96 PECKHAM. [Vol. 2, 



This is a very showy spider. The females and immature 

 males have the cephalothorax black, covered with red hairs and 

 silver scales ; no distinct j)attern can be made out in our speci- 

 mens, which are all more or less rubbed. The abdomen is red, 

 with a wide, silver band around the anterior end and sides, and 

 a silver band with indented edges down the middle. On each 

 side, extending upward from the encircling band, are two 

 oblique, silver bars. The on\j adult male in our collection is 

 black, with patches of silver scales on the cephalothorax, and 

 on the abdomen four or five transverse, silver bands, which 

 become chevrons in the posterior part. These silver scales are 

 highly iridescent, showing green, blue and red tints. The legs 

 are dark, with silver patches, the first pair being the darkest. 



From Chapoda, Brazil, in the Smith collection. 



In this species the thorax widens out more perceptibly in 

 the male than in the female, while in Epinga ornata the dila- 

 tation is much plainer in the female.

 This is a large, heavy spider. 

 The quadrangle of the eyes is one-sixth wider than long, is 

 almost equally wide in front and behind, and occupies two- 

 fifths of the cephalothorax. The cephalothorax widens out 

 considerably in the thoracic part. The sternum is long ; the 

 anterior coxse are almost touching. The labium is longer than 

 wide. The abdomen is large and rounded, more like Bavia 

 than Marptusa. 



The cephalothorax is dark brown. The cephalic plate is 

 black with green and purple reflections. The middle of the 

 abdomen is of a rather bright olive-green with a few iridescent 

 scales — all that are left of the original covering. On each 

 side is a longitudinal, brilliant red band, and, below this, a
