border being slightly produced backwards in tbe anterior balf of 

 tbe body and more so in the posterior half, but the keels never 

 extend beyond the level of the posterior border of the tergites, the 

 antero-lateral border -convex; border of the keels thickened and 

 elevated, those of the poriferous segments much thicker than the 

 others ; keels of the 1 9th somite not produced, tuberculif orm ; the 

 pores completely lateral and situated in the posterior half of the 

 lateral surface; 5th to the 18th furnished with a weak median 

 transverse sulcus. Lateral portion of the somites beneath the keel 

 sub-granular, the upper surface being smooth or at most slightly 

 reticulated; the 2nd to about the 18th somites furnished with a 

 conspicuous ridge aboYe the tracheal apertures. 



Sternal surface of the 5th furnished in its anteriof half with a low, 

 wide, posteriori}'- slightly elevated prominence ; sternite of the 20th 

 obtusely triangular, its posterior angle rounded, bearing a tubercle 

 on each side in front of the margin. 



Legs', femur of 5th, 6th and 7th pairs {i. e., the posterior pair on 

 the 5th and the two pairs of the 6th somites) bearing an inferior 

 prominence, which is smaller on the 5th, largest on the 7th. Copula- 

 tory feet reaching to the middle of the sternum of the 6th somite (with 

 the body etxended), the 2nd segment hairy, narrowed distally, and 

 bearing internally and posteriorly a backwardly-directed projection, 

 the 3rd segment externally convex, terminated by four processes, 

 which considered from behind forwards may be described as 

 follows — the first is slender, short, and nearly at right angles to the 

 axis of the foot, the second belonging to the same piece as the first, is 

 directed forwards, thin, blade-Kke, and pointed, the other two are 

 slender, curved and closely in contact, almost equal in length, the 

 external embracing the internal. 



Length 36 mm. 



Several specimens, all males, from Tanjore. 



This species at least differs from L. luctiiosus^ (Peters), from Ceylon, 

 in colouring ; for luctuosus is said to ha ve the posterior border 

 of the somites pale coloured. It cannot, moreover, be confounded 

 with any of the species recorded by Humbert from the same 

 island.
