Ground color of body varying from luteous to dark castaneous, very 

 heavily marked with blackish fuscous, so that the latter is often or 

 perhaps generally the prevailing tint; the darker colors prevail always 

 on the hinder half of all the segments but the pronotum and some- 

 times, especially in young specimens, to such an extent that all parts 

 behind the pronotum are blackish fuscous, dotted with luteous ; in the 

 lightest colored specimens, the dark coloring prevails on the pronotum 

 along the anterior and especially the posterior margins, and is generally 

 present in a subdorsal posterior tongue emitted on either side from the 

 anterior margin ; the anterior edge of the dark posterior markings of 

 each segment, especially in the front portion of the body, is exceed- 

 ingly irregular and broken, and the lightest parts are more or less and 

 irregularly clouded with fuscous ; the femora are usually of the pre- 

 vailing tint of the body, but, even when the body is dark, are some- 

 times luteous throughout as the tibia? and tarsi always are, except for 

 occasional infuscation of the former at base ; the outer sides of the 

 hind femora have the characteristic markings of the genus more or less 

 distinct. Antennse moderately coarse at base, tapering with great 

 regularity, 3-4 times the length of the body. Legs very long and 

 slender. Fore femora no stouter than the middle femora, more than 

 half as long again as the pronotum, especially in the , distinctly less 

 than half as long as the fore femora, the inner carina usually with 2-3
