The abdominal process is siibquadrate and slightly transverse, 

 its width is equal to the length of the third segment ; the post-coxal 

 part of the first segment is subequal in length to the third, the latter 

 is one-third of its length shorter than the second; the fourth is a 

 little more than one-half as long as the second. 



The abdominal intercoxal salient is one-fifth of its width greater 

 than that of the metasternal process. 



The tibial grooves on all of the femora are quite strongly mar- 

 gined, distinctly concave and glabrous; the margins are subasperate 

 and converge gradually to the femoral bases. 



The anterior margins of the profemoral grooves are quite dis- 

 tinctly carinate and not very strongly dentately laminate at about 

 the outer sixth, thence more or less obsolete to apex. 



The external borders of the protibise are more or less subcarinate, 

 those of the meso- and metatibise are rounded, muricately sculp- 

 tured, and not in the least carinate. 



The jDrotibia' are slightly compressed, the others subcylindrical. 

 The tarsal grooves are more or less indicated on all of the tibiae, but 

 most marked on the anterior. These grooves are all asperately 

 sculptured. On the protibia^ the more or less developed carina? pass 

 to the outer margin of the tarsal grooves, while the internal margins 

 are more or less serrulate. 



The anterior surfaces of the protibise are feebly subasperately 

 sculptured, and the posterior surfaces are strongly asperate. 



Tarsi somewhat slender and moderate in length. 



The protarsi are about one-third of their length shorter than a 

 mesotarsus. Joints 1 to 4, inclusive, are small, short, and slightly 

 transverse; the first slightly the thickest and longest, the second, 

 third, and fourth subequal in length. 



A mesotarsus is equal in length to a metatarsus. Joint one slightly 

 shorter than the third and fourth taken together; the second, third, 

 and fourth subequal, short, and scarcely longer than wide; second 

 slightly the longest. 



A metatarsus is about one-third of its length shorter tlian its meta- 

 tibia. Joint one equal to the next two taken together; second and 

 third subequal in length.
