 Eyes arranged in three groups of 2, 4, 2, front median pair rather small, and 

 separated from each other liy a si)ace equal to once their individual diameter; 

 rear median pair large, seated well back, and separated from each other by a 

 space equal to fully twice their own individual diameter; side eyes small, 

 contiguous, and placed at the extremity.' of lateral angles. Legs short, strong, 

 yellow, anntilated, moderately hairy, tibiae and metatarsi i and ii armed on 

 their inner angles with long, strong spines. Relative lengths, 1. 2. 4, 3. 

 Palpi short, stout, yellow, moderately hair}-, and armed with a few small,

 it retreats inwards, and terminates in a somewhat acute jmint ; immediately 

 in front of each lateral terminal tubercle there is a small yellow nodule:
