20 RKVISIOX OF TUK AMYCTERIDES^ vi., 



"Genre Acantholophe, Acaniholuphus, Schon. nianuse. Ce geme n'etait pas 

 encore publie quand nous avons clonne eet article a I'impression, cependant M. 

 Boisduval, charge par M. Schoenberr de surveiller I'impression dc I'ouvrage de ce 

 savant nous a assui'e qu'il etait etabli dans le manuscrit <iui s"imprime actuelle- 

 inent (15 decembre 1833). 



Le genre Acantholophe se rapproche beaucoup des Amyeterus de Schonherr, 

 mais ses antennes longues et greles Ten distinguent d'une maniere bien nette." 



These brief notes, though hardly a chai-acterization of the genus, seem almost 

 sufficient to validate the use of the name, provided that the identity of A. echin- 

 atus Guer. ciin be tised. 1 cannot find, however, that the genus was described by 

 Schouhen- at this date, as stated by Guerin-Meneville. In Schonherr's Gen. et 

 Spec. Cure, ii., published in 1834, which is presumably the work to which 

 Guerin-Mfoeville refei-s, Curculio marshami Kirby was redeseribed by Gyllenhall, 

 who placed it in the genus Amyeterus. 



In 1835 BoLsduval (Voy. de 1' Astrolabe, ii.. pp. 369-371) referred two species 

 to the genus — mamluimi and ecliiiiatus. He did not, however, ehai-aeterise the 

 genus beyond a short note. — "Les insectes de ce genre ont pour les caracteres les 

 plus gi-ands rapports avec les Amyeterus de Schonherr, et pour le fades una cer- 

 taine ressemblance avec les Sepidium."' 



(Jwing to the uncertainty in regard to Guorin's date of publication, it is 

 quite possible that Boisduval's use of the name will have priority. 



The (]uestion of the date of the drst use of the name is of some importance 

 as Pascoe (Journ. Linn. Soc, Zool., xii.. 1873, p. 7) has pointed out that the 

 name Acanthulvphus was utilised by Koch in 1837 for a genus of spiders, 10 

 years before Schonhen- characterised the present genus. I hold, however, that 

 Boisduval's use of the name for two species is sufficient to justify its adoption, 

 even if the date of Guerin-Meneville's publication is found to be later than the 

 date of Koch's use of the name. If Guerin Mcneville antedates Boisduval, the 

 position is made more secure. 



The first species describeil that can be a.ssigned to this genus was Ctirculio 

 ma rah a mi Kirby published in Trans. Linn. Soc, xii., 1818, p. 436. Followmg 

 this, two, if not more, species appear to have been described under the name of 

 Acanthohiphus echi)iatu.s by Guerin-Meneville (Voy. de la Coijuille, ii., p. 1'22) 

 and Boisduval (Voy. de I'Astrolaljc, ii.. 1835, p. 371). A full discussion of the 

 use of the name is given later under ,1. echinatus. 



Bohemann (Sclionh. Gen. f>\)vr. Cure, vii., 1, (1843), i>])- 72, 74-79) dcsciil)ei! 

 7 species, under the genus A mycterns, which were subsequently removed to Acan- 

 Iholophua wiien that genus was formally described by Schonherr in 1847 (Mantissa 

 Seeunda Kamiliae Curculionidum, p. 55). These species are aureolus, hlvittatus, 

 dumonna, hypolcucus, hyulrix, lateralis, and xuturalis. 



In 1854, G. R. Waterhouse (Trans. Ent. Soc., iii., part 2) described two 

 new species, adelaidae and planicoUif:. and gave a table grouping together the 

 known species of the genus, but also including under III. B, several species now 

 placed in Cubieorrhynchus. 



Lacordaire, in his work (Gen. Coleopt., \i., p. 311, 1863). gave a lengthy 

 description of the genus, without adding any new species to it. He also noted 

 that several of the species ascribed to tlie genus mij;lit be better sejiarated generic- 

 ally; the only one of these with wliicli he wai; ac(|uaintc<l was .1. platiicolli.',- Water- 

 house. Tliis and allied species I have in the present iiaper placed in a sei)arate 

 section of the genus. Maeleay (Trans. Ent. Soc. N.S. Wales, i., 1865, pp. 

 270-290) descrilied 22 new species, — frnw.sftu.s, amyeteroides, spincsris, cra-'ssidenx,
