fflSTORY. 



This species was first described by Walker, in 1863, under the 

 name of Nephopteryx semifuneralis. In 1881 Zeller redescribed and 

 figured it as Euzophera impletella. In 1887 Hulst described the 

 species as Stenoptycha pallulella. In 1889 we find the first published 

 reference to the immature stages of this insect; S. A. Forbes, in his 

 report for that year, described the larvae as injuring Chinese plum 

 (Prunus simoni) in Illinois. Forbes gave it the common name of 

 American plum borer. In 1891 D. S. Kellicott reported it as injuring 

 mountain ash in Ohio, and in 1898 Otto Lugger included it in a list 

 of "Butterflies and Moths Injurious to our Fruit Producing Plants." 

 In 1901 E. D. Sanderson reported it as injuring apple and Kieffer 

 pear in Delaware, giving a few notes on its probable life history in 

 that locality and renaming it the "fruit-tree bark borer." Slinger- 

 land and Crosby have given a short account of this borer in their 

 1 recent "Manual of Fruit Insects." 



While Forbes' s report is the first published reference to the feeding 

 habjts of the larvae of this insect, we find in the unpublished notes of 

 the Bureau of Entomology, February 2, 1879, the following note: 

 "Received from E. A. Schwarz, Jackson, Miss., one cocoon found 

 under bark on fence around cotton field. The moth issued and 

 proves to be either M. distinct ella, or one that comes very near to it." 

 This specimen was later determined by H. G. Dyar to be Euzophera 

 semifuneralis Walk. Again, May 14, 1 879, in the notes of the Bureau of 

 Entomology, Theo. Pergande records finding a cocoon on peach and 

 rearing a moth belonging to the Pyralidse, which he names rather 

 doubtfully Acrobasis sp. A later determination by Dyar proved 

 this also to be Euzophera semifuneralis. 



' DISTRIBUTION. 



Dyar gives the distribution of this borer as "United States." 

 Zeller described the species in 1881 from four specimens from Colom- 

 bia, South America, one of which was taken at Mariquita on August 

 10 and the other at Honda the last of April. Hulst notes that his 

 description was based on specimens from New York, Utah, and Wash- 

 ington. In the United States, specimens in the collection of the 

 United States National Museum, and the correspondence, notes, and 

 collection of the Bureau of Entomology, as well as the literature 

 available, indicate that the insect occurs in the following States: 

 Arkansas, Arizona, Colorado, Delaware, Florida, Georgia, Illinois, 

 Indiana, Kansas, Missouri, Maryland, Mississippi, North Carolina, 

 New York, Ohio, South Carolina, Texas, Utah, Virginia, West Vir- 

 ginia, Washington, and the District of Columbia.
