respects of generic importance. Owing to this suspicion I have 

 included among the new species under Caulohius (below) some 

 species which I place in the genus only provisionally (as probably 

 congeneric with C. cervinus, Burm., ? Boisd.), but for which I 

 think a new generic name will be required eventually. 



JH. debilis, sp. no v. Piceo-nigra ; subsenescens ; subnitida ; capite 

 prothoraceque pilis elongatis erectis pallide brunneis, elytris 

 pilis decumbentibus griseis vittatim positis, corpore subtus 

 pedibusque pilis albidis sat crebre, vestitis; capite pro- 

 thoraceque sat crebre nee fortiter punctulatis ; hoc fortiter 

 transverso, antice angustato, lateribus leviter arcuatis, 

 angulis anticis productis posticis obtusis ; elytris obscure 

 rugulosis, 5-lineatim (plus minus ve manifeste) longitudina- 

 liter convexis, lineis glabris vix rugulosis. 



Maris clypeo antice truncato subtiliter marginato, antennarum 

 clava elongata. 



Feminse clypeo rotundato, antennarum clava minus elongata. 

 Long., 21-3 1. ; lat., li_l| 1. 



Easily distinguishable by the form of the clypeus which in front 

 is simply truncate in the male and rounded in the female with its 

 margin not reflexed. The prothorax is notably less coarsely 

 punctulate than in its allies and the tarsi are much more slender 

 than those of H. lineoligera, Blanch. 



S. Australia ; Eyre's Peninsula. 



H. Olliffi, sp. nov. Obscure viridis ; subnitida ; supra pilis 

 griseis (in elytris vittatim dispositis), subtus pilis albidis 

 vestita; capite prothoraceque grosse minus crebre punc- 

 tulatis ; hoc minus fortiter transverso, antice angustato 

 lateribus arcuatis, angulis anticis productis posticis obtusis ; 

 elytris granulato-rugulosis, 5-lineatim (plus minusve mani- 

 feste) longitudinaliter convexis, lineis glabris vix rugulosis. 

 Maris clypeo antice fortiter reflexo, producto, late truncato ; 



antennarum clava modice elongata. 

 Feminse clypeo antice vix producto, anguste reflexo, late trun- 

 cato ; antennarum clava vix minus elongata. Long., 3 1.; 

 lat.. If 1. 

 The decidedly green coloring of this species distinguishes it 

 from all its known congeners except viridis, Blackb., and the 

 clypeus of its male strongly produced and upturned in front with 

 the apex sharply truncate distinguishes it from them all. 

 Northern N.S. Wales ; given to me by the late Mr. Olliff. 

 H. lineoligera, Blanch. The synonymy of this species was 

 given wrongly by Burmeister, and has been taken over by other 

 authors from him. A very casual comparison of descriptions 

 renders this manifest, and it seems incomprehensible that Bur-
