Genus Zephronia, Gray. 



Griffith's Animal Kingdom, XIV, pi. cxxxv, fig. 5 ; also XV, p. 796 



(1832). 



Zephronia tumida (Butler), pi. B., fig. 8-8 b. 

 Zephronia tumida, Butler, Ann. Nat. Hist. ( 5 ) IX, p. 196, fig. 1 

 (1882). 



Colour. — Head and nuchal-plate black ; anterior half of tergites 

 testaceous ; posterior half black ; striped very much as in Z. tigrina. 



Tergites. — Anterior half, except of first, thickly granular ; posterior 

 half thickly and finely punctured. 



Head thickly punctured below, less thickly above. 

 Nuchal-plate sparsely punctured above, thickly below, where it is 

 marked by a nearly straight fine ridge. 



2nd tergite with anterior border vertical ; lamina scarcely developed, 

 represented almost wholly by the slightly thickened edge of the 

 tergite. 



Anal tergite {$) very slightly hollowed towards its free margin, 

 without marginal notch, and with inner ridge represented merely by two 

 black tubercles. AntenncR with apical segment considerably dilated. 

 Legs as in Z. nigrinota. Forceps almost exactly like those of Z, 

 nigrlnota ; in the first pair the immovable dactylus is more cur\-ed and 

 bears a tooth at the base, and the distal segment of the movable 

 dactylus is much smaller; in the second pair the distal segment of the 

 movable dactylus is slightly dentate at the apex. 

 Length 42 mm. 



A single male specimen from Coremia, North Assam (E, W. P. Cam- 

 bridge). In sculpturing this species resembles those allied to Z. oralis 

 (Gray), but the form of the forceps seems to indicate greater affinity 

 with Z. nigrlnota.
