in some specimens, besides the basal spots there is an oblique black line towards the 

 margin. The 3'^ and 6^^ elytral lines alone attain the base ; at the tip they are gradu- 

 ally shorter externally, and the 4'h, 5*, and 6"» are united. Seems allied to H. frater 

 Steph. (Conf. Aube, .528). Were it not for the obsolete punctures and yellow head, it 

 would be H. lajvis, Kirby, N. Z., 68. 



*^ I must give Kirby's species as distinct, although Dr. Schaum tells me their Euro- 

 pean analogues are considered identical, lineellus being a $ variety of picipes. I have 

 both ^ $ of our species, each agreeing with its opposite sex in sculpture, and differ- 

 ing only in lustre, the $ being shining, the ? opaque. 



^8 H. tenebrosus — EUiptico-ovalis, minus convexus, niger subtiliter pubescens, mi- 

 nus dense subtiliter punctatus, capite antice posticeque obsolete ferrugineo, thorace 

 valde transverse lateribus obliquis leviter rotundatis obsolete ferrugineis, cum elytris 

 angulis non formantibus, disco obsoletius punctato : pedibus obscure ferrugineis. 

 Long. -17. 



Resembles H. americanus, but is darker colored, and less convex ; the punctuation 

 of the thorax is less distinct in the middle, that of the elytra less dense ; there are 

 traces of a stria I way between the suture and margin. 



$ pube breviore indistincta puncturaque sparsiore differt. 



^'^ H. puberulus. — Elongato-ovalis, minus convexus, niger minus dense punctatus 

 pubescens, thorace lateribus rotundatis cum elytris angulum formantibus, disco minus 

 punctato, elytris parallelis, apice oblique attenuatis ; antennis palpis pedibusque rufis. 

 Long. "12. 



Resembles the two next, but is narrower, a little more convex, the posterior angles of 

 the thorax are somewhat obtuse, and the sides form an angle with the elytra. 



■*8 H. caliginosus. — Ovalis minus convexus niger nitidus, minus subtiliter punctatus, 

 sparseque pubescens, thorace lateribus obliquis vix rotundatis. disco obsoletius punc- 

 tato ; elytris basi vix conspicue angustatis, apice oblique attenuatis : antennis palpis 

 pedibusque rufis. Long. -14. 



More convex than the following, less parallel and more acute behind : the punctures 

 of the elytra are much larger and more distant. 



■*9 H. tartaricus. — Ovalis fere ellipticus, depressiusculus, niger minus dense subtilius 

 punctatus, sparseque pubescens, thorace lateribus obliquis vix rotundatis, disco obsole- 

 tius punctato, basi depressa, elytris parallelis, apice subrotundatim attenuatis, anten- 

 nis palpis pedibusque rufis. Long. -14. 



S nitidus : 9 subtiliter alutacea, opaca. * 



"" H. varians. — Ovalis, modice elongatus minus dense punctatus, vix conspicue 

 pubescens, thorace nigro, punctis in disco sparsioribus, lateribus rectis subobliquis, cum 

 elytris angulum obtusum formantibus ; elytris lateribus parum rotundatis, apice vix 

 oblique attenuatis, antennis palpis pedibusque testaceis. Long. -12. 



a Capite elytrisque testaceis, his margine, maculaque communi pone medium piceis. 



(i Capite rufo, elytris nigro-piceis, versus basin indeterminate piceis.
