Cephalic segment cordate, depressed ; basilar segment large ; mandibular tooth with a very 

 distinct tubercle at its base ; labium smooth, with a triangular depression between the 

 dental plates ; dental plates quadrate, elongate, with the anterior margin rounded ; teeth 

 eight, distinct, but obtuse. Posterior pair of legs with the basilar joint narrow, equal, 

 elongated, with the superior surface flattened and the external margin with a very slight 

 elevated border; internal margin with five or six minute slightly hooked spines, the 

 four anterior of which are sub-approximated, and arranged in two parallel series ; angu- 

 lar spine large, quinquefid. Internal and inferior surfaces rounded, with nine spines 

 arranged in three slightly diverging alternating longitudinal series, three in each series, 

 the posterior spine of the internal series on the internal surface. Second joint elon- 

 gated, flattened and slightly margined. Lateral anal appendages obtuse, minutely 

 punctured, with the apex pointed and bifid. Preanal scale cordate, quadrate, with the 

 posterior margin straight. 



This species also greatly resembles S. Leachii, but is quite distinct from it. 

 The basilar joint of the posterior legs is much narrower than in that species, 

 and the disposition of the spines on the under surface of the joint is different.

Cephalic segment cordate, flattened ; antennas red, darker at the extremities ; basilar seg- 

 ment moderate ; mandibular tooth large ; labium flat, narrower anteriorly, sutures ab- 

 sent ; dental plates almost quadrate, with the margin rounded ; teeth ten, short, obtuse. 

 Posterior pair of legs with the basilar joint slender, with the superior surface flattened ; 

 the external margin acute and the internal one with five spines, the four posterior of 

 which are arranged in two alternating series, not approximated ; the apical one elon- 

 gated, quadrifid ; the inferior surface rounded, with nine spines in three series, three in 

 each series, forming transversely three oblique rows, the distal spine of the internal 

 series situated on the internal inferior border. Lateral anal appendages narrowed and
