the second and third segments contrasting in being of dark brown or 

 chestnut color wholly lacking the blue tinge. Legs brown or chestnut. 

 Antennae darker brown. Under the lens the collum shows the usual 

 light areolations as do the second and third tergites and the vertex of 

 head. The usual darker band between eyes enclosing two lighter spots 

 below at level of antennae. Clypeal region lighter. 



In the female the collum is narrowed down each side. In the male 

 it is much elongate as usual in Parajulus, with the lower margin on each 

 side long and straight. The middorsal length about equalling the com- 

 bined length of the next two and a half or three segments when not 

 coiled. Margined below and up the anterior corner but otherwise not 

 striate. Second tergite in the female extending below level of collum 

 with anterior edge lowest; but in the male the lower edge of the second 

 tergite is straight and on a level with that of the collum. 



Second tergite above lower edge with typically four longitudinal striae 

 and a shorter isolated one farther dorsad, this more pronounced on the 

 third tergite. On the following segments the number of striae increases, 

 the series extending halfway up the side but not attaining the level of 

 the pore by a considerable space. These longitudinal striae deep, cross- 

 ing only the metazonite. On the prozonite in front of them are 

 fewer striae, similarly pronounced, which curve dorsad and cross the dor- 

 sum as transverse striae normally mostly covered by the preceding meta- 

 zonite in each case. Segmental suture strongly marked, conspicuously 

 angled at level of pore which lies in line with its straight portion. 



Anal tergite acutely produced beyond the valves behind, the cauda 

 straight. Anal valves not margined. 



Legs in general rather long and slender. 



In the male the first legs are enlarged and strongly crassate, the meta- 

 tarsus long and straight, flattened beneath. Second legs of the male re- 

 duced ; the coxae enlarged and produced forward in a slender, linguiform, 

 straight process which extends to the gnathochilarium, slightly narrowing 

 distad. 



Cardo of mandibles in the male strongly produced ventrad, the process 

 subacute below, attaining level of edge of labrum. 



The gonopods have the general configuration of those of E. amphelictus. 

 First branch of anterior pair of ordinary texture, narrowly ovate above 

 the constricted base, strongly setose. Second branch strongly chitinous 

 and smooth, a broad thin plate at base abruptly narrowing into a slender 

 blade which extends ventrad with weakly sigmoidal or sinuous flexure, 

 distally bending abruptly mesad and then caudad; without processes or 

 spurs. The posterior gonopods are broad blades curving forward in con- 

 tact with body, then ventrad and finally at ends mesad toward each 

 other; secondary spur or blade of each extending straight ventrad, slender 

 and acute, long, much as in amphelictus. 



Number of segments, fifty-four (male type). 



Length about 45 mm.; width, 2.8 mm.
