IL The shield narrows between coxsp II and attains its greatest width between coxse 

 II and III and at the postero-lateral angles. The posterior margin is straight. It 

 is provided witli (i pairs of weaU. slender hairs, of wliicli one pair is situated on 

 a level with the niiddle of coxa IJ, two pairs, one closely behind the other, be- 

 tween coxae II and 111, one pair on a level Math the bind margin of coxa III, one 

 on a level with the front margin of coxae IV and the last pair half way between 

 coxa IV and the posterior margin. The ventral shield is large, triangulär; the broad, 

 Square anterior margin is contiguous to the posterior margin of the sterniti- ventral shield. 

 The antero-lateral angles and the sides are rounded. The bind margin is deeply ex- 

 cavated and surrounds the anterior half of the basis of the great peduncle, which 

 attains the length of half the body and offen is seen to brauch off into two. The 

 anal shield bears 6 pairs of slender liairs, two of which are inserted close to the front 

 margin. one near the antero-lateral angle, and two pairs, which are smaller and stouter, 

 on both sides of and in front of the peduncle. 



When the peduncle is cut off, the anal shield becomes visible. It is broad, 

 oval, twice as broad as it is long, and flanked by two pairs of short, pointed hairs. 



The endopodal shields (scuti endopodici Berlese) are distinctly separated 

 from the sternal shield and project half- way between the coxae with square 

 tips, which meet the pleural ridges of the parapodal shields. They coalesce behind 

 coxse IV with the large metapodal shields, the median edge of which is conti- 

 guous to the lateral edge of the sternal shield, and the posterior edge with the 

 anterior one of the ventral shield. 



The metapodal shields are distinctly separated from the parapodal shields by 

 a line, running obliquely backwards from the middle of coxa IV, thus parallel with 

 the lateral edges of the sternal shield. The shields do not reach quite as far as 

 to the ventral shield, the antero-lateral angles of which thus are contiguous with 

 the hind angles of the parapodal shields. The metapodal shields have a deep foveola 

 to receive the tips of tarsi IV. The parapodal shields are of the typical shape 

 and do not exhibit anything peculiar. The Stigmata are situated in the bottom of 

 the foveolse pedales III. The peritremata run obliquely forwards and outwards, 

 ascending the hind slope of the processi metapleuri (Berlese), run along the exterior 

 margin of foveola pedalis II and continue straight forwards to the niargin of the 

 body, exactl}' to where the limit is between the vertex and the dorsal shield. 



The rostrum is protected in front by a narrow. halfmoon-shaped plate, the 

 tectum, (PI. 3, fig. 14) the front edge of which is provided with nunierous teeth 

 and has a median, broad and triangulär projection. 



The epistoma is of the usual, long lancet shape; the edges of the distal half 

 are fringed: the tip ends to all appearance in a bündle of vcry minute flips. The 

 styli are long, blunt, more than half as long as the epistoma. 



The mandibles. The chela is small and narrow and resembles very much 

 that of Uropoda obovata C. & B. [Acari italiani Tav. 155]. The upper jaw ist longer 

 and stouter than the lower one and projects in a thin, vertical and rounded blade 

 in front of the blunt terminal tooth, and separated from it by a small incision. The
