3. Spirostrejytus corcidus, sp. n. 



Head testaceous, with the front of the clypeus and labium 

 castaneous ; antennas reddish castaneous ; a broad bhackish 

 band connecting- the ocuhar plates ; nuchal plate blackish 

 brown, with whitish anterior margin ; dorsal segments with 

 a whitish central stripe, in front of which thej are dark 

 ochreous and behind it stramineous, excepting at the sides, 

 where there 'is a broad diffused brown longitudinal band; 

 along the centre of the dorsal region there is also a more 

 defined blackish band ; legs pale flesh-coloured. 



Body long, smooth, polislied, rather suddenly attenuated 

 towards the anal extremity : head rather large, almost circular 

 when viewed in front ; clypeus expanded at the sides, trun- 

 cated in front, without a central sutural line ; antennas with 

 long cylindrical joints, much as in the preceding species ; 

 ocular plates cuneiform, but with convex anterior margin, 

 next to which there are ten facets, whereas the posterior 

 margin only numbers from seven to eight ; nuchal plate 

 scarcely narrower at the sides than in the dorsal region, and 

 therefore terminating on each side in a regularly-arched lobe, 

 which is obliquely striated and has an indented line in front ; 

 dorsal segments tumid behind the middle line, longitudinally 

 striated at the sides ; preanal segment carinated along the 

 posterior margin, oblique at the sides, and very slightly 

 convex, terminating in a rather obtuse angle ; subanal plate 

 narrow, elongate-triangular, indented in front ; anal plates 

 compressed along the dorsal and posterior margins ; fifty-six 

 segments in all ; legs rather long and slender, slightly com- 

 pressed. 



Total length 26 millim., or about 1 inch ; width of nuchal 

 plate 2 millim., at centre of body 2:^ millim., of preanal seg- 

 ment 1^ millim. 



Fairly numerous, but not so much so as the two larger species. 



Dr. Karsch describes a species of Spirostreptus from N.E. 

 Madagascar in the ' Zeitschrift fiir die gesammten Naturwis- 

 senschaften ' for last year (p. 48), under the name of Spiro- 

 titreptus [Nodojiyge) olUgans ] and, notwithstanding the brevity 

 and imperfection of the description, which even fails to give 

 measurements, I am satisfied of its distinctness from any of 

 ' the species here described.
