XXII. — Systematic Notes on Coleoptera of the Clavicorn 

 Families. By GILBERT J. ARROW. 



(Published by permission of the Trustees of the British Museum.) 



The following notes have been made at various times during 

 several years past and are now published in order that the 

 synonymy may be included in the forthcoming ' Catalogus 

 Ccleopterorum.' 



SilphidaB. 



Silpka siiperba, Kraatz, 1876, is S. ccelestis, Dohrn, 1875. 



SVpha tetraspilota, Hope, 1835, is S. rufitJiorax, Wied., 

 1823. 



Siipha formosa, Cast. (= chloroptera, Cast.), is not synony- 

 mous with S. tetraspilota^ Hope, as given in the Munich 

 Catalogue. 



Silpha discicollis, Brull^, appears in that Catalogue as a 

 synonym of S. cayennensis, Sturm, but from the figure and 

 description that seems hardly possible. S, cayennensis has 

 a transversely oval pronotum, with a small dark spot in the 

 centre. 



Silpha melanura^ Hope, Gray's ' Zoological Miscellany,' 

 1831, p. 21, is omitted from the Catalogue. It is a very 

 well-marked species, rather resembling S. punctulata, Oliv. 



Silpha cceruleoviridans, Dohrn, 1885, is S. micans, F. 



Ptomascopus carbunculus, Lewis, is L. morio, Kraatz, 

 1877. Mr. Lewis was deceived by his specimens bearing 

 the locality " Amazons." This is certainly incorrect. 



Necrodes osculans,Wgox?i, has a very extended distribution. 

 The British Museum contains specimens from South India, 

 Sarawak, Woodlark I., and Queensland. 



Necrodes brevicollts, sp. n. 



Kiger vel piceus, antennis concoloribus, clava vix dilatata ; pro- 

 thorace valde transverse, lateribus arcuatis, basi fere recto, 

 omnino subtiliter punctato, lateribus opacis ; elytris crebre 

 punctatis, acute costatis, postice attenuatis : 



(5 , elytroriim angulis apicalibus arcuatis, femore postico incrassato, 

 subtus acute dentate, tibia postica fortiter arcuata, intus pest 

 medium dentata. 



Long. 15-17 mm. ; lat. mas. 6-6-5 mm.
