26. Sph^erotherium stigmaticum, n. sp. (Plate XIX. fig. 3.) 



Dull testaceous ; eyes, antennae, and legs greenish olivaceous. 

 Head smooth, shining in front and coarsely punctured, deeply 

 sinuated behind ; nuchal plate smooth, with central area slightly 

 projecting and forming a double oval ; dorsal segments depressed, 

 smooth, scarcely perceptibly punctured behind, their lateral wings 

 finely but densely punctured ; last segment finely rugose, shining 

 behind, somewhat compressed at the sides ; its posterior margin 

 somewhat projecting, and just above it a well-marked subtriangular 

 raised spot. 



Length 1 inch 4 lines, width 9 lines. 



Madagascar. Two examples. Coll. Saunders. 



Evidently allied to S. titanus, but having the dull aspect of 

 Zephronia innominata. 



The following species are of doubtful location : — 



27. Sph^erotherium ovale. 



Julus ovalis, Linnaeus, Amcen. Acad. iv. p. 253. n. 36, pi. 3. f. 4 

 (1788). 



Julus ovatus, Fabricius, Sp. Ins. i. p. 528. n. 1. 



China. 



This species, unless the type turns up, will never be identified 

 with certainty. It appears to be a narrow species, probably not 

 unlike Zephronia innominata in form. 



28. Sph^erotherium gronovii. 



Sphcerotherium gronovii, Brandt, Rec. Mem. Myriap. p. 180. 



Oniscus cauda subrotundata, $c, Gronov. Zooph. p. 233. n. 995, 

 pi. 17. f. 4, 5 (1764).

 pi. 59. f. 5, 6. 



" Seas of Norway and England " {Gronov). 



But for the antennae, which are those of a Sphcerotherium, this 

 might have been identified with Zephronia chitonoides. It is pro- 

 bably allied to £. neptunus.
