Genus. — Heliomanes, Newman. 



This genus is established in the 'Annals of Natural History,' v, 17, 

 for the reception of a new species from New Holland; the typical 

 species however is Heli. minor, the Necydalis minor of Linneus, 

 ' Syst. Nat.' i. 641. The other ascertained species are Heli. umbella- 

 tarum, the Nee. umbellatarum of Linneus, ' Syst. Nat.' /. c, both of 

 these are natives of Europe and Great Britain ; Heli. sidus of Newman, 

 from New Holland, 'Ann. Nat. Hist.' /. c. ; Heli. himaculatus, the Nee, 

 bimaculatus of Say, inhabiting the northern states of the Union : and 

 many other species from the new and old continents, at present only 

 indicated by MSS. names. 



Genus. — Necydalis, Linneus. 



The genus Necydalis was established by Linneus in the ' Systema 

 Naturae,' 12th edit. i. 641, where it is divided into two sections, the 1st 

 including the species major, minor, and umbellatarum; the 2nd, a 

 variety of Heteromerous beetles which are not now considered as be- 

 longing to the Macrocerous Coleoptera. In the ' Systema Eleuther- 

 atorum,' ii. 375, we find that Fabricius has without reason assigned a 

 new generic and two new specific names, changing Necydalis into 

 Molorchus, major into abbreviatus, and minor into dimidiatus : he has 

 however retained the name Necydalis for the 2nd or Heteromerous 

 division, and to Molorchous (the proper Necydalis) he has added a 

 fourth species, variegatus, from New Holland. This insect is record- 

 ed by Fabricius as being in the Banksian cabinet, but I have in vain 

 searched that collection, which is now in the possession of the Linnean 

 Society of London. Audinet-Serville, 'Ann. Ent. Soc. of France,' has 

 very properly restored the Linnean names, but has left the genus, as 

 regards its contents, untouched. In the ' Annals of Natural History,' 

 V. 17, I have divided the genus, retaining only the tj;pe, Necydalis 

 major of Linneus, a European species, and adding a second, Necy. 

 auricomus, a native of New Holland. 



Genus. — Hesthesis, Newman. 



In the 'Annals of Natural History,' v. 17, I have proposed this ge- 

 nus for the reception of Hes. ferrugineus, the Molorchus ferruginous 

 of MacLeay, described by Boisduval in his ' Faune de I'Oceanie,' p. 

 487 ; Hes. cingulatus, the Molorchus cingulatus of Kirby, ' Trans. 

 Linn. Soc' xii. 470 ; Hes. variegatus, the supposed Molorchus variega-
