 (1894). 



Dull luteo- or rufo-testaceous, very heavily flecked with dark fuscous 

 so as to produce a tolerably uniform mottled appearance, ordinaril}' a 

 little more open than elsewhere in a narrow mediodorsal streak on the 

 pronotum, and in the tolerably clear luteous or pallid luteous of the 

 inferior margin of the descending thoracic lobes ; the flecking is made 

 up of small more or less confluent dots, which assume a certain longi- 

 tudinal regularity on the abdomen only ; legs varying from luteous to 

 testaceous, more or less infuscated, especially on the apical portions of 

 the femora and in the distinct and heavy scalariform markings of the 

 hind femora. The antennae are moderately stout in the basal, but in 

 the apical half very slender, apparently only a little more than twice the 

 length of the body, the legs moderately long. Fore femora no stouter 

 than the hind femora, much less than half as long as the hind femora, 

 but considerably more than a third longer than the pronotum in the $ 

 though only a fourth longer in the 9 , the inner carina with 2-3 spines, 

 the subapical not much longer than the others. Middle femora with 

 the front carina as in the fore femora, the hind carina armed with 1-3 

 spines besides a moderately long genicular spine. Hind femora 

 longer (^$) or shorter (9 ) than the body, considerably more than twice 

 as long as the fore femora (at least a third more in the male), stout, the 

 apical third or fourth subequal, about three and a third times as long 

 as broad in the male, the darker portions of the surface of the apical 

 half of the femora and the upper portion of the inner side rather 

 heavily {$) or very sparsely (9) scabrous with raised points, the 

 outer carina armed with 7-8 unetjual inequidistant coarse irregular ar- 

 cuate spines, the largest (just beyond the middle) as long as but much 

 stouter than the tibial spurs (<?) or almost entirely unarmed but for 

 some 3-4 raised points ( 9 ), the inner carina with about sixteen small 

 inequidistant coarse spinules covering the whole length {$) or a few 

 slight ones only on the apical fourth of the femora (9), the interven-
