 Plate 20. 



Specific Characters. — Body : about 0*74 mm. in length by about 

 0'71 mm. in breadth ; dorso- ventral dimensions 0"36 mm. A 

 slightly rounded oval in outline. The skin is soft, apparently 

 finely ridged, the ridges wide apart. The anterior part of the 

 dorsum has four longitudinal rows of gland-pores, each sur- 

 rounded by a strong chitinous ring and standing out prominently 

 like tubercles ; the posterior pair of the two inner rows lying 

 near centre of dorsum. Slightly posterior to these are a pair of 

 small plates and, a little wide apart, a pair of gland-pores similar 

 to the others. In centre of posterior part of dorsum is an ovate 

 porate chitinous plate with the apex directed posteriorly, and 

 on each side a gland-pore with strong chitinous ring. On the 

 edge of the body four or five similar pores occur on each side 

 (PL 20, fig. 1). The body colour is bright red, but all the 

 chitinous parts are a slaty blue. 



Palpi. — Length about 0'33 mm. Second segment, proximal 

 half of extensor surface with two small spines, distal half with 

 three small spines, directed towards inner edge ; flexor surface 

 nearly straight with one moderately long straight bristle 

 pointing obliquely forwards. Third segment of nearly equal 

 width throughout, flexor surface concave, extensor surface 

 with one small spine placed midway and a short one near 

 the distal end; a moderately long bristle is placed on the 

 outer edge of the distal end of the flexor surface ; anterior 

 portion of segment hyaline, permitting the base of the fourth 

 segment to be seen at the articulation. Foiu'th segment 

 about half the diameter of the third, flexor surface with a 

 tubercle midway and a long curving hair springing therefrom ; 

 proximal half nearly straight, the distal half concave, with 

 three or four short fine hairs arising from minute papillae; the 

 margin at the distal end has two straight hairs, and another on 

 the extensor surface ; end of segment blunt. Fifth segment 

 compressed laterally, short, curved, ending in four or five claw- 

 like processes, (PI. 20, fig. 3) ; colour a slaty blue, extremity 

 with a tinge of orange. 



Epimera. — First and second pairs very much like those of 

 Limnesia maculata, but with posterior margin rather more
