This pretty little species varies considerably in size, as will be seen 

 by the above dimensions. The rostrum is separated from the head 

 by a very deep transverse impression, and has a distinct longitudi- 

 nally impressed line ; in front it is convex, and rather thickly though 

 finely punctured. The head is very sparingly punctured ; the thorax 

 is subglobose and rather small ; its surface is glossy and is very de- 

 licately punctured ; the margins are adorned with blue-green scales. 

 The elytra are convex, of an ovate form, and nearly twice as broad 

 as the thorax, distinctly punctato-striated : at the base of each ely- 

 tron is a transverse nan-ow blue-green band, on the middle is a se- 

 cond band, and behind is a longitudinal mark running parallel with 

 and at a short distance from the suture ; joining this mark with the 

 central transverse fascia is a curved line which runs nearly parallel 

 with the outer margin of the elytron ; in the area enclosed by the 

 markings last described is a small round spot. The glossiness and 

 smoothness of the thorax will serve to distinguish the present species 

 from all others of the genus here described, excepting the Ap. metal- 

 licus, which greatly resembles the A. IcevicolHs, not only in this cha- 

 racter, but in size, form, and also in the sculpturing of the elytra : 

 this however appears to be less strongly marked in the present than 

 in the preceding species. 



Apocyrtus elegans. 



Ap. niger ; rostro supra concavo ; capite punctato, antice Hnea transversa 

 impvesso, et inter oculos stria longitudinali ; tlioi-ace subgloboso, tuberculis 

 crebris pariim elevatis obsito, supra maculis duabus, antice et ad latera, 

 squamis aureo-viridibus ornato ; elytris subseriatim punctatis, maculis or- 

 natis, his maculis, lateribusque elytrorum, aureo-viridibus. Long. corp. 

 5l lin. ; lat. 2-1 lin. 



Rather less than the Pachyrhynchus moniliferus ; the thorax smaller, 

 and the elytra proportionately more elongated. In size and disposition 

 of the markings the present species resembles the Ap. gibbirostris ; 

 but in that species the thorax and elytra are very nearly equal in 

 width, whilst in the A. elegans the thorax is considerably narrower 

 than the elytra : here the upper surface is covered with glossy tu- 

 bercles, and there is a somewhat indistinct dorsal channel ; in Ap. 

 gibbirostris the thorax is coarsely jmnctured above. 



The rostrum is concave above, rather finely punctured, and sepa- 

 rated fi'om the head by a transverse groove : the head presents largish 

 scattered punctures between the eyes, and has a longitudinally im- 

 pressed line in the same pait ; beneath the eye is a small brilliant 

 spot. The thorax is subcylindrical, but dilated in the middle ; the 

 anterior jiart is narrowly margined with brilliant scales, and there is 

 a broad patch of these scales on each side, besides two smallish round 

 spots on the upper surface : these are widely separated and situated 

 not far from the hinder margin. The elytra present a nearly ovate 

 outline, but are somewhat pointed behind ; they are distinctly punc- 

 tured, and the punctures have a tendency to form themselves into 

 lines. At the base of each elytron are two roundish spots of mode-
