ORIENTAL COLLEMUOLA. 107 



The scales lanceolMte, the hairs finely phunose (compound). 

 Groups of strongly chitinised curved setse are [)resent along the 

 anterior border of the niesothoi-ax, forming a " fiill" or "collar," 

 and at the extremity of the abdomen. 



Leffs. — Long and slender ; the tibite divided by means of a 

 movable joint into a longer proximal and a shorter distal 

 segment. The femora of the first pair provided with several 

 extremely elongate slender (sensory ?) seta; along their inner 

 aspect (fig. 7()). The superior claws straiglit, as long as the width 

 of the distal joint of the tibia at the base (tig. 71); armed with 

 two teeth along the inner margin — one tooth situated at a 

 distance from the l)ase of the claw equal to ap[)roxinia.tely one 

 third the total length of the latter-, the second tooth situate<l at a 

 similar distance fi-om the apex of the claw. In many examples 

 there is a minute tooth placed between the distal- tooth and the 

 apex of the claw. The inferior claws straight and acumina.te. 

 In relation with each foot is a single stout tenent hair, broadly 

 expandeil at its apex. Pseudonychia long. 



Ventral Tahe. — Moderately long, cylindrical. The vesicles 

 were retracted in all the specimens examined. 



Ilamida. — Situated on the anterior third of the foui'th abdo- 

 minal segment. The corpus somewhat mammilated, armed with 

 a, stout, median backwai'dly directed spine. The rami short and 

 stout, each provided with four small teeth (fig. 72). 



Furcula. — Long and slender, as long as the trunk-region. 

 The denies parallel-sided or only very slightly tapering towards 

 their apices, clothed with numerous long hairs. 'J'he denies 

 related in length to the mamcbrium as 27 : 22. The vmcrones 

 stout and broad, wedge-shaped in sectional area ; armetl with two 

 large apical teeth, a lateral inside tooth, and a row of three dorsal 

 teeth (fig. 70). The distal extremity of the raucro armed with a 

 very stout rod-like seta on its inner side towards the ventral 

 aspect. At the base of each mucro on the dorsal aspect of 

 the dens is a scale-like organ* (fig. 70). 



Coloration. — The ground colour varying from dirty cream 

 colour to yellow, with indigo or violet-black markings disposed in 

 the following manner: — A lateral area on either side of the head 

 eiTibracing the eye-gi-oup ; a few small patches at the bases of the 

 antennas ; and irregular lateral markings on each of the thoracic 

 and abdominal segments which, Jiowever, are scarcely visible 

 dorsally. On the doivsal aspect of the fourth abdominal segment 

 are a few bilaterally symmetrical mai'kings, and a lateral patch 

 on either side of the fifth segment. The femora marked with 

 a distal band of violet ; a small proximal band and a more 

 extensive distal band of the same colour on the first joint of the 

 tibia. A pale violet sufiusion on the second (or distal) joint of 

 the latter (fig. 76). 



The general colour pattern, however, is very variable, arid for
