VIII. SUPPLEMENT TO DR. JOHN HAMILTON'S LIST 



OF THE COLEOPTERA OF SOUTHWESTERN 



PENNSYLVANIA. 



I'.v Henry G. Klages,' Jeannette, Pa. 



Seven years have elapsed since the publication of Dr. John Hamil- 

 ton's List of the Coleoptera of Southwestern Pennsylvania/ and dur- 

 ing these years many species have occurred here, which were not 

 noted at the time of that publication. The most of these have been 

 collected in the vicinity of Jeannette, and in the mountainous region 

 near St. Vincent's Abbey. I'he species taken in the latter place have 

 been collected by Rev. P. Jerome Schmitt, O.S.B., and his able as- 

 sistants. Rev. P. Marcellus Rettger, O.S.B., and Rev. P. Richard 

 Kraus, O.S.B. Some of the species recorded in the former list have 

 not been taken here for many years ; while others not recorded, or 

 considered rare, are now commonly found. 



That all the species on this list ought to be regarded in a strict 

 sense as local species, I cannot say, as, in many cases, only a single 

 specimen has been obtained, which might, indeed, have been intro- 

 duced in one or the other of several ways. Insects may, perhaps, be 

 introduced by the wind-storms, which sweep the Ohio valley, and also 

 by trains (as the passenger-coaches of night-trains, on arriving at 

 Pittsburgh during the summer months, are frequently found to contain 

 hundreds of insects). Food supplies, such as tropical and dried iVuit 

 and imported nuts, often introduce species, which in some cases are 

 perpetuated. 



The region in which most of these species were collected is hilly 

 and mountainous, and lies at a considerably higher altitude than the 

 environs of Allegheny where most of Dr. Hamilton's collecting was 

 done. Many of the species are monticolous, and years of careful col- 

 lecting in the country near St. Vincent's Abl)ey have added many species 

 new to science, and have largely increased our local list of insects. 



' The lists of the Scydmsenidae and Pselaphidje, together with the notes on these 



families, are from the pen of Rev. Jerome Schmitt, O.S.B. , of St. Vincent's Abbey.
