PUBLICATIONS OF THE ENTOMOLOGIST DURING THE 



YEARS 1870-1874. 



{First Observation of Pieris rapse in New York.] (Sunday Morn- 

 ing Press [Albany, j^. Y.], for August 7, 1870, p. 4.) 



Examples of this butterfly, introduced from Europe into Quebec about the 

 year 1857, were taken within the city of Albany a few days since, and could 

 be seen at the New York State Museum of Natural History. 



•*' The Poisonous Cabbage- Worm." (Albany Argus, for October 



20, 1870.) 



Newspaper statements of the poisonous nature of the Pieris rapoe larva, 

 and of its poisoning the cabbage on which it feeds, are entirely unwar- 

 ranted and untrue. Its excrement may render the cabbage unsuitable for 

 table use unless properly cleansed. What the cabbage-worm is, how it was 

 introduced and has been distributed, and the injuries caused by it. 



The Eecently Imported Cabbage-Butterfly — Pieris rapse. [Kead 



before the Alban}" Institute, November 2, 1870.] (The Albany 



Argus, for November 2, 1870. Proceedings of the Albany 



Institute, i, 1873, pp. 199-201.) 



First seen in Albany in the summer of 1870; brought to the United States 

 in 1857; its distribution; its transformations and hfe-history; probabihty of 

 its spread throughout the United States; no parasite yet attacking it. 



On Graptae interrogationis and Fabricii Edw. (Transactions of 

 the American Entomological Society, for December, 1870, iii, 

 pp. 197-204.) Separate with cover and half-title. 



Exception is taken to the conclusions of Mr. W. H. Edwards that the 

 black-winged Grapta (umbrosa) is the interrogationis of Fabricius, and the 

 red-wing, the C-aureum of the same author. The uncertainty and confusion 

 among different authors as to C-aureum is reviewed. The umbrosa form 

 seems not to have been described by any of the old authors. [It subsequently 

 proved to be a dimorphic form of G. interrogationis, as shown by Mr 

 Edwards.] 



Spectrum femoratum. ' (Country Gentleman, for August 31, 1871, 



xxxvi, p. 552, c. 2 — 2 cm.) 



Identification of the species from Columbia, Missouri. It is commonly 

 known as the " walking-stick" or "spectre-insect."
