 Sikkim. By Arthue Gardinee Butler, F.L.S., F.Z.S.,

[Plate XVI.] 



The collection of the British Museum has lately been enriched 

 by the addition of the following interesting new species of 

 Zephronia and Sphmr other iura. 



Zephronia Icevissima, n. sp. Plate XVI. figs. 4, 4 a, 4 b. 



Blackish pitchy, clouded with dark castaneous ; head pitchy ; 

 antennae castaneous ; nuchal plate black. 



Head somewhat coarsely punctured all over, more densely 

 in front, its anterior area clothed with short bristles ; antenna? 

 clothed with bristles ; nuchal plate with a slight anterior ridge, 

 a few scarcely perceptible punctures along its front margin : 

 dorsal segments highly polished, finely granulated in front'; 

 lateral segmental wings rather wide; first dorsal segment with 

 anarrow sloping lamina, having a narrow lateral marginal ridge ; 

 last dorsal segment unusually perpendicular, its external edge 

 arched, with a narrow marginal ridge. 



Length about 1 inch 4 lines ; depth of head 2 lines, width 

 of head (including the eyes) 5 lines. 



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



I find that a second example, apparently, of this species, 

 destitute of head and nuchal plate, was referred by me to my 

 Z. nigrinota. It differs from the latter species in its more 

 finely and sharply punctured head, much more highly polished 

 dorsal segments, less pronounced lateral marginal ridge to 

 lamina of first segment, more perpendicular last segment with 

 more arched external edge, and deeper coloration. 



Zephronia excavata, n. sp. Plate XVI. figs. 1,1a. 



Testaceous, transversely clouded with olivaceous ; the poste- 

 rior margin of each segment reddish, the external edge being 

 pitchy ; occasionally a few rounded testaceous spots and a 

 number of blackish dots scattered here and there over the 

 segments. 



Head somewhat coarsely but not densely punctured, slightly 

 hairy ; antennae hairy : dorsal segments perfectly smooth ; 

 first dorsal segment with a narrow sloping lamina, having a 

 narrow lateral marginal ridge ; last dorsal segment oblique, 

 compressed, arched and distinctly excavated from the centre 

 to near the outer edge.
