\_Fontaria variaia, sp. n. (PI. XI. figs. 15, 15 a.) 



(^. — Colour. Upper surface rather thickly clouded witii 

 fuscous, with a clearer spot on each side above the keels ; 

 the keels and the posterior border of the tergites, the legs, 

 antenna, and lower surface flavous ; a fuscous patch on the 

 face. 



Allied to the two preceding species, but with the keels a 

 little larger and rather more produced posteriorly. 



Copuiatory feet terminating in two nearly contiguous, un- 

 divided, pointed, strongly curved processes. 



Length 29 millim. ; width across keels 6, across cylindrical 

 part of segment 4. 



Loc. Great Loo-Choo (Hoist Coll.). A single specimen. 



Differs from the two preceding in colouring, size, shape of 

 keels, and structure of copuiatory feet.] 



\_Fontaria coarctata, sp. n. (PI. XI. fig. 11.) 



Colour (dry example) almost entirely pale testaceous, the 

 segments at the hinder end of the body tinted with yellowish 

 red. 



The segments of the body not pressed together with con- 

 tiguous keels ; the keels above the middle of the sides 

 moderately large, with the anterior and most of the posterior 

 angles rounded ; the posterior angles nowhere acute and only 

 projecting backwards beyond the border of the tergite in 

 about the seven posterior keel-bearing segments ; the keel- 

 bearing area lightly impressed transversely on its upper 

 surface; the caudal process not laterally spiniform, but 

 apically distinctly bifid ; the a7ial sternite posteinorly spini- 

 form, as in F. lacustris. 



Legs with long spines ; the distance between the posterior 

 coxa? greater than the length of one of them. 



The copula tori/ foot enormously long and slender, completely 

 curled backwards upon itself, with a distinct spine on its inner 

 surface just before the bend ; on its outer side near the end it 

 bears an elongate inwardly directed lamina, which ends 

 distally in three processes, two short and contiguous and one 

 longer and curved ; the end of the organ is divided into 

 three processes, the internal being styliform, the median 

 stout, more or less spatulate and bifid, and the external thin, 

 compressed, pointed at the apex, and furnished with an acute 

 process in front of the apex. 



Length about 40 millim. ; width across keels 6, width 

 between keels 4. 



Loc. Japan (/. R. Leech). A single male example.
