706 MYRIAPODA FROM AFRICA COOK. 



verse diameter of one of tb»in; ocelli snbequal, arranged ll + 10-f-0-|-8 

 + 7 + 5 + 3=53. 



Antennie 4 mm. long, the fifth aud sixth Joints together longer than 

 the second. 



Mandibnlary stipe with anterior edge of exi)osed snrface broadly 

 emarginatc, 



Mentum oblong, about six times as broad as its median length, pos- 

 terior corners rounded in the female, in the male replaced by a mem- 

 branous i)ouch into which fits the large process of the copa of the first 

 pair of legs. 



Promentum without bristles. 



Siipe of gnathochilarium with scattered bristles along the promentum 

 and the anterior half of the lateral margins. 



Lingual lamime with a few short bristles at base, and three long ones 

 toward the anterior margin. 



First segment smooth, anterior angle rounded; one complete and 

 deep striation, and a branched, more shallow, marginal striation. 



Anterior subsegments Avith seven or eiglit concentric striations on the 

 anterior portion, the striations with small protuberances about as far 

 apart as the striations are from each other; some of the protuberances 

 not on the striations, but located without regularity on that part of the 

 subsequent which is behind the striations. 



Posterior subsegments with fine curved and branching wrinkles 

 whose general direction is longitudiiuil; the coarser striations of the 

 sides and inferior surface begin about two-thirds of the distance from 

 the median line to the repugnatorial pore, but the striations above the 

 pore are very short and to be found only along the suture. 



Supplementary margin finely and equally pectinate, 0.055 mm. long, 

 including the teeth, which are 0.01 mm. long, broad at base, pointed; 

 sinews between teeth rounded, 0.01 mm. broad. 



Kepugnatorial i)ores longitudinally elliptic, 0.04 mm. long, situated 

 at the middle line of side, nearer to the nearly straight suture than to 

 the posterior margin of the segment, lu front of the pore the surfiice 

 of the segment is smoother, and immediately behind the pore is a more 

 or less evident depression. On male specimens the fourth segment 

 from the end may have no pores. Sometimes there is a ])ore on one 

 side and not on the other. 



Last segment rugose above, smoother below and finely punctate, 

 strongly carinate on the median line above; posterior angle somewhat 

 produced, rounded. 



Anal valves rugulose-punctate, each with a prominent carina which 

 incloses a crescentic space between it and the moderately prominent, 

 slightly compressed margins ; the carina is produced above into a large, 

 usually sharp-pointi'd mucro, curved slightly cei>lialad at apex. 



I're-aiial scale punctate, rounded, nearly twice as broad as long. 



First pair of legs with the process of coxa tuberculate- wrinkled, a
