20 Mr. C. J. Galian on Longicorn Coleoptera 



with typical specimens of Plocederus nitidus^ a species which 

 I regard as synonymous with Plocederus ferrugineus, Linn, 

 (see Ann. & Mag. Nat. Hist. ser. 6, vol. v. p. 51). The 

 species with its synonyms and varieties may therefore be 

 written as follows : — 



Plocederus ferrugineus^ Linn. 



= Ceramhi/x feiTuyineus, Linn., Oliv., et Fabr. 



= Cerambyx gi</as, Fabr. 



=Lamia umbrinn, Dalm. iu Schonli. Synonym, i. 3, Appendix, p, 161. 



= Hammativherus nitidus, Wbite. 



Var. P. versutus, Pasc. (Ceramhyx). 



Var. P. niger (Chevr. MS.), Gahan, /. c. p. 51. 



I have to thank Prof. Am-ivillius for also pointing out that 

 Ccelodon rusticum, Fahr., is a species of TaurotaguSjVery 

 closely allied to T. Klugii, Lac. 



To Dr. Fr. ]\leinert, of Copenhagen, I am indebted for 

 information concerning the type specimens of Ceramhyx holo- 

 sericeusy Fabr. Two specimens from Tranquebar are ticketed 

 as types ; in one the intergenal groove is straight, in the other 

 it is distinctly bowed backwards. I do not believe that these 

 two conditions occur in the same species ; and I take there- 

 fore as representing holosericeus^ Fabr., that specimen in 

 wliich the intergeual groove is straight. The amended 

 synonymy of the species may thus be written : — 



u^olesihes liolosericeus^ Fabr. 



= Ceramhyx holosericeus, Fabr. (nee Oliv.). 

 =Pachydissus velutinus, Thorns. 

 = Pachydissus shnilis, Gahan. 



=Neocerambyx holosericeus, Cotes, Ind. Mus. Notes, vol. i. no. 2, pi. v. 

 %.3. 



To the synonymy of Plocederus fulvicornis^ Gu^r. [ — rufi- 

 cornisj Newm.), may, I think, be added P. pruinosus^ Pasc. 

 ( Ceramhyx) . 



In Lacordaire's subdivision of the genus Plocederus 

 (Genera 8, p. 255) there is a misleading error with regard to 

 the type species, P. cyampennis, Thoms. This species is 

 placed in the first division of Section A, whereas it should 

 come in the second division of the same section. P. niiidi- 

 pennis, Chevr., was in all probability the species mistaken 

 by Lacordaire for cyatiipenm's, Thoms. 



Neoceramhyx grandis, sp. n. 



Magnus, sericeo-aurato dense pubescens; capita supra inter oculos 

 leviter augustimque sulcato, sulco inter antennas descendente;
