male o{ F. plebeia, and writes regarding them as follows :— " I re- 

 gard these two specimens as belonging to quite distinct species. The 

 male genital somites and appendages differ very considerably in 

 detail, though identical in plan ; in the Sikkim species the terminal 

 dorsal segment is furnished with a pair of conspicuous conical 

 spines wliich curve upw^ards, forwards, and backwards from the 

 disk, and is shorter, and the upper lobe of the claspers is smaller 

 and is embraced at its lower border by the commensurately deve- 

 loped spine of the lower lobe ; while in the Ceylon species the 

 terminal dorsal segment is furnished with shorter spines, from the 

 base of each of which a small cusp is given off backwards, and the 

 sclerite is of greater antero-posterior extent; and the upper, lobe of 

 the claspers is more curved and longer, extending much beyond the 

 spine of the lower lobe ; and the intermittent organ ends in a bilobed 

 spiny brush in the one, and is apparently simple in the other." 

 P. pleheia is also near the P. seriata, Moore ' ; the latter, however, 

 is known to me only by the description and figures. 



P. pleheia is a common species in Sikkim at low elevations.
