leaf in the 

 manner of Li7neiiitis larvae. 



Second stage. — Head large, rounded, densely covered with conical 

 tubercles, with three spines arranged in a triangle at the apex of each 

 lobe ; pale greenish, with a brownish tinge, and two brown shades, one 

 before and one behind the eyes on each side, running nearly to the vertex. 

 Clypeus small, triangular, pale ; jaws brown, ocelli and the three apical 

 spines black ; many of the longer tubercles at the sides of the head are 

 tipped with black ; width 1.8 mm. Body of uniform width, densely 

 covered vvith yellowish conical tubercles and a subdorsal row of tuber 

 culated processes, those on joints 3, 4, 6 and 12 much larger than the rest 

 (especially the one on joint 3), and ending in four or five black conical 

 spines. Colour pale brownish yellow, paler subventrally, with indications 

 of a blackish subdorsal band. As the stage advances the dorsum becomes 

 shaded with brown. 



Third stage. — Head larger than the body, flat behind and somewhat 

 flattened in front, not bilobed, but central suture depressed ; clypeus 

 small, densely covered with tubercles and a double row of long conical 

 spines along the sides and over the vertex ; another spine below the vertex 

 of each lobe, and a large rounded tubercle above the ocelli. Reddish 

 brown, the clypeus, a band on the ocelli tapering upward to a point, and 

 all the tubercles and spines yellowish-white ; ocelli and the tips of the 

 vertical and lateral spines black ; width 2.8 mm. Body as before, densely 

 tuberculated, many of the tubercles in the subdorsal and subventral 

 regions partaking of the character of branching spines. On joints 3, 4, 

 6 and 12 are a pair of large, thick, subdorsal processes (2.5 mm. long), 

 covered with granulations and large conical spines like those on the head ; 

 on joints 8 and 11 a smaller but similar pair. General colour light red- 

 dish-brown, with a greenish tinge, especially on the sides. The processes 

 are brown, most of the tubercles and spines yellowish<but the larger 

 spines are tipped with black. Traces of a black subdorsal line and black 

 dorsal marks between the long processes. 



Fourth stage. — Head very large, flattened before and behind, almost 

 disc-like, not bilobed, the outline from in front obtusely conical ; clypeus 

 rather small ; median suture deeper on the vertex than elsewhere. Front 

 nearly smooth, with only a few slight granulations, but around the lateral 

 edge and vertex is a double row of long spines, the vertical ones most
