new species of Sphoirotherhim. and Zeplironia. 301 



its redder colour, much more brilliantly-polislied surface, 

 shorter nuchal plate, and the much more oblique anterior 

 edges of the lateral wings of the dorsal segments. 



SphcEr other lum reticulatum, n. sp. 



Piceous ; the borders of the segments reddish casta- 

 neous; head, nuchal plate, and anterior ridge of the first 

 dorsal segment spotted with black ; under surface, legs 

 and antenna testaceous; eyes green. 



Head smooth, shining; coarsely punctured, densely in 

 front and sparsely towards the back; deeply sinuated 

 behind as in the preceding species ; dorsal segments 

 covered ivith impressed reticulations ; first dorsal segment 

 with gradually-formed lateral laminre and strongly-defined 

 marginal ridge, thicker towards the firont; dorsal segments 

 gradually increasing in length from, the second to the 

 ninth and then gradually decreasing, so that the inferior 

 margin of the Myriopod, when viewed in pi'ofile, is dis- 

 tinctly convex; anterior margins of the lateral wings very 

 oblique, with linear marginal rim. 



Length 8^ lines ; width 4^ lines. 



Madagascar. (Two examples.) 



Zephronia larvalis, n. sp. 



Pale olive green, clouded (near the back of the dorsal 

 segments, on the head and along the front of the nuchal 

 plate) with dark green ; posterior borders of the segments 

 reddish, traversed by submarginal yellow lines ; front of 

 head lilacine-reddish, niichal plate also reddish, with 

 yellowish margins ; under surface, legs, antennse and eyes 

 pale green ; last dorsal segment with an irregular blackish 

 central spot.* . 



Head smooth, sparsely but very coarsely punctured, 

 deeply sinuated behind, and with a distinct protuberance 

 in front of the sinus ; nuchal plate rather short, tvith a 

 strongly-defined anterior ridge, the impression behind 

 which is coarsely punctured ; posterior portion of the 

 nuchal plate with rather abruptly convex outline and xoith 

 two well-marked central tubercles divided by an abbre- 

 viated impressed longitudinal line; first dorsal segment 

 with a well-defined, thickened marginal ridge, behind 

 Avhich runs an oblique and flat surface, continuous with 



* Perhaps an individual peculiarity.
