sides lighter than the dorsum, finely mottled with buff and brown ;

 extending from just behind the lung books to the spinnerets, the 

 region of the genital orifice deep brown, the lung books yellow. 

 Chelicera aln»ost black, with a pale prominence at the supero -lateral 

 angle, and covered anteriorly with both black and yellow hairs. 

 Labium black proximally, yellow distally; maxillce yellowish.

Comparisons. — This species differs from j:)»rce/^t n. sp., frondicola 

 Emerton, and kochii (Keyserling), to all of which it shows resem- 

 blances, in the posterior eyes being the largest, in the propor- 

 tionately and absolutely lai'ger size of the palpal organ, and in the 

 black stripes on the cephalothorax.

 slightly higher than the middle, the middle eyes approximated.
