Delaware (New Castle) ; Maryland (Faulkner, Hurlock, Baltimore, Rockville, Smithsburg) ; 

 Virginia (Buekner, Lloyds, Bluestone, Robious, Fort Royal) ; District of Columbia (Washing- 

 ton) ; West Virginia (Wytheville) ; Obio (Knoxdale, Hicksville, Dayton, Bremen, Toledo) ; 

 Illinois (Alma, Mokena, Downers Grove, St. Joseph); Indiana (Coatesville, Freetown); Mis- 

 souri (Reeds, House Springs, Andras) ; Minnesota (Winona, Duluth) ; Wisconsin (River Falls) ; 

 Michigan (Brant, Pioneer) ; North Dakota (Dickinson) ; South Dakota (Huron, Rapid City) ; 

 Iowa (Albia); Nebraska (Calaway, North Loup, Lexington, McCook, 

 Belvidere) ; Kansas (Great Bend, Burlington, Emporia, Kinsley) ; Okla- 

 homa (Thurston, Adair) ; Texas (Hockley, Galveston, Dime Box, Boerne, 

 Flatonia) ; Arkansas (Fallsville, Taylor) ; Mississippi (Chatawa, Pasca- 

 goula, University, Holly Springs, Pass Clrristian) ; Louisiana (Collings- 

 burg, Montgomery) ; Florida (Freeport) ; Tennessee (Limestone, Devalls 

 Bluff); North Carolina (Wilkesboro) ; South Carolina (Bluffton); Ken- 

 tucky (Milton); Montana (Helena). The record from Helena, Mont., 

 was based on a specimen sent by Messrs. Child and Jones, and deter- 

 mined as S. cecropia by Prof. Comstock in 1880. The record from 

 McCook, Nebr., was based on data supplied by Miss S. M. Le Hew, which 

 were considered at the time (1889) to indicate S. cecropia. It seems pos- 

 sible that north of Colorado S. cecropia may in part invade the territory 

 of S. gloveri; perhaps it has spread westward in recent years. I recently 

 asked Prof. M. H. Swenk, of the University of Nebraska, to give me the 

 Nebraska records for cecropia and gloveri. To my surprise he replied that 

 there was no definite record of gloveri for that State, but that cecropia 

 occurred throughout. His data (given July 22, 1912) are quoted in full, 

 as they are likely to be of historic interest hereafter: "We have over- 

 whelming evidence that this insect occurs throughout the State and is as abundant in 

 western Nebraska as in eastern Nebraska, if not more so; in fact, in some localities it is 

 abundant enough to be a pest on orchard and shade trees. Here at Lincoln we have found 

 it very common and it is abundant in the vicinity of Omaha. Mr. R. W. Dawson, my 

 assistant, tells me that he found it common in Sioux County during different years, both in 

 Warbonnet Canyon hi the Hat Creek Basin and at Glen. In 1905 at Gordon, Sheridan County, 

 he found these larvae very abundant, thousands of them on the trees in town, which were being 

 badly defoliated. Looking over my economic record I find the following instances of occurrence 



in damaging numbers in western Nebraska: At Rushville, 

 Sheridan County, June 17, 1908, Mr. S. B. Higgins sent larvae, 

 and reported it as injuring his apple trees, and stated that it had 

 done so for two years past. At Sidney, Cheyenne County, 

 April 24, 1909, Mr. L. Bordwell reported these larvae as greatly 

 injuring the trees in that vicinity. From Bigspring, Deuel 

 County, September 13, 1908, Mr. E. F. Stevens sent specimens 

 and said the worms were destroying his plums. From Stratton, 

 Hitchcock County, Mr. T. E. Wellman sent cecropia cocoons 

 March 7, 1910, with a statement that the insect injured plum 

 foliage in that vicinity. From North Platte, Lincoln County, 

 August 27, 1909, Mi - . Frank Soukup sent specimens and 

 reported the insect injuring box elders and honey locusts. 

 September 4, 1908, Mr. F. C. Stoner sent specimens from 

 Sumiyside, Brown County, with a statement that the larvae were eating the foliage of his 

 fruit trees. We have also received specimens from Blue Hill, Nelson, and Inavale, with 

 similar reports. Along with your card requesting this information comes a letter from Mitchell, 

 Scotts Bluff County, within a few miles of the Wyoming line, accompanied by a specimen of the 

 cecropia moth for identification. If you will note these localities you will see that they embrace 

 practically all sections of western Nebraska, and from the reports the bisect is abundant enough
