just above tlie line of the insertion of tlio antennjie ; in this in- 

 dentation are some metallic scales : the rostrum moreover is very 

 indistinctly punctured. 



Sp. 16. Pachyrhynchus dectissatiis, Waterh. 



Ater, lined transversa apud thoracis medium et pone banc 

 lineis tribus longitudinalibus, nee non margine externo aureo- 

 viridibus ; elytris, linea central! transversa, lineis qnatuor ad 

 basin longitudinalibus, et pone transversam lineis duabus 

 longitudinalibus, his lineam parvulam incurvam lateralem 

 emittentibus ; lineis omnibus sic et marginibus elytrorum 

 splendide aureo-viridibus.

This species approaches most nearly to P. phaleratus and 

 P. chlorolincatus : it is, however, at once distinguished from the 

 first of these species, by there being no metallic line on the suture 

 of the hinder half of the elytra, and by there being two lines in 

 a longitudinal direction on the basal half of each elytron ; the last 

 mentioned character also serves to distinguish it from P. cliloro- 

 Ihieatits ; as well as there being a small curved line branching 

 out of each of the longitudinal lines on the hinder half of the 

 elytra, (which are, as it were, a continuation of the innermost 

 longitudinal line on the base of the elytra,) and three longitudinal 

 lines instead of one on the hinder half of the thorax. On the 

 head is a central longitudinal line of metallic scales situated in a 

 broad groove between the eyes, and a transverse metallic line 

 situated in a deep irregular groove between the antenna^ ; there 

 is moreover an oblong spot under each eye, and a patch of metallic 

 scales on each side of the rostrum, which is rather distinctly 

 though minutely punctured. The thorax has a transverse line 

 near the middle, which does not extend to the outer margin ; a 

 line encircles the thorax in front, but is interrupted in the middle 

 above, and joining this line is a curved longitudinal band on each 

 side of the thorax, and a central mark beneath : on the hinder 

 half of the upper siul'ace of the thorax are three longitudinal 

 lines ; all these lines, as well as some spots and markings on the 

 under side of the body, and the lines on the elytra, are formed of 

 brilliant golden scales, having a slight greenish hue. Besides the 

 lines on the elytra before noticed are two small spots, one on each 

 side near the apex. The elytra are very obscurely punctate- 

 striated.
