rated, on dorsal surface towards the occiput. A minute hair 

 oil the lateral margin of the head a little way behind the 

 antenna. A larger hair on the dorsal surface in front of the 

 embossed area near the base of the antenna. Two minute 

 hairs on the postantennal groove. At the base of the oral 

 cone above, four small hairs widely spaced. A longer one on 

 eacii side at the base of the columnar oral opening. On the 

 ventral surface, at about the level of the middle of the first 

 segment of the antenna, two fairly small hairs, one on each 

 side of the middle line. Five or six minute hairs with large 

 alveoli on ventral surface of the oral cone. 



Thorax : the usual spiracular bristle. A small one on each 

 '' shoulder'' of the pronotum. 



Abdomen : the abdomen is thickly covered both dorsally 

 and ventrally by rows of elongate hairs of peculiar shape 

 (see fig. 1 h). Each hair is very long, witfi a rather small 

 circular "neck" broadening at once into a flat scabbard- 

 like structure, the lateral margins being parallel to each 

 other and the end truncate. Most of these clumsy-looking 

 integumentary appendages are twisted. A few are pointed 

 at the tips. 



There is a transverse row of these hairs, very closely placed 

 on the tergum of each segment, excepting the last, where, on 

 the anterior margin of the transverse band, there are two of 

 the long modified hairs, and on the posterior margin two 

 widely separated normal hairs, with a couple of elongate 

 hairs at each lower lateral angle. Ventrally, there is a trans- 

 * verse row of closely-placed, modified hairs on each segment 

 (up to segment 7), altliough at the base of the abdomen over 

 the firet tiiree segments (and the qualification applies to the 

 dorsal surface also) the chajtotaxy in the only two prepara- 

 tions at my disposal remains somewhat uncertain. 



On each gonopod, a single long bristle inside the margin 

 postero-laterally. Two or three short hairs on the margin at 

 the inner angle. Inside the inner margin just behind the 

 cross-bar three small hairs on each side. In front of the 

 cross-bar six minute hairs in a row. Running from just 

 behind the gonopod in an oblique row outwards, eight or nine 

 long spines placed closely to each other so that their alveoli 

 are contiguous. At tlie end of this row, but placed a little 

 further in, a powerful spine on each side of the genital 

 opening. Between these two spines or " thorns " are two 

 small patches of chitin of irregular outline, each with three or 

 four short hairs. 



On each pleurite two elongate bristles, situated along the
