XXIV. — Dp.scriiHions of new Species of Myriopoda of the 

 Genus Zeplironia from India and Sumatra. By ARTHUR 

 G. Butler, F.L.S., r.Z.S.,&c. 



The following species have been received during the last two 

 or three years, and are all perfectly distinct from any species 

 hitherto named. 



1. Zephronia tumida.^ sp. n. (Fig. 1.) 



Head and nuchal plate blackisli ; first dorsal segment dull 

 castancoua, clouded on the borders with blackish ; second to 

 eleventh dorsal segments with a broad 

 ochraceous band in front (the anterior mar- 

 gins of these bands being laterally excava- 

 ted), otherwise blackish ; a faint indication 

 of a dusky dorsal line down the centre and 

 one or two blackish dots here and there upon 

 the ochrcous bands ; last dorsal segment 

 dull castaneous, with blackish posterior 

 margin ; eyes, antennae, and tarsal claws blackish, and re- 

 mainder of legs dark piceous as usual. 



Head rather narrower than usual, sparsely but deeply punc- 

 tured, more finely and densely in front, obliquely shelved in 

 front and deeply impressed with a small anchor-shaped em- 

 bossed marking just above the mouth ; the central area and 

 sides longitudinally swollen, as in no other species ; the poste- 

 rior margin rather deeply excavated ; nuchal plate a little 

 shorter and less tapering at the extremities than in the allied 

 species, with a linear anterior marginal carina, coarsely and 

 sparsely punctured excepting along the anterior border, where 

 the punctures are numerous, fine, and irregular ; dorsal seg- 

 ments finely but densely and deeply punctured, almost granu- 

 lose ; the lateral wings of the first segment narrow, granulose, 

 with very slender marginal carina ; terminal segment, viewed 

 in profile, very slightly oblique, with a slight depression at its 

 posterior third. Length 48 millim.; width 21 millim. 



N. Assam. Type, B.M. 



I have taken the above description from a single adult 

 spirit-specimen recently presented to the collection by F. O. 

 P. Cambridge, Esq. Tiie species in coloration and pattern 

 comes nearest to Z. tigrina and zehraica^ but differs from the 

 former in its more swollen head, greater width, and altogether 

 different punctuation, and from the latter in its swollen instead 

 of smooth head, densely punctured segments, and differently 

 formed terminal segment.
