other Corvine Nirmi in heavy chitinization of head and body, 

 showing as heavy, broad, transverse abdominal bands. 



Description of male : All coloured portions quite dark with 

 spaces between markings pale or transparent. Head bluntly 

 conical, semi-parabolic before the antennae with sides of front 

 flattened. Antennal bands blackish, continuous around the cl}^- 

 peus, but uncoloured where they meet in front, narrow, turn- 

 ing in before the antennae to form a black-edged blotch on 

 each side A median, inverted goblet-shaped clear space in 

 front of the mandibles, bounded on each side by narrow, dark, 

 not black, internal bands, losing their colour forward where they 

 meet the transparent portion of the marginal band. Remain- 

 ing area of head in front of antennae of a uniform, rather dark 

 brown Four evenly spaced clypeal hairs on each side of the 

 central clear space ; another smaller one on the angle before 

 the antennae and two more in front, quite long, extending from 

 the ventral surface. Antennae differing in the two sexes, being 

 a third longer in the male, with the first segment longest and 

 much enlarged ; second segment nearly as long and but little 

 shorter than the last two together ; fourth and fifth about 

 equal, while the third is a little longer than either of these 

 two ; each segment with several short hairs. In the female the 

 second segment is much the longest and the last is longer than 

 either of the two preceding. In both sexes the second, third 

 and fourth joints are more darkly coloured. Antennal bands 

 small, consisting of a small black blotch at the forward edge 

 of each of the prominent eyes ; eye with a short hair. Tem- 

 ples somewhat narrowly rounded, not expanded, with sides 

 somewhat flattened; the dark, narrow, marginal bands inter- 

 rupted on the rounded posterior angle, leaving a small clear 

 space from which arises a long hair ; some distance behind 

 this is a minute prickle. In figure 2 the temples appear a 

 Httle too much rounded, though there appears to be some varia- 

 tion in this respect, especially between the two sexes (fig. 2b). 

 Occiput but slightly concave, bate, pale in colour. Ocular bands 

 but partially visible, not meeting the occiput ; space between 

 bands clear, with signature visible, though indefinite. 



Thorax much shorter than head. Dark lateral bands on 

 both segments, turning in along their posterior margins, those 

 of the metathorax not meeting on the meson and much heavier 

 than those of the prothorax. Prothorax ordinary, with a long 

 hair in each posterior lateral angle ; metathorax longer than 

 prothorax with straight, diverging sides ; posterior margin obtuse- 

 ly angled on the abdomen, with a series of about fourteen sub- 

 marginal hairs. Legs well developed with long, narrow tibiae and 

 blackish markings. 



Abdomen elliptical, widest at the third and fourth segments, 

 each segment except the last with a dark blotch on each side, 

 much darker toward the lateral margins with clear spaces for the 

 spiracles on segments one to seven ; in some specimens these
