Burmeister, apud Westwood, Arc. Ent. I, 37, considers it as a 

 Lonjiicora . 



Guerin, Revue Zoologique, 1841, p. 217, adopts this view. 



Le Conte, Journ. Acad. Nat. Sc, Phila., 2d ser,, IT, 99, knowing the 

 insect only by figure and description, did the same. 



White. Proc. Linn. Soc, London, 1854; Annals and -^Iag. Nat. 

 Hist., 1854, p. 4G4; asserts its affinities with Prionida3. 



Curtis, Trans. Linn. Soc, London, 1854, p. 227, (figure) ; considers 

 its strongest relations to be with the LanioUicornia. 



Gerstaecker, Bericht, Ent., 1854, p. 80, reviews these two authors, 

 and disapproves of Curtis' view, while he supports Burmeistor's, men- 

 tioned above. 



Blanchard, Hist. Ins., IT, 185. 



Spinola, apud Westwood, Arcana Ent. I, 111 ; advocates its separa- 

 tion from all other Coleopterous families. 



Gistl, Faunus, II, describes it under the name Mesoclastus para- 

 doxus, as constituting a new family, Xcoomorph;ie, a name adopted 

 by Gerstaecker, in the review cited above. The figure given by Gistl 

 is quite incorrect in the form of the legs, and has been supposed to 

 indicate possibly a different species. I think, however, the picture 

 has been only idealized by an artist not trained in the severe dis- 

 cipline of scientific ob.servation. Westwood has given in Arcana Eut. 

 I, pi. 10, an accurate copy of this figure. 



Finally, Erichson in Agassiz, Nomenclator Zoologicus, has omitted 

 all reference to either the name or the synonym of this genus. 



I mu,st add in justice to those who have investigated previously this 

 subject with such signal ability, that hardly any of the affinities of ILjpo- 

 cepha/us have been unnoticed by them ; the 3U[)crior prominence, which 

 I have been able to give to its Khynchophorous cli:iracters, is owing 

 entirely to the development of the views regarding the systematic 

 value and classification of that set of Coleoptora, which I have had 

 the honor to present to you at former meetings of the Academy. The 

 opinions first expressed by Westwood, that it belonged to a series con- 

 necting PdSKaudrn, Cafof/rnus, and A'A//.sct/r.s with Cahdromua and the 

 Brenthidae, agree with those here givon, but were overborne by the 

 authority of Burmeister and others, who have maintained the relation- 

 ship with S}>ondi/lus and other members of the Lougicorn series.
