pointed at base; margins wide, edges recurved; anterior angles 

 acute, produced almost to apex of head, posterior sharp and 

 strongly curved. Scutellum widely transverse. Disc of elytra 

 very much wider than that of pro thorax, bulged before middle, 

 constricted near apex, suture strongly raised, interstices irregular, 

 feebly raised; margins wide, their edges recurved. Legs moderately 

 short, claws long. Length ^ 16, 2 17, width ^ 12, 9 13| mm. 



In the male the margins are proportionately broader than in 

 the female, and they are also reflexed.

Sympetbs undulatus, n.sp. 



(J. Shining, subparallel. Reddish-brown, margins paler;

Head not projecting beyond pro thorax; clypeus wide, perfectly 

 straight in front, very feebly convex, notched at the sides; eyes

 pear-shaped, 9 th- 11th circular. Prothorax almost thrice as wide 

 as long, disc depressed on each side of middle, at sides and base; 

 margins each wider than disc, each forming the fourth segment 

 of a circle, anterior angles almost right angles, not at all produced, 

 posterior feebly curved and scarcely acute. Scutellum widely 

 transverse. Disc of elybra as long as prothcJrax is wide, ovate- 

 elliptic, suture strongly raised, each with six or seven feeble 

 irregular costae, the alternate ones stronger; mai'gins waved, in

9. Differs in being broader and more rounded; a more distinct 

 transverse impression at base of prothorax, the anterior angles 

 feebly produced; disc of elytra broadly ovate, and, except at base, 

 much wider than margins, outer edges of mai'gins below level of
