part ; suture with a basal greyish white band reaching from the 

 base to one-third of the length, and on each side, two coalescing white 

 spots at the apex of the sixth costa, the outer sides are also sparsely- 

 pubescent ; the greyish pubescence is thicker and denser on the 

 posterior margin ; that pubescence is also discernible, although faint, 

 on the intermediate costse, and is most noticeable at the apex of the 

 first, third, and fifth, where it looks like an ill-defined transverse 

 band. Length 22-26 mm. ; width 7-8 mm. 



Very closely allied to P. leucospilota ; the prothorax is more 

 ampliated near the apex, not so long ; the elytra are a little less 

 attenuated in front, and less convex ; the costse are shorter, and so 

 is the sutural band ; the foveas are not so deep, and there is no trace 

 whatever in my examples of leucosjjilota of a transverse discoidal 

 pubescent patch.

POLYHIRMA MaEQUEZA. 



Head with a greyish tomentum ; prothorax elongato-cordate, but 

 broader in the anterior part than the two preceding species ; faintly 

 pubescent on the outer margins, broadly grooved in the centre, with 

 the groove filled with a yellowish white pubescence ; elytra elongate, 

 very depressed, each one with three costae reaching from the base to 

 half the length ; each interval with a double series of round punctures 

 divided by a slightly raised line, posterior half part faintly striated 

 without any punctures in the intervals ; a sutural yellowish white 

 band reaching from the base to the apex, but broader and better 

 defined from the base to a little short of the middle ; a subdiagonal 

 patch, moderately broad, extending from the first to the fourth 

 interval, and a small rounded white dot in the posterior part of the 

 sixth interval ; posterior half of the elytra, and outer margin briefly 

 pubescent. Length 29-31 mm. ; width 8-10 mm.

POLYHIRMA PEESPICILLAEIS, Chaud., 



Rev. ZooL, 1878, p. 187. 



Head with a greyish tomentum ; prothorax elongato-cordate, nearly 

 as broad as long, closely punctured, broadly grooved in the centre, 

 the groove filled with a greyish white pubescence ; elytra elongate, 

 depressed with the posterior part more plane than the anterior, each 

 one with three costae reaching from the base to two-thirds of the 

 length ; each interval with two series of alveolae, divided by a raised 

 wavy line, posterior part faintly striate, with evanescent punctures in 

 the intervals, a sutural whitish band reaching from the base to one- 

 third of the length, and two small coalescing white patches of the
