CHAlfBEBUN: MviiloroDA OF TBS aistuai.ian REGION. 165 



Agrees with E. kaortntu and differs from fasciatus and distinctior in 

 having a series of stout spines or pectinae al distoectal corner of coxa! 

 piece of the anterior gonopods. Unlike K. Icaorin us, these pectinae 

 not borne on a distinct shoulder or lobe, there being a small distoectal 



process apart from the pectinae; spines much smaller than in kaorinus 

 and not exceeding the series of spines across apex of t.elopoditc in size 

 The inner distal process distally rounded, only slightly curved. 

 Clearly differing from K. kaorinus also in the form of the anterior 

 median plate, this in the present species being distally rounded and 

 mesally only vaguely indented, not deeply angularly excavated. 



Number of segments, thirty-six to forty-two. 



Diameter (male), 2.1 mm. Short. 



445. Eumastigonus maior, sp. nov. 



Type.— M. C. Z. 4,876. New Zealand: Day's Bay, near Welling- 

 ton (W. M. Wheeler). 



Having the usual pattern of coloration as exhibited in E. kaorinus 

 and distinctior. The light annuli ferruginous except a narrow margi- 

 nal stripe across dorsum which is fulvous. A series of small light 

 spots just above the pores and below toward ventral surface a series 

 of larger light spots with above each on prozonite a narrow vertical 

 light stripe. Collum mostly ferruginous with vague network of dark 

 lines; anterior border black, the black band widening toward middle 

 where it is connected by two black lines with a triangular black caudal 

 area embracing two light spots. Head with usual color-pattern. 

 Anal scutum black, valves light. Preceding segment also light. 

 Legs light ferruginous. 



Most readily differentiated by means of the sculpturing of the 

 tergites. On these the metazonites are closely longitudinally striate 

 below, the striae on passing to the prozonite curving and running 

 directly dorsad, the prozonites thus covered below with vertical, 

 slightly wavy, and mostly continuous lines which on the anterior 

 part are conspicuous up to the level of the pores. In the anterior 

 region of the body the striae of the prozonites become more oblique 

 and shorter. 



Eyes rather small. Composed of only three transverse series of 

 ocelli. 



(Ollum smooth and shining. Narrowly margined below as usual. 

 With a stria or sulcus nearly longitudinal, not paralleling the antero-
