is divided longitudinally into two parts. Along this division are 

 numerous brown patches. The rear half also has a brown spot just 

 forward of its center. 



The legs are yellow with the adjoining edges of coxa and trochanter 

 black. The first pair is the shortest. It has many spurs along its 

 inner edge. One is found at the distal end of the trochanter, three on 

 the femur besides one at its distal end, one is placed on a distinct 

 prominence near the end of the tibia, while a row of smaller ones runs 

 obliquely across this joint. The tarsus carries one spur and still an- 

 other is located at the base of the single claw. On the second pair of 

 legs we find one spur on the distal end of the trochanter, ten along the 

 inner edge of the femur with a stout one at the middle of the row, one 

 on a prominence on the tibia, two on the tarsus and one at the base of

 The third and longest pair of legs are (juite different from the others. 

 The large spurs are wanting, only the femur has its inner edge covered 

 with black spines. The end of the tarsus is covered with a brush of 

 thick hairs so that no claws can be distina;uished. The femur has a
