tiuge ; the markings consist of a mediodorsal stripe of varying width 

 but usually rather broad on the prouotum, especially a little before 

 either border, generally reduced to a line on the abdomen, a large 

 lateral patch on either side of the pronotum, sometimes confined to the 

 inferior margin, sometimes extending half way to the mediodorsal line, 

 and a conspicuous and liberal sprinkling of roundish 'spots, generally 

 more or less elongated longitudinally, especially on the abdomen ; the 

 antennae are pale fuscous and the legs sordid luteous more or less 

 infuscated, the hind femora with heavy fuscous scalariform markings, 

 leaving roundish dull luteous spots in the openings of the upper half. 

 The antennae are slender and apparently only about twice the length 

 of the body or a little more, and the legs short though slender. Fore 

 femora of the same slenderness as the middle femora, much less than 

 half as long as the hind femora and a little more (<J) or a little 

 less (9) than a fourth longer than the pronotum, the inner carina with 

 1-2 small spines. Middle femora with 13 spines on the front carina, 

 the subapical the longest but not long, the hind carina with rarely 

 more than the moderately short genicular spine. Hind femora some- 

 what shorter than the body, about two and a half times longer than 

 the fore femora, moderately slender, being about three and a third 

 times as long as broad, fully the apical fourth subequal, the surface 

 with no raised spines, the outer carina with a few distant serrations 

 or recumbent spines on apical half (<) or unarmed (9), the inner 

 carina similar to the outer, the intervening sulcus narrow. Hind 

 tibiae straight in both sexes, not a great deal longer than the femora, 

 armed beneath with a single subapical spine besides the apical pair ; 

 spurs subalternate, the Sasal at the end of the proximal third of the 

 tibia, scarcely if any longer than the tibial depth, set at an angle of 45 

 with the tibia and divaricating about 110, their tips incurved ; inner 

 middle calcaria much longer than the outer, more than twice as long 

 as the others or as the spurs, and nearly as long as the first joint of 

 the tarsus. Hind tarsi fully two fifths as long as the tibiae, the first 

 joint almost as long as the rest together, the second twice as long as 

 the third and with it fully as long as the fourth. Cerci slender, taper- 

 ing regularly, three fourths as long as the femoral breadth. Ovipositor 

 as long as the fore femora, straight, the apical three fifths equal and 

 moderately slender, the apex a little upturned and subacute but not 

 very much produced, the teeth of the inner valves consisting of blunt 

 pointed crenations.
