Synopsis of Genera. 



Ligula tridentate, no paraglossse. 



Ligula in the shape of a trident ; lobes of mentum very sharp 

 at the tip ; second joint of labial palpi more than twice as long 

 as the third ; prothorax cordiform ; elytra elongato-ovate, trun- 

 cate behind BcEoglossa. 



Ligula spatuliform, convex, and with short basal paraglossas. 



Lobes of the mentum gradually rounded outwardly, the inner 

 ■edge ending in a sharp spine. 



Head without a neck ; prothorax very plane, with the outer 

 •sides slightly rounded in front and nearly straight from there to 

 the base ; elytra subparallel, slightly convex, costate, and trun- 

 cate behind Cycloloba. 



Head with a neck ; prothorax very cordiform ; elytra flattened, 

 costate, truncate diagonally behind Microlestia. 



Head without a neck ; prothorax cordiform, subhexagonal or 

 produced behind in two lobes, plane or convex, parallel, elongato- 

 ovate or much ampliate, the posterior part rounded ; lobes of 

 the mentum broadly scooped in the apical part Anthia. 



Head with a neck ; mentum and palpi of Anthia ; prothorax 

 elongato-cordate or cordiform ; elytra subconvex, costate, with 

 the intervals more or less broadly alveolate, and the costae seldom 

 Teaching the apex, the apical part diagonally truncate Polyliirma. 



Prothorax and elytra very convex ; the posterior margin of the 

 latter broadly scooped between the outer angle and the suture . . Eccoptoptera. 



Lobes of mentum truncate at the apex ; head very long and 

 narrow ; eyes hardly prominent ; antennae very compressed ; 

 prothorax fusiform ; elytra very convex, the suture spinose on 

 ■each side Netrodera. 



Head very long ; eyes hardly prominent ; antennae not much 

 compressed ; elytra elongato-ovate, plane, costate, truncated 

 •diagonally behind Atractonota. 



Gen. ATEACTONOTA,- Perr., 

 Ann. Soc. Linn. Lyon, 1846, p. 60. 



Mentum, ligula, and palpi of Polyliirma ; the three basal joints of 

 antennae long, slender, the others compressed, subfoliate ; head 

 very narrow, very long ; prothorax very slender, fusiform ; elytra 

 -elongato-ovate, very convex, with the posterior margin broadly 

 scooped, and the apical part of the suture spinose ; legs a little more 

 slender than in Netrodera. 



No representative of this genus has yet been found beyond the 

 South African region. 



* The original name was Atractonotus ; Lacordaire changed its desinence to 

 be in harmony with those of the genera included in the tribe.
