A MONOGRAPH OF THE PILL-MILLIPEDES. 4G9 



This species is related to Z. e.vcavata, but diHTers in the particulars 

 pointed out imder that species. 



The type of Z. Icevissima does not apparently differ in any specific 

 character from the type of Z. nlgrinota. The type of Sphcerotheriwn 

 politum, although referred to as another genus by Mr. Butler, is merely 

 a female specimen of ntgrinota. 



Zephronia dor ice (Pocock). 



Ann. Mus. Geneva (2), IX, p. 79, fig. 1(1890) ; also op. cit. (2), X, 

 p. 394 (1890). 



In this species the colour of the segments is chestnut-brown, with 

 the posterior border black, but the black stripe is not sharply defined 

 in front. 



In front the segments are thickly granular, and behind the granular 

 area are a small number of scattered punctures. Head, nuchal-plate, 

 and 2nd tergite distinctly punctured ; anal tergite much more closely 

 punctured throughout, without marginal groove, but longish undivided 

 inner crest. 



Length 37 nun. (nearly 1 ^ inch). 



Locality. — Kachin Hills, east of Bhamo, Upper Burma (L. Fea). 



Zephronia fece (Pocock). 



Ann. Mus. Geneva (2), IX, p. 80, fig. 2 (1890) \ also op. cit. (2), 

 X, p. 394 (1890). 



This species is easily recognisable from Z, dorice by being of a dark 

 yellow or rather green colour, indistinctly clouded with paler yellow, 

 and by having all the segments densely and closely punctured through- 

 out above. It is also of much smaller size, measuring a little less than 

 one inch in length. 



Locality. — Teinzo on the Moolay River, north-east of Bhamo, and 

 Kachin Cauri to the east of Bhamo, Upper Burma (L. Fea). 



Zejjhronia clivicola (Pocock), 



Ann. Mus. Genova (2), X, p. 386, fig. 1 (1890). 



This species is very closely related to Z. fea in colour and in the 

 majority of its structural character. The first pair of forceps of the 

 Gopulatory organ however are rather differently formed, and the colouring 

 is less mottled, the anal tergite being a uniform yellowish brown. It is 

 also- a little larger, measuring about 1^ inch in length.
