248 SPOLIA ZEYLANICA. 



I have much pleasure in dedicating this species to Mr. S. W. 

 Kemp, of the Indian Museum, who kindly made the collections 

 for me at Kilakarai and Paumben, in which this species 

 occurred. 



Genus Tortanus, Giesbrecht. 



ToRTANcrs GRACILIS (Btadv). 



(PI. XXL, fig. 5.) 



Torianus gracilis, Cleve, 1901, p. 5. PI. VII., figs. 11-14. 



A. Scott, 1902, p. 423. 



Thompson & Scott, 1903, p. 254. 



Cleve, 1903, p. 3G9. 



Wolfenden, 1905, p. 1026. 



A. Scott, 1909, p. 190. 



Sewell, 1912, p. 377. 



Several examples of this species, belonging to both sexes, 

 were present in the Ceylon collections. 



Both Cleve and Wolfenden are inclined to believe that this 

 species and the following, T. forcipatus, are synonymous, but a 

 careful study of the examples in the present collection has 

 shown that this view is absolutely untenable. For the 

 purpose of comparison I give below a few details of structure 

 in this species. 



$. The first antenna consists of seventeen joints, having the 

 following relative proportions : — 



Segments : 1-7, 8. 9-10. 11. 12. 13-14. 15. 16. 17. 

 87 18 52 28 28 74 52 52 59 



Segments 1-7,9-10, and 13-14 are, apparently, respectively 

 fused together. The fifth pair of legs, as j>ointed out by Cleve 

 {f,oc. cit., 1901), are asymmetrical, but the degree of as3''mmetry 

 is very slight, and not in the least comparable to that present 

 in the corresponding appendages in T. forcipatus.
