with a median black spot ; tlie following tergites in the 

 anterior iialt" of tiie body similarly coloured, but tlie dorsal 

 red marks gradually lose their distinctness, becoming first 

 brown, then bh-xck ; anal somite deep black-brown. 



Head smooth and siiining, the sulcus distinct below ; labral 

 pores obsolete. Ei/es separated by a space that is about equal 

 to a diameter and a half. Antennai long, much longer than 

 the head. 



First tergite projecting inferiorly almost as low as the 

 second, acutely angled, with marginal sulcus, but without 

 other sulci. The rest of the tergites with the posterior portion 

 higher than the anterior, the transverse sulcus complete, the 

 upj)er surface in front of the sulcus and behind it smooth and 

 polished, the lateral surface thickly and longitudinally striate 

 below, the striai gradually disappearing above and taking a 

 vertical direction on the anterior part of the tergite ; sterna 

 and inferior ])ortion of anterior surface transversely striolate j 

 pores conspicuous, above the middle of the side, in front of the 

 sulcus. Anal somite nearly smooth, tergite acutely angled 

 behind, covering the summit of the valves ; valves prominent, 

 the borders strongly convex, almost the posterior half com- 

 pi'cssed ; the sternite large, distinct, and triangular, its angle 

 nearly a right angle. 



Legs long, with a single seta beneath each segment, ter- 

 minal segment padded. 



Copulatory feet very wide (see fig. 2 h). 



Length about 146 millim., width 10. 



Number of somites 52. 



Lac. N. Madagascar [Rev. R. Baron). 



Closely allied to Sp. Coicani (Butler), from Betsileo. In 

 Cowani, liowever, the anal somite is blood-red, and there is 

 a wide flesh-coloured band along the dorsal surface of the 

 somites. The somites, too, are not so elevated behind and 

 are finely striolate. 



Spirobolus urojjhorus, sp. n. (PI. XVI. figs. 3, 3 a.) 

 Colour. Head and legs flavous ; posterior half and inferior 

 portion of somites also flavous ; anterior half fuscous ; a 

 median dorsal flavous band more conspicuous posteriorly. 

 Antennaj infuscate. 



Bodg moderately robust, much narrowed posteriorly. 

 Head smooth, sulcate and striolate above, with two pores on 

 each side of the labrum. Antennce a little longer than the head, 

 the segments, except the first and last,subequal in length. The 

 greatest diameter of the eyes is from above downwards ; the 

 distance between them much less than twice this diameter. 

 The collum not projecting so low laterally as the second 

 somite, narrowed laterally, with marginal sulcus, the angle
