PACHYTERIA. 163 



NOTE XXVI. 



ON SOME SPECIES OF THE GENUS PACHYTERIA 

 EROM THE OLD COLLECTION OE THOMSON. 



C. RITSEMA Cz. 



It will , I think , be already known to every student of 

 exotic Coleoptera that Mr. James Thomson has parted with 

 his beautiful collection and that it is now in the posses- 

 sion of Mr. Rene Oberthür, who in the last years increased 

 his original collection with that of de Cbaudoir, Thorey, 

 Wehncke , van Lansberge , von Harold , de Bonvouloir , 

 Gehin a.o. Being now about to arrange his Cerambycidae 

 Mr. Oberthür wrote me that the species identified by me 

 as Pachyteria voluptuosa Thoms. bears in Thomson's col- 

 lection the name of Pachyteria fasciata Fabr., whilst on 

 the other hand a specimen of the species that I believe 

 to be the fasciata of Fabricius is indicated in the same 

 collection as the type of Pachyteria voluptuosa Thoms. In 

 the meantime Mr. Oberthür most obligingly communicated 

 to me , besides some other very interesting Cerambycini , 

 the type-specimen of Thomson's Pachyteria voluptuosa^ as 

 well as two specimens regarded by Thomson as belonging 

 to Pachyteria fasciata Fabr. A comparison of the specimen 

 of Pachyteria voluptuosa above referred to with Thomson's 

 short description of this species on p. 568 of the»Systema 

 Cerambycidarum" fully convinced me of the fact that I had 

 the type-specimen before me , but at the same time I feeled 

 sure of its identity with Pachyteria fasciata Fabr., from 

 which identity results that Thomson had been mistaken in 



^otes from th.e Leyden JMuseum, "Vol. XU.
