ei«j;liteeiith segment, not beaded. The sulcus marking the 

 constrictifin not sculptured. 



Coudal process truncate, triangular, not conspicuously 

 tubercular. 



Anal stermle oval, the two tubercles not projecting beyond 

 the edge. 



The lateral surface lightly wrinkled, the inferior keel 

 distinct to the hinder end of the body, crescentic. 



The sterna^ except at the anterior end of the body, with 

 two pairs of backwardly directed blunt spines, one at the base 

 of each leg. 



Legs with distinct claws, normally hairy ; femora about as 

 long as the tarsi, twice as long as the trochanters, but not 

 twice as long as the tibia?. 



Length 35 millim. ; width across keels 3 8, width between 

 keels 3. 



Loc. A single female example from Chee Foo [Sivinhoe 

 Coll). 



Tliis species is perhaps allied to the Japanese Oxyurus 

 flavo-Umhatus of L. Koch (Verh. z.-b. Wien, xxvii. p. 795, 

 1878), but the latter seems to have better developed keels 

 and to be differently coloured ; for the keels, including those 

 of the first segment, are said to be yellow, whereas in this 

 new form the tirst tcrgite is not yellow laterally and only the 

 posterior portion of the keels of the rest of the segments is 

 this colour. 



In colouring S. Swinhoei presents a strong likeness to two 

 other sjjecies, namely S. transverse-tceniatum of L. Koch, from 

 Australia, and S. Phipsom, Pocock, from India. But in 

 neitlier of these two species are the sterna spined ; moreover, 

 in I'/iipsoni the first tergite is entirely bordered with yellow, 

 and in transverse-ticniatuin the yellow band on the tergites 

 does not extend on to the keels.] 



\^Strongylosoma Holstii, sp. n. (PI. XI. fig. 3.) 



? . — Colour. Head and antennas black, the segments with 

 yellow just above and on the keels, and a large yellow spot 

 on the middle of each ; this j^ellow spot extends on to the 

 anterior part of the segments, and tlius the series of them 

 forms a continuous median dorsal stripe ; the lateral surface 

 black above, yellow below ; legs and sterna yellow. 



AntenncB incrassate, with segments increasing in length 

 from 2 to 6, the sixth being noticeably longer than the 

 second. 



Body smooth above ; the keels small, just above the middle
