The nietastermiin laterally between the coxae is about as long as the 

 width of a metatibia at middle. 



The profemora are very feebl}^ swollen in external half; this condi- 

 tion is A'ery gradually attained from the base; the surface lines are 

 very feelily arcuate when viewed lengthwise; the tibial grooves are 

 moderate in width, with margins rather course and slightly arcuate, 

 becoming evanescent a little distance from the base but not contigu- 

 ous at point of evanescence; floors feebl}^ concave, opaque, and more 

 or less minutely. reticulate. 



Meso- and metafemora almost subequal in width throughout wdien 

 taken individually, each having the corresponding sides subparallel. 

 The grooves of the mesofemora are a little narrower than the pro- 

 femoral, the margins ai'e coarse and subgranulate, evanescent at in- 

 ternal third; floors feebly concave, smooth and opacpie, more or less 

 rugulose, sometimes transversely so. 



Metafemoral grooves a little narrower than the mesofemoral and 

 very feebly concave; margins coarse, more or less granulate, the 

 posterior frequents finely serrulate, both evanescent a little internal 

 to the middle. 



The tibiae are usually quite stout and usually more or less feebly 

 arcuate. The protibiae are scarcely compressed and more or less 

 carinate externally ; the tarsal grooves are more or less developed and 

 asperate; the articular cavities are more or less closed. 



The mesotibiae are somewhat circular in section, usually not at all 

 carinate externally; grooves more or less developed, rather narrow, 

 opaque and limited by the general muricate sculpturing. 



The metatibiae are quite cylindrical in section, otherwise like the 

 mesotibia\ The articular cavities are closed in each. 



The tarsi are stout and moderate in length. 



The protarsi are about a fourth of their length shorter than a 

 mesotarsus. Joints 2^ subequal in length and apparently decreasing 

 in width in the order named, a little wider than long and together 

 about equal in length to the fifth ; first joint a little longer than wnde. 



The mesotarsi are about equal to a metatarsus in length. Joints 

 2^, inclusive, subequal in length and very slightly decreasing in size 

 in the order named, and together subequal in length to the fifth; the 

 first about twice as long as wide. 



The metatarsi are about half as long as their respective metatibia. 

 Joints 2 and Ji slightly decreasing in length, width, and size in the 

 order named, each distinctly a little longer than wide, together 

 scarcely as long as the fourth and quite as long as the first.
