Rainbow — Arachnida 243 



similar. Eyes as in the male. Legs long', yellow, tapering, hairy, armed with 

 short fine spines. Relative lengths, 1, 4. 2, 3. Palpi short, similar in colour 

 and armature to foregoing. Falces, maxillae, labium and sternum as in the 

 male. Al^domen ovate, arched, slightly overhanging base of cephalothorax, 

 j-ellow, pubescent : superior surface ornamented with white and fuscous 

 patches; sides and inferior sin'face ^■ellow. Epigynum slightly raised, oval, 

 and having two large circular discs ; the latter ringed with black, and situated 

 close together. 



Three examples of this species were collected — two males and one female. 

 One of the former has lost its anterior pair of legs. Judging by the specimens 

 before me the male at any rate is \arial)le in its abdominal decoration. In one 

 example there is a large and prominent black patch at the posterior extremity 

 of the abdomen, while in the other it is absent, and has in its place a broken, 

 wavy transverse bar. The outstanding feature in the perfect male is the 

 greatly developed femora of the first pair of legs. Tvpe, I. 11521.
