gular areas by lines formed of green or blue-green scales ; but here 

 the number and disposition of these areas are different, there being 

 three central or sutural areas, whilst in P. quadrulifer there are but 

 two : the total number of areas is eleven ; in P. quadrulifer there are 

 fourteen. Between the eyes is a longitudinal groove, and imme- 

 diately in front of them is a transverse furrow, through which the 

 longitudinal groove is continued, and terminates about the middle of 

 the rostrum. The thorax is margined with green in front and at the 

 sides, besides which there are two longitudinal green lines, one on 

 each of the disc. The space between the two last-mentioned lines 

 presents a few scattered small punctures, but towards and at the 

 sides the thorax is smooth ; the length and width of the thorax are 

 very nearly equal ; in front and behind it is truncated, and in the 

 middle it is slightly swollen. The elytra are rather less than twice 

 as broad as the thorax, convex, ovate, attenuated behind ; they are 

 punctured, and the punctures are small, rather scattered, and have a 

 tendency to arrange themselves into striae. 



Apocyrtus metallicus. 



Ap. aeneus, nitidus, thorace maculis duabus superne, duabus antice et utrin- 

 que una ; elytris distincte punctato-striatis maculis sexdecim ; his maculis 

 e squamis viridi-aureis. Long. corp. 4| lin. ; lat. If Hn. 



The Ap. metallicus and Ap. lavicollis are the only two species of 

 the present genus I am acquainted with in which the ground-colour 

 *of the body and legs is metalHc : the colour is the same in both spe- 

 cies, being sometimes of a bronze hue, and sometimes having a slight 

 copper-like tint. Ap. metallicus is readily distinguished from Ap. Irs- 

 vicollis by the elytra being adorned with smallish round spots, which 

 are of a golden or golden green colour, the last-named species ha- 

 ving narrow bands instead of spots. The rostrum is rather finely 

 punctured in front, has a longitudinal groove, and is separated from 

 the head (which is almost destitute of punctures) by a very deep 

 transverse channel. The thorax is small compared with many of the 

 genus, subglobose, truncated before and behind, glossy, and very di- 

 stinctly punctured ; on the anterior margin is a small spot on each 

 side immediately behind the eye ; on the lateral margin is another 

 and larger spot, and there are two small spots on the upper surface 

 about midway between the anterior and posterior margins, and rather 

 widely separated from each other. The elytra are of an ovate form, 

 and distinctly punctato-striated : on each elytron are eight round or 

 nearly round spots, viz. two at the base, two in a transverse line in 

 the middle, three, also in a transverse line, behind the middle, and 

 one near the apex : on the abdomen beneath are four spots. All 

 these spots are formed by golden green scales. 



Apocyrtus Icevicollis. 



Ap. asneus, nitidus ; rostro punctato, sulca longitudinal!, et ad basin pvo- 

 funde transversim impresso ; thorace subgloboso, indistinctissinie punc- 

 tulato; marginibus squamis caeruleo-viridibus ornato ; elytris rotundato- 

 ovatis, punctato-striatis, fasciis duabus et versus apicem punctis duabus
