Type.— M. C. Z. 4,761. Fijis: Suva (W. M. Mann). 



The general color is brown of a ferruginous tinge with a broad dense black 

 band along each side of the dorsum; the hght dorsal band embraced between 

 the two black stripes includes at its outer edge on each side a longitudinal 

 series of lighter fulvous spots, one on the prozonite of each segment. Legs 

 light ferruginous. Anal scutum black excepting a narrow pale caudal border 

 and a ferruginous spot above into the middle part of which the black extends 

 back in an angular tongue. 



Sulcus weak or absent in the frontal region. Foveolae 2+2. 



Collum not attaining lower edge of the second tergite. Surface densely 

 covered with fine impressed points and lightly impressed short striae, the 

 surface to the naked eye appearing smooth and shining. 



The surface of the other segments also marked with numerous fine puncta 

 and more weakly impressed short lines. Covered zone of segments smooth 

 or nearly so. In front of sulcus above level of pore on each side a series of 

 well-separated obUque striae the most dorsal of which run transversely parallel 

 to the segmental sulcus or suture with sometimes one or more others in front 

 of it, below pore the longitudinal striae evident in front of suture over the entire 

 side but caudad of it they occur only lower down. The suture distinct, 

 angled at level of pore. Scobina extending to segment twenty-four or twenty- 

 five. 



Anal segment with surface like that of the others. Valves exceeding the 

 scutum.

 and also with a short submarginal sulcus at the anterior corner detached from 

 the lower margining sulcus. Surface smooth and shining. 



Anterior covered border of segments finely vertically striate. On some 

 anterior segments also with some transverse striae exposed in front of the 

 suture, these striae wavy and discontinuous. Suture distinct on the sixth
