The Moths (Heterocera) of Eastern Pennsylvania. 



BY PHILIP LAURENT. 



The following list, although of a preliminary character, is 

 nevertheless, as complete as it is possible to make it at the 

 present time. No doubt future research will add many species 

 to the list, as many species known to occur on the other side 

 of Pennsylvania's boundary line will eventually be found in 

 Eastern Pennsylvania. The Micro-Lepidoptera, for some reason 

 or other, have been shunned by the majority of Pennsylvania 

 " field workers," so that the list is rather small and represents 

 but a small portion of the species that undoubtedly are to be 

 found in this part of the State. In the present list I have 

 only admitted such species of which I have positive proof of 

 their occurrence in Eastern Pennsylvania, no species being 

 listed on account of the fact that it is known to occur in 

 adjacent States. It is hoped that the list will not only prove 

 interesting, but useful, particularly to those who are inter- 

 ested in the geographical distribution. The basis for the 

 present list is principally the collection of the Amer. Ento. 

 Soc., and the material contained in my own collection. To 

 Mr. Chas. Blake, Mr. James Johnson, Mr. Conradi, Dr. Henry 

 Skinner, Prof. Chas. Johnson, Mr. Philip Nell and Mr. Frank 

 Haimbach, who gave me free access to their collections, and 

 assisted me in the preparation of the list, I am greatly in- 

 debted. To Prof. John B. Smith, Prof. Fernald and the late 

 Rev. Geo. D. Hulst I am under great obligations for their 

 kindness in identifying much of the material in my collection, 

 and I take this opportunity to thank all of these gentlemen 

 for kindnesses rendered. It is my intention to publish at no 

 distant date a supplementary list, and I, therefore, request the 

 reader to inform me of any inaccuracies that may be observed 

 in the present list ; which I think will prove to be but few 

 and far between. No doubt many of the species marked rare 

 are only rare in our collections, and when we learn when and 

 where to look for them they will prove to be common enough. 

 The list is arranged in accordance with Prof. John B. Smith's 

 list of the ' ' L,epidoptera of Boreal America. ' '
