186 Mr. A. G. Butler on new Species of Glomeridas. 



Length 8 lines ; depth of head 1 \ line, width of head 

 3 lines. 



Hah. Sikkim {Whitely). Four specimens. B.M. 



Differs from all the described species in the form of the 

 last dorsal segment. 



Sphcerotherium politum, n. sp. Plate XVI. figs. 2, 2 a, 2 b, 2 c. 



Blackish pitchy, a few rounded orange spots on last two 

 segments ; antennas dull castaneous. 



Head somewhat coarsely punctured all over, more densely 

 in front ; its anterior area clothed with short bristles ; antennas 

 clothed with bristles ; nuchal plate with ill-defined anterior 

 ridge : dorsal segments highly polished, scarcely perceptibly 

 granulated in front ; first dorsal segment with a narrow sloping 

 lamina, having a well-defined narrow lateral marginal ridge ; 

 last dorsal segment with a narrow marginal ridge. 



Length 1 inch 5 lines ; depth of head 2 3 lines, width of 

 head 5| lines. 



Hob. Sikkim {Whitely). One specimen. B.M. 



Allied to Zephronia javanica ; but larger, wider, the head 

 less densely punctured, and the colouring entirely different. 



Sp7icerotherium maculatum, n. sp. Plate XVI. figs. 3, 3 a, 3b. 



Olivaceous, spotted with ochraceous, the hind margins of 

 the segments castaneous ; head, nuchal plate, and first segment 

 in young specimens castaneous, spotted with olivaceous ; in an 

 old specimen (which is altogether redder in tint) the head, 

 nuchal plate, and front of first segment are pitchy ; eyes 

 greenish. 



Head coarsely but sparsely punctured, more densely round 

 the mouth, clothed with short, almost imperceptible bristles ; 

 antennas clothed with short bristles ; nuchal plate with ill- 

 defined anterior ridge, two or three punctures in front, and a 

 bisinuate depression on its posterior area : dorsal segments 

 smooth ; first dorsal segment with a narrow sloping lamina, 

 having a narrow lateral marginal ridge ; last dorsal segment 

 oblique, slightly compressed. 



Length about 9 lines to 1 inch 2 lines. 



Hah. Sikkim (Hooker & Whitely) . Three specimens. B.M. 



Our larger example of this species having come in the same 

 collection with an example of Zephronia nigrinota, and being in 

 general appearance very like it, I find that I overlooked its 

 structural distinction from that species. The two young ex- 

 amples recently received are altogether more lively in appear-
