Coloration. — Male much as in hispidus; blackish olivaceous above, with a 

 yellowish stripe on each side, interrupted at the first pronotal sulcus and some- 

 times at the intersections of the abdominal segments, running from the dorso- 

 caudal portion of the eyes, along the dorsum of the pronotum just above the 

 lateral lobes and along the abdomen to the last segments. The width and 

 intensity of these bands shows some individual variation. Face and lower 

 half of lateral lobes of pronotum yellowish. A blackish olivaceous band on 

 each side starts from mesad on the caudal margin of the eye, occupies the 

 dorsal half of the lateral lobes, expanding caudal on the metazonal portion, 

 and is continued thence on the lateral portions of the abdomen, narrowing 

 gradually distad. Underparts yellowish. Limbs reddish brown, the caudal 

 femora showing three weakly defined, transverse suffusions of darker brown 

 and a pregenicular pale area, which is weakly indicated on the caudal tibiae 

 in the portion adjacent. 



:» Female similar in general coloration, but much less brilliant. Reddish 

 brown above, with paler bands represented only by a somewhat paler suffusion 

 margining the dark lateral bands dorsad. Caudal limbs with markings even 

 weaker.
