Ill the male the second segment is a little longer than the jjost-coxal 

 part of the first and twice as long as the fourth. The third is about 

 one-half longer than the fourth. 



In the female the second segment is about two and one-half times 

 longer than the fourth. 



The profemora are rather feebly and evenly tumid, scarcely clavate; 

 the grooves have Avell-defined subasperulate margins that become 

 contiguous at basal fourth. . 



The meso- and meta femora are scarcely at all widened externally. 

 The superior and inferior surface lines are quite parallel. The tibial 

 grooves of the mesofemora are quite well defined by asperulate mar- 

 gins that become evanescent before becoming contiguous. On the 

 metafemora the grooves are similar, but evanescent at middle. 



In the typical form the tibia) are rather slender, and stouter in the 

 other forms. The tarsal grooves are obsolete and the articular cavi- 

 ties closed. The tibiae are usually not at all arcuate. 



The tarsi are moderate in length and stoutness. 



The protarsi in the male are apparently a little longer than in the 

 female ; about two-sevenths of their length shorter than a mesotarsus. 

 Joints two, three, and four are subequal, and together about equal to 

 the fifth : the first is scarcely as long as the second and third taken 

 together. 



The mesotarsi are about a fifth of their length shorter than a meta- 

 tarsus. Joints two, three, and four slightly decrease in length in the 

 order named, and together a little longer than the fifth ; the first is 

 quite equal to the combined lengths of the second and third. 



The metatarsi are about five-eighths of their length shorter than a 

 metatibia. Joints two and three are subequal, and together equal to 

 the first, the fourth being slightly shorter.

Rather robust and convex, somewhat strongly shining, intense black 

 throughout. Head scarcely twace as Avide as long, feebly convex, 

 rather broadly and more or less impressed laterally, frontal suture 

 usually distinct, bisinuate, and more or less impressed, coarsely and 

 rather closely punctate; punctures sparser on the vertex, rather 

 coarser on the epistoma. Antennm subequal in length to the head and 

 prothorax. the third joint three times as long as wide and rather 

 longer than the next two combined ; the outer joints but moderately 

 robust. 



Pronotum from one-fouvth to three-fifths Avider than long, and 

 Avidest a little before the middle; disc moderately and evenly couA^ex, 

 arcuately declivous at the sides, rather coarsely, deeply punctate,
