ORIENTAL COLLEMHOLA. 103 



longiiudine a'quaUbas. Cnguicalus superior duobas dentibiis 

 armaias ; anyuicnlus inferior lanceolatus. Mucrones lati denti- 

 culis quinque. Long. 2'5-3"5 mm. 



Head — Equal in length to the niesothorax. The eyes eight 

 in number on each side ; post-anten7ial organs absent. 



A7itennrp. —HMghtly longer than half the total length of the 

 body (including the head). The first three joints subequal in 

 length, the terminal joint a, little longer than the preceding 

 ones. The first two joints clothed with long and conspicuous, 

 erect, almost black setse ; the joints in consequence appearing 

 greatly swollen to the naked eye, and like " bottle brushes " 

 when viewed under the low power of the mici'oscope (fig. (38). 



Trunk. — Clothed with both hairs and scales with many 

 transitional structures between the two (fig. 47). The segments 

 related to one another in length as 12 : 5 : 4 : 5 : 5 : 44 : 4 : 2 ; 

 the fourth abdominal segment longer than lialf the total length 

 of the trunk. 



Leqs. — Long, the third pair longest of all and extending to 

 the apex of the abdomen. A single long tenent hair in relation 

 with each foot. The superior claiv of the first and second pairs 

 of legs long, and gradually taj^ering to a point (fig. 45), armed 

 with two teeth along its inner margin ; one tooth situated at a 

 distance from the base of the claw equal to one third of the 

 total length of the claw, the second tooth placed at the same 

 distance from the apex of the claw. The inferior clatv lanceolate 

 and acuminate, unarmed, but in occasional specimens its inner 

 margin shows minute rudimentary serrations. The superior claw 

 of the third pair of legs slightly broader than that of the pre- 

 ceding pair ; the inferior claw with a minute tooth at its 

 base on the inner margin. 



Ventral Tube. — Long and cylindrical, the vesicles bilobed 

 (fig. 68). 



"Furcida. — Beaching to the ventral tube ; clothed ventrally with 

 scales. Tlie denies scarcely narrowing to their apices, a little 

 longer than the manubrium, armed witii a longitudinal row of 

 short stout lanceolate spines along the middle of the inner 

 lateral margin of each (fig. 46). Towards the ajiex of the dens 

 the spines become i-eplaced by stout setre. The mucrones with 

 two large terminal teeth, two smaller dorsal, sub-apical teeth, 

 and a lateral tooth (fig. 55). 



Coloration. — Seen with the naked eye when alive, it appears 

 bkck with a conspicuous yellow band across the abdomen. It 

 varies from very deep purple-brown to black, with an extremely 

 variable arrangement of the colour- pattern. In the majority 

 of individuals, the base of the metathorax, and the first and 

 second abdominal segments are pale yellow suffused with purplish 

 brown. The first two j.oints of the antennte are similar to the 

 ground colour of the body, the third and fourth joints vary 

 from yellow to dark violet. At the base of each joint, in five 

 out of the six specimens, there is a narrow transverse banrl of pale
