ment and caudal rami colorless; front half of head whitish from

 corneal lenses well separated and en- 

 tirely visible on the frontal margin ; 

 first three segments as wide as the 

 head, fourth segment slightly nar- 

 rower, with a rounded projection on 

 the dorsal midline at the posterior 

 margin; caudal rami two-thirds 

 longer than wide. Fourth segment 

 of second antenna considerably long- 

 er than the third segment, the two 

 together two-thirds as long as second 

 segment; endopod of fourth leg 

 shorter than exopod, its two apical 

 setae very large and equal. Total 

 length, 1.9-2.15 mm. 



Male. — Unknown.

Color.— Th% body of the female is colorless and transparent, with 

 bright-red spots scattered over the dorsal surface near the lateral 

 margins; these show no definite arrangement, and vary in size, but 

 are all fairly circular in outline. The male is brilliantly iridescent, 

 except the fifth thoracic segment, the anal segment, and the caudal 

 rami; the dorsal surface is reticulated, the meshes of the network 

 more or less angular. The yellows predominate along the margins 

 and the reds through the center of the metasome, while the center
