Synojms of Species. 



I. 



Prothorax cordiform, with the broadest part gradually 

 rounded, a deep transverse impression in the anterior part ; 

 elytra plane, parallel. 



Type A, hicjuttata. 



Elytra with four much-raised costse, intervals subcostate, filled 

 with a fulvous pubescence, with an elongated subhumeral white 

 patch on each side, divided by the fourth costa, an elongated 

 band at the apex of the fourth interval, a narrower marginal one, 

 and an apical, juxta-sutural round spot of the same colour . . bigtittata. 



Elytra with one elongated spot on the third interval ; postical 

 band and spot very narrow and small sexcostata. 



The three alternate costse very raised, no alternate ones visible, 

 an ovate patch on the third interval ; posterior band and spot 

 well defined namaqua. 



The alternate costse very slightly higher than the intervening 

 ones, markings of hicjuttata, but intervals hairless costata. 



All the costse of the same height, no pubescence, a white 

 ovate patch on the sixth and seventh costse on each side ; 

 posterior band and spot well defined . . . . propinqua. 



All the costse of the same height, two short white bands on 

 the fifth and sixth intervals, a posterior supra-marginal one 

 reaching from the apex to one-fourth of the length, no apical 

 spot mima. 



Elytra more or less deeply striate and having on each side a 

 supra-marginal white band, reaching from below the shoulder 

 to the apex, and a sub-basal short band on each of the two 

 intervals adjoining the supra-marginal band limbata. 



Elytra more or less deeply striate, having on each side a 

 supra-marginal white band and a sub-basal ovate pale fulvous 

 patch on the fifth and sixth intervals, but extending sometimes 

 from the third to the seventh cephalotes. 



Elytra costate, supra-marginal band narrow, a small white 

 dot on the sixth interval ovampoa. 



Elytra very parallel, costate, having on each side a narrow 

 supra-marginal white band, and a round patch on the fifth and 

 sixth intervals, the spot much nearer the median part of the 

 disk than in the other species cEqitilatera. 



Elytra costate, convex, with only a supra-marginal white 



band torva. 



. Elytra with only a supra-marginal white band reaching from 



the apex to one-third of the length desertoriim. 



II. 



Prothorax with the anterior part arcuated, the posterior angle 

 very acute, posterior part diagonally narrowed, posterior angles 

 subobtuse, a white spot on each side of the anterior part ; elytra 

 elongato-ovate, strongly costate. 



Type A. decemguttata. 

 Elytra with four acute costse on each side, intervals hardly 

 pubescent, five white elongated patches on each elytron . . . . decemguttata.
