WITH DESCRIPTIONS OF NEW SPECIES 29 



the longest seta in front of this angle being shorter than the 

 breadth of the basal antennal joint. The posterior angles 

 are broadly rounded and closely set with numerous short, 

 blunt, fusiform setae up to the angle at anterior third ; other 

 setae moderately long, slender, and acuminate. 



Antenna long and slender, measuring one-half the length of 

 the body, and composed of thirty-eight joints. The setae on 

 the inner side of the antennae are not longer than those on the 

 outer side. The secondary whorl does not appear to com- 

 mence until about the tenth joint, and is well-developed from 

 the 19th joint to apex. 



Scuta. —With the exception of a single pair of rather long 

 and pointed anterolateral setae on the first scutum, all the 

 setae on the scuta are of a peculiar and distinctive type. 

 They are moderately closely set, short, blunt at tip, and 

 broadest about the middle, or in other words, more or less 

 roughly fusiform ; none are exceptionally long, a pair at the 

 posterior angles of at least the second and third scuta being 

 about one-half as long again as the others. The second 

 scutum is widest posteriorly with the hind angles broadly 

 rounded ; the posterior margin is almost straight. The pen- 

 ultimate scutum is somewhat similar in shape, but is less 

 strongly narrowed anteriorly, and has the hind angles less 

 broadly rounded. 



Legs. — The legs of the last pair are similar to those in 

 S. caldaria, the setae on the outside margin of the tibia and 

 some of those on the meta-tarsus are short and rather blunt, 

 somewhat similar to those on the scuta, whilst there are at 

 least ten spines in the outer dorsal row of the tarsus and 

 about as many in the same row on the meta-tarsus. The 

 tarsus is slightly longer compared to its depth than in 

 caldaria. 



Cerci. — At least four or four and one-half times as long as 

 broad ; clothed with a moderate number of long stiff setae, 

 most of which are at least half as long as the depth of the 

 cercus. The terminal setae are broken off in our single
