Dekana, nov. gen. 



Dehana, allied to Chenistonia by the ahnost unique position of 

 the tibial palj)al spui- of the male, differs fi'om the latter in having 

 the thoracic fovea piocurved and the posterior sternal sigilla 

 rather large and I'emoved from the margin by a distance equal to 

 that from the median line. 



Type species, D. diver sicolo7: 



Dekana diversicolor, nov, sp. (Text-fig. 27.) 



Male. Cephalothorax dark I'ed-biown, mandibles black-brown, 

 shoit fine downlying hair silvery white, and upstanding longer 

 brown. Lip, maxillpe, sternum, and coxse pale chestnut. Legs 

 and palpi red-brown, lightening towards the extremities, scopulse 

 greyish yellow. Abdomen black above and underneath. Front 

 abdominal shield, gill-covers, and spinnerets yellow, hairing silver- 

 grey above, yellow on sides and underneath. 



The cephalothorax is 2 millimetres longer than broad, rounded 

 at sides, broadly truncate in front, somewhat narrower at rear 

 end, which is concave. The cephalic part is only moderately 

 raised up, the highest part being about the middle behind the 

 eyes, which are situated on a well-developed oval prominence 

 rising abruptly from almost the margin of the clypeus. The 

 front middle eyes, green, the remainder being yellow, are three- 

 fourths of their diameter apart and half that distance fiom the 

 nearest point of the laterals which are 1^ their diameter. These 

 are set in a plane perpendicular to the cephalic surface, and being 

 at the lower part of the prominence make the row, which is 

 straight seen from above, rather strongly piocurved from in front.
