THE CANADIAN ENTOMOLOGIST. 199 



The resemblance of the Quebec Spilosoma to Drury's is superficial — 

 " most superficial." 



The size is the same. 



The contour is the same. 



The coloration is the same. 



The arrangement of the spots is the same. 



The triangle is in the right place. 



The variation in the abdomen is accounted for, and there is no 

 straining to fit an extreme variety, or a spotless female, into the case. 



What the resemblance i/iferHa//_y may be, I cannot say. I must leave 

 Mr. Lyman to find out. And with this parting shot, I retire from the 

 field — my guns uncaptiired ; my forces unbroken. 



DESCRIPTION OF PLATE 4. 



The plate is made from an admirable photograph taken by Prof. H. 

 Walters, M. A., Morrin College. The figures of the moths are of the 

 natural size. 



Jigs. I and 2 represent Hyphantria textor, Harris. The insects 

 were raised at Levis by myself. 



Figs. 3, 4, 5 and 6 show specimens of Spilosoma congrua, Walker. 

 One m.ale is all but immaculate — it has a tiny dot at the angle of the 

 second fork of the median nerve. The abdomen of the insect represented 

 was originally pure white ; it is now yellow, white at the edges of the seg- 

 ments and towards the tip. The other male represented is more spotted, 

 and has now an ash-coloured abdomen with longitudinal rows of spots. 

 One female answers to Grote and Robinson's description. The other is 

 more spotted. 



Figs. 7 and 8 represent a pair oi Hypliantria pundatissima, S. and A. 

 The moths were sent to me by Mr. H. H. Newcomb, of Boston, and were 

 raised by Miss Emily L. Morton, of New Windsor, N. Y. Miss Morton 

 says of these insects : " I have raised a great many of them, and there is 

 very little variation ; the female is invariably immaculate." 



In Figs. 9 and 10 a pair of the Spilosomas we have had under 

 consideration are seen. The male was taken at Bergerville, Quebec, by 

 Miss Bickell ; the female was taken at Bourg Louis, Quebec, by Edgar 

 Walters. In the Plate the black pectinations of the antennae of the male 

 do not show against the dark background. T. W. F.
