A PONOGRAPH OF THE PILL-MILLIPEDES. 471 



Zeplironla comotti^ (Vooook). 

 Ann. Mus. Genova (2), X, p. 391, fig. 5 (1890). 

 This species is smaller than gestri^ which it much resembles iu colour 

 and sculpture. The laminate portion of the 2n(l tergite is however 

 considerably larger, and the copulatory forceps are differently shaped. 

 Length about one-third of an inch. 

 Locality. — Minhla, in Burma {G. B. Comotto), 

 Zephronia ere pilaris (Pocock). 

 Ann. Mus. Genova (2) X, p. 392, fig. 6 (1890). 

 In size, colour, and ornamentation the species very' closely approaches 

 Z. comotti and Z. gestri, of which only the males are at present known. It 

 may however be at once recognized from these two by the fact that the 

 anal legs of the male are very long with strongly curved femur ; and the 

 second pair of forceps of the copukitory apparatus are peculiarly 

 modified, having short stout digits, with a stridulating plate attached to 

 the basal segment of the movable. 

 Length half an inch. 

 Locality. — Rangoon (E. W. Gates).
