 ■\- =;: :;: J)reviti'7' dfntatis'^ {femorata). 



Femorata is quite distinct from armuta^ the chief differences 

 being the form of the elytra and the femoral teeth — both very varia- 

 ble characters. 



General observations. — The mentum is subparabolic. In one speci- 

 men it is snbtrapezoidal ; surface scarcely convex and not foveate 

 laterally. 



The prosternum in the spechnens at hand is arcuately rounded 

 antero-posteriorly, with a small and abruptly developed mucro be- 

 hind, which may be horizontal or deflfexecl. Mesosterniim as ii» 

 armata. 



The abdominal process is subquadrate, feebly transverse; the post- 

 coxal portion of the first segment is equal to the second in length; 

 the third is as long as the width of the metasternal salient; the fourth 

 is about one-half as long as the second. 



The intercoxal process of the abdomen is about a fourth wider than 

 the metasternal salient. 



The metasternum laterally between the coxae is as long as the width 

 of a mesotibia at apex. 



The tibial grooves of the femora are well developed and distinctly 

 defined; their floors are opaque and quite plane. Those of the pro- 

 femora ai'e subentire, those of the meso- and meta femora nearly 

 attain the femoral base, and the carinate margins are somewhat eva- 

 nescent internally. The anterior margin of each groove is more or 

 less dentately laminate externally. 



The protibise are somewhat compressed and distinctly carinate 

 external!}^; their tarsal grooves are more or less developed, opaque, 

 and asperately sculptured. The articular cavities are more or less 

 open. 



The mesotibise are carinate externally in basal third; the grooves 

 are more or less indicated, opaque, and muricate. The articular cavi- 

 ties closed. 



The metatibise are more or less finely subcarinate externally, and 

 the grooves are scarcely evident, muricately sculptured; articular 

 cavities closed. Both the meso- and metatibise are slightly com- 

 pressed. 



Tarsi moderate in length and rather stout. The protarsi are about 

 a sixth of their length shorter than a mesotarsus. Joints one to four, 

 inclusive, subequal and a little wider than long; joints two to four 

 combined equal in length to the fifth. 



The mesotarsi are about a seventh of their length shorter than a 

 metatarsus. Joints tw^o to four inclusive subequal and very little
