ATESTA. 



This species differs from Atesta in the spine of the third joint 

 of the antenna being almost obsolete, the corner of the joint 

 where the spine might be expected being merely a little pro- 

 duced in a sharp point. The three species which Mr. Pascoe 

 associated to form this genus are characterised as Phoracanthids, 

 having the characteristics of their group reduced to a minimum, 

 the antennal spines being only one or two, and the apical spines 

 of the elytra nearly or quite obsolete. This species reaches the 

 lowest point in these respects of any yet described, the spines of 

 the elytral apex being quite, 



and those of the antenna; all but,

The yellow marks on each elytron are two spots a little behind 



the base (placed transversely and probably in some examples 



confluent), a large irregularly-shaped spot about the middle, not 



quite reaching either the suture or the lateral margin, and a spot 



occupying the apex. The head and prothorax are somewhat 



finely and closely, but not very distinctly, punctured, the latter 



bearing a median lanciform nitid space with about six ill-defined 



more or less nitid tubercles on each side, some of them more or 



less run together (probably variously in different examples) so 



that they are difficult to count. The length of the prothorax is 



about equal to its width. On each side one of the tubercles 



being placed on the lateral declivity makes the segment appear 



protuberant in the middle when looked at from above. All the
