CYCLOPOIDEA. H59 



Length, one-twelfth of an inch. Colour, blue, with the abdomen wine- 

 yellow and yellowish carmine ; base of caudal setge, wine-yellow. The 

 head is shorter than broad. The pigment of the inferior eyes in a ver- 

 tical view appears just behind the superior eyes. The caudal stylets are 

 short; the length not twice the breadth. The large joint in the right 

 male antenna is scarcely twice as long as broad; it is prominently 

 convex on the anterior side, and angled on the posterior side near 

 base ; the next joint is oblong terete, with the margin minutely pecti- 

 nate; the following joint shorter and more slender. 



The right posterior foot has the second joint oblong, subterete ; the 

 third stout suboval, with a stout spine as long as second joint, pro- 

 ceeding from one side near base ; the fourth a finger nearly straight, 

 as long as the third, and having one or two minute spines on the 

 inner margin. The segments of the abdomen are transverse, and the 

 third had a process on the right side. 



This species resembles the preceding, but differs widely in the size 

 of its inferior eyes, its shorter caudal stylets, the posterior feet, &c.

Male: — Stout. Front rounded. Cephalothorax five- to six-jointed, 

 posterior angles long acute and remote, head separate, posterior 

 segments three. Superior eyes remote, inferior rather small. An- 

 terior antennse shorter than the body, diverging less than 60°, near 

 middle very slightly bent and then diverging about 70°; setae short, 

 anterior apical longer than the joint, posterior penult a little shorter, 

 other apical short, other subapical very short. Right antenna 

 very nearly as in the P. strenua. Longer branch of posterior an-
