 punctures all well defined.

 stices between some of the rows ... Palmerstoni, Blackb.

H. diversiceps, sp. nov. Elongatus ; brunneus, obscure cupreus, 

 clypeo suturaque viridescentibus, genubus tarsisque plus 

 minusve piceo-notatis ; clypeo subtiliter punctulato ; capite 

 postice indeterminate ina3quali, rugulose punctulato ; pro- 

 thorace leviter transverso, postice sat angustato, indeter- 

 minate inaequali, sat grosse subrugulose punctulato, lateribus 

 leviter sinuatis minus arcuatis ; elytris suturam lateraque 

 versus striatis, seriatim punctulatis (serierum subsuturalium 

 puncturis quam ceterarum minoribus), interstitiis internis 

 vix (externis manifeste) elevatis. Long., 1 J 1. ; lat., 4 1. 

 On each elytron the punctures of the two rows nearest to the 

 suture are in indistinct strise, and are smaller than the punctures 

 of the other rows. The next two rows of punctures do not run 

 in striae ; but the rest of the rows are in stride. The seriate 

 punctures (except those of the subsutural series) are about the 

 same size as those of the European H. angustatus, Miill., and are 

 larger than those of //. parallelus, Macl., and smaller than those 

 of H. Adelaides, Blackb. The external interstices, beginning 

 with that between the fourth and fifth rows of punctures, are 

 somewhat elevated, especially near the apex.

H. interioris, Blackb. In re-studying this insect for the 

 purpose of tabulation, I find with regret that the type was 

 covered with some kind of exudation (probably the normal 

 condition of the insect), which I overlooked ; and the exudation 

 now having, with considerable difficulty and some damage to the 

 specimen, been removed, it appears that my description (Report 

 of the Horn Expedition, II., p. 260) erred in respect of the 

 sculpture, for the head, instead of being as I called it "sequalis," 

 is trisulcate between the eyes, and the elytra should be described 

 as " having all the alternate interstices a little more elevated than 

 the rest, especially the fifth behind and the ninth in the middle," 

 instead of (as is implied in my description) "only the fifth 

 behind and the ninth in the middle more elevated than the rest."
