94 THE CANADIAN ENTOMOLOGIST. 



(a) A male specimen of S. Antigone, Strecker, presumably of the 

 type which Dr. Fyles described under the letter f. 



(b) A female specimen of the heavily-spotted Gomin type of 

 Spilosoma. 



(c) The specimen of .S. Virginica without abdomen, as described by 

 Grote & Robinson. 



On my return to Montreal, I looked up the description given 

 by Grote & Robinson of the types a-b, to which they restricted the 

 name Congrua, as quoted by me (Can. Ent., XXXII., 123), and saw at 

 once that there must be some mistake, as they described the type b as : 

 " Primaries with but one or two dots, almost immaculate. Secondaries 

 immaculate in either sex." I therefore wrote to Sir George Hampson, 

 who admitted that the heavily-spotted specimen was probably not one of 

 the types of Congrua, especially as he found that the locality label on the 

 pin was New York, while the types were said to have come from Georgia. 

 I only mention this to show how necessary it is to " prove all things," as 

 uve are exhorted to do by the apostle. Subsequently I was able to return 

 rto England for a brief visit, and shortly before my return home spent two 

 or three hours at the Museum, and made an exhaustive examination of 

 the specimens of Spilosoma and Hyphantria, and came to the conclusion 

 that type b must have been destroyed, as I could find no specimen in the 

 collection which would at all answer the description given by Grote <S; 

 Robinson. The type specimen a is numbered 947, and is shown both 

 by the date upon the label and by the Register to have been acquired on 

 19th June, 1839, at the sale of Mr. Milne's collection, at which a consider- 

 able number of specimens were obtained. It is entered in the Register 

 merely as Arctia. It expands about if 1 ,., inches, and answers fairly well to 

 the description given by Messrs. G. & R. 



Type specimen c is a rather large specimen of S. Virginica, expanding 

 about 1 "/i inches, and is presumably a female, but the abdomen is missing. 

 This specimen is very lightly marked, having only a black point on upper 

 side of fore wing at lower angle of cell, and a black spot on the middle of 

 the discocellular vein of hind wing below. The number on label is 937, 

 and is entered as Arctia simply, and was received at the same time as 

 the type a. 



The question now arises as to the use or suppression of Walker's 

 name, Congrua.
