 narrow middle-stripe, which most eommonly reaches from the 

 hind-edge nearly to the posterior eyes. On the sides of the 

 pars thoracica is a more or less distinct blackish band (the 

 margins are påle testaceous). The eyes are surrounded by 

 black rings. The cephalothorax is miich shorter than the

 as long as their radins and the distance from the lateral 

 eyes more than twice as long. The two lateral eyes are 

 contiguous, and little prominent. The hind-row is slightly 

 recurved; the middle-eyes, which are much larger than the 

 other ej^es, are situated on large black tiimnli and separated 

 from each other hy an interval twice as long as their dia- 

 meter and a little longer than the distance from the lateral 

 ones. The area of the middle-eyes more broad than long, 

 much narrower in front.
