lucanid.k. 

 Lucanus placidus Sdv. — This year for tlie first time I took quite a 

 number of this species at electric light and also dug out some at the 

 roots of a standing dead tree. The female seems to be very rare, as 

 forty-nine out of fifty specimens were males. 



ScARAB.t:il).'E. 



Onthophagus janus Paz/z. — This is the O. striatulus of Hamilton's 

 List. 



Pleurophorus ventralis Horn. —This rare insect was taken near St. 

 Vincent's by P. Jerome Schmitt. 



Euparia castanea Sen'. — Two specimens taken at Jeannette. 



Aphodius rubeolus Beauv. — Taken at electric light at Jeannette. 



Odontaeus filicornis Say. — A rare insect at Jeannette, 1 know of 

 but few sj^ecimens having been taken. 



Trox sordidus Lee. — I have some of these, and consider it not rare. 



Amphicoma vulpina Hentz. — The only specimen I have seen from 

 this region was taken at Greensburg, Pa., by Mr. Herbert H. Smith. 



Hoplia var. tristis Melsh. — This variety I usually find on roses. 



Dichelonycha testacea Kirby. — Rather common here in spring be- 

 fore the other commoner species appear. 



Dichelonycha sp.? — An almost black species occurs here which Dr. 

 Hamilton thought to be eanadcnsis ; I am not certain that the name 

 is correct. 



Lachnosterna congrua, hornii, knochii, ephelida, and two other 

 species as yet undetermined occur here rather sparingly. 



Cyclocephala immaculata and Ligyrus gibbosus have been found 

 at Jeannette at electric light for the first time this summer (igoo) ; 

 a number of each were taken. 



Aphonus castaneus Melsh. — Three specimens dug out from the 

 roots of weeds. 



Euphoria var. nigripennis. — This black form of inda is rare here ; 

 there are no intermediate forms, as in some of the southern species. 

 Taken in September on the bark of willow trees near water. 



Cerambycid^. 

 Tragosoma pilosicornis Cas. — Two specimens were taken in Pitts- 

 burgh. It is erroneously quoted as depsarium on Dr. Hamilton's list. 

 This species can easily be distinguished by Mr. Casey's description.
