246 DE. J. <^' DE MAN ON THE PODOPHTHAI/MOTTS 



inferior one being tlie broadest and undivided (divided by a narrow 

 white space on the propodites of the legs of the second pair) ; 

 the two superior are narrow and separated by a broad white 

 space, which is even broader than the white space between the 

 middle line and the inferior one. These lines are continued, in 

 the same manner, on the outer surface of the carpopodite, mero- 

 podite, and ischiopodite ; whereas those of the inner surface are 

 little distinct. The inferior line on the outer surface of the pro- 

 podites of the legs of the third pair appears, however, to be 

 constantly divided into two lines on the outer surface of the 

 following joints, so that the outer surface of the carpopodites is 

 marked with four narrow red lines, of which the two superior 

 are separated from one another by the broadest white interspace 

 and with a fifth red line near the under margin. The legs of 

 .the fourth pair also present some red lines. 



In very young specimens the two red, lines which are found 

 on the outer and on the inner surfaces of the dactylopodite are 

 not divided into secondary lines on the other joints, but are con- 

 tinued on them undivided.
