smooth line in the middle; at the base there is on each side a small smooth spot. 

 Besides the deep impression at the base of the elytra, there is a much less marked one 

 on the humeral callus ; near the suture there is a fine costa, but it does not extend to 

 the base, and diverges slightly from the suture near the apex, and then at the apex 

 turns sharply towards the sutural angle ; there are two indistinct longitudinal smooth 

 lines between the discoidal impressions, and the subapical impression has two short 

 lines emitted from its posterior margin. The apical segment of the abdomen is biden- 

 tate, coarsely punctured, with a smooth median line (Tab. III. fig. 16 a).

The type of this species is now in the British Museum, and is unfortunately still 

 unique. The following and other species have been confounded together and mistaken 

 for it. The species referred to under this name by Dr. Horn (I. c.) must, I think, be the 

 one described below as C. costifrons.

This species is very near C. wrea, but has the thorax and elytra shorter, the latter 

 less gradually narrowed towards the apex, and widest rather behind the middle. The 

 fovea at the base of the elytra is smaller and more punctiform, and not extended on to 

 the humeral callus, although there is a very slight impression on the callus; the 

 impression on the disc is much smaller, not more than one third the width of the 

 elytron, coppery on the sutural end, shallow on the outer side ; the posterior impression 

 is large ; the sutural costa is well marked, but does not extend to the base ; two other 

 costas may be traced behind the posterior impression. The apical segment of the 

 abdomen is not tridentate as in C. wrea, but emarginate in the male (Tab. III. fig. 17 a), 

 and notched in the female (fig. 11 b). 



29. Chrysobothris stellifera. (Tab. III. fig. 18.) 



Elongata, elliptica, parum convexa, crebre rugulosa et punctata ; capite vertice linea elevata lasvi : thorace 

 transverso (lateribus medio fere parallelis), antice posticeque paullo angustato, disco subtiliter punctato, 

 punctis nonnullis majoribus intersparsis, lateribus rugosis ; elytris postice gradatim angustatis, ad apicem 

 paullo serratis, singulo basi puncto aurato bene impressa, ante medium fovea rotuDdata aurata, post
