before the middle begins the secondary whorl on the lower 

 margin, and on the distal third of the antenna it is developed 

 on the upper margin ; the sette of this whorl are only a little 

 shorter than those in the central one. 



Scuta. — They differ only in some rather small particulars 

 from those of S. neotropica. The second scutum (fig. o a) 

 with the processes rather large, as broad as or a little broader 

 than long, in large specimens with three, in small specimens 

 with two seise along each margin, and the distal seta near 

 the apex. The distance between the processes a little or 

 rather considerably shorter than their length. The antero- 

 lateral setae as long as or a little shorter than the processes; 

 the lateral setae somewhat shorter than in S. neotropica, 

 but yet some of them of considerable length. The third scu- 

 tum (fig. 3 a) with the processes rather lai-ge and somewhat 

 broader than long ; the distance between them somewhat or 

 considerably longer than their length ; the setre nearly as in 

 the second scutum. 



Legs. — The last pair (fig. 3 h) agree as to the number and 

 length of the dorsal protruding sette on the three distal 

 joints and as to the depth of the tarsus so much with those in 

 S. neotropica, that a reference to the figure and to the 

 description of the species named is suflEicient ; only the claws 

 (fig. 3 c) differ i-ather considerably : they are proportionately 

 slender, the posterior strongly curved and slightly shorter 

 than the other, and the front seta is rather short. The first 

 pair (fig. 3 d) are small oblong knobs, with some hairs and 

 two seta), one of which is long. 



Cerci (fig. 3e). — They are somewhat shorter than the last 

 pair of legs, slightly more than four times longer than deep, 

 and scarcely broader than deep. They are set with a 

 moderate number of setos, of which eight to ten on the whole 

 outer surface arc longish or long, one on the upper side 

 nearly as long even as the depth of the cercus, and strongly 

 protruding downwards, outwards, or upwards; the other setae 

 are moderately short nnd depressed. 'JMie torminnl area at 

 least two thirds as long as the depth of the cerci ; the surface
