THE CANADIAN ENTOMOLOGIST. 123 



England Farmer, and in 1841 erected the genus Hyphantria for it, also 

 placing in it punctatissima, A. & S. 



In 1855, Walker described his Spilosoma congrua as quoted by Dr. 

 Fyles on page 99 of Vol. XXXI. , Can. Ent. 



In 1856, Fitch described H. punctata in his 3rd Report on the 

 Insects of New York, p. 387. 



In Grote «& Robinson's list of Bombycidte of 1868 they listed 

 Spilosoma virginica, congrua, vestalis, and Hyphantria textor, punctata, 

 cunea, with punctatissima as a synonym of cunea. Of S. congrua, these 

 gentlemen wrote in Trans. Amer. Ent. Soc, II., 72 (1868), as follows : 



"Spilosoma congrua. Walk., (c) = $ Spil. virginica (Fab.), Walk. 

 Specimens a and b appear to belong to a species distinct from S. 

 virginica, which should retain the name proposed by Mr, Walker. Our 

 notes on these two specimens are as follows : ' S. congrua ( J ). Primaries 

 white, with sparse brown dots and an S-shaped subterminal brown line, all 

 incomplete. Abdomen entirely white. Faint discal marks on both 

 wings, wanting in the female. Primaries ( $ ) with but one or two dots, 

 almost immaculate. Secondaries immaculate in either sex. Inwardly the 

 fore coxce and femora are dark yellow, without the black spot of S. 

 virginica. All the tarsi and fore tibise are inwardly brown. The ^ has 

 faint discal marks on both wings, wanting in 9 • This species seems 

 slighter than S. virginica, and approaches Hyphantria cunea in the mark- 

 ings of the primaries, but is stouter than that species, the palpi and 

 antenuje as in Spilosoma.' " 



What these authors meant by an " S-shaped subterminal brown line " 

 I do not know, as I never saw a specimen of antigone so decorated. 



But in Grote's Check List of 1882 this species was not included, the 

 Spilosomas named being virginica, vestalis and latipennis, and the 

 Hyphantrias, the same as in the list of 1868, but in a different order, 

 cunea and textor, however, being still recognized as distinct. But a few 

 months after this list appeared, Mr. Grote proclaimed the discovery of 

 S. congrua, Mr. Thaxter having reared it from the larva, and conjectured 

 that it was " very likely " the same as the form which Mr. Strecker had 

 named antigone. (Can. Ent., XV., 9, Jan., 1883.) 



In the April, 1889, number oi Efitofnologica Americana, Mrs. Slosson 

 described her Spilosoma prima. 



In June, 1889, Mr. J. B. Smith published a note on Spilosoma 

 congrua, Walk., in Ent. Amer., V., 119, arguing that Walker's description
