230 Mr. J. S. Baly on some 



obtuse ; surface finely punctured, impressed on either side at 

 the base with an indistinct perpendicular groove j placed trans- 

 versely between these grooves are several faint ill-defined 

 foveae. Elytra rather broader than the thorax ; sides parallel ; 

 disk moderately convex, more strongly and closely punctured 

 than the thorax, the punctures closely arranged in longitudinal 

 strige ; each elytron with a narrow sutural line, abbreviated 

 below the middle, and three large spots on the disk, piceous: 

 of these spots one, oblong, is placed on the humeral callus, the 

 second, trigonate^ has its base on the junction of the outer 

 margin with the disk, its apex extending nearly to the suture, 

 and the third, subrotmidate and subapical, is larger and better- 

 defined than the two others ; on the outer edge of the disk, 

 connecting the two anterior spots, is a nearly obsolete longitu- 

 dinal piceous line. 



The above description is drawn up from a single specimen, 

 kindly sent me by M. Oberthur ; but it is more than probable 

 that the piceous markings on the elytra vary in extent, and that 

 some individuals may be found in which the elytra are piceous, 

 with the outer limb and three spots on each elytron pale green. 



Pi'asonia Haroldi. 



P. elongata, modice convexa, subtus cum seutello picea, prothorace 

 prasino, capite sordide fulvo, viridi tincto, antennis extrorsum 

 piceis ; thorace leviter ruguloso, distincte punctate, ante basin 

 leviter transversim sulcato, prasino, basi et apice flavo marginato ; 

 elytris thorace vix latioribus, ad apicem paullo atteuuatis, sat 

 crebre piinctatis, viridi-flavis, utrinque disco prasino suffuso, liuea 

 suturali alteraque marginali, ante apicem abbreviatis, piceis. 



Long. Sg lin. 



Hah, Paraguay. 



Head exserted ; vertex finely punctured ; face swollen be- 

 tween the eyes ; encarpai pyriform, contiguous ; labrum 

 shining black, narrowly edged with flavous ; antennse about 

 three fourths the length of the body, moderately robust, scarcely 

 attenuated towards the apex. Thorax nearly twice as broad 

 as long ; sides rather broadly margined, straight and slightly 

 diverging from the base to beyond the middle, thence rounded 

 and converging to the apex, the hinder angles distinct, the 

 anterior ones slightly produced, obtuse ; upper surface mode- 

 rately convex, impressed in front of the base with a transverse 

 groove ; surface finely rugulose, rather coarsely punctured ; 

 the colour is pale green, obsoletely bordered at base and apex 

 with greenish yellow. Scutellum transverse, its apex broadly 

 rounded. Elytra scarcely broader than the thorax, slightly 

 attenuated towards the apex, convex, not depressed trans-
