XLIV. — List of Coleoptera collected in Vancouver's Island hy 

 Henry and Joseph Matthews, with Descriptions of some 

 new Species. By Dr. J. L. Leconte, Philadelphia. 



By the kindness of my friend the Rev. A. Matthews, I have 

 been permitted to examine a very interesting series of Coleo- 

 ptera collected by his brothers Henry and Joseph Matthews in 

 Vancouver's Island and British Columbia. Though pertaining 

 to the same zoological district as Oregon and Washington 

 Territories, several species not yet obtained from other locali- 

 ties occur in Messrs. Matthews's collection ; and, what is of 

 equal interest, several species known from the eastern and 

 central parts of the continent have been found to extend their 

 range to the Pacific slope. 



Among the former, Zacotus Mattheiosii (a magnificent copper- 

 colom'ed Broscide, resembling in form Promecoderusj but allied 

 by generic characters to Miscodera) stands preeminent as one 

 of the most remarkable additions recently made to the North- 

 American insect-fauna. Of those which have been found to 

 extend their western range beyond the limits within whicii 

 they were previously known may be mentioned : — Xchria 

 mossta, Psydrus pticeuSj Platynus cup)rip)ennisy P. hemhidioideSj 

 Anisodactylus nigrita, Dytiscus Ilarrisii, Leistotrophus ciiigu- 

 latus, Elater apical us j Corynihites infiatiis, Clerus nubilus, 

 Tricrania Stansburii, Tragosoma Ilarrisii, Acmo'ops strigilata, 

 Callidium janthinunij Monohamuius scutellatus, Saperda calca- 

 rata^ Platyrhinus ? fasciatus. 



The occurrence in a far northern locality of such forms as 

 Omus Audouinii and Dejeanii, Proniecognathus hevissimus, 

 Amara californica, ChUcnius harpalinus, Dichirus piceus, 

 NecropJiorus nigrita, Necrophilus hydrophiloides^ Odondeus 

 ohesus^ Polycaon Stoutii, Coelus riliatusj delocnemis dilati-
