thorace hand latioribus, punctis elongatis seriebus 8 alteraque brevi 

 subscutellari digestis, parum distinctis propter interstitias fortiter punc- 

 tatas ; subtus ferrugiueus confertim punctatus, breviter pubesceus, 

 propleuris dense rugosis, antennaruui articulis 8-11 sensini paulo 

 brevioribus. Long. - 4(J. 



One specimen from California, in the collection of Mr. Ulke. 

 Related to II. bachei, but the thorax is not rounded, and the 

 punctures of the interstices of the elytra are nearly as large as 

 those of the strice, so that the latter are not very distinct. The 

 under surface is also more strongly punctured, and distinctly 

 pubescent. The antenna? are somewhat shorter, more decidedly 

 thickened externally, and the joints 8-11 diminish more distinctly 

 in length. 



417. H. discretus. Apterus, aeneo-niger, capite thoraceqne con- 

 fertim aciculato-punctatis, hoc latitudine breviore, antice posticeqne 

 fere truncato, lateribus late rotundatis, angulis anticis rotundatis, pos- 

 ticus subrectis ; elytris subnitidis elongato-ovalibus, a basi paulo ampli- 

 atis et dein thorace paulo latioribus, transversim convexis, punctis 

 elongatis discretis seriebus 8 digestis, alteraque brevi subscutellari, 

 interstitiis parce subtiliter punctulatis ; subtus subtilius, propleuris 

 confluenter punctatis, ore tarsisque piceis, antennaruni articulis 8-11 

 sensini paulo brevioribus. Long. -44. 



Texas; one specimen in the collection of Mr. Ulke. Related 

 to H. cisteloides, but the punctuation of the head and thorax is 

 more dense, and distinctly aciculate, and the last joint of the 

 antennas is decidedly shorter than the preceding ; the meta- 

 sternum is less strongly, and the propleura more rugosely 

 punctured. 



IIS. H. tumescens. Apterus, robnstus, piceus, snbsenescens, capite 

 thoraceque confertim punctatis, hoc longitudine fere duplo latiore, obso- 

 lete canaliculato, lateribus postice parallelis, ante medium subangulatis, 

 apice truncato, basi late rotundata, angulis posticis obtusis ; elytris 

 ovalibus convexis, a basi ampliatis, dein thorace tertia parte latioribus, 

 striis utrinque 8, marginali alteraque brevi subscutellari impressis, 

 punctatis, interstitiis subconvexis vix conspicue punctulatis ; subtus 

 rufo-piceus sat fortiter, propleuris dense rugose punctatis, antennarum 

 articulis ultimis fere sequalibus, vix dilatatis. Long. '42. 



One specimen from California, in the collection of Mr. Ulke. 

 The antennae are nearly filiform, and the outer joints nearly three 

 times as long as their width.
