marked by the large semilunar patch on the elytra extending 

 from the shoulder to near the apex and meeting its fellow at

Ilab. Christchurch. 



This very distinct species may at once be known by its 

 short elytra. The genus Sessinia was published by me in 

 January 1863 (Journ. of Entom. ii. p. 45, note). Ananca, 

 Fairm. et Germ. (Ann. Soc. Ent. de Fr. 4« S(?r, iii. p. 267, 

 1863), must have been published some months later, as a 

 subsequent paper (p. 293) Avas read at the "stance" of the 

 10th June in the same year. Dryops lineata, Fab. (Ent. 

 JSyst. i. pt. 2, p. 76), and Dryops strigipennis^ Wh. (Ereb. 

 and Terror, p. 12), belong to Sessinia. The genus is differ- 

 entiated from Nacerdes by its two-spurred tibia?. Selenopalpus 

 chalyhmus and suhviridis are probably only varieties of S. cya- 

 neus, Fab. [Dryojis],
