 strikinjfly contrasted colors, the ^rcen of whi<'h is deeper and of a 

 bhicr tint and the femora are stouter. The face is yellow with a slight 

 l^iTeenish tint, coarsely and distinctly punctate with blackish l)rown; 

 the intercostal interspace below the antennae is heavily infuscated 

 and the usual short bar below the eyes is present; vertex yellow, the 

 fasti;iiuni heavily infuscated and behind it a wideninj*' blackish stripe, 

 posteriorly inclosing a median yellow thread; antennae fuscous, the 

 joints feebly and narrowly annulate with pale ferruginous. Pronotuuj 

 yellow, more or less olivaceous, and on the metazona often heavily suf- 

 fused with bright ferruginous, all the transverse sulci ami i>articularly 

 that close to the front margin heavily marked in black, which cuts the 

 heavy black-bordered mediodorsal yeHow stripe; upper portion of the 

 lateral lobes more or less heavily marked with black on the prozona; 

 pleural sutures heavily marked in black. Tegmina of about the length 

 of the abdomen, bluish green, the discoidal and posterior ulnar veins 

 with a narrow pallid yellow stripe. Fore and middle femora duU ferru- 

 ginous; hind femora with the outer face dull greenish luteous, the 

 sui)erior carina heavily flecked an<l punctate with fuscous, and a faint, 

 broad, dull coral red, pregenicular annulation; hind tibiae greenish 

 blue, the spines white with black tips, the tarsi more or less testaceous. 

 Sui)raaual plate of male much as in //. festivKs, the furcula consisting 

 of a pair of minute but boldly projecting rounded lobes, separated by 

 twice their own width; cerci slightly compressed, subconical, tapering 

 much more rapidly in the proximal than in the distal half, the latter 

 being nearly equal, the tip rounded but slightly produced and gently 

 incurved, the whole scarcely so long as the supraanal plate; infracercal 

 plates incons])icuous, apically tapering, almost as long as the sui>raanal 

 plate. 



Length of body, male, 21 mm., female, 26 mm. ; antennae, male. S mm., 

 leniale, 7.75 mm. ; tegmina, male, 15.5 mm., female, 20 mm. ; hind femora,
