and Species of Eumolpida. 886 



three joints of the antennae testaceous, the rest fuscous. Thorax 

 faintly emarginate at the sides, without denticulation : disk 

 smooth, shining, with irregular punctures, much larger than 

 those of the head ; in the middle an impunctate space. Scu- 

 tellum shining, impunctate. Each elytron with eight smooth 

 costse (exclusive of the sutural and lateral margins) ; the first, 

 next the suture, continued to the apex ; the second and eighth 

 branching from a common stem near the apex, and including 

 within their fork the third to the seventh. The fourth and sixth 

 likewise originate from a common stem, which unites with the 

 second near the apex. The interstices punctate- striate, the 

 punctures geminated. Each elytron with a large, oblong cya- 

 neous blotch extending four-fifths of its length, bordered all 

 round with testaceous, and emarginate in the middle of its in- 

 terior edge. Extreme tips of the tibiae and the whole tarsi red- 

 dish brown ; the rest entirely bright testaceous, deeper on the 

 head and thorax.

Metaxyonycha crucifera, sp. ined. 



M. testacea, antennarum artieulis 4-12 nigris ; thorace elytris multo 

 angustiore, lateribus medio indistincte subbidentatis ; elytris baud 

 costatis, fortiter confertim subseriatim puuctatis, singulis plagis 

 duabus magnis cyaneis.

Very similar to M. connexa, but distinguished by having the 

 thorax much narrower in proportion, and very obsoletely biden- 

 ticulate at the middle on each side. Elytra punctate-striate, the 

 strise indistinctly geminated; the interstices between each pair 

 smooth, slightly raised, but not costate as in M. connexa. Each 

 elytron with a large cyaneous blotch, bisected at right angles 

 by a narrow testaceous stripe, forming four cyaneous spots upon 

 the back; the two anterior spots quadrangular, rounded in 

 front; the two posterior triangular, nearly reaching the apex. 

 The testaceous suture and the transverse stripe form together 

 a Roman cross, from which the species is named. In other 

 respects similar to M. connexa.

Metaxyonycha chlorospilota, sp. ined. 



M. testacea, subnitida, antennarum artieulis 6-1 2 nigris; thorace 

 parce punctulato, lateribus medio edentatis : elytris subcostatis, 

 punctato-striatis, punctis inter strias geraellatis ; singulis maculis 

 duabus cyaneis, altera humerali, altera pone medium laterali.

Similar to the two preceding, but subnitidous and more
