^ . — Head, yellow area in the centre more extensive, broad, flat, 

 yellow scales abundant ; })aij)i black, terminal joints slightly inflated, a 

 little longer than the proboscis ; both terminal joints and apex of the 

 antepenultimate densely covered with long hairs, some very stout ones at 

 the apices of the jomts. Mesothorax with the band of golden scales con- 

 spicuous. Terminal clasp segment slender, curved, slightly swollen in the 

 middle, apical spine blunt, about one-fifth length of limb. Basal clasp 

 segment with a large apical lobe; claspette a well-developed lobe near the 

 base, covered with short spines (no long ones present). Harpes, bases 

 villous with fine hairs, at the apex of each a recurved sickle-like portion. 

 Harpagones deeply infuscated, with a strong recurved spine on each. 

 Unci membranous, separated, each terminating in a point. Setaceous lobes 

 pyramidal, with about ten strong 'carved spines along the internal borders 

 only. Ungues of the fore and mid legs unequal, the larger claw with two 

 teeth, the smaller with one. Ungues of the hind legs equal and 

 uniserrate. Length, 4 ram. 



Notes on the adult larva. — Head broadly elliptical, long diameter 

 transverse, deeply infuscated. Antenna subcylindrical, with a slight curve 

 inwards, infuscated uniformly. Apex with four short spines, one much 

 longer than the others. Surface with scattered large chitinous spines ; 

 the upper surface h^s in addition several longitudinal rows of minute 

 spines running the whole length of the shaft, the points of these spines 

 directed inwards. Tuft below the middle of about eight short hairs not 

 reaching to the apex of the shaft. Upper and lower epistomal hairs 

 single, a small compound hair on the inner side of these, anteantennal hair 

 tuft of 7-S divisions. Mentum triangular, with about 30 small teeth. 

 Thorax and abdomen sparingly covered with fine set?e Two large hairs 

 on each side of the first abdominal segment, a single large one on all the 

 others. Comb of about ten scales in a single curved row, each scale with 

 a strong apical spine and a number of fine setj\i on each side, spine as 

 long as the body of the scale. Air tube 2x1, deeply chitinized except just 

 below the apex, subconical, slightly swollen above the base. Rows of 

 pecten teeth insertions reaching up half the tube. Teeth evenly spaced, 

 about twelve in number, each with several small denticles on the inner 

 side ; these are progressively smaller from above downwards. A pair of 

 large compound hairs at the level of the upi)er pair of teeth. Band 

 ringing anal segment about two-thirds as long as broad ; ventral group of 

 hair tufts (about ten pairs) from a separate barred area; dorsal group com- 

 posed of a pair of compo md and simple hairs. Anal gills unequal,
